A batsman scored the following number of runs in six innings: 35, 30, 45, 65, 44, 21. Calculate the mean runs scored by him in
(a) 39
(b) 38
(c) 37
(d) 40

D

Step-by-step explanation:

The mean or average is calculated by summing each element and then dividing by the number of elements.

We have: 35, 30, 45, 65, 44, and 21.

There are six elements in total.

We find the sum by adding. Hence:

We will now divide by 6, the number of elements:

Therefore, the mean runs scored by the batsman is 40.

Hence, our answer is D.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
