That depends on the shape
If the shape is a triangle, then the value of Y is 60
Could you provide a picture or better information so we can give you a complete answer?
Remark
Break them into small figures: triangle, square ( I presume), and a parallelogram.
Triangle
<u>Formula</u>
A = 1/2 * b * h
<u>Givens</u>
b = 7
h = 4
<u>Solve</u>
Area = 1/2 b*h = 1/2 * 7 * 4 = 14
Square
<u>Formula</u>
Area = s^2
<u>Solve</u>
s = 7
Area = 7^2 = 49
Parallelogram
<u>Formula</u>
A = b*h
<u>Givens</u>
b = 7
h = 3
<u>Solve</u>
Area = 7 * 3
Area = 21
Total Area
Total Area = triangle + Square + Parallelogram
Total Area = 14 + 49 + 21 = 84 square yards.
It is 17 because you go up by 17 everytime on the right sode of the table
Answer:
b) 65.08
ii) 0.75
Step-by-step explanation:
x(Kg): 62 63 64 65 66 67 68
Frequency(f): 1 5 11 15 10 6 2
xf: 62 315 704 975 660 402 136
b) mean(X) = ∑xf/N = 3254/50 = 65.08
c) x - X : -3.08 -2.08 -1.08 -0.08 0.92 1.92 2.92
(x - X)²: 9.49 4.33 1.17 0.0064 0.85 3.69 8.53
ii) Standard deviation(S.D.): √(∑(x - X)²/N = √(28.0664)/50 = √0.5613
∴ S.D.= 0.75
