Answer:

a) 99.7%

b) 68%

Explanation:

\mu = Mean = 168 cm

\sigma = Standard deviation = 6 cm

a. 150 cm and 186 cm

168-6\times 3=150

168+6\times 3=186

They vary by 3 standard deviations. So, 99.7% of men are between 150 and 186 cm

b. 162 cm and 174 cm

168-6\times 1=162

168+6\times 1=174

They vary by 1 standard deviations. So, 68% of men are between 162 and 174 cm

My amount of money is _ 131,040
Zina [86]

EMI = $658.69

<u>Explanation:</u>

Amount of money, Principal P = $131,040

Time, n = 15 year , n = 180 months

Rate of interest, R = 6% per annum = 0.5% per month

Amount per month, EMI = ?

We know,

EMI = [ P X R X (1 + R)ⁿ] / [(1 + R)ⁿ⁻¹]

EMI = [131040 X 0.005 X (1+0.005)¹⁸⁰ ] / [(1+0.005)¹⁸⁰⁻¹

EMI = [655.2 X 2.454] / 2.441

EMI = $658.69

Therefore, EMI = $658.69
