Mean: To find the mean, we need to add up all of our numbers and divide by the amount added. Adding 22, 20, 14, 22, 29, 20 gives us 127. Then, we divide by 6. This gives us 21.166… or 21.13 rounded.
Mode: The mode is the number that appears the most often. Our numbers are 22, 20, 14, 22, 29, and 20. 22 appears 2 times, 20 appears 2 times, 14 appears 1 time, and 28 appears 1 time. Therefore, the mode is 22 and 20.
Medium/median: I am assuming you meant median, the median is the middle number when the list is sorted from least to greatest. This means our list is 14, 20, 20, 22, 22, 29. We can find the median by crossing out the outer numbers and so on until we reach the middle. 14 and 29 are crossed out. 20 and 22 are crossed out. This gives us 22 as the median.
Range: The range is the difference between the greatest and the least number in our list. The greatest number in our list is 29. The number of the least value is 14. 29-14 is 15. 15 is our range.
Answer:
the scores on her last test is x (x > 0)
because on her last tests she scored 4 points lower than she did on her fifth test
=> the scores in the 5th test is x + 4
because Angela’s average for six math tests is 87, we have:
![\frac{93 + 87 + 82 + 86 + x + x + 4}{6} = 87 \\ \\ < = > \frac{352 + 2x}{6} = 87 \\ \\ < = > 352 + 2x = 522 \\ \\ < = > 2x = 170 \\ \\ < = > x = 85](https://tex.z-dn.net/?f=%20%5Cfrac%7B93%20%2B%2087%20%2B%2082%20%2B%2086%20%2B%20x%20%2B%20x%20%2B%204%7D%7B6%7D%20%3D%2087%20%5C%5C%20%20%5C%5C%20%20%3C%20%20%3D%20%20%3E%20%20%5Cfrac%7B352%20%2B%202x%7D%7B6%7D%20%20%20%3D%2087%20%5C%5C%20%20%5C%5C%20%20%3C%20%20%3D%20%20%3E%20352%20%2B%202x%20%3D%20522%20%5C%5C%20%20%5C%5C%20%20%3C%20%20%3D%20%20%3E%202x%20%3D%20170%20%5C%5C%20%20%5C%5C%20%20%3C%20%20%3D%20%20%3E%20x%20%3D%2085)
=> on her last test, she had 85
=> on her 5th test, she had 85 + 4 = 89
Answer:
It is the second answer
Step-by-step explanation:
The volume of <span>a right square pyramid is
![V= \frac{1}{3} A_{\text{ basis } }\cdot h](https://tex.z-dn.net/?f=V%3D%20%5Cfrac%7B1%7D%7B3%7D%20A_%7B%5Ctext%7B%20basis%20%7D%20%7D%5Ccdot%20h)
, where </span><span>
![A_{\text{ basis } }](https://tex.z-dn.net/?f=A_%7B%5Ctext%7B%20basis%20%7D%20%7D)
is basis area.
</span>
If the lengths of the sides of the base remain fixed and height
<span>is multiplied by a factor 10, than new height is
![H=10h](https://tex.z-dn.net/?f=H%3D10h)
and the volume is
</span>
