Questions and Answers
Q 1 - The two bars in a bar graph have heights 16 and 26. What height a new bar should have so that it has the mean height of the two bars?

Answer : A

Explanation

Step 1:

Heights of given bars 16, 26

Step 2:

Mean height = $\frac{(16 + 26)}{2} = \frac{42}{2}$ = 21

So height of new bar = 21

Q 2 - The two bars in a bar graph have heights 12 and 18. What height a new bar should have so that it has the mean height of the two bars?

Answer : C

Explanation

Step 1:

Heights of given bars 12, 28

Step 2:

Mean height = $\frac{(12 + 18)}{2} = \frac{30}{2}$ = 15

So height of new bar = 15

Q 3 - The two bars in a bar graph have heights 16 and 22. What height a new bar should have so that it has the mean height of the two bars?

Answer : B

Explanation

Step 1:

Heights of given bars 16, 22

Step 2:

Mean height = $\frac{(16 + 22)}{2} = \frac{38}{2}$ = 19

So height of new bar = 19.

Q 4 - The two bars in a bar graph have heights 14 and 26. What height a new bar should have so that it has the mean height of the two bars?

Answer : D

Explanation

Step 1:

Heights of given bars 14, 26

Step 2:

Mean height = $\frac{(14 + 26)}{2} = \frac{40}{2}$ = 20

So height of new bar = 20

Q 5 - The two bars in a bar graph have heights 15 and 19. What height a new bar should have so that it has the mean height of the two bars?.

Answer : C

Explanation

Step 1:

Heights of given bars 15, 19

Step 2:

Mean height = $\frac{(15 + 19)}{2} = \frac{34}{2}$ = 17

So height of new bar = 17
