Answer:
16 hours
Step-by-step explanation:
200 divided by 10 is 20.
320 divided by 20 is 16.
So, 16 hours.
Hope that helps :D.
X= 3
Y=4
I used the substitution method
Here is the correct computation of the question.
The future lifetimes (in months) of two components of a machine have the following joint density function:
for 0 < x < 50 - y < 50, otherwise.
Write down a single integral representing the probability that both components are still functioning in 20 months from now.
Answer:
Step-by-step explanation:
From the given information;
for 0 < x < 50 - y < 50, otherwise.
We can assert that the probability is the integral of the given density over the part of the range 0 ≤ x ≤ 50 - y ≤ 50 in which both x and y are greater than 20.
From the attached file below; their shows a probability density graph illustrating the above statement being said.
Now; to determine the probability that illustrates the integral of the density ; we have : P[(X > 20)∩(Y > 20)]
In addition to that:
From the image attached below;
We look into the region where the joint density under study is said to be positive and the triangle limits by the line axis x+y = 50
∴
Thus; the single integral representing the probability that both components are still functioning in 20 months from now is
Answer:
I know that line AC is the diameter.
I know that line OD is the radius.
However, I am unsure what line BC is supposed to represent.
Sorry, hope this helps :)

Answer:
84 minutes
Step-by-step explanation:
7 people paint 5 walls in =60 minutes
=>1 people paint 1 walls in = (60X7)/ 5 minutes
=>10 people paint 10 walls in = (60X7X10)/(5X10) minutes =84 minutes
