The volume of the rectangular prism is 3 / 4 inches³
<h3>Volume of a right rectangular prism</h3>
The volume of a right rectangular prism is describe as follows;
where
l = length
w = width
h = height
The rectangular prism is made up of 48 cubes. Each cube has an edge length of 1 / 4 inches.
The volume of the rectangular prism is the sum of the volume of the cubes.
Therefore,
- volume of each cube = (1 / 4)³ = 1 / 64
The cubes are 48 in number. Therefore,
volume of rectangular prism = 1 / 64 × 48 = 48 / 64
volume of rectangular prism = 3 / 4 inches³

Answer:
Emily had $24 to begin with.
Fred had $21 to begin with.
Step-by-step explanation:
We know that both Emily and Fred gave Gary, who had no money, a total of $15. We also know that now they have the same amount of money (they all have $15). We simply have to add the values each person gave to Gary:
Emily: 15 + 9 = 24
Fred: 15 + 6 = 21
Answer:
Option C is right
Step-by-step explanation:
Given are two samples
I group has sample size 90, mean = 9.2 and std dev =0,.37
II group has sample size 70, mean = 7.3 and std dev = 0.58
we find that mean difference i.e. difference between mean hours of sleep between two groups
= 9.2-7.3 = 1.9
Std error for difference = 0.0620
Since sample size is sufficiently large we can use Z critical for 99%
i.e. 2.58
Margin of error =±2.58(0.062)
=0.16
Hence confidence interval 99% for difference in hours of sleep
= (1.9-0.16,1.9+0.16)
=(1.74, 2.06)

y = 2/5
Step-by-step explanation:
Answer:
- 4
Step-by-step explanation:
(2*(Rationalize(9.7)-Rationalize(4.8x)))==Rationalize(61.2)-Rationalize(3.4)
Rationalize(18.4)-Rationalize(2.8x)
==Rationalize(57.8)
-Rationalize(2.8x)==Rationalize(57.8)-Rationalize(18.4)
x= 38.4÷-2.8
:x= -4
