Answer:
D
Step-by-step explanation:
As we can observe from the answers the representation is about the pair of points. We can sort it out by excluding the wrong options.
Options B and C is incorrect because the place of x and y coordinate is given mistakenly for the point (1,2)
The option A is incorrect due to the same problem for the point (8,7)
The correct option is D.
Answer:
14 x 14 = 196
10 x 14 x 1/2(basically just dividing by 2) = 70
70 x 4(four sides of triangles) = 280
Now let's add the areas together:
196 + 280 = 476 cm^2 is your answer.
Answer:
1/3
Step-by-step explanation:
There are 6 total tracks
brahms 2/6=1/3
Answer:

And the real value for this case is y=14. The residual is defined as:

Replacing we got:

And the best answer would be:
-2
Step-by-step explanation:
For this case we know that the best fit line for the relationship between x and y is given by:

And we know that an individual in the dataset has a score of 10 on the x-variable and a score of 14 on the y-variable. So then we can find the estimated value like this:

And the real value for this case is y=14. The residual is defined as:

Replacing we got:

And the best answer would be:
-2
