Answer : The 5th day = 3 Celsius
Explanation:
the average of the first 4 day is 8
Which mean the combine temp on the first 4 day is 8 x 4 = 32
Now on the first 5 day the average temp is 7
Then the combine temp on the first 5 day is 7 x 5 = 35
Find the 5th day
4 days combine temp + 5th day = the combine temp of 5 days
32 + 5th day = 35
5th day = 35-32
5th day temp = 3C
False

i could be wrong but i’m 85% certain
Answer:
The number of cases prior to the increase is 50.
Step-by-step explanation:
It is given that the number of measles cases increased by 13.6% and the number of cases after increase is 57.
We need to find the number of cases prior to the increase.
Let x be the number of cases prior to the increase.
x + 13.6% of x = 57
![x+x\times \frac{13.6}{100}=57](https://tex.z-dn.net/?f=x%2Bx%5Ctimes%20%5Cfrac%7B13.6%7D%7B100%7D%3D57)
![x+0.136x=57](https://tex.z-dn.net/?f=x%2B0.136x%3D57)
![1.136x=57](https://tex.z-dn.net/?f=1.136x%3D57)
Divide both the sides by 1.136.
![\frac{1.136x}{1.136}=\frac{57}{1.136}](https://tex.z-dn.net/?f=%5Cfrac%7B1.136x%7D%7B1.136%7D%3D%5Cfrac%7B57%7D%7B1.136%7D)
![x=50.176](https://tex.z-dn.net/?f=x%3D50.176)
![x\approx 50](https://tex.z-dn.net/?f=x%5Capprox%2050)
Therefore the number of cases prior to the increase is 50.
