Using a savings amount of $450, assume you deposited the total amount

ankoles [38]

Answer:

Step-by-step explanation:

Using the formula for calculating the simple interest to get the rate of return;

Simple Interest = Principal * Rate * Time/100

Given Principal = $450,

Time (in years) = 1 year

Simple interest = $32.75

Rate (in %) =?

Substituting the given values in the given formula to get the rate;

32.75 = 450*1*R/100

450R = 3275

R = 3,275/450

R = 7.3%

The rate of return is 7.3%

What is the standard deviation of the following data set?

tia_tia [17]

Answer:

D. 14.32

Step-by-step explanation:

The formula for standard deviation is:

$SD = \sqrt{\frac{\sum | x-\mu|^2}{N}}$

The mean μ is 33.

The (x minus μ) squared are 361, 49, 49, 361 respectively.

So that the SD = $\sqrt{\frac{820}{4}} \approx 14.31782...$
