Answer: 353.77
Step-by-step explanation:
Let's start by considering the sector ACB.
The area of this sector is
Now, let's consider the area of triangle ACB. Its area is given by:
So the area of the shaded segment is
B. 65.84 inches
C. 66.55 inches
D. 69.36 inches
Answer:
B. 65.84
Step-by-step explanation:
You are given the armspan and a relation between that and height. Put the given value in the equation and solve for the unknown.
... 67.5 = 1.123x -6.443
... 73.943 = 1.123x
... 73.943/1.123 = x = 65.84
Riley's height is predicted to be 65.84 inches.
Answer:
t = 13 days
p(13) = 33.47%
Step-by-step explanation:
p(t) is the percentage of the population infected:
p(t) = 7*t*e∧(-t / 13)
where 0 ≤ t ≤ 39 days
we can apply p'(t) = 0 to get number of days where the percentage of infected people is maximum:
p'(t) = (7*t*e∧(-t / 13))' = 7*(t*e∧(-t / 13))' = 7*((t)'*e∧(-t / 13)+t*(e∧(-t / 13)') = 0
⇒ 7*(1*e∧(-t / 13)+t*e∧(-t / 13)*(-1 / 13)) = 7*e∧(-t / 13)*(1 - (t / 13)) = 0
∴ 1 - (t / 13) = 0 ⇒ t = 13 days
then we get the maximum percent of the population infected as follows
p(13) = 7*13*e∧(-13 / 13)
⇒ p(13) = 33.47%
B) What is the probability that a component works perfectly well (i.e., neither displays strain nor fails the test)?
C) What is the probability that the component either fails or shows strain in the test?
Answer: a. 0.61
b. 0.37
c. 0.63
Step-by-step explanation:
From the question,
P(A) = 0.39 and P(B) = 0.24
P(success) + P( failure) = 1
A) What is the probability that the component does not fail the test?
Since A is the event that the component fails a particular test, the probability that the component does not fail the test will be P(success). This will be:
= 1 - P(A)
= 1 - 0.39
= 0.61
B) What is the probability that a component works perfectly well (i.e., neither displays strain nor fails the test)?
This will be the probability that the component does not fail the test minus the event that the component displays strain but does not actually fail. This will be:
= [1 - P(A)] - P(B)
= 0.61 - 0.24
= 0.37
C) What is the probability that the component either fails or shows strain in the test?
This will simply be:
= 1 - P(probability that a component works perfectly well)
= 1 - 0.37
= 0.63
