Answer:
=
Step-by-step explanation:
{0}={} because 0 means that there is nothing and in null set too, there is no elements.
7^2 + 6^2 = h^2
49 + 36 = h^2
85 = h^2
√85 = h
h = 9.21m

Cereal A
10 ounces = $5.90
10/10 ounces = $5.90/10 .... divide both sides by 10
1 ounce = $0.59
1 ounce = 59 cents
----------
Cereal B
24 ounces = $6.48
24/24 ounces = $6.48/24 .... divide both sides by 24
1 ounce = $0.27
1 ounce = 27 cents
We see that Cereal B is the cheaper deal per ounce
---------
<h3>Answer: Cereal B is the better deal</h3>
Answer:
[34,54]
Step-by-step explanation:
-The empirical rule states that the 95% of the sampled observations will fall within two standard deviations of the mean for a normally distributed population.
Where:
- 68% is the first standard deviation
- 95% is the second standard deviation about the mean
- 99.7% is the 3rd standard deviation about the mean.
-Therefore. the middle 95% interval is calculated as:
![CI=\mu+2\sigma\\\\=44\pm 2(5)\\\\=44\pm 10\\\\=[34,54]](https://tex.z-dn.net/?f=CI%3D%5Cmu%2B2%5Csigma%5C%5C%5C%5C%3D44%5Cpm%202%285%29%5C%5C%5C%5C%3D44%5Cpm%2010%5C%5C%5C%5C%3D%5B34%2C54%5D)
Hence, the interval is [34,54]
