Space shuttle astronauts each consume an average of 3000 calories per day. one meal normally consists of a main dish, a vegetable dish, and two different desserts. the astronauts can choose from 10 main dishes, 8 vegetable dishes, and 13 desserts. how many different meals are possible?

  12,480

Step-by-step explanation:

For each of one, you can have any of the others. The total possible is the product of the numbers of possibilities for each:

  (# main dishes)×(# vegetables)×(# first dessert)×(# second dessert)

  = 10 × 8 × 13 × 12 = 12,480

Since the desserts are different, there are 13 possibilities for the first one, but that choice is eliminated from the possibilities for the second one.

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.
