Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. after running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. he converts the average rate to feet per second as shown below:
he concludes that she is not running fast enough to exceed her fastest time

Correct: He used an incorrect time ratio converting hours to minutes.

X His units do not cancel.

X He used an incorrect distance ratio converting miles to feet.

Correct: He incorrectly concluded that she is not running fast enough.

X He cannot determine her average rate in miles per hour after only 15 minutes.

✓He used an incorrect time ratio converting hours to minutes.

X His units do not cancel.

X He used an incorrect distance ratio converting miles to feet.

✓ He incorrectly concluded that she is not running fast enough.

X He cannot determine her average rate in miles per hour after only 15 minutes.

Step-by-step explanation:

see below

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.  

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
