Say we minus the 15 minutes Laura spent reading the magazine from 4:15. You then get 4:00, which is the time she finished reading her book. Now if we go back 40 minutes, we can minus 60 minutes by 40 minutes which gives us 20 minutes, giving us the time of 3:20 pm which is when she arrived. Let me know if you have any more questions!

Records at an insurance company showed that the first 30 customers made an average of 5 claims each through their lifetime. Afte
umka2103 [35]

The average of the 75 customers will be 6.4.

<h3>How to calculate the value?</h3>

The first 30 customers made an average of 5 claims each. The total claims will be:

= (5 × 30) = 150

When 75 more people were assessed, the average was 6. Therefore, the total claims will be:

= (75 + 30) × 6

= 105 × 6

= 630

Therefore, the average of the 75 customers will be:

= (630 - 150)/75

= 480/75

= 6.4

stiv31 [10]
The answer to this, your question is                                                                               h = -16t • 2 + 48t + 6
h = -32t + 48t + 6
h = 16t + 6     HOPE I HELPED IN A WAY!                                                                                                                                             ~Marcey<3

Given the list of numbers, 3, 2, 6, 3, 9, 5, 12, 7, if the pattern continues, what is the sum of the ninth and tenth numbers?
LekaFEV [45]

Answer:

Step-by-step explanation:

Every other one beginning with the first 3 adds 3 to the preceding number that has an odd position.

So the odd positions go up 3 6 9 12

And the next odd position is 15 which is the nineth term.

It's hard to tell what the even ones are doing. It could be anything just about. I'm guessing its a 9. So the tenth term is 9.

The sum of 9 and 15 = 24

If someone gives you a more consistent answer, take it.
