Hi there! So, if $36.40 in interest was in her account after 3.5 years, we can divide both numbers. 36.4/3.5 is 10.4. That's $10.40 in interest per year, with the rate of simple interest being 6.5%. But to make it easier, we can divide 10.40 by 6.5 to find the unit rate. When you divide both number, you get 1.6. 1% of the initial amount is $1.60. Percents are parts of 100. Multiply 1.6 by 100 to get 160. Now, let's divide the interest earned yearly by initial amount to see if it works. 10.4/160 is 0.065 or ^.5% when turned into decimal form. there. Safiya's initial deposit in the bank was $160.

DedPeter [7]

Answer:

$11543.63

Step-by-step explanation:

<u>Plug information into A=P(1+r/n)^nt</u>

13000 = P(1+(.04/2))^(2*3)

13000 = P(1.02)^6

<u>Isolate P</u>

13000/(1.02^6) = P

P = $11543.63

X=6 because
9-6=3

X=3 because
2•3=6

Consider a data set containing the following values: 70 65 71 78 89 68 50 75 The mean of the preceding values is 70.75. The devi

Leokris [45]

Answer:

If this is the sample data, the sample variance is 125.07 and the sample standard deviation is 11.18

If this is a population data, the population variance is 109.44 and the population standard deviation is 10.46

Step-by-step explanation:

We are given the following data-set:

70, 65, 71, 78, 89, 68, 50, 75

Deviations from the mean

–0.75, –5.75 , 0.25, 7.25, 18.25, –2.75, –20.75, 4.2

Sample size, n = 8

Sample:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

Sum of squares of differences =

0.5625 + 33.0625 + 0.0625 + 52.5625 + 333.0625 + 7.5625 + 430.5625 + 18.0625 = 875.5

$s = \sqrt{\dfrac{875.5}{7}} = 11.18$

$\text{ Sample variance} = s^2 = 125.07$

Population:

$\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n}$

where $x_i$ are data points, $\bar{x}$ is the mean and n is the number of observations.

Sum of squares of differences =

0.5625 + 33.0625 + 0.0625 + 52.5625 + 333.0625 + 7.5625 + 430.5625 + 18.0625 = 875.5

$\sigma = \sqrt{\dfrac{875.5}{8}} = 10.46$

$\text{ Population variance} = \sigma^2 = 109.44$
