Answer:
Residual = Observed Value - Predicted Value
A residual plot is a graph that shows the residual values in the vertical axis and the independent variable or values of x in the horizontal axis. So the coordinates would be (x, corresponding residual of x)
The points in a residual plot of the data based on the table will be:
(1,-0.4)
(2,0,7)
(3,-0.2)
(4,-0.6)
Step-by-step explanation:
Answer:
300 balloons.
Step-by-step explanation:
Given:
210 balloons are filled for a reception this is 70% of the entire number balloons purchased.
Question asked:
Which equation can be used to find the total number of balloons purchased ?
<u>Solution:</u>
Let total number of balloons purchased = 
70% of the number of balloons purchased = 210

Therefore, total number balloons purchased was 300.
There is only 1 remaining side
We have 2 sides and an included angle, we use the Law of Cosines to solve the third side:
c^2 = a^2 + b^2 -2ab *cos(C)
c^2 = .5^2 + .333333333...^2 - 2 * .5 * .3333333... * cos (95)
c^2 = .25 + .1111111111111111... -2*.5*.3333333333...* -0.087156
c^2 = 0.3611111111 + 0.029052
c^2 = 0.3901631111
c = 0.6246303796
