Ms. Harwood drives a minivan that gets an average of 22 1/2 miles per gallon of gasoline. The tank on the minivan holds 18 gallons. How far can Ms. Harwood drive on 1/2 of a tank of gasoline?
11 1/4 miles
112 1/2 miles.
202 1/2 miles
405 miles

405 miles

Step-by-step explanation:

Take the miles per gallon and multiply the gallons to get the miles

22.5 * 18

405 miles

202 1/2 miles

Step-by-step explanation:

We want to find how far she can drive on 1/2 a tank of gas.

Her tank can hold 18 gallons. Multiply 18 and 1/2, or divide 18 by 2.

18*1/2=18*0.5=9

or

18/2=9

1/2 a tank of gas is 9 gallons. Now, we need to find how far she can drive. Multiply the number of gallons in 1/2 a tank by the miles per gallon.

gallons in 1/2 tank * miles per gallon

We know she has 9 gallons in 1/2 tank, and she gets 22 1/2, or 22.5 miles per gallon.

9 gallons * 22.5 miles/gallon

9*22.5=202.5= 202 1/2

She can drive 202 1/2 miles on 1/2 a tank of gas.

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.
