Suppose we have a large population with mean μ = 78 and standard deviation σ = 7.2. let’s say we randomly sample 100 values from this population and compute the mean, then repeat this sampling process 10,000 times and record all the means we get. which of the following is the best approximation for the standard deviation of our 10,000 sample means? a. 9.2

b. 90

c. 96

iu

step-by-step explanation:

because 1.2 isnt half of 6 duh

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
