Step-by-step explanation:
<u>Given sets</u>
- R = {10, 15, 20}
- S = {20, 25}
<u>Intersection of sets</u>
Answer:
40.5
Step-by-step explanation:
i would recommend changing the 90% into a decimal
90% ⇒ .90
then now you can just multiply .90x45
.90x45=40.5
⇒The Variance tells us spread between each variate in data set from mean.
Now, Coming to the Question
⇒Sample of 14 students were taken from a population of 168 students.
Variance =Expected value of square of each variate taken from mean, which can be represented as

Size of Sample taken in terms of Percentage

⇒Sample Size is Approximately only 8.4% of total Population,which is very small, that can't represent the whole Population Variance.
Option B:→ 14 , is most appropriate, which Represents the Variance of 14 student height.
Start with <span>3x+2>x+8.
Subtract x from both sides, obtaining: 2x + 2 > 8.
Subtract 2 from both sides, obtaining: 2x > 6
Divide both terms by 2: x > 3 (answer)</span>
