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
Answer: 12.56 feet
Step-by-step explanation:
Given: The width of the circular path= 2 feet
The inner diameter of circular path= 150 feet
Therefore, the inner radius of circular path=
Now, the outer radius= 75+2=77 feet
We know that the circumference=
Inner circumference=
Outer circumference=
The difference=
Hence, the outer edge of the path is 12.56 feet farther than the inner edge
Answer:
20%
Step-by-step explanation:
Now, there are 60 minutes in 1 hour, thus 20 minutes is just 20/60 or 1/3 of an hour.
Ifthe roots are r1 and r2
then the factored form is
a(x-r1)(x-r2)
so
and multpilcty is how many times the root repeats
P(x)=(x-0)^4(x-2)^3(x-(-1))^2
so the roots are 0 multipilcty 4, 2 mupliticty 3, -1 multplity 2
