Answers
Answer
a) f(5) = 12
b) f(-1) = 6
c) f(-3) = 4
Explanation
We are given the function
f(x) = x + 7
We are then asked to evaluate a number of valus of x for the function
a) f(5)
f(x) = x + 7
f(5) = 5 + 7 = 12
b) f(-1)
f(x) = x + 7
f(-1) = -1 + 7 = 6
c) f(-3)
f(x) = x + 7
f(-3) = -3 + 7 = 4

Use the given data to make a box-and-whisker plot.5, 4, 16, 21, 10, 6, 15
Answers
Given the set of data:
5, 4, 16, 21, 10, 6, 15
Let's create a box-and-whisker plot from the given data.
The box and whisker plot has the following properties:
Let's solve for the following:
• Minimum value or lower extreme:
This is the smallest value in the data set.
Here, the minimum value is 4.
• Maximum value or upper extreme:
This is the greatest number in the data set.
Here, the greatest number is 21.
• Median:
This is the middle value after arranging the data in ascending order(from lowest to greatest).
Arranging in ascending order, we have:
4, 5, 6, 10, 15, 16, 21
The middle number above is = 10
Therefore the median is 10.
• Lower quartile:
The lower quartile is the median of the lower half of the data.
To find the lower quartile, let's list the lower half of data first.
Lower half:
4, 5, 6
The median of the lower half of the data is 5.
Therefore, the lower quartile is 5.
• Upper quartile:
The upper quartile is the median of the upper half of the data set.
Upper half of the data set:
15, 16, 21
The median is 16.
The upper quartile is 16.
Therefore the box and whisker plot created from the given data set is:

AMAn art teacher has 9 3/5 gallons of paint to pour into containers. If each container holds3/5 gallon, how many containers can they fill?Answer type: Mixed numberSubmit Answerattempt 1 out of
Answers
So they can fill 16 containers.
1) If an art Teacher has
9 3/5 gallons
Each container holds
3/5 gallons
2) Firstly, let's turn that mixed number into an improper fraction
9 3/5 = (5 x 9+3) /5 = 48/5
Given that each container holds 3/5, then let's divide
48/5 ÷ 3/5 = 48/5 x 5/3 =16
If we hadn't turned
9 3/5 ÷ 3/5 = 16
3) So they can fill 16 containers.

Explanation:
Given that it rained on Monday, Tuesday, Thursday, and Friday, the actual probability of rain is 4 out of 7 days.

Linear function gis shown in the graph. Write the slope-Intercept form of the equation representing this function.
Answers
To find the equation of the line in slope intercept form the first step is to find the slope of the given line:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]In this formula, m is the slope of the function, y2 and y1 are the y coordinates of 2 points on the line, and x2 and x1 are the x coordinates of the same 2 points, for example, they can be (-1,3) and (0,1):
[tex]m=\frac{1-3}{0-(-1)}=-\frac{2}{1}=-2[/tex]The slope of the line is -2.
Now, we can use the y intercept of the graph of g, which is 1.
The slope intercept form of the equation follows the following general structure:
[tex]y=mx+b[/tex]Where m is the slope of the line and b is the y intercept. Use the known values to replace them on the equation. The intercept form of the equation is:
[tex]y=-2x+1[/tex]Please help me with this timed practice problem.The first step have different options: substract, distribute, divide, add.
Answers
From the starting equation to the first step we can see that the only change was made on the left side of the equation.
We can see that the distributive property of multiplication is being applied to the parenthesis.
So, the "-2"is being distributed to the 5x and the 8.
So, the correct options in step 1 is distribute.
In step 2, we can see that the 6x on the left side are not there anymore and the -10x on the left turned into -16x. That is, we substracted 6x from both sides. Thus, the correct option on Step 2 is substract.
In Step 3, the -16 is not on the left side anymore and the 30 from the right side is in place of the 14. So, we added 16 to both sides in this step, and the correct alternative is add.
Now, on Step 4 we had -16x that turned into x and a denominator of -16 appeared on the right side, so we have divided both sides by -16. The correct alternative on Step 4 is divide.

Answers
For the interest calculation we shall apply the simple interest formula which is;
[tex]\begin{gathered} I=P\times R\times T \\ \text{Where;} \\ P=\text{Initial amount borrowed} \\ R=\text{rate of interest (expressed as decimal)} \\ T=\text{Time in years} \end{gathered}[/tex]The initial amount is $21890, the rate is 14% (that is 0.14) and the time is 164/365 of a year.
Therefore, the interest calculated would be;
[tex]\begin{gathered} I=P\times R\times T \\ I=21890\times0.14\times\frac{164}{365} \\ I=3064.6\times\frac{164}{365} \\ I=1376.9709589 \\ I\approx1376.9\text{ (rounded to the nearest cent)} \end{gathered}[/tex]The interest payable at the end of 164 days is $1,376.90 (rounded to the nearest cent).

Determine the point on the graph of the unit circle that corresponds to pi. Then find cos pi and sin pi, and state which functions are undefined for pi.
Answers
The entire unit circle measures 2pi, then, pi corresponds to the half of the unit circle. It is located at the point (-1,0).
The cosine of pi is equal to the x-coordinate, and the sin of pi is equal to the y-coordinate of the point pi.
Since it is located at (-1,0) thus the cos(pi)=-1 and sin(pi)=0.
The functions that are undefined for pi are those which have sin(pi) as denominator, let's check:

The perimeter is given by the following relationship:
[tex]\text{Perimeter}=2\cdot(\text{length}+\text{width)}[/tex]But i don't know the width, so i can find it by isolating from the area formula as follows:
[tex]\text{Area}=\text{length}\cdot\text{width}[/tex]Isolating the width:

Twice a number, decreased by 4, is at least 12. Which of the following is a solution?8576
Answers
Answer:

Explanation:
Let the number = n
Twice the number decreased by 4:
[tex]2n-4[/tex]The phrase 'at least' means the expression above can either be equal to or greater than 12.
Thus, the given statement as inequality is:
[tex]2n-4\geq12[/tex]We then solve the inequality for n.
[tex]\begin{gathered} \text{ Add 4 to both sides} \\ 2n-4+4\geq12+4 \\ 2n\geq16 \\ \text{ Divide both sides by 2} \\ \frac{2n}{2}\geq\frac{16}{2} \\ n\geq8 \\ \implies n=(8,9,10,\cdots) \end{gathered}[/tex]The number that is a solution is 8.
