B wpuld be (-1,3), H would be (-4,4), and D would be (-4,-1). Hope this helps and please give Brainliest!
Answer:
374.4
Step-by-step explanation:
All items related to the maintenance are 20% more expensive, it means that each datum is 20% bigger including the average.
The variance its a dispersion measurof the data and its calculated of this way:
Here n is the number of data, is the average and represent each datum. The increment in 20% in each parameter can be represented multiplying for 1.2, of this way
Factorizing the 1.2 we have:
That is:
The new variance is
I would use the distance formula to solve this problem:
Distance formula:
(x1,y1) = (3,5)
(x2,y2)= (0,1)
Plug in points to find radius:
r=
r=
r=
r=
r=
r=
r= 5 units
To find the other point on the circle that crosses the y-axis change the sign of y2.
(x1,y1) = (3,5)
(x2,y2) = (0,-1)
Fat percentage = Fat weight / Body weight * 100
Assuming that 3/2x^2 is (3/2)x^2
Fat percentage =
