Answer:
38.5 cm^2
Step-by-step explanation:
Area(shaded) = Area(large semicircle) - area(2 small equal semicircles)
= Area (large semicircle) - area (small circle)
= π(7)² x 1/2 - π(7/2)²
22/7 x 7 x 7 x 1/2 - 22/7 x 7/2 x 7/2
= 77 - 38.5
= 38.5 cm^2
Answer:
After calculating values from test statics we come to know that value of if null hypothesis is true then it will rejected
As critical values of z is ±1.96 after apply the test statics formula , we get the value of z that is - 4.50 As we consider the equation that
H₀ > z
Apply test statistic we fine the true value . So there is sufficient evidence to reject the claim.
Step-by-step explanation:
critical values z₀ = ±1.96; standardized test statistic z ≅ -4.50;
reject H₀
There is sufficient evidence to reject the claim.

Answer:
36
Step-by-step explanation:
Given
x² + 12x = 11
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 11 + 36
(x + 6)² = 47
