Answer:
80.0456<
<81.1210
Step-by-step explanation:
-Given the mean, 
and 
, the confidence interval can be calculated using the formula:
#We substitute our values in the formula to solve for CI:
![=\bar x\pm z\times \frac{\sigma}{\sqrt{n}}\\\\=\bar y\pm z_{0.05}\times \frac{s}{\sqrt{72}}\\\\=80.5833\pm 1.645\times \frac{2.77369}{\sqrt{72}}\\\\=80.5833\pm0.5377\\\\=[80.0456,81.1210]](https://tex.z-dn.net/?f=%3D%5Cbar%20x%5Cpm%20z%5Ctimes%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%3D%5Cbar%20y%5Cpm%20z_%7B0.05%7D%5Ctimes%20%5Cfrac%7Bs%7D%7B%5Csqrt%7B72%7D%7D%5C%5C%5C%5C%3D80.5833%5Cpm%201.645%5Ctimes%20%5Cfrac%7B2.77369%7D%7B%5Csqrt%7B72%7D%7D%5C%5C%5C%5C%3D80.5833%5Cpm0.5377%5C%5C%5C%5C%3D%5B80.0456%2C81.1210%5D)
Hence, the confidence interval lies between 80.0456 and 81.1210
Answer:
For the first 2 pages, you will want to count how many sides and angles for the stated figure above. Then you want to figure out what other figures that are related to the figure stated above. i.e. a square is a rectangle but not all rectangles are squares. On the last page you want to figure out what is the figure's name and other names that are related/same on the figure's original name. And lastly for part II you want to do the same thing for page 1 and 2, but instead you want to compare and contrast the 2 figures stated above. i.e. Parallelograms and Trapezoids.

Answer:
Step-by-step explanation:
<u>Number of people using more than one sport facility:</u>
- 38 - gym and pool
- 31 - pool and track
- 33 - gym and track
- 16 - all three
<u>Since 16 is counted for all three, total number of those using more than one facility is therefore:</u>
<u>Number of people using exactly one facility is:</u>
<u>Probability of the person using exactly one facility is:</u>
Answer:
<h2>x = 11°</h2>
Step-by-step explanation:
From the question the total angle here is 90° that means the angles are complementary.
Complementary angles are angles that add up to 90°
To find the value of x add the individual angles that's 
ZWY and XWY and equate it to
m XWZ that's 90°
So we have
ZWY + XWY = m XWZ
2x + 8 + 5x + 5 = 90
7x + 13 = 90
7x = 90 - 13
7x = 77
Divide both sides by 7
We have the final answer as
<h3>x = 11°</h3>
Hope this helps you
