Here is the answer to the given question above. Given that there are a total of 18 students and 5/9 of the students have pets, let us divide 18 by 9 to see how many students have pets. So the answer would be 2. Since it is 5 out of 9, we multiply 2 by 5 and we get 10. Therefore, the answer is 10 students. Hope this answer helps.

Igoryamba

Answer:

Step-by-step explanation:

a) Because you are only receiving $1500 and in exchange you would have to cover for this accident damage in the next year, which could be up to hundred of thousands of dollar. Sure there's a chance the your neighbor might drive safely, but the odds are far more in his favor than yours.

b) The insurance company collect payments from hundred of thousands buyers, making their cash flow up to tens of million dollar. Sure the expected value of accidents might be high but as a company they surely have capital to cover a handful of cases, if their calculation done right.

or,

d + q = 50

10d + 25q = 1025

What is the recursive rule for the sequence?
love history [14]

Answer : option d

4.4, 5.8, 7.2, 8.6, 10, …

First we find the common difference between two terms

5.8 - 4.4 = 1.4

7.2 - 5.8 = 1.4

8.6 - 7.2 = 1.4

10 - 8.6 = 1.4

So common difference is 1.4

To find recursive rule, we add the difference with previous term

Recursive rule is a_n = a_{n-1} + d

a1 is the first term so a1= 4.4

d is the difference = 1.4

So recursive rule is

a_n = a_{n-1} + 1.4, where a1 = 4.4

A savings account is started with an initial deposit of $700. The account earns 1.5% interest compounded
marusya05 [52]

Answer:

  (a)  A = 700×1.015^t

  (b)  36.2 years

Step-by-step explanation:

(a) Each year, the account value is multiplied by (1 + 1.5%) = 1.015. Repeated multiplication is signified using an exponent. In t years, when the account has been multiplied by 1.015 t times, the account value will be ...

  A = $700×1.015^t

__

(b) You want to find t when A=$1200. Logarithms are involved.

  1200 = 700×1.015^t . . . . use 1200 for A

  1200/700 = 1.015^t . . . . . divide by 700

  log(12/7) = t×log(1.015) . . . . . take logarithms

  log(12/7)/log(1.015) = t ≈ 36.2 . . . . divide by the coefficient of t

It will take about 36.2 years for the account balance to reach $1200.
