Y increases by 8 as x increases by 2 so the relationship is linear with slope 4. That is y=4x+c and 7=-20+c, so c=27.
The relationship seems to be y=4x+27. The only point to fit this equation is (1,31), Answer 3
15 because 3 is one serving and multiplied by 5 servings is 25
1 hour is equivalent to 60 minutes
3/4 hours is - 60 minutes x 3/4 = 45 minutes
3 hours are equivalent to 60 minutes/hr x 3 hr = 180 minutes
it takes Cindy 45 minutes to complete a puzzle
so it takes her 45 minutes for - 1 puzzle
then in 180 minutes she can make - 1/45 x 180 = 4 puzzles
in 3 hours she can complete 4 puzzles
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)
