11. You have one coupon for 15% off on one pound of pork chops. They cost $7 per
pound. How much will 3 pounds cost?

$19.95

Step-by-step explanation:

The total cost for 3 pounds can be found using:

1 pound + 1 pound + 1 pound

We know that there is a coupon for 15% off one pound. Normally you pay for 100%, but since there is 15% off (subtracted), you only pay 85%. (100%-15%=85%)

Multiply 85% and $7.

85%* $7

Convert 85% to a decimal by dividing 85 by 100.

85/100= 0.85

0.85 * $7

Multiply

$5.95

Now we know that 1 discounted pound costs $5.85. The other 2 pounds are regularly priced at $7 each.

1 pound + 1 pound + 1 discounted pound

$7 + $7 + $5.95

$14 + $5.95

$19.95

3 pounds will cost $19.95

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
