A local gym offers its members the opportunity to choose between two fitness classes: yoga and dance. Of the 400400400 gym members, 300300300 regularly attend yoga, 808080 regularly attend dance, and 505050 regularly attend yoga and dance. Using this information, answer each of the following questions.
Let YYY be the event that a randomly selected gym member regularly attends yoga and DDD be the event that a randomly selected gym member regularly attends dance.
What is P(Y)P(Y)P, left parenthesis, Y, right parenthesis, the probability that a gym member attends yoga?

1/5x+9 2/5y+7

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
