Answer:

119.2

Step-by-step explanation:

Given the following :

Mean (m) = 100 years

Standard deviation (sd) = 15 years

closest to the age of a Galápagos Islands giant tortoise at the 90th percentile of the

distribution?

Obtain the Zscore for 90th percentile (0.90) on the z table = 1.28

Zscore = (X - mean) / standard deviation

1.28 = (X - 100) / 15

1.28 × 15 = X - 100

19.2 = X - 100

19.2 + 100 = X

X = 119.2

A couple deposits $20,000 into an account earning 5% annual interest for 30 years. Calculate the future value of the investment
makvit [3.9K]

The future value of the investment if the interest is compounded monthly is $89,354.89.

<h3>What is the future value of the investment?</h3>

Given that;

  • Principal P = $20,000
  • Annual interest rate r = 5% = 5/100 = 0.05
  • Time t = 30 years
  • Compound monthly = 12
  • Future value = A = ?

Using the compound interest formula;

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

We plug in our values.

A = 20000( 1 + 0.05/12 )^(12 × 30)

A = 20000( 1 + 0.0041666666666667)^(360)

A = 20000( 1.0041666666666667)^(360)

A = 20000( 4.46774965 )

A = 89354.89

Therefore, the future value of the investment if the interest is compounded monthly is $89,354.89.
