Question 5: True
Question 6: False
Question 7: 23.32
Question 8: 6.73
Add them all up then divide then by 4 you will get 19.75cm
Assuming ya mean

take derivitive
remember dy/dx e^x=e^x
also the chain rule
so

find where it equals 0


multiply both sides by e^x

divide both sides by 8

take ln of both sides


divide both sides by 9

x≈-1/5
f'(-1)<0
f'(0)>0
so it is increasing from x to infinity
the interval it is increasing on is
The value 8 is significantly different from the other four values. Thus, the median would be the most appropr. measure of the center of this data distribution. Rearranging the data in ascending order:
8, 29, 31, 32, 33
The median is the middle value; it is 31.
Dividing b 8 is same as mutiiplying by 1/8
144=80+64
1/8(80+64)=1/8(80)+1/8(64)=10+8=18
