The answer is A. When you take the 9s and the -2s, you get 7s. Then you add the 3x5 and end up with 15. Giving you the answer 7s+15
<h2>Answer: </h2>
1. <u>Area = b × h</u>
A = 5 × 3
A = 15cm².
2. <u>Area = ½(a + b) × h</u>
A = ½(9 + 15) × 15
A = ½ × 24 × 15
A = 12 × 15
A = 180mm².
3. <u>Area = 2(l × b) + l × b</u>
A = 2(12 × 4) + 6 × 3
A = 2 × 48 + 18
A = 96 + 18
A = 114m².
The answer is b. Thank you
The expected values of the binomial distribution are given as follows:
1. 214.
2. 21.
3. 31.
<h3>What is the binomial probability distribution?</h3>
It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
For item 1, the parameters are:
p = 3/7, n = 500.
Hence the expected value is:
E(X) = np = 500 x 3/7 = 1500/7 = 214.
For item 2, the parameters are:
p = 0.083, n = 250.
Hence the expected value is:
E(X) = np = 250 x 0.083 = 21.
For item 3, the parameters are:
p = 1/13, n = 400.
Hence the expected value is:
E(X) = np = 400 x 1/13 = 31.

Answer:
The second choices is the answer
{(-6,6), (8, 2), (8, -1), (3,3)} as you can see there's a repeating value of x or the Domain which is the 8.
