Answer:
<h3>Therefore, So the correct answer is 0.3446</h3>
Step-by-step explanation:
Suppose parts A and B have a lifetime that is normally distributed with mean 110 hours and standard deviation 5 hours. Suppose further that parts A and B work independent of each other. What is the probability that the electric device works more than 112 hours
Here it is given that distribution is normal with
mean = 110 and standard deviation = 5
Now we need to find
P (x > 112)
As distribution is normal we can convert x to z
<h3>Therefore, So the correct answer is 0.3446</h3>
The lines that intersect at Park Avenue and Hawthorne Boulevard are perpendicular to each other because they intersect at a 90 degree angle.
Answer:
B
Step-by-step explanation:
the solution to a system of equations is at the points of intersection of the 2 lines.
the given lines only intersect once , thus there is only 1 solution
