Y=3x-4
if you’re ever unsure just plug in the numbers on the chart into the equations and see which ones work
312 people bought balcony seats and 396 people bought ground seats.
A. 2x3=6 and 6x12=72 so 78 is greater than 36
6+72=79 which is less than 90
Answer:
It is binomial:
p= 0.75 = 75%
1-p = 0.25 = 25%
N = 10
k=7
"seven successes in 10 trials"
(10 choose 7) (0.75)^7 ( 0.25)^3 =
(10*9*8 / 3*2) * (0.75)^7 ( 0.25)^3 =
(5*3*8) (0.75)^7 ( 0.25)^3
120 (0.75)^7 ( 0.25)^3
= 0.25028228759765625
or just over 25%
Step-by-step explanation:
The answer is 19 because you have to divide them
