Answer:
![Average = 43.29](https://tex.z-dn.net/?f=Average%20%3D%2043.29)
Step-by-step explanation:
Given
Time: 44.64,43.45,42.79 and 42.28
<em></em>
Required
Determine the average time
Average or mean is calculated as thus;
![Mean = \frac{\sum x}{n}](https://tex.z-dn.net/?f=Mean%20%3D%20%5Cfrac%7B%5Csum%20x%7D%7Bn%7D)
Where
= sum of observation
n = number of observation = 4
![Average = \frac{44.64 + 43.45 + 42.79 + 42.28}{4}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7B44.64%20%2B%2043.45%20%2B%2042.79%20%2B%2042.28%7D%7B4%7D)
![Average = \frac{173.16}{4}](https://tex.z-dn.net/?f=Average%20%3D%20%5Cfrac%7B173.16%7D%7B4%7D)
![Average = 43.29](https://tex.z-dn.net/?f=Average%20%3D%2043.29)
<em>Hence, the average time is 43.29</em>
Answer:
The translation is 2x-7
Step-by-step explanation:
Here, we want to write the given statement in an algebraic form
Let the number be x
2 times the number is 2 * x = 2x
Difference between this and 7 will be 2x-7
If x=mx-3 (which is not clear from your input),
3
then x-mx = -3, or mx-1x = 3, and x(m-1) = 3, and so x = ---------
m-1
