Answer:
The mean will be increased by 5
Step-by-step explanation:
Suppose a set of data ![(2, 4, 6, 8, 10, 12)](https://tex.z-dn.net/?f=%282%2C%204%2C%206%2C%208%2C%2010%2C%2012%29)
Mean is defined as sum of all the values given set of data divided by total number of values.
Mean1 = ![\frac{2+4+6+8+10+12}{6} = \frac{42}{6} = 7](https://tex.z-dn.net/?f=%5Cfrac%7B2%2B4%2B6%2B8%2B10%2B12%7D%7B6%7D%20%3D%20%5Cfrac%7B42%7D%7B6%7D%20%3D%207)
Now if we add 5 toeach value, the new set becomes ![(7, 9, 11, 13, 15, 17)](https://tex.z-dn.net/?f=%287%2C%209%2C%2011%2C%2013%2C%2015%2C%2017%29)
for which,
Mean2 = ![\frac{7+9+11+13+15+17}{6} = \frac{72}{6} = 12](https://tex.z-dn.net/?f=%5Cfrac%7B7%2B9%2B11%2B13%2B15%2B17%7D%7B6%7D%20%3D%20%5Cfrac%7B72%7D%7B6%7D%20%3D%2012)
Mean2 - Mean1 = 5
Answer:Length: 27m
Step-by-step explanation:
- the formula of area of rectangle is : width*length
- so we just replace the values in the formula
- 162=6*Length
- Length=162/6
- Length=27m
$810 because if you use the simple interest formula (s=p*r*t), you get $810 hope this helped!
