Answer:
B
Step-by-step explanation:
Minimum L = 45
Maximum L = 180
L(w) = 3w - 27
Therefore, when 45 = 3w - 27 ⇒ w = 24
when 180 = 3w - 27 ⇒ w = 69
So 24 ≤ w ≤ 69
Therefore, the answer is B
It would be A on both questions
First Question
1.99+1.50=3,49
3.49 x 2=6.98
6.98+1.40=8.38
20-8.38=$11.62
Second Question
22.50 x 2=45
45+35.50+7.18=87.68
87.68/2=43.84
We are given frequency distribution in the question
to find the probability distribution from frequency distribution we need to divide frequency by total number of observations.
Here, total number of observations are 6+10+7+5=28
so , we will have probability distribution table as
X 0 1 2 3
P(x) .21 .35 .25 .17
probability distributiuon describes all possible values that a random variable can take within a given range.
frequency distribution is the presentation that presents number of observation in given interval.
X+12 is the answer to your question
(x+y)(x-8)
is your answer
