Can someone help please!! i will give brainliest
olga_2 [115]

Answer:

1. $427.50

2. 50 hours

Step-by-step explanation:

1. First, find your salary at minimum hours, which is $360. Then, take your second equation, plug in 45, and solve using PEMDAS. This will give you $427.50

2. To solve this, you'll need to set it up like so:

495 = 13.5 (x - 40) + 360

Your next step will be to distribute the number outside the parentheses. This will give you:

495 = 13.5x - 540 + 360

Simplify, like so:

495 = 13.5x - 180

Solve.

495 = 13.5x - 180

+180             +180

This will give you:

675 = 13.5x

Divide each side.

675 = 13.5x

------    -------

13.5     13.5

  50 = x

Which statement is the most appropriate comparison of the spreads?
babunello [35]

Answer:

D  The IQR for town A is less than the IQR for town B

Step-by-step explanation:

A small IQR indicates that the points are closer together, while a larger IQR means that the points are scattered and that the plot is skewed in a certain direction. As you can see, town A's plot looks fairly balanced, while town B's plot is skewing to the left. Hope this helps :)
