Answer:

Explanation on ratio and rates.

Step-by-step explanation:

So rates are when you compare two things. For example let's say there are 12 boys and 10 girls. The ratio would be 12:10 or 6:5. Rates is also comparing two things but in fraction format. For example if you drive 30 miles in 3 hours the rate would be 30/3. 10 miles per hour is a unit rate since it is 1 hour, 10/1. I hope this helps you, have a good day.

A fire insurance company has high-risk, medium-risk, and low-risk clients, that have, respectively, probabilities 0.02, 0.01, an
KIM [24]

Answer:

Probability that the claim came from a high-risk client = claim from a high-risk client / claim from all clients

= 0.002 / (0.002 + 0.002 + 0.00175)

= 0.002 / 0.00575‬

= 0.3478

= 0.35

Step-by-step explanation:

Claims filed by each group of clients is gotten by multiplying the probabilities of occurrence by proportions of the number of client in the category

Claims filed by high-risk clients = 0.02 * 0.10 = 0.002‬

Claims filed by medium-risk clients = 0.01 * 0.20 = 0.002‬

Claims filed by low-risk clients = 0.0025 * 0.70 = 0.00175‬

Which expressions are equivalent to 3(4h + 2k)?
faltersainse [42]

Answer:

A

Step-by-step explanation:

If we distribute the 3 to the equation in the parenthesis, we end up with this

12h + 6k

Now, let's do the same thing for the other two equations

3(2k + 4h) = 6k + 12h

You can rearrange this equation to look like 12h+ 6k, making it the exact same as 3(4h + 2k).

So A is equivalent

How about B?

3(4h + 2h) = 12h + 6h = 18h

18h does not equal 12h + 6k, so B is not equivalent
