Answer:
central angle = 360/24 = 15°
arc length = 15/360 * 2π * 15 = 1.25π = 3.93 feet.
Area of a sector = 15/360 * π * (15)^2 = 9.375π = 29.45 square feet
Hope This Helps! Have A Nice Day!!

Answer:
P(A' ∩ B) = 0.12
Step-by-step explanation:
Given:
P(A) = 0.41, P(B) = 0.32 and P(B' ∩ A) = 0.21
To Find:
P(A' ∩ B)
Solution:
Since, P(B' ∩ A) = P(A) - P(A ∩ B)
By substituting the values given,
0.21 = 0.41 - P(A ∩ B)
P(A ∩ B) = 0.41 - 0.21
= 0.20
Since, P(A' ∩ B) = P(B) - P(A ∩ B)
P(A' ∩ B) = 0.32 - 0.20
= 0.12
Therefore, P(A' ∩ B) = 0.12 is the answer.
The answer is -1 , because when you add a negative number to a positive number the negative number will subtract , and vise versa.
