To solve this problem, we have to build two equations with the given information. Using x and y to represent the two numbers:
• Equation 1
[tex]x\times y=592[/tex]• Equation 2
[tex]x+y=53[/tex]Now that we have to equations, we have to isolate one variable from one equation and replace it in the other.
[tex]x=53-y[/tex]Then, we will replace this value of x in Equation 1:
[tex](53-y)\cdot y=592[/tex]Solving for y we get:
[tex]53y-y^2=592[/tex][tex]-y^2+53y-592=0[/tex]As we got this expression, we will have to use the General Quadratic Formula. With the help of a calculator, we get both values:
[tex]y_1=16[/tex][tex]y_2=37[/tex]Finally, we have to replace these values in Equation 1 to evaluate which meets the condition:
[tex]x_1=\frac{592}{y_1}[/tex][tex]x_1=\frac{592}{16}=37[/tex][tex]x_2=\frac{592}{y_2}[/tex][tex]x_2=\frac{592}{37_{}}=16[/tex]We have to evaluate the values in each equation:
[tex]\begin{gathered} 37+16=53 \\ 53=53 \end{gathered}[/tex][tex]37\cdot16=592[/tex]The first numbers meet the condition.

give the following five-number summary, find the interquartile range. 29, 37, 50, 66, 94
we have the data set
29, 37, 50, 66, 94
step 1
Order the data from least to greatest
so
29, 37, 50, 66, 94
step 2
Find the median
29, 37, 50, 66, 94
the median is 50
step 3
Calculate the median of both the lower and upper half of the data
29, 37, 50, 66, 94
the lower half ------> (29+37)/2=33
upper half -------> (66+94)/2=80
step 4
The IQR is the difference between the upper and lower medians
so
80-33=47
the answer is 47A composite figure is shown. 10 ft А 6 ft - 10 ft तो 12 ft B C 12 ft 4 ft Determine whether each statement about the composite figure is correct. Choose True or False for each statement. a. The area of region B is the same as the area of region C. True False b. The area of region A is double the area of region C. True False C. The area of the composite figure is 180 square feet. True False True False d. The sum of the areas of regions B and C is less than the area of region A.
ANSWERS
a. True
b. False
c. True
d. False
EXPLANATION
a. Regions B and C are both rectangles with the same side lengths. Therefore, they are congruent rectangles, so the areas must be the same.
b. For this item we have to find the areas of region A and C.
Region A is a trapezoid. The area is:
[tex]A_A=\frac{(10+18)}{2}\times6=84ft^2[/tex]The area of region C is:
[tex]A_C=12ft\times4ft=48ft^2[/tex]Two times the area of region C is 96ft², so this statement is false.
c. In the previous item we found the area of regions A and C. From item a we know that the area of region C is the same area of region B. The area of the figure is:
[tex]A=A_A+A_B+A_C=84+48+48=180ft^2[/tex]This statement is true.
d. Since regions B and C have the same area, saying 'the sum of the areas of regions B and C' is the same as saying 'double the area of region C'. From item b, we know that the sum of areas B and C is 96ft², and area A is 84ft².
Area A is less than the sum of areas B and C. Therefore this statement is false.

[tex]-4-2y=-x[/tex][tex]x-2y-4=0[/tex][tex]x-2y=4[/tex]The standard form is
[tex]x-2y=4[/tex]ANSWER
What is the equation of the circle whose diameter is the segment with endpoints (4,3) and (20,-9).
The standard equation of a circle is expressed according to the equation
[tex](x-a)^2+(y-b)^2=r^2[/tex]where;
(a, b) is the coordinate of the centre of the circle
r is the radius of the circle;
Get the diameter of the circle;
[tex]\begin{gathered} D=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \\ D=\sqrt[]{(20-4)^2+(-9-3)^2} \\ D=\sqrt[]{16^2+(-12)^2} \\ D=\sqrt[]{256+144} \\ D=\sqrt[]{400} \\ D=20\text{units} \end{gathered}[/tex]For the radius of the circle;
[tex]\begin{gathered} r=\frac{D}{2} \\ r=\frac{20}{2} \\ r=10\text{units} \end{gathered}[/tex]Get the centre of the circle. Note that the centre will be the midpoint of the given endpoints as shown;
[tex]\begin{gathered} (a,b)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ (a,b)=(\frac{4+20}{2},\frac{3-9}{2}) \\ (a,b)=(\frac{24}{2},-\frac{6}{2}) \\ (a,b)=(12,-3) \end{gathered}[/tex]Substitute the centre (12, 3) and the radius 10 units into the equation of the circle above to have:
[tex]\begin{gathered} (x-12)^2+(y-(-3))^2=10^2 \\ (x-12)^2+(y+3)=100 \end{gathered}[/tex]This gives the equation of the circle whose diameter is the segment with endpoints (4,3) and (20,-9).

1. The cheapest movie theatre is Fantastic Flicks.
2. The most expensive movie theatre is Movie Mania.
3. The slopes for the ticket prices for Movie Mania, Perfect Picture, The Big Screen, and Fantastic Flicks are 13.5, 13.1, 12.9, and 12.75.
4. The equation to represent all the four options is (y - 13.5x)*(y - 13.1x)*(y - 12.9x)*(y - 12.75x) = 0.
We have four movie theaters. The names of the movie theatres are Movie Mania, Perfect Picture, The Big Screen, and Fantastic Flicks. We need to calculate the slopes for each option. Let the slopes for Movie Mania, Perfect Picture, The Big Screen, and Fantastic Flicks be m1, m2, m3, and m4, respectively.
m1 = 27/2 = 13.5
m2 = 65.5/5 = 13.1
m3 = 12.9
m4 = 153/12 = 12.75
The equations for the price of tickets for each theatre are given below.
E1 : y = 13.5x
E2 : y = 13.1x
E3 : y = 12.9x
E4 : y = 12.75x
The theatre with the minimum slope is the cheapest. The theatre with the maximum slope is the most expensive.
The equation to represent all four options is the product of all the other equations.
(y - 13.5x)*(y - 13.1x)*(y - 12.9x)*(y - 12.75x) = 0

A certain virus infects one in every 300 people. A test used to detect the virus in a person is positive 80% of the time if the person has the virus and 10% of the time if the person does not have the virus. (This 10% result is called a false positive.) Let A be the event "the person is infected" and B be the event "the person tests positive". DRAW A TREE DIAGRAM IN YOUR NOTES AND USE IT TO HELP YOU SOLVE THIS PROBLEM. Find the probability that a person has the virus given that they have tested positive; i.e. find P(AIB). Give your answer as a decimal number and include at least 3 or more non-zero digits. P(AIB)=
In the tree, the first branch will be person has virus or person doesn't have the virus.
P(virus) = 1/300
P(not virus) = 299/300
Now,
Then we branch out from each option. These branches would be positive or negative.
If they have virus:
P(positive) = 0.8
P(negative) = 0.2
If don't have virus:
P(positive) = 0.1
P(negative) = 0.9
Now, solving the question of probability that a person has the virus given that they have tested positive:
We find:
P(A|B)
P(has virus | positive test) = P(positive and has virus) / P(positive test)
P(positive and has virus) = 4/5 * 1/300 = 4/1500
P(positive test) = 1/300 * 4/5 + 1/10 * 299/300
= (4/1500)+(299/3000)
=(8/3000) + (299/3000) = 307/3000
= 0.10233
So,
P(positive and has virus) / P(positive test) = 4/1500 divided by 299/3000 = 0.02675

This is basic parabola of the form:
[tex]y=ax^2-b[/tex]So, this one is shifted 1 units down.
The vertex is at (0, -1).
To take 2 points to the left of vertex, we find coordinates for x = -2 and x = -4.
To take 2 points to the right of vertex, we find coordinates for x = 2 and x = 4.

In this problem, we are trying to choose between using a permutation and a combination.
The main difference between the two is the order.
In a combination, order doesn't matter, but it does matter in a permutation. Since the coach is choosing people based on how they performed, this will be a permutation.
For the first box on your screen, you should drag and drop the "P" variable for permutation.
Next, we need to apply the permutation formula:
[tex]_nP_r=\frac{n!}{(n-r)!}[/tex]I'm assuming there are a total of 14 players on the team? So we will let
[tex]\begin{gathered} n=14 \\ r=3 \end{gathered}[/tex]Where n represents the total number of players, and r represents the number of people being chosen based on performance. Then we have:
[tex]\frac{14!}{(14-3)!}=\frac{14!}{11!}[/tex]You can drag the 14! to the numerator and the 11! to the denominator.
Finally, we need to simplify to get the final answer. We can always use a calculator, but I'll show the steps for simplifying here:
[tex]\begin{gathered} \text{ Rewrite}14! \\ \frac{14\cdot13\cdot12\cdot11!}{11!} \end{gathered}[/tex][tex]\begin{gathered} \text{ Cancel the }11! \\ \\ \frac{14\cdot13\cdot12\cdot\cancel{11!}}{\cancel{11!}} \end{gathered}[/tex]Multiply the remaining values:
[tex]14\cdot13\cdot12=2184[/tex]The coach has 2184 ways to choose a player.

Given h(x) = 5x – 3 and m(x)= -2x^2 what (h o m)(-1)=
Let's begin by listing out the information given to us:
[tex]\begin{gathered} h\mleft(x\mright)=5x-3 \\ m\mleft(x\mright)=-2x^2 \\ \mleft(h^om\mright)\mleft(x\mright)=5(-2x^2)-3 \\ (h^om)(1)=-10x^2-3=-10(-1^3)-3 \\ (h^om)(1)=10-3=7 \\ (h^om)(1)=7 \end{gathered}[/tex]Suppose sin(A) 2/5 Use the trig identity sin(A) + cos(A) = 1 and the trig identity tan(A)= sin(A)/cos(A) to find can(A) in quadrant I. Round to ten thousandth.
Trigonometric identity is tanθ ≅ 0.4364
[tex]$\sin A=\frac{2}{5}$[/tex]
[tex]$\cos ^2 A=1-\sin ^2 A=\frac{21}{25}$[/tex]
[tex]$\cos A=\frac{\sqrt{21}}{5}$[/tex]
[tex]$\tan A=\frac{\sin A}{\cos A}=\frac{\left(\frac{2}{5}\right)}{\left(\frac{\sqrt{21}}{5}\right)}=\frac{2}{\sqrt{21}} \cong 0.4364$[/tex]
Sine, cosine, tangent, cosecant, secant, and cotangent are the functions. All of these trigonometric ratios are defined using the sides of a right triangle, specifically the adjacent, opposite, and hypotenuse sides.
The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan ( − θ ) = − tan θ tan ( − θ ) = − tan θ cot ( − θ ) = − cot θ cot ( − θ ) = − cot θ sin ( − θ ) = − sin θ sin ( − θ ) = − sin θ csc ( − θ ) = − csc θ csc ( − θ ) = − csc θ
