Step-by-step explanation:
Area of Sector
= θ/360° * πr² (degrees) or 0.5r²θ (radians)
Question 11:
- (88°)/360° * π(19)² = 277.23ft².
Question 12:
- (260°)/360° * π(11)² = 274.54mi².
Question 13:
- 0.5(6.2)²(7π/12) = 35.22km².
Question 14:
- 0.5(7.1)²(5π/3) = 131.97cm².
Question 15:
- (215°)/360° * π(4.5)² = 37.99yd².
Question 16:
- 0.5(21.4)²(13π/18) = 519.54m².

y-1=2*(x+2)
Step-by-step explanation:
Answer: the probability that the person is between 65 and 69 inches is 0.54
Step-by-step explanation:
Since the height for Asian adult males is normally distributed, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = height for Asian adult males.
µ = mean height
σ = standard deviation
From the information given,
µ = 66 inches
σ = 2.5 inches
We want to find the probability that the person is between 65 and 69 inches. It is expressed as
P(65 ≤ x ≤ 69)
For x = 65
z = (65 - 66)/2.5 = - 0.4
Looking at the normal distribution table, the probability corresponding to the z score is 0.34
For x = 69
z = (69 - 66)/2.5 = 1.2
Looking at the normal distribution table, the probability corresponding to the z score is 0.88
Therefore,
P(65 ≤ x ≤ 69) = 0.88 - 0.34 = 0.54
