The Corectttttt Answerrrrr is C
f(t) = 2(0.4)^t
F(-2) means to replace t with -2:
f(-2) = 2(0.4)^-2
f(-2) = 12.5
Answer: 50 yards by 25 yards
Step-by-step explanation:
rink is also a rectangle
perimeter= 150 yards
length= 2x
width=x
the perimeter of rink is:
p=2(length + width)
150=2(2x + x)
150= 2(3x)
150= 6x
x=150 / 6
x=25
so width is 25 yards and length is twice the width which is 2x
length= 2× 25
length= 50 yards
so the dimension is 50 yards by 25 yards
Answer:
Correct option is: Testing a claim about two population means.
Step-by-step explanation:
In this provided scenario, a researchers wants to determine if corporations require a longer work week for the employees "working full-time".
It is given that for many years "working full-time" was 40 hours per week.
The researchers researcher gathers data on the hours that corporate employees work each week.
It is quite clear that the researcher wants to determine whether the number of hours worked per week must be increased from 40 hours or not.
A test for the difference between two population means would help the researcher to reach the conclusion.
Thus, the correct option is: Testing a claim about two population means.
