Answer: 45.1
Step-by-step explanation:
Answer:
x < 25
Step-by-step explanation:
We need to expand both sides and solve for x.
3(x + 3) > 4(x - 4)
3 * x + 3 * 3 > 4 * x + 4 * (-4)
3x + 9 > 4x - 16
Subtract 3x from both sides:
9 > x - 16
Add 16 to both sides:
x < 9 + 16
x < 25

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
