Answer:
For #2: It's C. 17 nickels and 15 quarters.
Step-by-step explanation:
17*5= 85
15*25= 375
375+85= 460
add in the decimal:
17* 5 cents= $.85
15* 25 cents= $3.75
$3.75+ $.85= $4.60
Answer:
Step-by-step explanation:
Given
--- interval
Required
The probability density of the volume of the cube
The volume of a cube is:
For a uniform distribution, we have:
and
implies that:
So, we have:
Solve
Recall that:
Make x the subject
So, the cumulative density is:
becomes
The CDF is:
Integrate
Expand
The density function of the volume F(v) is:
Differentiate F(x) to give:
So:
A. 6082
B.120687
C.1188228
D.19042587
If
is left, that means
was spent. So
of the total amount is equal to 39.. Let's say x to the total amount.
yes it does have enough to cover the cube
