you would need 32 boxes
Step-by-step explanation:
475/15 = 31.666
Answer:
24
Step-by-step explanation:
So basically, all you have to do is multiply these numbers:
4(-3)(-2) = 24
<h3>
Answer: Choice A. |w - q|</h3>
Let's say for example that w = 10 and q = 7. This means the distance between these values is w-q = 10-7 = 3. This is the distance between w and q.
Now let's make q larger. If w = 12 and q = 20, then w-q = 12-20 = -8 assuming we subtract in the same order. We use absolute value bars to ensure the result is positive. So instead we say
|w - q| = |12 - 20| = | -8 | = 8
Distance is never negative.
Answer:
a) 
And using the normal distribution table or excel we got:

b) 
And we can use the normal standard table or excel in order to find the probability and we got:

Step-by-step explanation:
For this case we know that the random variable of interest is normally distributed with the following parameters:

Part a
We want to find this probability:

And we can use the z score formula given by:

Replacing we got:

And using the normal distribution table or excel we got:

Part b
We select a random sample of size n = 16 and we try to find this probability:

And we can use the z score formula given by:

And replacing we got:

And we can use the normal standard table or excel in order to find the probability and we got:
