Answer:
VW = 16
Step-by-step explanation:
Given UX is a midsegment then it is one half of the parallel side VW, thus
VW = 2UX , substitute values
p - 5 = 2(p - 13) ← distribute
p - 5 = 2p - 26 ( subtract 2p from both sides )
- p - 5 = - 26 ( add 5 to both sides )
- p = - 21 ( multiply both sides by - 1 )
p = 21
Thus
VW = p - 5 = 21 - 5 = 16
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

Your angles have to equal 90 and 180 degrees
So you would have to subtract from the angles and the numbers
Answer:
4:18 and 6:27
Step-by-step explanation:
Answer: 6.6
You can divide 66 by 10 to get the answer. To do it quickly, just move the decimal point in 66 to the left one spot
