Answer:
the coordinates of the point of x and y is -1÷ 2 and -√3÷ 2
Step-by-step explanation:
The computation of the coordinates of the point is shown below:
The angle is
= 4π ÷ 3
The radius is 1 unit
Now
x = rcos, and y = rsin
Now
x = 1cos(4π ÷ 3) = -1÷ 2
y = 1sin(4π ÷ 3) = -√3÷ 2
hence, the corordinates of the point of x and y is -1÷ 2 and -√3÷ 2

Answer:
Option C is correct.
The value closest to the actual weight, in pounds of the backpack for the student who had 4 books in the backpack = 13
Step-by-step explanation:
The complete, correct question is presented in the attached image to this solution.
From the table, it is evident that
Intercept = 10.53
Slope = 0.53
Since, the residual plot is analysed with linear regression to obtain the linear relationship between actual weight of the backpack and the number of books in the backpack, the equation relating them must be
y = mx + c
where y = Actual weight of the backpack
m = slope obtained from the analysis = 0.53
x = number of books in the backpack
c = intercept obtained from the analysis = 10.53
So, the relationship is properly written as
y = 0.53x + 10.53
So, when the number of books in the backpack = 4, what is the actual weight of the backpack?
x = 4, y = ?
y = 0.53x + 10.53
y = (0.53×4) + 10 53 = 12.65
To the nearest whole number, 12.65 = 13
Hence, the value closest to the actual weight, in pounds of the backpack for the student who had 4 books in the backpack amongst the options = 13
Hope this Helps!!!
