Answer: Option C
Step-by-step explanation:
The arc length is calculated as
Then
We know that
If BC is the diameter of the circumference then the radius R is:
Now we convert the anglo from degrees to radians
Finally
Probability of the next six babies being a girl = (0.4810)^6 = 0.0124
Therefore probability of at least one boy in next six births = 1 - 0.0124
= 0.9876 Answer
Answer:
137/(36π) ft/s
Step-by-step explanation:
The rate of change of volume will be the product of the rate of change of radius and the area of the sphere. The area of the sphere is ...
A = 4πr² = 4π(6 ft)² = 144π ft²
Then the relationship above is ...
dV/dt = A·dr/dt
548 ft³/s = (144π ft²)·dr/dt
dr/dt = (548 ft³/s)/(144π ft²) = 137/(36π) ft/s ≈ 1.2113 ft/s
Answer:
$6
Step-by-step explanation:
Susan can easily figure the tip by the following procedure. 10% of the bill is the amount with the decimal point moved one place to the left, so is $4.00. 5% of the bill is half that, or $2.00.
15% of the bill is 10% + 5%, so is $4.00 +2.00 = $6.00. The tip will be $6.00.
