2960m It should be correct
Answer:
x - -5.78526086, -1.50769051, 2.29295138
Step-by-step explanation:
graph each side of the equation. the solution si the x-value of the point of intersection.
B and a
barry=b
a=older bro
a is 3 more than 3b
a=3+3b
sum is 28
a+b=28
3+3b+b=28
3+4b=28
minus 3 both sides
4b=25
divide both sides by 4
b=6.25
a=3+3b
a=3+3(6.25)
a=3+18.75
a=21.75
barry=6.25 years
21.75 years=older bro
Answer:
If I read it right I believe it's C.
Step-by-step explanation:
Answer:
The y-intercept for this equation makes no sense for this model.
Step-by-step explanation:
In this case, the explanatory variable x is the year when the observations were taken. So, the values are the integer numbers between (and including) 1975 and 1986.
The<em> y-intercept for the equation of the linear regression makes no sense for this prediction</em>, for it would correspond to the value x=0 (the year 0) is not consider in the range of the explanatory data.
