Perimeter is adding all 4 sides together:
8 + 8 + 9x + 9x
Simplify by coming like terms to get:
18x + 16
The answer is d. 18x + 16
We have the formula to compute the probability of having exactly k successed over n trials, given a probability p of success (and implicitly a probability 1-p of failure), which is

Now, the probability of at least 3 successes is the union of the following event: exactly three successes,exactly four successes and exactly five successes.
We can compute their probability and sum them:
So, the answer is about 36.79%
Answer:
They're the same angle. I would look up transversals so you could understand it a bit more. I'll upload a picture of a transversal in my answer but you should search it anyways.
Anyways,
To solve, you set 160 equal to the other side.
160 = 3x + 10
150 = 3x
x = 50

- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>trucks/cars = 2/3 = x/9 = 30/y</em>
<em>x = 2×9/3 = 18/3 = 6</em>
<em>y = 3×30/2 = 90/2 = 45</em>
<em>Good luck ! </em>
Answer: 360
Step-by-step explanation:
Since we are informed from the question that Alicia surveyed 50 students in the cafeteria from the population of 300 students, it simply means that she surveyed 50/300 = 1/6 of the students.
Since Thea surveyed the first 60 students who arrived at school one morning, the number of T-Shirts taht they should order will be:
= 1/6 × x = 60
x = 60 × 6.
x = 360
They should order 360 t-shirts for the students.
