Answer:
The probability is 0.28
Step-by-step explanation:
Here, we want to calculate the probability that the ball bearing randomly selected has a diameter greater then 4.4 mm
I.e P(X> 4.4)
P(X>4.4) = (4.75-4.4)/(4.75-3.5) = 0.35/1.25 = 0.28
228-12.50*2=x*10
228-25=10x
203=10x
Divide both sides by 10 and it is:
20.3=x
The price of each ticket is $20.30

Answer:
I think the answer is 2 and three
Answer:
Denote AH as height of triangle ABC, with H lies on BC.
Applying sine theorem:
AH/AC = sin 60
=> AH = AC x sin 60 = 47 x sqrt(3)/2 = 40.7
=> Area of triangle ABC is calculated by:
A = AH x BC x (1/2) = 40.7 x 30 x (1/2) = 610.5 = ~611
=> Option C is correct.
Hope this helps!
