4% of the lightbulbs produced at Shady Stan's lightbulb factory are defective. An inspector visits the factory and randomly grab
1 answer:
Answer: Mean = 8 and standard deviation is 2.77
Step-by-step explanation:
The mean and standard deviation for a binomial distribution is given by :-
, where n is the sample size and p is the probability of getting success.
Given : The proportion of the lightbulbs produced at Shady Stan's lightbulb factory are defective: p=0.04
Sample size :
Then , the mean and standard deviation for a binomial distribution is given by :-

1) Slope tell about the steepness of the line.
To find slope we look at the rise and run between 2 points.
attached the graph of line with slope
slope =
=
So slope = 2
2) we have x and y intercepts
x intercept is the point where the line crosses x axis
x intercept at x= 3
y intercept is the point where the line crosses y axis
y intercept at y= 6
3) Linear equation is y= 3x+2
function is f(x) = 3x+2
We can graph it using slope and y intercept
In f(x)= 3x + 2 , slope =3 and y intercept = 2
slope = 3, rise = 3 and run =1
The graph of f(x)= 3x+2 is attached below.
The formula of a slope:
We have the points A(-7, a) and B(c, d).
Substitute:
Exception: c ≠ -7.
See the attached picture.
