Answer:
y = -4x + 5.
Explanation:
Count rise/run to find the slope, find the y-intercept.
The independent variable is the number of sweatshirts sold so it is answer A.
(Money raised is the dependent variable because it depends on the number of sweatshirts sold.)
It is neccesary because you cannot subtract them without having a common denominator so you have to rename 4 1/2
Answer:
The standard error in estimating the mean = (0.1 × standard deviation of the distribution)
Step-by-step explanation:
The standard error of the mean, for a sample, σₓ is related to the standard deviation, σ, through the relation
σₓ = σ/(√n)
n = sample size = 100
σₓ = σ/(√100)
σₓ = (σ/10) = 0.1σ
Hence, the standard error in estimating the mean = (0.1 × standard deviation of the distribution)
