Out of all the numbers from 1 to 80, there are (80-20)/(80) = 60/80 = 0.75
of them that are greater than 20 .
So every time you pick one at random, there a 75% chance that it will be
greater than 20.
If everything works out according to pefectly random probabilities, then
in 180 selections, 75% of them = (0.75 x 180) = <em>135 of the selections</em>
would be numbers greater than 20 .
2/3 = 0.6666666...... (I dont know how to put a bar above the 6)
3/11 = 0.27 (with a bar above the 27
8.4 (with a bar above the 4)
Answer:
1.2 lbs
Step-by-step explanation:
This problem is set up so that the total price is proportional to the price per pound, so to find the proportion you would divide the total cost by the cost per pound. 3.42/2.85 = 1.2, so the answer is 1.2 pounds.
The answer is 11.17 m. The formula for finding an arc length is y/360 (2piR) where y is the angle and R is the radius. 80/360 (2pi(8)) = 11.17
