Celinda thought of 89.5 in parts, 80 + 9 + 0.5, and divided each part: 80 ÷ 10 = 8; 9 ÷ 10 = or 0.9; 0.5 ÷ 10 = 0.05. Then she a
Arlecino [84]

Answer:

Dividing each part into 10 and then summing the results up, is equivalent to dividing 89.5 into 10.  

Step-by-step explanation:

This example refers to the Distributive Property of the division, which is valid when the dividend is decomposed.

A simple example could be: 400 ÷ 10 = (200 ÷ 10) + (200 ÷ 10)

In the exposed example we know that 89.5 = 80 + 9 + 0.5.

  • <u>Option 1</u>

(80/10) + (9/10) + (0.5/10) =

8 + 0.9 + 0.05=

8.95

  • <u>Option 2</u>

89.5/10 = 8.95

Is 0.790 greater than or equal to 0.79?
dedylja [7]

It's the same vallue. If they were different, i could argue that 2.000 is greater than 2.00. Impossible, because 2 is equal to 2.

What is the range of the set of data this box-and-whisker plot represents? 10 12 13 14 15 16 17 18 19 20 10 8 3 6​
sesenic [268]

Answer:

The 2 box-and-whisker plot is the correct one.

Step-by-step explanation:

The first step you need to do is write the numbers from least to greatest.

5, 7, 8, 10, 13, 14, 17, 17, 21. 5 and 21 will be the end points.

To make the box we need to find the median first. All you have to do is pick the middle number and it is 13. That just leaves box-and-whisker plots 2 and 3.

To find the first and third quartile, you need to take the other numbers from 13 to the left (10+8+7+5) and add them up then divide by 4 to get 7.5 and that is the first quartile.

To find the third quartile, you will go from 13 to the right (14+17+17+21) and divide by 4 to get 17.25.  

This equals the 2nd box-and-whisker plot.
