Answer: You will need to add all the number up
Step-by-step explanation:
Segment JI is a midsegment (given). So that means point J is a midpoint of segment HF. The midpoint cuts HF into two equal pieces. Those two pieces are HJ and JF. Therefore, HJ = JF
Using substitution, we can plug in the given expressions that the diagram shows. Then we can solve for x
HJ = JF
2x-3 = x+2
2x-3+3 = x+2+3
2x = x+5
2x-x = x+5-x
x = 5
Now that we know x = 5, use this to find the length of HG
HG = 11*x + 5
HG = 11*5 + 5
HG = 55 + 5
HG = 60
So HG is 60 inches long, which is the final answer
Note: 60 inches = 5 ft
⇒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.
The area of a circle is pi*r^2.
The angles in a circle add up to 360 degrees.
Let's say I have a circle with radius 2.
The total area of the circle is pi* (2^2) = 4pi
Let's say I cut out 15 degrees of this circle. This piece is 15 out of 360 of the whole circle.
The area of this part is (15/360) * 4pi
The rest of the area is (360-15)/360 * 4pi.
I hope this helps.
