ANSWER:
INFERENTIAL STATISTICS
STEP-STEP-BY EXPLANATION:
Inferential statistics are mathematical tools for estimating how likely it is that a statistical result based on data from a random sample is representative of the population from which the sample is assumed to have been selected.
It can make inferences from data to more general conditions like
* estimate the degree of confidence that can be placed in generalizations from a sample to the population from which the sample was drawn. (generalize your sample to a larger population)
To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter C.
The slope of that line is “undefined”. The slope of horizontal lines are 0 and the slope of vertical lines are undefined.

(3+4i)*4 = 3*4+4i*4 = 12+16i
The complex number 12+16i is in the form a+bi where a = 12 and b = 16
m = modulus
m = distance from (0,0) to (a,b)
m = sqrt(a^2+b^2)
m = sqrt(12^2+16^2)
m = sqrt(144+256)
m = sqrt(400)
m = 20
Answer: 20
