Size 2 will be the better deal because if you divide all the size 1,2,3 by the cost and the loads the cheapest one per load is size 2 @23 cents each load
Complete Question:
41% of U.S. adults have very little confidence in newspapers. You randomly select 10 U.S. adults. Find the probability that the number of U.S. adults who have very little confidence in newspapers is (a) exactly five, (b) at least six, and (c) less than four.
Answer:
a) P(exactly 5) = 0.209
b) P(at least six) = 0.183
c) P(less than four) = 0.358
Step-by-step explanation:
Sample size, n = 10
Proportion of adults that have very little confidence in newspapers, p = 41% p = 0.41
q = 1 - 0.41 = 0.59
This is a binomial distribution question:
a) P(exactly 5)
b) P(at least six)
c) P(less than four)
Answer:
2.9%
Step-by-step explanation:
The problem says the stations are 260 feet apart. Assuming that this is the horizontal distance between them, then the grade is:
7.5 / 260 × 100% = 2.9%
This is less than the maximum of 3.5%, so it meets the standards.
