A group of 12 male and 8 female students is talking about going out for pizza. If 50% of the male students actually go and 25% of the female students actually go, find the probability that a randomly chosen student is female, given that she is among those who go out for pizza.

1/4

Step-by-step explanation:

12*50%=12*0.5=6 males

8*25%=8*0.25=2 females

2+6=8

2 out of 8 students are female

2/8=1/4

is there any attachment? what are the equations?

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
