Hey there! :)
Answer:
29/28.
Step-by-step explanation:
Starting with:
![\frac{1}{4} + \frac{2}{7} + \frac{1}{2} =](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%2B%20%5Cfrac%7B2%7D%7B7%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%3D)
Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:
![\frac{7}{28} + \frac{8}{28} + \frac{14}{28} =](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B28%7D%20%2B%20%5Cfrac%7B8%7D%7B28%7D%20%2B%20%5Cfrac%7B14%7D%7B28%7D%20%3D)
Add the fractions:
![\frac{7}{28} + \frac{8}{28} + \frac{14}{28} = \frac{29}{28}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B28%7D%20%2B%20%5Cfrac%7B8%7D%7B28%7D%20%2B%20%5Cfrac%7B14%7D%7B28%7D%20%3D%20%5Cfrac%7B29%7D%7B28%7D)
Therefore, the fractions sum up to 29/28.
Answer:
7837
Step-by-step explanation:
1000 + 6901 - 64 = ?
=7837
1.168 rounded off to nearest thousands = 1168
The outlier is 84 and if you removed the outlier from the mean it would decrease.
<span>The goal of writing a number in scientific notation is to have a decimal number, with one digit to theleft of the decmial point, followed by a × 10to some power.
</span><span>
To format your number in this way, we'll divide the 245,893 by 10, 2time(s), making it a 2.45.
We do this, because each division by 10 moves the decimal point to the left one digit.
But in order to keep our number the same number, we must have a × 102next to the 2.45.

So, the final answer is 2.45 × 10<span>2 (: Hope im right!</span></span>
