Answer:
Area of segment = 9.8 cm² (Approx.)
Step-by-step explanation:
Given:
Angle θ = 120°
Radius of circle = 4 cm
Find:
Area of segment
Computation:
Area of segment = [θ/360][π][r]² - [1/2][r²][sinθ]
Area of segment = [120/360][3.14][4]² - [1/2][4²][sin120]
Area of segment = [0.333][3.14][16] - [0.5][16][0.866]
Area of segment = 16.7299 - 6.28
Area of segment = 9.8019
Area of segment = 9.8 cm² (Approx.)
Answer:
n = 1.92
Step-by-step explanation:
Multiply both sides of the equation by 3.2

Simplify both sides of the equation.
n = 1.92

Answer: There is probability of 0.367 that there will be no breakdown on his car in the trip.
Step-by-step explanation:
Since we have given that
Mean (λ) = 0.5 breakdown per week
Number of weeks the owner of the car is planning to have a trip on his car for = 2 weeks
So, mean for 2 weeks would be

We need to find the probability that there will be no breakdown on his car in the trip.
Probability that there will be no breakdown on his car in the trip is given by
P(X=0) is given by

Hence, there is probability of 0.367 that there will be no breakdown on his car in the trip.
Answer:
61/12a
Step-by-step explanation:
convert the mixed number 4 1/4 into a improper fraction which turns into 17/4, you then add the sum of 5/6a + 17/4a which is 61/12a
