Step-by-step explanation:

it is geometric  

so we will use this equation:

a(n)=a1*(r)^(n-1)

and we have a(1)=75 , r=15/75=3/15=1/3

explicit formula: a(n)=75*(1/3)^(n-1)

hope this helps

7 − 9x − (x + 12) less than or equal to 25?
Nonamiya [84]

Answer:

x  ≥-3

Step-by-step explanation:

7 − 9x − (x + 12) less than or equal to 25

7 − 9x − (x + 12) ≤ 25

Distribute the minus sign

7 − 9x − x - 12 ≤ 25

Combine like terms

− 10x −5 ≤ 25

Add 5 to each side

− 10x −5+5 ≤ 25+5

− 10x ≤ 30

Divide by -10. Remember that this flips the inequality

− 10x/-10 ≥30/-10

x  ≥-3

Suppose that scores on a particular test are normally distributed with a mean of 110 and a standard deviation of 20. What is the
qaws [65]

Answer:

The minimum score needed to be in the top 2% of the scores on the test

is  n = 10,00,000

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Mean of the Population = 110

Standard deviation of the Population = 20

The estimated error = 2% = 0.02

<u><em>Step(ii)</em></u>:-

The estimated error is determined by

                        E = \frac{S.D}{\sqrt{n} }

                       0.02 = \frac{20}{\sqrt{n} }

               ⇒ \sqrt{n} = \frac{20}{0.02} = 1000

Squaring on both sides, we get

                   n = 10,00,000

The minimum score needed to be in the top 2% of the scores on the test

is  n = 10,00,000

Which phrase best describes mortgage collateral?
Anika [276]

Answer:

C. the purchased property that secures the loan

Step-by-step explanation:

Mortgage collateral describe the use of a property e.g house to secure a loan. This collateral is always requested when a large amount of money is involved. The house could be sold if the borrower renege (fail to meet up with) on the due date as regards the agreement after collecting the loan.

Therefore, a mortgage collateral could be referred to as the purchased property that has been used to secure a loan by a borrower.
