Answer:

Yes, snow and cold weather are independent.

Step-by-step explanation:

We are given the following in the question:

C: Cold weather

S: Snow

P(C) = 0.50

P(S) =0.30

P(S\cap C) = 0.15

We have to check whether snow and cold whether are independent events.

If the events A and B are independent then,

p(A\cap B) = P(A)\times P(B)

Checking,

p(S\cap C) = P(S)\times P(C)\\0.15 = 0.30\times 0.50

Thus, the two events are independent.

For mutually exclusive events

P(A\cap B) = 0

Thus, the given events are not mutually exclusive.

Mrs. Simpson drove 105 miles in 2 1/2 hours. What was Mrs. Simpson's average speed in miles per hour?
harkovskaia [24]
105 m = 2.5 h
 
x miles = 1 hour

You cross multiply since it's a proportion:
2.5 * x
105 * 1

=

2.5x = 105

Then you divide everything by 2.5

The answer is 42

Multiply me by 4 then subtract 13 if you divide me by 3 and add 17 you get 22
8_murik_8 [283]
You have to do the opposite

22-17=5
5x3=15
15+13=28
28/4=7

The answer is 7. You can check this by doing what it says and if it makes 22, it’s correct. (I’ve already checked it) :)
