Answer:
Step-by-step explanation:
Given
Let
A = Event of being a universal donor.
So:
Solving (a): Mean and Standard deviation.
The mean is:
The standard deviation is:
Solving (b): P(x = 3)
The event is a binomial event an dthe probability is calculated as:
So, we have:
The formula for circumference is C = 2πr.
The question gives you the circumference (C in the formula), and you need to find the radius (r in the formula). Begin by isolating r in the circumference formula.
C = 2πr
C/2π = r
r = C/2π
Now you can plug 96 for C and solve to find r.
r = C/2π
r = 96/2π
r ≈ 96/6.28
r ≈ 15.29
Answer:
The radius of a circle with a circumference of 96 feet is approximately 15.29 feet.
Hi,
The answer to your question is either A or B.
The y-intercept is at point (0,60). All the other options (C and D) do not make sense and just aren't logically.
The y-intercept (0,60) literally shows that if a student studies 0 hours they can expect to score a 60 on the test.
Thus, you're answer is option B.
