The ages of dogs at an animal shelter are normally distributed with a mean of 3.9 years and a standard deviation of 1.2 years.

Aleks [24]

Answer:

<u>The correct answer is A. 1.86 years</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Mean of the dogs at an animal shelter = 3.9 years

Standard deviation = 1.2 years

2. What is the age of a dog at the shelter with a z-score of −1.7 ?

Let's recall that z-score in a normal distribution, positive or negative, is the number of times of the standard deviation a certain element is from the mean. If the element is below the mean, then the z-score is negative and if it's above the mean, then the z-score is positive.

Therefore, a z-score of - 1.7 for the ages of dogs is:

-1.7 * 1.2 = -2.04

Now, we calculate the value using the mean, this way:

3.9 + -2.04 = 3.9 - 2.04 = 1.86

<u>The correct answer is A. 1.86 years</u>

a jar contains ten black buttons and six brown buttons. If nine buttons are picked at random, what is the probability that exact

Anuta_ua [19.1K]

Answer:

33.04% probability that exactly five of them are black

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the buttons are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

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

Desired outcomes:

Five black buttons, from a set of 10

Four brown buttons, from a set of 6.

$D = C_{10,5}*C_{6,4} = \frac{10!}{5!(10-5)!}*\frac{6!}{4!(6-4)!} = 3780$

Total outcomes:

Nine buttons, from a set of 16.

$T = C_{16,9} = \frac{16!}{9!(16-9)!} = 11440$

Probability:

$p = \frac{D}{T} = \frac{3780}{11440} = 0.3304$

33.04% probability that exactly five of them are black
