Answer:
Letter B. trust me my answer is correct:)
Step-by-step explanation:
hope it helps
Increasing the sample size by a factor of 4 or multiplying
it by 4 is equal to increasing the standard error by 1/2. Therefore, the
interval will be half as varied. This also works almost for population
averages as lengthy as the multiplier from the t-curve doesn't modify much when
increasing the sample size.
4:3
x:39
We need to find what 3 was multiplied by to get 39:
39/3 = 13.
Now multiply 4 by this number
4*13 = 52
Hope this helped!
Answer:
compressed it by 3 in the x direction
it stretched it by 2 in the y direction
Step-by-step explanation:
f(x) = |x|
then it became
g(x) = |3x| so it compressed it by 3 in the x direction
h(x) = 2 |3x| so it stretched it by 2 in the y direction
