(Probability with Permutations and Combinations) I’m not sure how to solve this problem/how to get the answer, need help!
tekilochka [14]
The "explanation" for the problem has a typo in it. There are 11 possible ice cream/yogurt flavors to choose from, regardless of whether any are low-fat, so the total number of ways of choosing any 2 from the selection is

11\mathrm C2=\dfrac{11!}{2!(11-2)!}=55


In particular we want to count the number of ways of picking 1 ice cream and 1 yogurt flavor from the low-fat variety. There are 6 total choices that are not low-fat of which we choose 0, 3 choices of low-fat ice cream of which we choose 1, and 2 choices of low-fat yogurt of which we also choose 1. In terms of the binomial coefficient, this is

(6\mathrm C0)\cdot(3\mathrm C1)\cdot(2\mathrm C1)=1\cdot3\cdot2=6

So the probability of getting such a combination is \dfrac6{55}.

Sergeeva-Olga [200]
The formula for continuously compounded interest is:
A=Pe^{rt}
17950=Pe^{0.075\times10}=Pe^{0.75}
P=\frac{17950}{e^{0.75}}=8478.98
The answer is $8478.98

Generate the first 3 terms for the sequence-2n<br> +1.
Cloud [144]

Answer:

- 1, - 3, - 5

Step-by-step explanation:

Substitute n = 1, 2, 3 into the rule, that is

a₁ = - 2(1) + 1 = - 2 + 1 = - 1

a₂ = - 2(2) + 1 = - 4 + 1 = - 3

a₃ = - 2(3) + 1 = - 6 + 1 = - 5

A survey of a random sample of 1,500 young Americans found that 87% had earned their high school diploma. Based on these results
inn [45]

Answer: 0.017

Step-by-step explanation:

The confidence interval for population proportion p is given by :-

\hat{p}-E, where E is the margin of error.

Given : The proportion of the sample of young Americans earned their high school diploma : \hat{p}=0.87

The 95% confidence interval for the proportion of young Americans who have earned their high school diploma is (0.853,0.887) .

i.e.

\hat{p}-E=0.853\ ----------(1)\\\\ \hat{p}+E=0.887----------(2)

Subtract equation (1) from (2) , we get

2E=0.034\\\\\Rightarrow\ E=0.017

Hence, the margin of error for this confidence interval =0.017
