Question

84, 86, 83, 78, 92, 87, 92, 90, 88, 86 Which dot plot correctly shows his scores​

Answer 1

C)

Explanation:

Given scores are 84, 86, 83, 78, 92, 87, 92, 90, 88, 86. First arrange them in ascending order. Let's first understand what is ascending order. Ascending order is the process of arranging numbers from smallest value or number to largest one.

Ascending order of scores: 78, 83, 84, 86, 86, 87, 88, 90, 92, 92.

→ 78 will come between 75 and 80.

→ 83, 84 will come between 80 and 85.

→ 86, 87, 88 will come between 85 and 90.

→ 90 at 90th point.

→ 92 will come between 90 and 95.

PS: One cross represents a number, while two crosses means the number will appear twice.

Answer 2

[C]

Explanation:

Given data:

84, 86, 83, 78, 92, 87, 92, 90, 88, 86

Solve:

we have

1 - 84

2 - 86

1 - 83

1 - 78

2 - 92

1 - 87

1 - 90

1 - 88

Thus, we can conclude that:

[A] is wrong since there is no 82, and there no two 90.

[B] is wrong since there is no three 86 and well as missing some number like 90.

[C] is correct since all the given above is there.

[D] is wrong because there only one 84 and one 88.

Hence, [C] is correct answer.
