Answer:
3/26 students or 11%
Step-by-step explanation:
probability dependant formula:P(A∪B)=P(A)+P(B)−P(A∩B)
P(a)= basketball
P(b)=baseball
so
P(AUB)=P(A)+P(B)-P(A∩B)= 18/26+5/26-20/26=3/26
3/26 or 11%
OR you could solve this by adding all the sport/non sport #'s 18+5+6=29 and subtract 26 from 29
29-26=3
hence 3/26 students would randomly play basketball or baseball
Hope this Helps!
Answer:
x = 12
Step-by-step explanation:
they are virtical menaing they are the same value
6x + 7 = 8x - 17
6x + 24 = 8x
24 = 2x
12 = x
Answer:
3) x=4 4)x = 9 5) x=5
Step-by-step explanation:
3) first you have to find the inside of the angle. A straight line = 180*
180-(19x+3) = 177-19x
Than you add all the angles up to equal 180.
(177 - 19x) + (11x-2) + (9x+1) = 180
if you simplify this x = 4. You can check your answer by subbing in for x.
4)first you have to find the inside of the angle. A straight line = 180*
180- (17x-23) = 203-17x
Than add the sides up to equal 180. keep in mind there are 2 of the same angles.
(203-17x)+(7x+2)(2) = 180
Simplify
x=9
5) 180-151=29* this is the inner angle.
(11x-1)+(20x-3)+29=180
31x+25=180
x=5
