Answer:
the rate at which the distance between the planes is changing is 825 each hour
Step-by-step explanation:
The computation of the rate at which the distance between the planes is changing is shown below
= Travelling one plane + travelling another plane
= 450 mph + 375 mph
= 825 mi each hour
Therefore the rate at which the distance between the planes is changing is 825 each hour
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Given:
The probability for success of an event is P(A)
The probability of success of a second, independent event is P(B).
To find:
The probability of both events occurring, in that order.
Solution:
If A and B are two independent events, then

It is given that,
The probability for success of an event is P(A)
The probability of success of a second, independent event is P(B).
Since A and B both are independent event and we need to find the probability of both events occurring, in that order, i.e.,
, therefore
.
Hence, the correct option is A.
Consider the number of the adult tickets is x
X+2x=276
3x=276
X=92
So the student tickets is =184
The answer is A) 3.
I hope this helps.
