Salutations!
<span>Last month Sarah Ryan and Taylor received a total of 882 emails. If Sarah receive 25% more emails than the sum of the numbers of emails received by Ryan and Taylor. How many emails did Sarah receive?
Lets solve this!
Let the sum of the number of email received by Ryan and Taylor be "x" and "y".
Sarah + Ryan + Taylor = 882 emails.
Sarah = 25/100 ( x+ 7)
Sarah = 25 + x + y/100 = 882
Now, isolate the numbers carefully ---
Sarah = 25 + x + y = 822 </span>× 100
Sarah = 25 + x + y = 82,200.
Sarah = x + y = 82,200 - 25
Sarah = x+ y = 82,175.
Sarah received 82,175 emails.
Hope I helped (:
Have a great day!
C knowing how to dissect a test and the questions
95.44% IQ scores are between 77 and 125
We're given,
Mean (a)=101
standard deviation (b)=12
To find : ![P[77 < x < 125]](https://tex.z-dn.net/?f=P%5B77%20%3C%20x%20%3C%20125%5D)
Using Empirical Rule:
∴
![P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\](https://tex.z-dn.net/?f=P%5B%5Cfrac%7B77-101%7D%7B12%7D%20%3C%20%5Cfrac%7Bx-a%7D%7Bb%7D%20%3C%20%5Cfrac%7B125-101%7D%7B12%7D%5D%5C%5C)
![=P[-2 < z < 2]\\](https://tex.z-dn.net/?f=%3DP%5B-2%20%3C%20z%20%3C%202%5D%5C%5C)
![=P[Z < 2]-P[Z < -2]\\](https://tex.z-dn.net/?f=%3DP%5BZ%20%3C%202%5D-P%5BZ%20%3C%20-2%5D%5C%5C)

Explanation:
The deeper you go in both Earth's interior and the swimming pool the greater the pressure grows. The difference is the swimming pool contains, mostly liquid and Earth's interior contains mostly solids.
