Answer: 95% confidence interval would be (26.01,29.39).
Step-by-step explanation:
Since we have given that
n = 50
Mean = 27.7
Standard deviation = 6.12
We need to construct 95% confidence interval for the population.
so, z = 1.96
So, it becomes,

Hence, 95% confidence interval would be (26.01,29.39).
N= a number
2n= twice a number
If it's 43 less, then it would be 2n-43.
2n-43 is the answer.
Hope this helps! :)
Answer:
2
Step-by-step explanation:
(f+g)(x)
f(x)= x-3, g(x)= 2x+8
The slope-intercept form of a line is the following:

In this form,
is the shape and
is the y-intercept. Your line written in this form is

which implies that the slope is 5 and the y-intercept is -2.
The answer is 33.5 or 33minutes and 30 seconds
2/45= 22.5
22.5 +11=33.5
