The answer is D because the opposite sides are equal to each other, so you have 2 of each measurement. Also, midsegments divide each side of the bigger triangle in half. So 2 (1/2AC + 1/2AB)= the perimeter of the quadrilateral but the 2 in front will cancel out both halves, so we are left with AC+AB (OPTION D)

The chance of rain on a randomly selected day in Western Oregon between June 21st and September 21st is 30% each day. What is th
polet [3.4K]

Answer:

0.47 is the probability it rains at least 2 out of any randomly selected 5 days during the given time of year

Step-by-step explanation:

We are given the following information:

We treat training as a success.

P(Rain) = 30% = 0.30

Then the chances of rain on each day follows a binomial distribution, where

P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 5

We have to evaluate:

P(x \geq 2) =1- P(x = 0) + P(x = 1) \\=1- \binom{5}{0}(0.3)^0(1-0.3)^5 - \binom{5}{1}(0.3)^1(1-0.3)^4\\=1- 0.16807- 0.36015\\= 0.47178 \approx 0.47

0.47 is the probability it rains at least 2 out of any randomly selected 5 days during the given time of year
