Answer:
ANSWER
a=-32
EXPLANATION
If C(a,1) is on the line that passes through A(3, 7), and B(-4, 9), then the three points are collinear.
This implies that, when we find the slope using any two points, we should get the same re. sorry couldnt finish
Step-by-step explanation:
U do 4/20 = p/100 then u cross multiply the 4 with 100 getting u 400, then divide the 400 by 20, giving u the answer of 20%
Answer:
W = 6t + 90
Step-by-step explanation:
Given :
Starting weight = intercept = 90 kg
Weight gained after 8 months = 138 kg
Using the slope intercept relation ;
We can obtain the rate of change, slope ;
y = mt + c
m = slope ; t = time after t months ; c = intercept
y = weight gained after 8 months
138 = 8m + 90
138 - 90 = 8m
48 = 8m
m = 48 / 8
m = 6
Hence, slope intercept equation equals :
W = 6t + 90
I would give the answer but there are to many numbers and I don't want you to get confused by the answer I give you
Answer:
b) y = 289.815 when ![x_1 = 180 \text{ and } x_2 = 310](https://tex.z-dn.net/?f=x_1%20%3D%20180%20%5Ctext%7B%20and%20%7D%20x_2%20%3D%20310)
Step-by-step explanation:
We are given the following information in the question:
![y = 29.1270 + 0.5906x_1 + 0.4980x_2](https://tex.z-dn.net/?f=y%20%3D%2029.1270%20%2B%200.5906x_1%20%2B%200.4980x_2)
where y is the dependent variable,
are the independent variable.
The multiple regression equation is of the form:
![y = b_0 + b_1x_1 + b_2x_2](https://tex.z-dn.net/?f=y%20%3D%20b_0%20%2B%20b_1x_1%20%2B%20b_2x_2)
where,
: is the intercept of the equation and is the value of dependent variable when all the independent variable are zero.
: It is the slope coefficient of the independent variable
.
: It is the slope coefficient of the independent variable
.
- The regression coefficient in multiple regression is the slope of the linear relationship between the dependent and the part of a predictor variable that is independent of all other predictor variables.
Comparing the equations, we get:
![b_1 = 0.5906\\b_2 = 0.4980](https://tex.z-dn.net/?f=b_1%20%3D%200.5906%5C%5Cb_2%20%3D%200.4980)
- This means holding
constant, a change of one in
is associated with a change of 0.5906 in the dependent variable.
- This means holding
constant, a change of 1 in
is associated with a change of 0.4980 in the dependent variable.
b) We have to estimate the value of y
![y = 29.1270 + 0.5906(180) + 0.4980(310) = 289.815](https://tex.z-dn.net/?f=y%20%3D%2029.1270%20%2B%200.5906%28180%29%20%2B%200.4980%28310%29%20%3D%20289.815)
