7 * 10^3 = 7 * 1000 = 7000
5 * 10^2 = 5 * 100 = 500

7000/500 = 14

so 7 * 10^3 is 14 times larger then 5 * 10^2 <==

What is the rate on an investment that doubles $5051 in 9 years? Assume interest is compounded quarterly.
Inessa [10]

Answer:

The rate at which the investment gets double is 7.776

Step-by-step explanation:

Given as :

The principal investment = $ 5051

The time period of investment = 9 years

Let The rate of interest = R % compounded quarterly

The Amount gets double

So,  <u>From Compounded method</u>

Amount = Principal ×(1+\dfrac{rate}{4\times 100})^{4\times Time}

Or, 2 × P = P  × ( 1 + \dfrac{\textrm R}{400})^{\textrm 36}

Or, 2 =  ( 1 + \dfrac{\textrm R}{400})^{\textrm 36}

Or, 2^{\frac{1}{36}} = 1 + \dfrac{\textrm R}{400}

or, 1.01944 - 1 =  \dfrac{\textrm R}{400}

or, 0.01944 =  \dfrac{\textrm R}{400}

∴ R = 0.01944 × 400 = 7.776

Hence The rate at which the investment gets double is 7.776   Answer

A basketball player's probability of making a free throw is 0.9. When the player makes two free throws in a row, X is the number
GrogVix [38]

Answer:

0.81

Step-by-step explanation:

P(success) = 0.9

P(failure) = 1 - 0.9 = 0.1

Binomial probability:

P(X=n) = nCr (0.9)^n (0.1)^r

Here, n=2 and r=0:

P(X=2) = ₂C₀ (0.9)² (0.1)⁰

P(X=2) = 0.81
