Answer:
1 mile = 0.2 hours
Step-by-step explanation:
Given that,
Eddie can travel 20 miles in 4 hours.
We need to find how many hours does it take Eddie to travel 1 mile.
20 mile = 4 hours
1 mile = (4/20) hours
= 0.2 hours
So, to travel 1 mile will take 0.2 hours.
Answer:
2.22
Step-by-step explanation:
Finding the sample size for estimating a population proportion.
The formula is:
n = (z/m)^2 p~(1−p~)
where:
Z is the z value of the confidence level where 95% is equal to 1.96
M is the margin of error where 0.05
And p~ is the estimated value of the proportion where it is 0.50
Solution:
n = (1.96/0.05)^2 (0.5) (1-0.5)
= 1.536.64 (0.5) (0.5)
= 768.32 (0.5)
= 384.16
This is the minimum sample size, therefore we should round it up to 385. The answer is letter c.
