Raul has 50 coupon books to sell. The total amount of money Raul will make from selling x coupon books is represented by a function. f(x)=20x

What is the practical domain of the function?

all integers from 0 to 50, inclusive

all integers from 20 to 50, inclusive

all multiples of 20 between 0 and 1000, inclusive

all real numbers

The domain of a function is the set of its possible inputs .The output values are called the range.For any  the set of values x can take is called the domain of the function.

The given function is f(x)= 50x .Here x represents number of coupons . f(x) represents The total amount of money Raul will make .

It is given Raul started with 50 coupon books and has already won a prize for selling at least 10 coupon books .

The values x can take or the domain of the function will lie between  10 and 50.

The correct option is  All integers from 0 to 50, inclusive .

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.
