Answer:
The confidence interval for the true mean calorie content is

Step-by-step explanation:
In this problem we know the mean and standard deviation fo the sample, so we can compute the CI like this:

We need to determine t for 10-1=9 degrees of freedom and 99% confidence level. We look up in the t-table and the value for t is 3.2498.
Then we can calculate the limits of the CI:

Hello there!
Let's use foil.
First: 4x * 2x = 8x^2
Outside: 4x * -9 = -36x
Inside: -7 * 2x = -14x
Last: -7 * -9 = 63
Now, let's combine these.
8x^2 - 36x - 14x + 63
Finally, we can simplify this
8x - 50x + 63
I hope I helped!

Answer:
The answer is: v < -3. So any number less than -3 fulfills the inequality.
Step-by-step explanation:
4 + 4(v - 6) < -29 + v
4 + 4v - 24 < -29 + v
4v - 20 < -29 + v
3v < -9
v < -3
Hope this helps! Have an awesome day! :-)
