Answer:
0.05547
Step-by-step explanation:
Given :
_____Peter __ Alan __ Sui__total
Before 1838 __ 418 ___1475 _3731
After _ 1420 __ 329 ___1140_2889
Total _3258 __ 747 __ 2615 _6620
The expected frequency = (Row total * column total) / N
N = grand total = 6620
Using calculator :
Expected values are :
1836.19 __ 421.006 __ 1473.8
1421.81 ___325.994__ 1141.2
χ² = Σ(Observed - Expected)² / Expected
χ² = (0.00177817 + 0.0214571 + 0.000974852 + 0.00229642 + 0.0277108 + 0.00125897)
χ² = 0.05547
That one correct so yes um cause the app said answer must be above 20 characters
Answer:
The volume of the cylinder V = 942 cm³
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the graph
The height of the cylinder (h) = 12cm
The diameter of the cylinder d = 10cm
The radius of the cylinder
d = 2r
r =
r = 5 cm
<u><em>Step(ii):-</em></u>
The Volume of the cylinder
V = π r² h
V = π (5)²(12)
V = 300π cubic centimeter
V = 300 × 3.14
V = 942 cm³
<u><em>Final answer:-</em></u>
Volume of the cylinder V = 942 cm³
Steps to solve:
1/2hb = d²
~Divide 1/2h to both sides
b = 2d²/h
Best of Luck!
