Please help me with this anyone I beg
Ilia_Sergeevich [38]

Answer:

A)336

B) In how many ways can you arrange 8 people in 3 different chairs?

C) 21

D) You want to buy 3 cartoon books from a book store that has 7 cartoon books. In how many ways can you select?

Step-by-step explanation:

A) P(n, r) = P(8, 3)

Formula for permutation is;

P(n, r) = n!/(n - r)!

P(8, 3) = 8!/(8 - 3)!

P(8, 3) = (8 × 7 × 6 × 5!)/5!

5! will cancel out to give;

P(8, 3) = (8 × 7 × 6)

P(8, 3) = 336

B) In how many ways can you arrange 8 people in 3 different chairs?

C) C(n, r) = C(7, 2)

Formula for combination is;

C(7, 2) = n!/(n - r)!r!

Thus;

C(7, 2) = 7!/(7 - 2)!2!

C(7, 2) = (7 × 6 × 5!)/(5! × 2 × 1)

5! will cancel out to give;

C(7, 2) = 7 × 6/2

C(7, 2) = 21

D) You want to buy 3 cartoon books from a book store that has 7 cartoon books. In how many ways can you select?

Scientists want to estimate the mean weight of mice after they have been fed a special diet. From previous studies, it is known
Assoli18 [71]

Answer: n = 267

Step-by-step explanation: <u>Margin</u> <u>of</u> <u>Error</u> shows the percentage that will differ the result you get from the real population value or, in other words, is the range of values in a confidence interval.

It can be calculated as

margin of error = z\frac{s}{\sqrt{n} }

in which

z is z-score related to the confidence interval, which is this case is 1.96;

s is standard deviation;

n is the number in a sample;

So, the number of mice must be:

margin of error = z\frac{s}{\sqrt{n} }

0.6=1.96\frac{5}{\sqrt{n} }

\sqrt{n}=\frac{1.96*5}{0.6}

\sqrt{n}=16.33

n = 267

<u>For the margin of error with 95% confidence interval be 0.6, it is needed </u><u>267 mice</u><u>.</u>
