P = 2(L+W)
L = 12+W
P = 64 inches
64 = 2(12+W+W)
64 = 2(12+2W)
64 = 24+4W
64-24 = 4W
40 = 4W
W = 10 inches
L = 12+W
L = 12+10
L = 22 inches

Answer: What is the total number of students who brought water bottles to lunch?
A statistical question is a question with data that will vary.
Answer:
B. 1/8
Step-by-step explanation:
Answer:
0.50
Step-by-step explanation:
Let A represent the probability that it will be cloudy
Let B represent the probability that it will be rainy
P(A) = 0.40
P(B) = 0.30
P(A and B) = 0.20
For non mutually exclusive events the probability of event A or B is
P(A or B) = P(A) + P(B) - P(A and B)
= 0.40 + 0.30 - 0.20
= 0.50
There is a 50% probability that the picnic will be postponed. Therefore the probability that the picnic will not be postponed is equals 1 - P(A and B)
= 1 - 0.50
= 0.50 or 50%
