Answer:
The correct answer is last option 78.5%
Step-by-step explanation:
Points to remember
Area of circle = πr²
Where r is the radius of circle
Area of square = a²
Where 'a' is the side length of square
<u>To find the area of circle</u>
Here r = 10 cinches
Area = πr²
= 3.14 * 10²
= 3.14 * 100 = 314
<u>To find the area of square</u>
Here a = 20 inches
Area = a²
= 20²
= 400
<u>To find the probability percentage</u>
Probability = area of circle/Area of square
= (314/400)*100
78.5 %
Answer:
I think it is -5+root-7/2 & -5-root-7/2
Step-by-step explanation:
Answer:
3
0st + 42t
Step-by-step explanation:
that's the answer, so i guess you can explain or are you good?
Since the distance is 3.667km and the time is 1/3 of an hour (20 minutes) we take the distance and divide it with time 3.667/20 thus the answer is
0.183 km/hr
Answer: The theoretical probability of the coin landing heads up is 0.7
Step-by-step explanation:
Hi, to answer this question we simply have to divide the number of times that the coin lands heads up (42 times) by the number of times that the coin was flipped:
Mathematically speaking:
42 /60 = 0.7 (decimal form)
The theoretical probability of the coin landing heads up is 0.7
For the or percentage form we simply multiply the result by 100:
0.7 (100) = 70%
