This is a Binomial Distribution
Probability is 20C16 (0.5)^16 0(0.5)^4
= 4845 * 0.5^20 = 0.00462 = 0.462%
You multiple 3.14 time the diameter
3.14*3
9.42
So,
For every 2 large notebooks Ann orders, she orders 1 small notebook.
This can be stated as a ratio: 2:1
Add up the units to find the value of each unit.
2 + 1 = 3
Divide 48 by 3 to get the unit value.
48/3 = 16
The unit value is 16.
The number of large notebooks Ann orders is 2(16):16
This is a 2:1 ratio.
Therefore, Ann ordered 32 large notebooks and 16 small notebooks.
Answer:
Friend is not correct.
Step-by-step explanation:
<em>The complete question with image is attached.</em>
We need to find the angle and the point (0.8), or the angle created between the two lines.
First we need to find slope (m) of both the lines.
The slope (m) is change in y coordinates divided by change in x coordinates. Or
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
<u>Slope of line above:</u>
![m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{8-16}{0-(-4)}\\m=-2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5Cm%3D%5Cfrac%7B8-16%7D%7B0-%28-4%29%7D%5C%5Cm%3D-2)
<u>Slope of below line:</u>
![m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{8-0}{0-(-4)}\\m=2](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%5C%5Cm%3D%5Cfrac%7B8-0%7D%7B0-%28-4%29%7D%5C%5Cm%3D2)
The formula to find angle between two lines is:
![\theta = Tan^{-1}(\frac{m_2-m_1}{1+m_1m_2})](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20Tan%5E%7B-1%7D%28%5Cfrac%7Bm_2-m_1%7D%7B1%2Bm_1m_2%7D%29)
Where m_1 = -2 and m_2 = 2
Plugging in the values, we get:
Angle = 53
Hence, your friend IS NOT correct.
