3 more means adding 3
The product of 5 and a number is 5n because you're multiplying a number and 5.

Dane is investing $150,000 for 30 years at an annually compounded rate of 5.5%. What is the difference between his ending accoun

navik [9.2K]

Total = Principal × ( 1 + Rate )^years
Total = 150,000 * (1.055) ^ 30
Total = 150,000 * 4.9839512884
Total = 747,592.69

Total = 150,000 * (1.065) ^ 30
Total = 150,000 * 6.614366163 
Total = 992,154.92

Difference = 992,154.92 -747,592.69 =

Answer:

xbar=14.3421

s=18.7920

Step-by-step explanation:

sample mean

xbar = ∑x/n = (0.20 + 0.73 + 0.99 +1.29 + 2.84 + 3.34 + 4.07 + 4.69 + 4.86 + 6.53 + 7.45 + 8.07 + 8.21 + 12.39 + 31.67 + 32.53 + 33.92 + 36.00 +72.72)/19=14.3421

where n stands for the size of the sample

sample deviation

s= $\sqrt{}$ (∑ $(x_i - x bar )^2$ /(n-1)) = $\sqrt{}$ (∑ $x_i^2$ - $n*xbar^2$ )/(n-1)) = $\sqrt{}$ (0.20^2 + 0.73^2 + 0.99^2 +1.29^2 + 2.84^2 + 3.34^2 + 4.07^2 + 4.69^2 + 4.86^2 + 6.53^2 + 7.45^2 + 8.07^2 + 8.21^2 + 12.39^2 + 31.67 ^2+ 32.53^2 + 33.92^2 + 36.00^2 +72.72^2-19*14.3421^2)/(19-1)) = 18.7920
