Answer:
37
Step-by-step explanation:
Given :
Sample size, n = 128
Mean, μ = 18
Standard deviation, σ = 5.4
Number of people who lost atleast 15 pounds :
The Zscore = (x - μ) / (σ)
Zscore = (15 - 18) / 5.4
Zscore = - 3 / 5.4
Zscore = - 0.5555
P(Z < - 0.555) = 0.28945
Number of people who lost atleast 15 pounds :
0.28945 * 128 = 37.0496
= 37 people
The value of n=12

Answer:
16 Miles/Hours
Step-by-step explanation:
Average speed is the total distance covered divided by the total time
In that case we have a distance of 4 miles
Time is 15 minutes and in order to convert from minutes to hours we divide by 60 and it becomes 0.25 hours
So 4/0.25 is 16 Miles/Hours
If correct kindly give me brainliest
This isn't a college question, so you're obviously not in college. I'd say 6th grade. Anyway,

/40 /40
h=19. She gets $19 an hour.
