Answer:
0.625 = 62.5% probability that part B works for one year, given that part A works for one year.
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
The probability that part A works for one year is 0.8 and the probability that part B works for one year is 0.6.
This means that
The probability that at least one part works for one year is 0.9.
This means that:
We also have that:
So
Calculate the probability that part B works for one year, given that part A works for one year.
0.625 = 62.5% probability that part B works for one year, given that part A works for one year.
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is a linear equation (the graph is a line)
To identify the graph find out the intercepts
<u><em>Find out the y-intercept</em></u>
The y-intercept is the value of y when the value of x is equal to zero
For x=0
The y-intercept is the point (0,-4)
<u><em>Find out the x-intercept</em></u>
The x-intercept is the value of x when the value of y is equal to zero
For y=0
The x-intercept is the point (5.33,0)
therefore
The graph in the attached figure
When a population or group of something is declining, and the amount that decreases is proportional to the size of the population.
Have a good day!!
Answer:
slope that is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(- 3, 5) and (x₂, y₂ ) = B(- 3, 3)
m = =
Division by zero is undefined
Thus the slope of AB is undefined
