Matthew collected data about the ages of the actors in two different community theater groups. He drew a box plot for one of the sets of data and made a table of the other set of data.Ages of Actors is the Southside Players
For the Northside players, the median is 36, the range is 32 and the IQR is 18. For the southside Players : the median is 26, the range is 12 and the IQR is 12.
What is median?The median is regarded as the middle number among a series of sorted numbers that are placed in ascending or descending order.
Note that from the image attached, the northside ages are 22, 25, 28, 29, 29, 36, 36, 41, 49, 49, 54.
The median northside ages therefore is 36
For Range = Highest number - Lowest number
54-22 = 32
IQR = Q₃ - Q₁
Note that first quartile Q1 is said to be the median of the n lowest values and third quartile Q3 is the median of the n highest values.
Lowest value is 22 + 25/2 = 28.5.
Highest value is 49 + 44/ 2= 46.5.
Therefore, IQR = Q₃ - Q₁
46.5 - 28.5 =
IQR = 36
Note, for Southside Players;
If the Ages of Actors is the Southside Players are 20 22 24 26 28 30 32 34.
Then the median is = 26
Range is = 34-22 = 12
IQR = Q₃ - Q₁
Lowest = 20 + 22/ 2 = 21
Highest is 32 + 34 / 2 = 33
33 - 21
IQR = 12
Therefore, for the Northside players, the median is 36, the range is 32 and the IQR is 18. For the southside Players : the median is 26, the range is 12 and the IQR is 12.

Ben spent 1/6 of his money on a burger, fries, and a drink. Then he spent half of the money he had left: $5 on a magazine, $8.25 on a bookmark, and $10.50 on a book. How much money did he have to begin with?
Please answer asap and please explain your answer.
The amount of money Ben had to begin with after spending 1/6 and 1/2 of it is 57 dollars.
How to find the how much money he had with an equation?let
x = amount he had to begin with
He spent 1/6 of his money on a burger, fries, and a drink. Therefore,
amount spent on burger, fries, and a drink = 1 / 6 x
Hence,
amount he had left = x - 1 / 6 x =6x - x /6 = 5 / 6 x
Then he spent half of the money he had left.
1 / 2(5 /6 x) = 5 + 8.25 + 10.50
5 / 12 x = 23.75
cross multiply
5x = 23.75 × 12
5x = 285
divide both sides by 5
x = 285 / 5
x = 57
Therefore, the amount of money he have to begin with is $57.

If triangleABC is a right angle triangle at C.then what is the value of cos(A+B)

As we know that the sum of all three angles of a triangle is 180°.
If ∆ABC is right angled at C
C = 90°

=> [tex]\:\sf{∠A\: +\:∠B\: +\: 90°\:=\:180°}[/tex]

On Friday, Jessica babysat for 3 hours and earned $27. On Saturday, Jessica babysat for 6 hours and earned $54. On Friday, Jessica babysat for 7 hours and earned $63. Write an equation to represent her earnings if x represents hours and y represents earnings
Answer:
y = 9x
Step-by-step explanation:
We can make the x-values represent how many hours Jessica babysat, and the y-values represent how much money she earned each day.
We have these points:
(3, 27)(6, 54)(7, 63)The days of the week she worked do not matter in this problem. We are just trying to find the association between hours worked and money earned.
We can start by finding the slope of the line by using two of the points. I will be using (3, 27) and (6, 54).
The slope formula is [tex]\displaystyle m = \frac{y_2-y_1}{x_2-x_1}[/tex].
Substitute these two points into the formula:
[tex]\displaystyle m = \frac{54-27}{6-3}[/tex] [tex]\displaystyle m = \frac{27}{3}[/tex][tex]m=9[/tex]The slope of the line is m = 9.
Now, we can use the point-slope equation to find the equation of the line that represents Jessica's earnings.
Point-slope equation: [tex]y-y_1=m(x-x_1)[/tex].
Substitute the slope m = 9 and the point (3, 27) into the equation.
[tex]y-(27)=9(x-(3))[/tex] [tex]y-27=9(x-3)[/tex] [tex]y-27=9x-27[/tex][tex]y=9x[/tex]The equation y = 9x represents Jessica's earnings, where x represents hours and y represents earnings.

What is an equation of the line perpendicular to 5x−4y=10 that passes through the point (−1,−6) ?
Answer:
y = -4/5x-34/5
Step-by-step explanation:
1. Put into slope-intercept form: 5x-4y = 10 ⇒ 4y = 5x-10 ⇒ y = 5/4x - 5/2
2. A perpendicular slope is the negative reciprocal of the original slope. ⇒ m = -4/5
3. Make a general solution using the new slope: y = -4/5x + b
4. Plug in the point (-1,-6) and solve for b: -6 = -4/5(-1) + b ⇒ -6-(4/5) = b ⇒
b = -34/5
5. Put b in the general solution to find the particular solution: y = -4/5x-34/5

[C] 75/100
Step-by-step explanation:
Given:
What is 0.75 written as a fraction?
Solution:
0.75 = Decimal
Rewriting the decimal number as a fraction with 1 in the denominator
[tex]0.75=\frac{0.75}1[/tex]
Now, multiply to remove the 2 decimal places. So, you multiply top and bottom by 10² = 100
10² is the same thing as 100 because 10² = 10 × 10 and 10 × 10 = 100
[tex]\frac{0.75}{1}\times\frac{100}{100}=\frac{75}{100}[/tex]
Thus, the answer is [C] 75/100

The value of t at a height of 11 feet is 0.36 sec when the ball is going upwards and 1.39 seconds when the ball is coming downwards.
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers.
It is written in the form of ax²+bx+c.
Given that the height of the ball at time t is given by the function,
[tex]h(t) = 3+ 28t -16t^2[/tex]
where t is in seconds and h is in feet.
Now, the height of the ball is given to be 11 feet, therefore, substituting the value of h in the function as 11,
[tex]h(t) = 3+ 28t -16t^2\\\\11 = 3+ 28t -16t^2\\\\-16t^2 + 28t +3 -11 = 0\\\\-16t^2 + 28t -8 = 0[/tex]
Now, solving the given quadratic equation, we will get,
[tex]x= \dfrac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\t = \dfrac{-(28)\pm \sqrt{(28)^2-4(-16)(-8)}}{2(-16)}\\\\t= 0.36\ or\ 1.39[/tex]
Hence, the value of t at a height of 11 feet is 0.36 sec when the ball is going upwards and 1.39 seconds when the ball is coming downwards.
