Answer:
yea its in the book
Step-by-step explanation:
Answer:
It would be D because X^2 is different from 3x you would just multiply X^2 by 1 and 3x by 1 to get x^2+3x
Answer:

Step-by-step explanation:
Given

Required
Integrate
We have:

Let

Differentiate

Make dx the subject

So, we have:



Express x^(10) as x^(5*2)

Rewrite as:

Recall that: 

Integrate

Substitute: 

Hence:

Using the z-distribution, it is found that the 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).
We are given the <em>standard deviation</em> for the population, which is why the <em>z-distribution </em>is used to solve this question.
The information given is:
- Sample mean of
.
- Population standard deviation of
.
- Sample size of
.
The confidence interval is:
The critical value, using a z-distribution calculator, for a <u>95% confidence interval</u> is z = 1.645, hence:


The 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).
