Answer:
C. 15.9 m
Step-by-step explanation:
Let x be the height of the telephone pole,
Since, the length of the shadow of pole is 34 m,
So, the ratio of the height of the pole and its shadow =
,
Also, the statue is of 36 cm tall casts a shadow 77 cm long,
Thus, the ratio of the height of pole = ![\frac{36}{77}](https://tex.z-dn.net/?f=%5Cfrac%7B36%7D%7B77%7D)
At the same time,
The ratio of height with shadow is same for all objects.
![\frac{x}{34}=\frac{36}{77}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B34%7D%3D%5Cfrac%7B36%7D%7B77%7D)
![x=\frac{34\times 36}{77}=\frac{1224}{77}=15.8961038961\approx 15.9](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B34%5Ctimes%2036%7D%7B77%7D%3D%5Cfrac%7B1224%7D%7B77%7D%3D15.8961038961%5Capprox%2015.9)
Hence, the height of the telephone pole is 15.9 m.
Option 'C' is correct.
Answer:
a. ![y= 130x + 350 + \epsilon](https://tex.z-dn.net/?f=y%3D%20130x%20%2B%20350%20%2B%20%5Cepsilon)
b. The symbol y-bar represents the average price of hotels in the area
Step-by-step explanation:
a. The regression line equation is given by:
![y=\alpha x + \beta + \epsilon](https://tex.z-dn.net/?f=y%3D%5Calpha%20x%20%2B%20%5Cbeta%20%2B%20%5Cepsilon)
Where Alpha represents the slope, Beta represents the intercept with the Y axis, and epsilon represents the random component of the model. Thus,
y
Obtaining:
.
b. In a simple linear regression model the value of y-bar represents the average of all values of y observed. Thus, since y represents the prices of the hotels, then y-bar is the average price of hotels in the area.
Step-by-step explanation:
soh cah toa
that is the saying I use
we will use cah
c is cos
a is ajacent
h is hypotinuse
to find cos K we need to do
adjacent / hypotenuse
can you do that and write it in the comments
