Answer:
B
Step-by-step explanation:
Reflect x-axis means (x,y) becomes (x, -y)
Shrink by 1/3 means f(x) = x becomes f(x) = 1/3x
Up 4 units means f(x) = x becomes f(x)= x + 4
So lets put that together




Answer:
subtraction
Step-by-step explanation:
b= 40 - 5
40- 5 =35
b=40
Answer:
True.
Step-by-step explanation:
If we have for a sample of size n=25 a sample variance of 400, the standard error can be written as:

This way of calculating the standard error is the same used for estimating the standard deviation of the sample means for samples of size n=25.
