Prepare grouped frequency distribution table

1 answer:

6 0

The frequency distribution gives a tabulated representation of the frequency of data values within defined intervals.

Given the scores :

8, 47, 22, 31, 17, 1,38 ,26 ,3 ,34,29,11,27,7,15,24,38,31,21,35,42,42,24,45,23,21,27,29,49,25,48,21,15,18,27,19,45,14,34,37,34

Using a class interval value of 10 :

Class Interval _____ Frequency

0 - 10 ____________ 4

11 - 20 ____________7

21 - 30____________14

31 - 40 ____________9

41 - 50 ____________7

Histogram of the distribution is attached below.

Therefore, the histogram gives a graphical representation of the frequency distribution table.

Janine inflated a ball to a radius of 18 cm and another ball to a radius of 12 cm.

Sladkaya [172]

Volume of a ball = (4/3)πr³

When r = 18cm, V = (4/3)×3.14×18³ =24416.64 cm³
When r = 12cm, V = (4/3)×3.14×12³ =7234.56 cm³
Difference = 24416.64 - 7234.56 = 17182.08 cm³

the volume of air in the larger ball is 17182.08 cm³ greater than smaller ball

Yumi and Juan pick up litter along the highway at the same rate. Yumi picks up litter for 3 miles and takes two hours longer tha

Harlamova29_29 [7]

3/(x+2) = 2/x

multiply both fractions by x(x+2) to cancel out the bottoms

so it becomes 3x = 2x+4

ow subtract 2X from both sides and you get

x = 4

so it took Juan 4 hours

it took Yumi 2 hours more so 4+2 = 6 hours
