Answer:
When y=2/5
(-y)^2= 4/25 and -y^2 = 4/25
When y =-2/5
(--2/5)^2 = 4/25 and -y^2 =4/25
Step-by-step explanation:
Answer:
solution is given below
Step-by-step explanation:
A simple random sample size n = 250 . Of the 250 employed individuals surveyed,42 responded that they did work at home at least once per week.
Construct 99% confidence interval for population
For proportion : 42 / 250 = 1/10 = 0.16
Mean = 2.5 * sqrt [ 0.1 * 0.9 / 250]
= 2.5 * 0.01
= 0.47
Construction of hypothesis:
0.10 - 0.047 < p < 0.10 + 0.047
w = 60 lb (amt. of walnuts needed)
100-w = 40 lb (amt. of peanuts needed)
30miles per second = 30x60 miles per miute = 1800miles per miute
<span>in 5 miutes, 5x1800= 9000miles</span>
