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>
Answer:
The bench costs $425
And the Table costs $510
Step-by-step explanation:
table + bench = $ 935
$85 + 2b = $935
$935 - $ 85 = $ 850
$850/ 2 = 425 = b
The first thing you should know is the following conversion:
1h = 60min
What you can do to solve the problem is the use of a rule of three:
60 ---> 3.8
165 ---> x
Clearing the value of x we have:
x = (165/60) * (3.8) = 10.45
x = 10.45 mi
answer
she can walk 10.45 mi in 2 hours 45 minutes
Answer:
Yes
Step-by-step explanation:
The definition of a terminating decimal is that it has a definitive end. In the case of -0.6875, it has an end to it and does not go one forever, making it a terminating decimal. An example of a non-terminating decimal could be which keeps going on and on forever. -0.6875 has a definitive end thus making it terminating.
