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.

Eighteen less than three times a number is twice the number. Write and solve
goblinko [34]

Answer:

The number is 18

Step-by-step explanation:

You can write an equation to represent this. Let x represent the unknown number.

3x - 18 = 2x

Move 2x to the left side. Remember, "change the side, change the sign." Add 0 as a placeholder to the right of the equals sign.

3x - 2x - 18 = 0

Simplify like terms.

x - 18 = 0

Move -18 to the right of the equals sign.

x = 18

Now that we know x = 18, we can substitute it into the problem.

"Eighteen less than three times 18 is two times 18."

18 x 3 = 54

54 - 18 = 36

36 is, in fact, two times 18. We can check this by dividing 36 by 2.

36 ÷ 2 = 18

The low temperature last week in Iceland was-2.25. The low temperature this week was 1.25. What was the change in temperature fr
viktelen [127]

Answer:

The change in temperature from last week to this week=3.5

Step-by-step explanation:

To get the change in temperature from last week to this week, we need to take last week's temperature and subtract it from this week's temperature.

For example;

Change in temperature=This week's temperature-last week's temperature

where;

This week's temperature=-2.25

last week's temperature=1.25

replacing;

Change in temperature=(1.25)-(-2.25)=1.25+2.25=3.5

The change in temperature from last week to this week=3.5
