ANYBODY WHO ANSWERS THIS WILL GET 60 POINTS. Male and female high school students reported how many hours they worked each week

in summer jobs. The data is represented in the following box plots:
two box plots shown. The top one is labeled Males. Minimum at 0, Q1 at 3, median at 10, Q3 at 15, maximum at 35. The bottom box plot is labeled Females. Minimum at 0, Q1 at 2, median at 6, Q3 at 9, maximum at 14

Identify any values of data that might affect the statistical measures of spread and center.

A)The zero hour mark on both plots prevents the graphs from being balanced.
B)The median is near the center of the IQR for both males and females.
C)There is not enough evidence to see any effects on spread or center.
D)The males have a suspected significant high outlier.

D. The males have a suspected significant high outlier. 

The outlier will make the box plot be uneven and this will affect the spread and the center.

I know isn't A, because if anything that would make it more balanced.
I know it isn't B because this would not affect the spread or the center.
I know it isn't C because the question is not asking you to determine the spread and center, just to see if there is anything that would affect them.

I hope this helps!

Please help!(30pts)(I NEED IT QUICK)Find the inverse of the given function:
bezimeni [28]

y = -(1/2) sqrt(x + 3) Interchange the x and y

x = -(1/2) sqrt(y + 3) multiply through by - 2

-2x = sqrt(y + 3) Square both sides.

(-2x)^2 = (sqrt(y + 3))^2

4x^2 = y + 3 Subtract 3 from both sides.

y = 4x^2 - 3

The usual rule is to interchange the domain and range of the original equation with the inverse. The range of the original equation is 0 => y > -infinity.

If that is the case, then the domain of the inverse is 0<=x. The graph was revised and provided by Mathmate. It is the correct way to represent this function and it's inverse Including the fact that x<=0. That restriction is very important. The line is x = y and the graphs should reflect around that line.

You invested money in two funds. Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you receiv
pishuonlain [190]

Answer: $7800 was invested at 9%

$5900 was invested at 3%

Step-by-step explanation:

Let x represent the amount invested in the fund that paid a dividend of 9%.

Let y represent the amount invested in the fund that paid a dividend of 3%.

Last year, the first fund paid a dividend of 9% and the second a dividend of 3%, and you received a total of $879. This means that

0.09x + 0.03y = 879- - - - - - - - - 1

This year, the first fund paid a 10% dividend and the second only 1%, and you received a total of $839. It means that

0.1x + 0.01y = 839 - - - - - - - - - -2

Multiplying equation 1 by 0.1 and equation 2 by 0.09, it becomes

0.009x + 0.003y = 87.9

0.009x + 0.0009y = 75.51

Subtracting, it becomes

0.0021y = 12.39

y = 12.39/0.0021

y = 5900

Substituting y = 5900 into equation 1, it becomes

0.09x + 0.03 × 5900 = 879

0.09x + 177 = 879

0.09x = 879 - 177

0.09x = 702

x = 702/0.09

x = 7800
