Answer:
A
Step-by-step explanation:
The formula y = mx + b is a Linear function
8m(4+7p) is one factorization because I took what is found in both numbers (both 32 and 56 can be divided by 8, and the letter m is in both values) and left what isn't common about the numbers in parenthesis (32/8=4; 56/8=7 and mp-m=p). I hope this makes some sense.
It is C) 2.55 because i was taught that you can subtract the negative from the positive. 5.35-2.8=2.55 and it is positive
The answer you are looking for is B
<span>Answer: Skewed to right with mean 0 and S.D. 1
Explanation: Let's assume the z-scores as a linear transformation.
then z=(x-mean)/S.D. = (x-30)/15
z(mean) = (30-30)/15= 0
z(sigma) = 15/15 = 1
