Answer: a) 39.5%

Step-by-step explanation:

<em>For random selections, we assume that all the dogs have the same probability of being selected.</em>

In this case, the probability will be equal to the number of golden retrievers divided the total number of dogs.

We have 58 golden retrievers, and the total number of dogs is:

31 + 58 +20 + 38 = 147

Then the probability is:

P = 58/147 = 0.395

If we multiply it by 100%, we obtain the percentage form:

0.395*100% = 39.5%

So the correct option is a.

Calculate the ending balance of investing $18,000 at 9% Annual Compound Interest for 20 years.
pychu [463]

Answer: $100,879.39

Step-by-step explanation:

We would apply the formula for determining compound interest which is expressed as

A = P(1+r/n)^nt

Where

A = total amount in the account at the end of t years

r represents the interest rate.

n represents the periodic interval at which it was compounded.

P represents the principal or initial amount deposited

From the information given,

P = 18000

r = 9% = 9/100 = 0.09

n = 1 because it was compounded once in a year.

t = 20 years

Therefore,

A = 18000(1+0.09/1)^1 × 20

A = 18000(1.09)^20

A = $100,879.39

Flip a coin and toss a 1-6 number cube. Probability of: (heads and not a 3)
jeka94
When finding the probability of two things happening, you multiply the probability of each individual thing happening. The chances of heads are 1/2 and the chances of not a 3 are 5/6. 1/2*5/6 = 5/12. The probability of that is 5/12
