Using the binomial distribution, it is found that:
- The mean of X is of 0.72.
- The standard deviation of X is of 0.81.
<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>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
The standard deviation of the binomial distribution is:
For this problem, the parameters are given as follows:
n = 8, p = 0.09.
Hence the mean and the standard deviation are, respectively:
- E(X) = np = 8 x 0.09 = 0.72.

Answer:
Option B, would be the correct answer: 75 labels per minute
Step-by-step explanation:
The number of labels produced per minute would be a constant value which would be the slope of this graph represented above.
Slope = 
Slope = 
Slope = 75
Hope this helps!
Answer:
non linear
Step-by-step explanation:
the graph is showing more of a parabola than a linear line
Hi,
The total amount is $1,350.
<em /><span><em>So, firstly we'll start off with the easiest one. We know that they bought a cake for </em><em>$250</em><em>. We also know that there were </em><em>50 people </em><em>invited. Appetizers per person cost $2. So we multiply $2 by 50 people. That's $100. They also charge $20 per person for the main course. Now we multiply $20 by 50 people and get $1,000. Now we add $1,000, $250, and $100 to get our total!</em></span>
Answer:
y = 3x + 3
Step-by-step explanation:
when you check, only that equation delivers the correct x and y pairs.
x = 0, => y = 3×0 + 3 = 3
x = 1, y = 3×1 + 3 = 3+3 = 6
x = 2, y = 3×2 + 3 = 6 + 3 = 9
x = 3, y = 3×3 + 3 = 9 + 3 = 12
it all fits.
