Complete the two-way frequency table below, which shows the relationship between student gender in a particular class and whether students wear jeans. From a sample of 40 students, it is found that there are 22 females, 25 people in the class who are wearing jeans, and 7 females not wearing jeans. Jeans No Jeans Total
Female 7 22
Male
Total 25 40

What is the probability (rounded to the nearest whole percent) that a student will be a female given that he or she wears jeans? Are the events being female and wearing jeans independent? (4 points)

60%; they are not independent

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
