Answer: 
Step-by-step explanation:
Given : Significance level : 
Sample size : n=85
Critical value : 
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :-

Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs = 
Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.
The independent will be the the size of the meal and the dependent will be the hunger level.
Answer: C
Step-by-step explanation:
Since y = 0 at x=3pi/2, we know that this is a cosine graph.
So to determine if its -cos or cosine, we can test the pt (0, 1).
Since cos(0)=1 whereas -cos(0)=-1, the answer is y=cos(x).
Given:
Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.
To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.
To find:
The number of ounces in each container of ginger ale.
Solution:
Let n be the number of ounces in each container of ginger ale.
According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,




Divide both sides by 2.

So, ginger required for punch is 45 ounces.
Number of containers = 3
Number of ounces in each container of ginger ale = n
Number of ounces in 3 containers of ginger ale = 3n
Now,

Divide both sides by 3.

Therefore, 15 ounces are in each container of ginger ale.
Answer:
I believe 1.) is x=y-4/2 and 2.) x=y-4/2 as well
Step-by-step explanation:
1.)
y=2x+4
-subtract 4 on both sides-
y-4=2x
-divide 2 on both sides-
x=y-4/2
2.)
y=2(x+2)
-distribute the 2-
y=2x+2
-subtract 2 on both sides-
y-2=2x
-divide 2 on both sides-
x=y-2/4
I dont know exactly if this is correct, but i hope it helps! :)
