Answer:
V = nl^2h or V = nw^2h
Step-by-step explanation:
The computation of the volume of the solid is given below:
Here the volume of the sold would be considered as the volume of 1 prism i.e. rectangular times n
Now as we know that
The volume of a rectangular prism is V is
lwh.
As L = w
Here cross section would become a square
So
V = l^2h
So,
The volume of the resulting solid would be
V = nl^2h or V = nw^2h
The expected number of defective sample is 0.25
<h3>The probability distribution</h3>
The given parameters are:
- Population, N = 30
- Sample, n = 2
- Selected, x = 4
Start by calculating the defective proportion using:
So, we have:
p = 4/30
p = 0.13
The probability distribution is calculated as:
So, we have:
So, the probability distribution is:
x 0 1 2
P(x) 19/25 23/100 1/100
<h3>The expected number of defective sample</h3>
This is calculated using:
So, we have:
E(x) = 0 * 19/25 + 1 * 23/100 + 2 * 1/100
Evaluate
E(x) = 0.25
Hence, the expected number of defective sample is 0.25

What exactly is ur question? This is just a statement
Plz dont be mean to me i just wanna understand and also its the blue line for answer 1
Your answer is v = -2.
To solve this equation, we need to rearrange to get v by itself and then solve:
4 + 3v = -2v - 6
+ 2v
4 + 5v = -6
- 4
5v = -10
÷ 5
v = -2
I hope this helps!
