Answer:
- 0.5379
Step-by-step explanation:
Given the data below :
(47, 8), (46, 10), (27, 10)
X:
47
46
27
Y:
8
10
10
Using the functionality of the correl() function in excel, which takes in the x and y values of a data. The value of correlation Coefficient (r) obtained is - 0.5379 which indicates that a fairly strong negative correlation exists between the x and y variables. As the the strength of correlation depends on how close the Coefficient is to 1 (strong) or 0 ( weak). Negative value indicates that an increase in the value of one variable leads to a decrease on the value of the other.

.25 its a quarter of 100!
Both the pies at first have 360* as their initial complete angles.
The Cherry Pie is cut into 6 parts equal and the angular width of each piece will be 360/6=60*...therefore, each piece is 60*.
the Apple Pie is cut into 8 parts and the angle of each piece would be 360/8=45*...therefore, each piece is 45*.
Now the angular difference between the pieces of the 2 pies is 60*-45* = 15*.
Therefore the Cherry pie's piece is 15* greater than the Apple pie's piece.
Answer:
Step-by-step explanation:
Let length = y width = x
y = 3x + 2
Perimeter = Sum of all sides (or sum of both lengths and both widths)
2y + 2x
2(3x + 2) + 2x
6x + 4 + 2x
8x + 4
