Answer:

Step-by-step explanation:
Given

Required
Use R code to determine the regression equation

First, write the following code in a R program
~

Next, run the program
See attachment for program and output
From the output, go to coefficients:
Check Estimate Std. column, you have the following:



implies that:
Intercept


Hence, the least square regression equation is:
Answer:
He plowed 50 rows.
Step-by-step explanation:
Use proportions
1/4 = x/200
then cross multiply to find x.
4x=200
Divide both sides by 4
x= 50
He plowed 50 rows.
Answer:
y=30x^2+36x+48 OR f(x)=30x^2+36x+48
This is an exponential function/exponential graph. Hope I helped!
Step-by-step explanation:
Given: y=2(3x+6)(5x-4)
Use the distributive property!: y=(6x+12)(5x-4)
Use the distributive property!: y=(5x(6x+12)-4(6x+12))
Use the distributive property!: y=(30x^2+60x)-(24x+48)
Remove parenthesis: y=30x^2+60x-24x+48y=30x^2+36x+48 OR f(x)=30x^2+36x+48
This is an exponential function/exponential graph. Hope I helped!
Answer:
The answer is C. y= 4/5x -2
Step-by-step explanation:
y=mx+b
m is the slope or rise/run.
b is the y-intercept. You have to see where the line crosses at the y-axis.
Answer:
b
Step-by-step explanation:
Evaluate using the definition
n
= 
where n ! = n(n - 1)(n - 2)(n - 3)..... × 3 × 2 × 1
Given
