A local gym offers its members the opportunity to choose between two fitness classes: yoga and dance. Of the 400 gym members, 300 regularly attend yoga, 80 regularly attend dance, and 50 regularly attend yoga and
dance. Using this information, answer each of the following questions.
Let Y be the event that a randomly selected gym member regularly attends yoga and D be the event that a
randomly selected gym member regularly attends dance.
What is P(Y), the probability that a gym member attends yoga?
What is P(D), the probability that a gym member attends dance?
What is P(Y and D), the probability that a gym member attends yoga and dance?
What is P(Y or D), the probability that a gym member attends yoga or dance?

i would you but i don't under stand the qustion

step-by-step explanation:

1260=3*6*7*10=3^2*2^2*7*5 perfect cude = 3^3*2^

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
