Answer:
m = 7
Step-by-step explanation:
2m + -4 = 10
Reorder the terms:
-4 + 2m = 10
Solving
-4 + 2m = 10
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2m = 10 + 4
Combine like terms: -4 + 4 = 0
0 + 2m = 10 + 4
2m = 10 + 4
Combine like terms: 10 + 4 = 14
2m = 14
Divide each side by '2'.
m = 7
Simplifying
m = 7
The probability is 0.69.
We find the z-scores that correspond with each end of the range we're looking for. To find a z-score, we use the formula:
Using a z-table (http://www.z-table.com) we see that the area under the curve left of the score 350 would be 0.228. The area under the curve left of the score 400 would be 0.918. To find just the range between 350 and 400, we subtract the area left of 350 from the area left of 400; this will give us just from 350 to 400:
0.918-0.228 = 0.69.

The midpoint of AB where A(a) and B(b): (a + b)/2
(-9 + 6)/2 = -3/2 = -1.5
Answer: B. -1.5
Rectangle Z is not a scale drawing of Rectangle Y.
This is because there is no equal sides where it makes up the constant proportionality.
6/4 (= 3/2) in the left and right sides of the rectangle (Y/Z)
4/3 in the top and bottom sides of the rectangle (Y/Z)
As you can see 3/2 is not equal to 4/3 of scaling, so therefore it is not a scaling.
