keep your denominator the samem...ithink
Based on the given graph above, here are the answers for the following questions:
A. Based on the graph, there is only 1 cycle in it. It started at y=0 and ends in its starting point again which is still y=0.
B. This cycle is 2 units long so this means that the period of the graph is 2pi units long.
C. The amplitude is defined as the distance from the center to the peak of the valley in the graph. So basing on it, the amplitude would be 2.
Hope these answers help.
Answer:
Critical value is 1.318 and the confidence interval is 29.357 to 33.042
Step-by-step explanation:
n = 25
x = 31.2
s = 6.99
Degree of freedom = n-1= 25-1 =24
Confidence level = 0.8
So, α = 1- 0.8= 0.2
t critical = 
Formula of confidence interval :

Confidence interval :

Confidence interval : 
to 
Hence critical value is 1.318 and the confidence interval is 29.357 to 33.042
The answer seems to be the third option C = S + 4
Unit rate = 3/8 : 1/6
We can also write this as:
3/8 / 1/6
Flip the 2nd fraction and multiply:
3/8 * 6/1
Multiply the numerators and denominators together:
18/8
Simplify by dividing the numerator and denominaotr by 2:
18 / 2 = 9
8 / 2 = 4
So we have:
9/4
