Answer:
<u>y = 139 + x³ + 17 </u>
Step-by-step explanation:
The word "sum" means the amount resulting from addition in an equation. This means that we are adding all of these numbers together.
The word "product" means the amount resulting from multiplication in an equation, this means we need to find the product of a number multiplied by itself three times. Since we don't know what number it is, we can use the variable 'x'.
So, you would be adding 139, the product of x³, and 17, which would be written as y = 139 + x³ + 17.

What is your question supposed to be? It's just a bunch of gibberish.
answer:spot-less
Step-by-step explanation:
21.00 divided by 4 is 5.25 so you'd be payingmore at "no mess or stress dry"
Using confidence interval concepts, it is found that:
a) The point estimate is the sample mean.
b) The confidence interval is:
c) If $1411 is between the bounds of the interval yes, otherwise no.
--------------
- At item a, it asks to provide a point estimate for the population mean, which is the sample mean
--------------
Item b:
- In the spreadsheet, it is possible to find the <em>standard deviation for the sample</em>, thus, the t-distribution is used.
- The confidence interval will be given by:
In which:
- is the sample mean.
- T is the critical value, from the t-distribution, with a two-tailed area of and n-1 degrees of freedom.
- s is the standard deviation for the sample.
- n is the sample size.
--------------
Item c:
We have to check if 1411 is between and .
- If it is, the interval includes the National Average, otherwise, it does not.
