Answer:
probability to get exactly 2 heads when flipped a balanced coin 3 times is 3/8 = 0.375 (37.5%)
Step-by-step explanation:
Denoting H as head and T as tails , then in 3 flips there are 2³=8 possible outcomes.
the possible outcomes in 3 flips are
H , H , H
H , H , T
H , T , H
H , T , T
T , H , H
T , H , T
T , T , H
T , T , T
then there are 3 outcomes out of 8 where there are exactly 2 heads ( 2 heads with the tails in the 3 different places possible)
then the probability to get exactly 2 heads when flipped a balanced coin 3 times is 3/8 = 0.375 (37.5%)
Hi,
To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:

To find radius just divide diameter with 2.

Now just division:

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.
Hope this helps.

3.60
bc using a part to whole chart you cross multiply 24*15 get 360 then divide it by 100 and get 3.60
It is given in the question that,
George took a nonstop flight from Dallas to Los Angeles, a total flight distance of 1,233 miles. The plane flew at a speed of 460 miles per hour for the first 75 minutes of the flight and at a speed of 439 miles per hour for the remainder of the flight.
Let for x hours, the flight travelled with a speed of 439 miles per hour .
So we have,


And to convert it in minutes, we have to multiply by 60. And on doing so, we will get

I think you would multiply 20 × 4 and the answer would be 80 that the scientist counted the number of plants in each 4 sections after 20 days.
