Answer:
Step-by-step explanation:
-7t +1 = 56
-1. -1
-7t= 55
t = - ![\frac{55}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B55%7D%7B7%7D)
Since 19 is 76% of 25, we can assume that 76% of the people in the restaurant like the new menu. 76% of 227 is roughly 173. So about 173 people liked the menu that day. Hope this helps :)
Answer:
The width of the rectangular space = 3/2 miles .
Step-by-step explanation:
The area of the rectangular space = 1/2 sq miles.
The length of the rectangular space = 1/3 miles
The width of the rectangular space = k miles
Now, AREA OF THE RECTANGLE = LENGTH x WIDTH
⇒ ![\frac{1}{2} = \frac{1}{3} \times k\\\implies k = \frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%20%5Ctimes%20k%5C%5C%5Cimplies%20%20k%20%3D%20%5Cfrac%7B3%7D%7B2%7D)
or, k = 3/2 miles
Hence the width of the rectangular space = 3/2 miles
Answer:
![Mean = 4.35](https://tex.z-dn.net/?f=Mean%20%3D%204.35)
![SD = 0.5655](https://tex.z-dn.net/?f=SD%20%3D%200.5655)
Step-by-step explanation:
Given
![n = 5](https://tex.z-dn.net/?f=n%20%3D%205)
![p = 0.87](https://tex.z-dn.net/?f=p%20%3D%200.87)
Solving (a): Mean
![Mean = np](https://tex.z-dn.net/?f=Mean%20%3D%20np)
![Mean = 5 * 0.87](https://tex.z-dn.net/?f=Mean%20%3D%205%20%2A%200.87)
![Mean = 4.35](https://tex.z-dn.net/?f=Mean%20%3D%204.35)
Solving (b): Standard Deviation (SD)
![SD = np(1 - p)](https://tex.z-dn.net/?f=SD%20%3D%20np%281%20-%20p%29)
![SD = 5 * 0.87(1 - 0.87)](https://tex.z-dn.net/?f=SD%20%3D%205%20%2A%200.87%281%20-%200.87%29)
![SD = 5 * 0.87 * 0.13](https://tex.z-dn.net/?f=SD%20%3D%205%20%2A%200.87%20%2A%200.13)
![SD = 0.5655](https://tex.z-dn.net/?f=SD%20%3D%200.5655)
