FIND THE VOLUME OF THE COMPOSITE FIGURE

Mathematics
1 answer:
Nikolay [14]3 years ago
5 0

Answer:

836 cubic centimeters

Step-by-step explanation:

We need to add together the volumes of the three cubes.

Vcube = s*s*s

<u>Small cube:</u> V = 2^3 = 8

<u>Medium cube:</u> V = 7^3 = 343

<u>Large cube:</u> V = 8^3 = 512

Total volume: 8 + 343 + 512 = <u>836 cubic centimeters</u>

The given percentage scores are:

80 , 92 , 91 , 75 , 89 , 84 , 0 , 85

A. Calculate the average

So, the average = (sum of the scores)/(number of the scores)

Sum of the scores = 80 + 92 + 91 + 75 + 89 + 84 + 0 + 85 = 596

The number of the scores = 8

So,

The average = 596/8 = 74.5%

Does the average score really represent her abilities ?

No, because there is outlier which is ( 0 ) which mean it may be absent this test

the other scores are within 75 and 92

Which mean the average is less than the reasonable minimum score

====================================================================

B. Brandee received 78% at the missed test

so, we will find the new mean:

The new sum of the scores = 80 + 92 + 91 + 75 + 89 + 84 + 78 + 85 = 674

The new mean = 674/8 = 84.25%

====================================================================

C. What different did 0% score make ?

So, 0% give us not accurate representation of the student abilities

Does this new mean represent her abilities accurately ?

Yes

evablogger [386]

Answer: this is the steps to working the problem and the answer is 54: 3% means 3 out of each 100. if you have 100 items, 3% is just 3. You need more than 100 times as many (you want 354), so x must be more than 100 * 100, right? 3% of 10.62 is less than 1, and the problem says there are 354 :-)
