Answer:

1.5

Step-by-step explanation:

Let's begin by dividing each side by 4.

You get 18/4 or 4.5.

m+3=4.5

Now subtract 3 to each side.

m=1.5

Multiple samples of students were asked four questions, with the sampling variability of their answers to question 4 being the h

iogann1982 [59]

The variability measures the closeness of the individual data provided. So, the most reliable sampling is the one with the lowest variability.

For this case, the question with the lowest sampling variability is question 3. Therefore, we can conclude that the answers to which of the questions are most reliable is question 3.

Step-by-step explanation:

y < 4x +3

y > -2x - 9

-2x -9 < 4x +3

-6x < -12

IN CASES WHERE YOU DIVIDE A NEGATIVE NUMBER,DON'T FORGET TO CHANGE THE SIGN !!!

Your investments took a 7% plunge (drop) then increased by 8%. Are you ahead by 1%? Explain.

Sav [38]

Answer:

If your investment dropped 7% and then increased by 8% you will not be a percent ahead. The reason being is that the increase is a lower amount and the decrease was on a larger amount.

For example, if you have $100 invested. 100*.07=$7, 100-7=$93 remaining. 93*08= $7.44. 93+7.44=100.44 (a .44 increase from the original number). One percent increase from the original number would have $101.

PLEASE HELP!!!

ki77a [65]

Part A:
I have attached the graph of this system of inequalities.

Part B:
Plug in (8,10) into both equations

10 > 3(8) + 10
10 > 24 + 10
10 > 34

This is false!

10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7

This is also false!

So, (8,10) is not included in the solution area for the system.
