Step-by-step explanation:
32/80=.4
Area of a circle = pi x r^2
Area of circle = 150,000/ 1578 = 95.06 square miles
95.06 = 3.14 x r ^2
Divide both sides by 3.14
R^2 = 30.27
Find the square root:
R = sqrt(30.27)
R = 5.5
The radius is c) 5.5 miles
Answer:
<u>$67.43 altogether</u>
Step-by-step explanation:
A 15% percent tip means 15% OF the bill.
15% of 58.65

You can't really pay $8.7975, so you would round to the nearest one hundredth which is $8.78.
Now you add the $8.78 to $58.65 which will give you $67.43.
I hope that helps!
Answer:
Incorrect.
Step-by-step explanation:
1 toss could not change the frequency by such a large margin 0.47 ---> 0.55.
The number of heads obtained in 30 tosses = 30 * 0.47 = 14.
So if the next toss came up heads the relative frequency of heads would be
15/31 = 0.48.
