klasskru [66]3 years ago
8 0

Answer:

Exact answer = 10.41666666666666666666666666666pi

Estimated answer = 32.70938

Step-by-step explanation:

Semi circle formula: 1/2 * 4/3 * pi * r^3

r = 2.5

1/2 * 4/3 * pi * 2.5^3

2/3 * pi * 2.5^3

2/3 * pi * 15.625

10.416..... * pi

Exact answer = 10.417pi

We can estimate pi as 3.14

So, 10.417 * 3.14 = 32.70938

Exact answer = 10.41666666666666666666666666666pi

Estimated answer = 32.70938

From the box plot, it can be seen that for grade 7 students,
The least value is 72 and the highest value is 91. The lower and the upper quartiles are 78 and 88 respectively while the median is 84.

Thus, interquatile range of <span>the resting pulse rate of grade 7 students is upper quatile - lower quartle = 88 - 78 = 10

</span>Similarly, from the box plot, it can be seen that for grade 8 students,
The least value is 76 and the highest value is 97. The lower and the upper quartiles are 85 and 94 respectively while the median is 89.

Thus, interquatile range of the resting pulse rate of grade 8 students is upper quatile - lower quartle = 94 - 85 = 9

The difference of the medians <span>of the resting pulse rate of grade 7 students and grade 8 students is 89 - 84 = 5

Therefore, t</span><span>he difference of the medians is about half of the interquartile range of either data set.</span>

-3 1/2 + ( -6 1/2) =<br> 5/8 - {-2/8} =<br> - 9/10 - 2/5 =<br> 6 3/5 - (-2 1/5)
marin [14]

Answer:

-3 1/2 + ( -6 1/2) =  -10

5/8 - {-2/8} =  7/8

- 9/10 - 2/5 =  -4

6 3/5 - (-2 1/5) = 44/5

Step-by-step explanation:

-3 1/2 + ( -6 1/2) =  <em>-7/2 + (-13/2) = -20/2 =</em><em><u> </u></em><em><u>-10</u></em>

5/8 - {-2/8} =  <em>5/8 + 2/8 = </em><u><em>7/8</em></u>

- 9/10 - 2/5 =  <em>-18-2/5 = -20/5 = </em><u><em>-4</em></u>

6 3/5 - (-2 1/5) = <em>33/5 + 11/5 = </em><em><u>44/5</u></em>
