Which Of The Following Graphs Shows A Positive Linear Relationship With Acorrelation Coefficient, R,

Answers

Answer 1

Given:

The objective is to choose the correct graph which shows a positive linear relationship with a correlation coefficient, r, close to 1.

The positive linear relationship represents the increasing values of plots from origin to positive x and positive y axis.

By observing graph A, the plots are scattered all over the quadrant. Hence, it is a weak association.

By observing graph B, the plots are plotted as decreasing in y axis and increasing in x axis. Hence, it is a strong negative association.

By observing graph C, the plots are plotted as increasing in both x axis and y axis. Hence, it is a strong positive association.

Hence, the graph which shows a positive linear relationship with a correlation coefficient, r, close to 1 is graph C.

cole is studying ceramics and he was asked to submit 5 vessels from his collection to exhibit at the fair. he has 15. vessels that he thinks are show worthy. in how many ways can the vessels be chosen

Answers

Since he has 15 vessels and needs to choose 5, we can use a combination of 15 choose 5 to calculate the number of possible ways, since the order of the vessels inside the group of 5 is not important.

The formula to calculate a combination of n choose p is:

[tex]C(n,p)=\frac{n!}{p!(n-p)!}[/tex]

Then, for n = 15 and p = 5, we have:

[tex]\begin{gathered} C(15,5)=\frac{15!}{5!(15-5)!}=\frac{15!}{5!10!}=\frac{15\cdot14\cdot13\cdot12\cdot11\cdot10!}{5\cdot4\cdot3\cdot2\cdot10!} \\ =\frac{15\cdot14\cdot13\cdot12\cdot11}{5\cdot4\cdot3\cdot2}=3003 \end{gathered}[/tex]

So there are 3003 ways to choose the 5 vessels.

Can I just have a very quick simple answer to this question?

We have a feasibility region and we have to find at which point of the region the function P can be maximized:

[tex]P=3x+2y[/tex]

As this is a linear function, the maximum value will be in one of the vertices of the region. We can identify the vertices as:

We can calculate the value of P for each of the vertices and see which one has a maximum value. We can already guess that P(8,0) will be greater than P(0,8) as the coefficient for x is greater than the coefficient for y.

We can calculate the three values as:

[tex]\begin{gathered} P(0,8)=3\cdot0+2\cdot8=0+16=16 \\ P(6,5)=3\cdot6+2\cdot5=18+10=28\longrightarrow\text{Maximum} \\ P(8,0)=3\cdot8+2\cdot0=24+0=24 \end{gathered}[/tex]

Answer: the maximum value of P is 28.

To find the total surface area of this cone, we have that the total lateral area is given by the formula:

[tex]A_{\text{lateral}}=s\cdot\pi\cdot r[/tex]

Where

s is the slant height of the cone, s = 12 inches.

r is the radius of the base of the cone, r = 7 inches.

To that area, we need to add the area of the base of the cone:

[tex]A_{\text{base}}=\pi\cdot r^2[/tex]

That is, this is the area of a circle with this radius. Then, the total surface area is:

[tex]A_{\text{total}=}s\cdot\pi\cdot r+\pi\cdot r^2[/tex]

Substituting the values in this formula, we have:

[tex]A_{\text{total}}=12in\cdot3.14\cdot7in+\pi\cdot(7in)^2=263.76in^2_{}+153.86in^2[/tex]

Then

[tex]A_{\text{total}}=417.62in^2[/tex]

Hence, the total area is equal to 417.62 square inches.

How should you solve the equation x + 10 = 80? What is the resulting equivalent equation?Choose the correct answer below.

Answer:

No solution.

Step-by-step explanation:

Why I say this problem has no solution is due to the fact that the amount of pages is unclassified. This leads you to guessing how many pages there might be for each chapter of the students' individual books, and guessing would not be an effective method as it could lead you to thinking of any random number between 1 - 60 at the most. Therefore, this problem has no solution. If you have further concerns about this problem, I recommend addressing them to your teacher. Otherwise, have a great day. :)

Jacob is taking part in a month long Reading challenge at his school. He can earn point for each book he reads, up to two dozen books. As shown in the graph P (b) gives the number of points Jacob earns as a function of the number of books he reads.

Answers

Observe the given graph carefully.

It is evident that 'b' is the independent variable (representing the number of books read) for the function f(b) (representing the number of points earned).

The domain of a function is the set of all values of the independent variable that lie within the function.

The graph is plotted from x=0 to x=24.

And the number of books cannot be fractional.

So it can be concluded that the domain of the function is the set of whole numbers from 0 to 24. Also, the function is also defined at the end-points. So the set will be inclusive of the end-points 0 and 24.

Therefore, the 2nd option is correct for the first blank.

The domain is a subset of all possible values of variable 'b'. So it will represent the number of books that Jacob reads.

Thus, the 1st option is the correct choice for the second blank.

Answers

We will determine the inequality as follows:

*First: We will determine the interception point of the two equations, that is:

[tex]y=4.50x+40[/tex][tex]y=6.50x+20[/tex]

So:

[tex]4.50x+40=6.50x+20\Rightarrow4.50x-6.50x=20-40[/tex][tex]\Rightarrow-2x=-20\Rightarrow x=10[/tex]

Now, we replace x = 10 on any of the two equations:

[tex]y=4.50x+40\Rightarrow y=4.50(10)+40[/tex][tex]\Rightarrow y=45+40\Rightarrow y=85[/tex]

So, the interception point is located at (10, 85).

*Second: We determine the inequality that represents the problem, that is:

[tex]6.50x+20>4.50x+40[/tex]

[This is overall, the second equation represents greater cost].

*Third: The least number of medals that cab ve ordered so company's A cost is less than company's B cost is 10 medals.

The supplement is when two angles add up to 180° and complement is when two angles add up to 90°

let:

x = the angle.

90 - x = its complement

then x = 2(90-x) + 20 means the measure of the supplement of an angle exceeds twice the measure of the complement of the angle by 20

A model of a triangular prism is shown below. Whats is the surface area of the prism?

Answers

We are asked to find the surface area of a triangular prism. To do that we must add the areas of each of the faces of the prism, that is, three rectangles and two triangles. The area of each rectangle is:

[tex]A_{\text{rectangles }}=5\operatorname{cm}\times12\operatorname{cm}+5\operatorname{cm}\times12\operatorname{cm}+5\operatorname{cm}\times12\operatorname{cm}[/tex]

Solving the operations we get:

[tex]A_{\text{rectangles}}=180cm^2[/tex]

Now we find the area of the triangles, knowing that the area of a triangle is the product of its base by its height over two, like this:

[tex]A_{\text{triangle}}=\frac{(base)(height)}{2}[/tex]

The base is 5 cm and the height is 6cm, replacing we get:

[tex]A_{\text{triangle}}=\frac{(5\operatorname{cm})(6\operatorname{cm})}{2}=15cm^2[/tex]

Now we add both areas having into account that there are two triangles, like this:

[tex]A=A_{\text{rectangle}}+2A_{\text{triangle}}[/tex]

Replacing we get:

[tex]\begin{gathered} A=180+2(15) \\ A=210 \end{gathered}[/tex]

therefore, the surface area is 210 square centimeters

Hello for this particular problem can I change the final results to a whole number? or it is not possible?

Answers

We are asked which of the given combinations will produce a number that is less or equal to 25.

For A we have:

[tex]A=3(8\frac{3}{4})[/tex]

Let's remember that for a mixed fraction we have:

[tex]a\frac{b}{c}=a+\frac{b}{c}[/tex]

Therefore, we can change the mixed fraction and we get:

[tex]A=3(8\frac{3}{4})=3(8+\frac{3}{4})[/tex]

Solving the operations:

[tex]A=26.25[/tex]

Since we get a number greater than 25 this is not a trail he can ride.

For B we have:

[tex]B=2(10\frac{1}{4})[/tex]

Changing the mixed fraction:

[tex]B=2(10\frac{1}{4})=2(10+\frac{1}{4})[/tex]

To solve the operation we will apply the distributive property:

[tex]B=20+2\times\frac{1}{4}[/tex]

Now, we simplify the fraction:

[tex]B=20+2\times\frac{1}{4}=20+\frac{1}{2}[/tex]

Now, we use the fact that 1/2 = 0.5:

[tex]B=20+\frac{1}{2}=20+0.5=20.5[/tex]

Since we get a number that is less than 25 this is a train he can ride.

For C we have:

[tex]C=2(7\frac{1}{2})+10\frac{1}{4}[/tex]

Changing the mixed fraction:

[tex]C=2(7+\frac{1}{2})+10+\frac{1}{4}[/tex]

Now, we apply the distributive property:

[tex]C=14+1+10+\frac{1}{4}[/tex]

Solving the operations. We use the fact that 1/4 = 0.25:

[tex]C=25+0.25=25.25[/tex]

Since we get a number greater than 25 this is not a trail he can ride.

For D.

[tex]D=7\frac{1}{2}+2(8\frac{3}{4})[/tex]

Now, we change the mixed fractions:

[tex]D=7+\frac{1}{2}+2(8+\frac{3}{4})[/tex]

Now, we use the distributive property:

[tex]D=7+\frac{1}{2}+16+2\times\frac{3}{4}[/tex]

Simplifying the fraction:

[tex]D=7+\frac{1}{2}+16+\frac{3}{2}[/tex]

Now, we add the fractions, we have into account that when fractions have the same denominator we can add the numerators and use the common denominator, like this:

[tex]D=7+\frac{4}{2}+16[/tex]

Simplifying the fraction we get:

[tex]D=7+2+16[/tex]

Solving the operations:

[tex]D=25[/tex]

Since we get 25 this is a trail that he can ride.

The function we have is:

[tex]y=-x+4[/tex]

First, we need to find the rate of change of this function and then we can compare it with the rate of change of each option.

To find the rate of change, we compare the given equation with the general slope-intercept equation:

[tex]y=mx+b[/tex]

Where m is the slope, also called the rate of change and b is the y-intercept.

By comparing the two equations, we find that the rate of change is:

[tex]m=-1[/tex]

So now we will analyze the given options to see in which of them we find a rate of change of -1.

Option A:

In this option (and in option B) we have a table of values for x and y.

We calculate the rate of change by taking two (x,y) points from the table,

Here, we will take the first two (x,y) values and label them as follows:

[tex]\begin{gathered} x_1=-4 \\ y_1=1 \\ x_2=-2 \\ y_2=2 \end{gathered}[/tex]

And we calculate the rate of change "m" using the slope formula:

[tex]\begin{gathered} m=\frac{y_2-y_1}{x_2-x_1} \\ \end{gathered}[/tex]

Substituting the values we get:

[tex]m=\frac{2-1}{-2-(-4)}[/tex]

Solving the operations:

[tex]\begin{gathered} m=\frac{1}{-2+4} \\ m=-\frac{1}{2} \end{gathered}[/tex]

The rate of change if NOT -1, this option is not correct.

Option B. We do the same as in the first option.

Label the first two (x,y) values as follows:

[tex]\begin{gathered} x_1=4 \\ y_1=5 \\ x_2=8 \\ y_2=8 \end{gathered}[/tex]

And use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Substituting the values:

[tex]\begin{gathered} m=\frac{8-5}{8-4} \\ m=\frac{3}{4} \end{gathered}[/tex]

Again, the slope or rate of change is NOT -1, this is also not the option we are looking for,

Option C. In options, C and D we have a graph. To find the rate of change from the graph of a line, we take two points where the line passes, and find the rate of change as follows:

[tex]m=\frac{\text{change in y}}{change\text{ in x}}[/tex]

For the graph in C, we will take the following red points

Drawing a triangle between the points we can find the change in y and the change in x:

[tex]\begin{gathered} \text{change in y=-1} \\ \text{change in x=1} \end{gathered}[/tex]

Thus, the rate of change is:

[tex]\begin{gathered} m=-\frac{1}{1} \\ m=-1 \end{gathered}[/tex]

C is the correct option.

Wally's grandmother started a college savings account for him with $3,000. What is the total amount of money in the account after 5 years if the annual simple interest rate is 3%?

Answers

ANSWER

$3,450

EXPLANATION

She started the savings account with $3,000.

The simple interest rate is 3% and the number of years is 5 years.

To find the amount of money in the account after 5 years, we have to first find the interest and then add it to the initial amount saved.

Simple Interest on an amount of money (Principal) at a rate R for a number of years T is given as:

[tex]I\text{ = }\frac{\text{P }\cdot\text{ R }\cdot\text{ T}}{100}[/tex]

Therefore, the interest is:

[tex]\begin{gathered} I\text{ = }\frac{3000\cdot\text{ 5 }\cdot\text{ 3}}{100} \\ I\text{ = \$450} \end{gathered}[/tex]

Therefore, the amount in the account after 5 years is:

Amount = Principal + Interest

Amount = 3000 + 450

Amoun = $3,450

That is the amount in the account.

since this is a linear equation, we need to find 2 points and plot them in the chart

let's find point 1. Let's say x = 0 and replace: y = 3x+4 = 3*0 + 4 = 0 + 4 = 4

so, when x=0, then y = 4 , so our 1st point is (0,4)

now, let's suppose, y=0 , in that case, y = 3x + 4 = 0 , then 3x = -4 , so the value of x is -4/3 = -1.3333

in that case, our seconds point is (-4/3 , 0)

just to make sure, we can also plot a 3rd point, let's say we make x = 2, then y = 3*2 + 4 = 6 + 4 = 10

so, our 3rd point is (2, 10)

Answers

Answer:

[tex][d(A, B)]^2=\boxed{85}[/tex]

[tex][d(A,C)]^2+[d(B,C)]^2=\boxed{85}[/tex]

[tex]\sf Area=\boxed{17}\; units^2[/tex]

Step-by-step explanation:

From inspection of the given diagram, the vertices of the triangle are:

A = (-5, 5)B = (1, -2)C = (-1, 6)

If ΔABC is a right triangle, the sum of the squares of the two shorter sides will equal the square of the longest side.  This is the definition of Pythagoras Theorem.

Use the distance formula to find the side lengths of the triangle.

[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Distance between two points}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two points.\\\end{minipage}}[/tex]

[tex]\begin{aligned}d[(A,B)]&=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\&=\sqrt{(1-(-5))^2+(-2-5)^2}\\&=\sqrt{(6)^2+(-7)^2}\\&=\sqrt{36+49}\\&=\sqrt{85}\end{aligned}[/tex]

[tex]\begin{aligned}d[(A, C)]&=\sqrt{(x_C-x_A)^2+(y_C-y_A)^2}\\&=\sqrt{(-1-(-5))^2+(6-5)^2}\\&=\sqrt{(-4)^2+(1)^2}\\&=\sqrt{16+1}\\&=\sqrt{17}\end{aligned}[/tex]

[tex]\begin{aligned}d[(B, C)]&=\sqrt{(x_C-x_B)^2+(y_C-y_B)^2}\\&=\sqrt{(-1-1)^2+(6-(-2))^2}\\&=\sqrt{(-2)^2+(8)^2}\\&=\sqrt{4+64}\\&=\sqrt{68}\end{aligned}[/tex]

Therefore:

The longest side of the triangle is line segment AB.The two shorter sides of the triangle are line segments AC and BC.

[tex]\boxed{\begin{minipage}{9 cm}\underline{Pythagoras Theorem} \\\\$a^2+b^2=c^2$\\\\where:\\ \phantom{ww}$\bullet$ $a$ and $b$ are the legs of the right triangle. \\ \phantom{ww}$\bullet$ $c$ is the hypotenuse (longest side) of the right triangle.\\\end{minipage}}[/tex]

The triangle is a right triangle if:

[tex][d(A,C)]^2+[d(B,C)]^2=[d(A,B)]^2[/tex]

Substitute the found side lengths into the formula:

[tex]\implies [\sqrt{17}]^2+[\sqrt{68}]^2=[\sqrt{85}]^2[/tex]

[tex]\implies 17+68=85[/tex]

[tex]\implies 85=85[/tex]

Therefore, this proves that ΔABC is a right triangle.

To find the area of a right triangle, half the product of the two shorter sides:

[tex]\begin{aligned}\implies \sf Area &= \dfrac{1}{2}bh\\&=\dfrac{1}{2} \cdot [d(A,C)] \cdot [d(B,C)]\\&=\dfrac{1}{2} \cdot \sqrt{17} \cdot \sqrt{68}\\&=\dfrac{1}{2} \cdot \sqrt{17 \cdot 68}\\&=\dfrac{1}{2} \cdot \sqrt{1156}\\&=\dfrac{1}{2} \cdot \sqrt{34^2}\\&=\dfrac{1}{2} \cdot 34\\&=17 \sf \; units^2\end{aligned}[/tex]

Therefore, the area of the given triangle is 17 units².

3. Square SQRE has coordinates S(2, 2) Q (5,2)R (5. – 1). Find the coordinates of E. I gotta turn it in tomorrow

Answers

Given:

Square SQRE has coordinates S(2, 2) Q (5,2), and R (5. – 1).

To find:

The coordinates of E.

Explanation:

Let (x, y) be the coordinates of E.

Using the midpoint formula,

[tex]p=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

As we know,

The diagonals of the square are intersected by its midpoint.

So, the Midpoint of SR and QE is the same in a given square SQRE.

[tex]\begin{gathered} Midpoint\text{ of SR = Midpoint of QE} \\ (\frac{2+5}{2},\frac{2-1}{2})=(\frac{5+x}{2},\frac{2+y}{2}) \\ (\frac{7}{2},\frac{1}{2})=(\frac{5+x}{2},\frac{2+y}{2}) \end{gathered}[/tex]

Equating the coordinates we get,

[tex]\begin{gathered} \frac{7}{2}=\frac{5+x}{2} \\ 7=5+x \\ x=2 \\ \frac{1}{2}=\frac{2+y}{2} \\ 1=2+y \\ y=-1 \end{gathered}[/tex]

Therefore, the coordinate of E is (2, -1).

Final answer:

The coordinate of E is (2, -1).

Answers

Given:

the sequence shown below that starts with n = 1

[tex]1,4,9,16,25,\ldots[/tex]

The rule of the sequence will be as follows"

The first term = 1, when n = 1

The second term = 4 = 2², when n = 2

The third term = 9 = 3², when n = 3

..

..

So, the rule will be:

4. Which is the best first step to write 2(x-4)^2-3=8 in standard form?A. Factor.B. Clear the parentheses.C. Set the function equal to 0.D. Combine like terms.

Answers

We will have that the best way to write it in standard form is B, we clear the parentheses and solve for x.

*That is because the function is already factored, and we will combine like terms and equal to 0 in the remaining steps.

Christina's purchasing a new TV. She was approved to finance the TV with zero interest. If Christina gives a one-time payment of $300 and pays $65 per month, how much has she paid in 5 months? (show work)

Answers

Given:

One time payment, p = $300

Payment per month, q = $65

Number of months paid, n = 5

The objectiv is to find the amount she paid in 5 months.

Let x be the amount she paid in 5 months. Then the the formula is,

[tex]x=p+nq[/tex]

Let's substitute the values.

[tex]\begin{gathered} x=300+5(65) \\ x=300+325 \\ x=625 \end{gathered}[/tex]

Hence, total amount paid in 5 months is $625.
