multiply 12 and 16 then multiply 8 and 10 then add them up to get 15,360
It should be $109 for the bike because if u divide 327 by 3 it equals 109.
15- 10 divided by 21- -9 should give you your slope
Answer:
−x^2−11
Step-by-step explanation:
Distribute the Negative Sign:
=−3x−4+−1(x^2−3x+7)
=−3x+−4+−1x^2+−1(−3x)+(−1)(7)
=−3x+−4+−x^2+3x+−7
Combine Like Terms:
=−3x+−4+−x^2+3x+−7
=(−x^2)+(−3x+3x)+(−4+−7)
=−x^2+−11
Answer:
The 99% confidence interval for the true mean number of Banana Bombs in 10.40 ounce packages is between 689.3 and 703.86.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
That is z with a pvalue of
, so Z = 2.575.
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 696.58 - 7.28 = 689.3 pieces
The upper end of the interval is the sample mean added to M. So it is 696.58 + 7.28 = 703.86 pieces
The 99% confidence interval for the true mean number of Banana Bombs in 10.40 ounce packages is between 689.3 and 703.86.
