6_2/5 + (3(1/4)_3/8 + 1/2
Answer: f(x)=|2x+1|+5
f(-3) = |2*-3 + 1|+5
= |-6 + 1|+5
= |-5|+5 = 5 + 5 = 10
f(-3) = 10

Write down the formula for finding the area<span> of a regular </span>polygon<span>. To find the </span>area<span> of a regular </span>polygon<span>, all you have to do is follow this simple formula: </span>area<span> = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.</span>
Answer:
Step-by-step explanation:
Let x be a random variable representing the number of the members of a men’s club that wear black vests to their club meetings. This is a binomial distribution since the outcomes are two ways. It is either they wear black or red. The probability of success, p = 70/100 = 0.7
The probability of failure, q would be 1 - p = 1 - 0.7 = 0.3
a) Number of samples, n = 10
We want to determine P(x ≤ 8)
From the binomial distribution calculator,
P(x ≤ 8) = 0.851
