Answer:
See below.
Step-by-step explanation:
No odd number is divisible by 2 evenly. All of them leave a remainder of 0.5
For example 19/2 = 9.5
So the next 5 are 21 23 25 27 29
Answer:
Step-by-step explanation:
- Given that μ = 20seconds and SD-standard deviation = 5seconds
- To get the percentage of rats that took less than 10 seconds to finish is;
- P( X < 10) = P( z < x -μ/SD)
- = P( z< -2.00) = 0.028 = 2.28%
- Hence, 2.28% of the rats took less than 10seconds to finish

OOOKKKKK.........
We all know that a well is circular. So, First, lets find out the circumference of the wheel.
Given :
radius = 10 feet
π = 22 / 7
We know,
Circumference = 2πr
= 2 × (22 / 7) × 10
= 62.9 ft.
Now,
One revolution means the wheel has covered a distance equal to its circumference. So, 22 revolutions per minute means that the wheel is covering 22 times its circumference in 1 minute. So, Lets convert the revolution to feet.
Given,
The wheel is travelling at 22 revolutions per minute.
= 22 * Circumference per minute
= 22 * 62.9 ft. per minute
= 1383.8 ft. per minute
Now, that we know how much feet it is travelling in 1 minute, we can easily find how much it takes it to travel 10 feet.
Using unitary method,
The wheel travels 1383.8 ft. in 1 minute
The wheel travels 1383.8 ft. in 60 seconds.
The wheel travels 1 ft. in (60 / 1383.8) seconds.
The wheel travels 10 ft. in (60 / 1383.8) * 10 seconds.
= 0.4 seconds
So, the answer is 0.4 seconds. Of course...the answer is rounded!!
