Using proportions, it is found that 7% of the population has blue eyes without blonde hair.

10% of the population has blue eyes. These 10% are composed by:

  • 75% of 4%(have blonde hair).
  • x% of 96%(do not have blonde hair)

Hence, the relation according to the proportion of 10% is:

0.75(0.04) + 0.96x = 0.1

x = \frac{0.1 - 0.75(0.04)}{0.96}

x = 0.0729

Out of the entire population:

0.0729(0.96) = 0.07

7% of the population has blue eyes without blonde hair.

Find the corresponding effective interest rate for 3% per year compounded continuously?
jeyben [28]

Answer:

3.045%.

Step-by-step explanation:

We are asked to find the corresponding effective interest rate for 3% per year compounded continuously.

We will use effective interest formula to solve our given problem.

r=e^i-1, where,

r = Effective interest rate,

e = Mathematical constant,

r = Interest rate in decimal form.

Let us convert given interest rate in decimal form.

3\%=\frac{3}{100}=0.03

Substitute values:

r=e^{0.03}-1

r=1.030454533953517-1

r=0.030454533953517

r\approx 0.03045

Convert into percentage:

0.03045\times 100\%=3.045\%

Therefore, the corresponding interest rate would be 3.045%.
