Answer:
Area=210
perimeter=66
Step-by-step explanation:
A=a+b(h)/2
P=a+b+c+d
Answer:
The regression line is not a good model because there is a pattern in the residual plot.
Step-by-step explanation:
Given is a residual plot for a data set
The residual plot shows scatter plot of x and y
The plotting of points show that there is not likely to be a linear trend of relation between the two variables. It is more likely to be parabolic or exponential.
Hence the regression line cannot be a good model as they do not approach 0.
Also there is not a pattern of linear trend.
D) The regression line is not a good model because there is a pattern in the residual plot.
Answer:
b-14 = 9
b = 23
Step-by-step explanation:
Add 14 to 9 to get b alone.
The value of a is D)73 I think because 180-107 since a straight line is 180 u just subtract the angle from it. hope this helps.
Answer:
b)
Step-by-step explanation:
b) set up equations so they are equal to each other,
this is when f(x)=g(x) so our approximation was close.
c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
