Y2-y1 over x2-x1 or you can go onto the calculator and push list and put in the points and it will give you the answer of 68
Answer:
59
Step-by-step explanation:
3^3=27
2x27=54
27+54+5=59
14 = -(p-8)
Step 1 : Distribute the negative sign. This is equivalent to multiplying each term in the parenthesis by -1.
14 = -p+8
Step 2: Subtract 8 from each side to isolate the -p.
14 - 8 = -p +8 - 8
6 = -p
Step 3: Multiply everything by -1 to get what p is equivalent to.
6 * -1 = -p * -1
-6 = p
Which can be rewritten as
p = -6
The confidence interval goes from 235.18 to 269.72.
We first find the z-score associated with this confidence level:
1-0.95 = 0.05/2 = 0.025
Using a z-table (http://www.normaltable.com/ztable-righttailed.html) we see that the z-score associated with this is 1.96.
The formula for the confidence interval is:

,
where x is the sample mean, s is the sample standard deviation and n is the sample size. With our data, we have:

252.45-17.2725 = 235.1775 ≈ 235.18
252.45+17.2725 = 269.7225 ≈ 269.72
