Answer:

Dot plot, because a small number of scores are reported individually.

Step-by-step explanation:

Histogram is usually used when a group of data to be represented is usually large and given in ranges or intervals.

However, for a data set, such as the scores of the group of 12 students who participated in a dance competition are reported individually, and not as ranges or intervals, a dot plot would best for representing this small number of scores.

See attachment below to see how we can easily represent the given scores of the students on a dot plot. Each dot represents a score value for each student.

Answer:

15th term = 116

Step-by-step explanation:

a= 4

Sum of an A.P = n/2 {2a + (n-1)d}

sum of first five term is equal to one-fourth of the sum of the next five term

5/2{ 2*4 + (5-1)d} = 1/4 × 10/2{2*4 + (10-1)d

5/2 {8 + 4d} = 1/4 × 5{ 8 + 9d}

40/2 + 20/2d = 1/4{ 40 + 45d)

20 + 10d= 40/4 + 45/4d

20 + 10d = 10 + 45/4d

20 - 10 = 45/4d - 10d

10 =45d - 40d /4

10 = 5/4d

Divide both sides by 5/4

10 ÷5/4 = d

10×4/5 = d

40/5 = d

8 = d

d= 8

Find the 15th term

15th term = a + (n-1)d

= 4 + (15-1)8

= 4 + (14)8

= 4 + 112

= 116

The 15th term is 116

120 + b = 180

b = 180 - 120 = 60

a + 30 = 180

a = 180 - 30 = 150
