Answer:

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

And replacing we got:


We can find the probability of interest using the normal standard table and with the following difference:

Step-by-step explanation:
Let X the random variable who represent the expense and we assume the following parameters:

And for this case we want to find the percent of his expense between 38.6 and 57.8 so we want this probability:

And we can assume a normal distribution and then we can solve the problem with the z score formula given by:

And replacing we got:


We can find the probability of interest using the normal standard table and with the following difference:

Answer:
√y/y c.
Step-by-step explanation:
2y/√4y^3
= 2y / 2 y^3/2
= 1 / √y
= √y/y

Answer:
A
Step-by-step explanation:
Let's see...
It's a cube, so the total volume will be one length cubed or 10^3 which is 1000.
(2500 g)/(1000 cm^3) =
