Answer:
Δn=3
Step-by-step explanation:
Remember, if we need to divide the interval (a,b) in n equal subinterval, then we need divide the distance (d) between the endpoints of the interval and divide it by n. Then the width Δn of each subinterval is d/n.
We have the interval [-5,7]. The distance between the endpoints of the interval is
.
Now, we divide d by 4 and obtain
Then, Δn=3.
Now, to find the endpoints of each sub-interval, we add 3 from the left end of the interval.
So,
Answer:
174 inches squared
Step-by-step explanation:
First, we have to remember what the area of a triangle is:
Since there are 4 of the same triangle, multiply the area of one triangle by 4:
The minimum sample size required for a test with a confidence interval of 
with a z-score of 
and margin of error of E and a population proportion of p is given by:
Given p = 34% = 0.34, E = 0.027,
Therefore,
Given p = 34% = 0.34, E = 0.027,
Therefore,
