Answer:
0.053
Step-by-step explanation:
This is a geometric distribution problem.
I'm geometric distribution problem,
E(X) = 1/p
Where;
E(X) is expected value and p is probability of success
Thus;
1/p = 12.5
p = 1/12.5
p = 0.08
Now, to find the probability that the sixth person tested is the first one with high blood pressure, we will use the probability formula in geometric distribution which is;
P(X = k) = qⁿ•p
q = 1 - p
q = 1 - 0.08
q = 0.92
Thus;probability that the sixth person tested is the first one with high blood pressure will be expressed as;
P(X > 5) = (0.92^(5)) × 0.08
P(X > 5) = 0.053

OMGGGG SO CUTEEE!!!
Step-by-step explanation:
-6
Step-by-step explanation:
a minus this is always a positive so you figure if 33 positive it would be 17 + 6 equals 33

Answer:
4) smaller number is 9, larger number is 12
13) 38.45=5m+8.5
m=5.99
Step-by-step explanation:
x+y=21 the sum of two numbers is 21
x-3=.5y the smaller number is 3 more than half the larger number
multiply both sides by 2 and you get 2x-6=y
plug that equation into the first equation and you get x+2x-6=21
simplifying you get 3x-6=21 add 6 to both sides and you get 3x=27
x=9 so the smaller number is 9 then you plug that back into the first equation and get y=12
let m be the cost of 1 movie and c be the cost of the cd
38.45=5m+c
38.45=5m+8.5 this is the equation you use
subtract 8.5 from both sides and you get 29.95=5m
divide both sides by 5
5.99=m the answer
