1. The number of customers in a restaurant during the peak hour of each day for a month varied

Gnom [1K]

Step-by-step explanation:

First we must calculate the interquartile range (IQR), using this equation:

$IQR = Q_{3} - Q_{1}$

Based on the information provided we fill in:

$IQR = 58 - 45$

$IQR = 13$

In order to find what the range for the data set is we need to use the Interquartile Rule:

$Q_{1}-1.5$ × $IQR\\$

$Q_{3}+1.5$ × $IQR\\$

$1.5$ × $13 = 19.5$

Now we plugin in:

$45 - 19.5 = 25.5\\$

$58 + 19.5 = 77.5$

Any number below 25.5 is a possible outlier and any number above 77.5 is a possible outlier.

Answer:

Based on the results of the calculations, 25 could be a possible outlier in the data set.

Your deposit $1500 into a savings account that pays 6% interest compounded yearly. How much money is in the account after 10 yea

ehidna [41]

Answer:

$2686.27.

Step-by-step explanation:

The formula for the amount of money after compound interest is

$A=P(1+\frac{r}{n} )^{nt}$

where P is the principal, r is the rate, n is the number of times the interest is compounded per year, and t is the number of years. $1500 is the principal amount of money. 6% in decimal form is 0.06 (divided by 100), so the rate is 0.06. The interest is compounded once per year, so n = 1. And it's after 10 years, so t = 10. So now we can substitute:

$A=1500(1+\frac{0.06}{1} )^{1(10)}$
