Answer:
Option: D is the correct answer.
D.
Step-by-step explanation:
We are given set of data points as:
x y
50 10
30 11
11 5
35 9
50 12
20 3
90 7
By plotting all these point in a scatter plot we see that the equation that best fits the data is a curve or a parabola that opens down and attains it's maximum value and the equation as is obtained on the regression calculator is:
Answer:
B. Same distance and same direction
Step-by-step explanation:
The points have to move together while maintaining the same shape.
Answer:
See below.
Step-by-step explanation:
Variables:
L = length
W = width
P = perimeter
Equations:
L = W + 13
P = 2(L + W)
P = 2(W + 13 + W)
2(W + 13 + W) = 226
2(2W + 13) = 226
2W + 13 = 113
2W = 100
W = 50
L = W + 13 = 50 + 13 = 63
The length is 63 cm, and the width is 50 cm.
Answer:
Step-by-step explanation:
Diameter = 6 units
Radius = Diameter/2 = 6/2 = 3 units
Taking π=3.14
Circumference = 2(π)(r) = 2(3.14)(3) = 6(3.14) = 18.84 = c
c = 18.84
Area = π(r)^2 = π(3)^2 = 9π =9(3.14) = 28.26 = b
b = 28.26
So,
b + c = 28.26 + 18.84 = 47.1
