C) The probability that you pick at least one purple marble is 98%.

<h3><u>Probability</u></h3>

The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.

Now, to answer the questions, the following calculations must be done:

C) 100 - (2/9x9) = X
100 - 2 = X
98 = X

A population is normally distributed with mean 18 and standard deviation 1.7. (a) Find the intervals representing one, two, and

elena55 [62]

Answer:

Interval within 1 standard deviation: (16.3,19.7)

Interval within 2 standard deviation: (14.6, 21.4)

Interval within 3 standard deviation: (12.9, 23.1)

Step-by-step explanation:

We are given the following in the question:

Population mean, $\mu$ = 18

Standard deviation, $\sigma$ = 1.7

We have to find the following intervals:

Interval within 1 standard deviation:

$\mu \pm 1\sigma\\=18 \pm 1.7\\=(16.3, 19.7)$

Interval within 2 standard deviation:

$\mu \pm 2\sigma\\=18 \pm 2(1.7)\\= 18 \pm 3.4\\=(14.6,21.4)$

Interval within 3 standard deviation:

$\mu \pm 3\sigma\\=18 \pm 2(1.7)\\= 18 \pm 5.1\\=(12.9,23.1)$

A circle has a radius of 6 in. Find the area of its inscribed equilateral triangles.

Lina20 [59]

The area of the inscribed triangle = 3(6^2 x sin 120°) = 3(36sin 120°) = 3(31.18) = 93.53 square in.

As a television executive, you have been given 12 shows to choose from to run during your prime time slots each week. If you hav

Oksanka [162]

Answer:

You can create the schedule for the week in 19,958,400 ways.

Step-by-step explanation:

The order in which the shows are scheduled is important, which means that the permutations formula is used to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

How many ways can you create the schedule for the week?

8 shows from a set of 12. So

$P_{(12,8)} = \frac{12!}{(12-8)!} = \frac{12!}{4!} = 19958400$

You can create the schedule for the week in 19,958,400 ways.
