Answer:
137
Step-by-step explanation:
m∠B and m∠C are adjacent angles in a parallelogram.
Sum of adjacent angles in a parallelogram is 180.
m∠B + m∠C = 180
43 + m∠C = 180
m∠C = 180 - 43
m∠C = 137
Let events
A=Nathan has allergy
~A=Nathan does not have allergy
T=Nathan tests positive
~T=Nathan does not test positive
We are given
P(A)=0.75 [ probability that Nathan is allergic ]
P(T|A)=0.98 [probability of testing positive given Nathan is allergic to Penicillin]
We want to calculate probability that Nathan is allergic AND tests positive
P(T n A)
From definition of conditional probability,
P(T|A)=P(T n A)/P(A)
substitute known values,
0.98 = P(T n A) / 0.75
solving for P(T n A)
P(T n A) = 0.75*0.98 = 0.735
Answer:
The probability that the time between two successive student arrivals at Benson is greater than 2 minutes is 0.000335.
Explanation:
The arrival rate of students is 4 students per minute.
The time between 2 successive arrivals is a random variable having exponential distribution.
The formula for exponential distribution is:
where L = Arrival rate of students (per minute) = 4
Hence,
We require the probability that the time between two successive arrivals is greater than 2 minutes. Therefore,
Answer:
What do u need help with I don't get what u need help with
Step-by-step explanation:
Hi,
So we have g(x) = 4√(x). We're looking for g(45). Think of it like this: whatever number is in the place of x in g(x), just place that number AS x.
Therefore, we have :
g(45) = 4√(45) ⇒ (4) × (√(45)) ⇒ (4)(3√(5)) = 12√(5).
-Hope this helps!
