The 'seconds' hand on the watch goes all the way around in 1 minute. <span>15 seconds is 1/4 of a complete 1-minute revolution. </span>So, the 2 cm is 1/4 of the way around the circle that the tip makes. This makes the full circumference of the circle 8cm.
<span>The length of the second hand will be the radius of the circle. Use the following equation: </span>
2 pi radius = circumference
Since we know the circumference, plug that in, and solve for the radius:
2 pi radius = 8 cm
radius = 8cm / 2 pi =<span> 1.27 cm</span>
we know that
normal distributions:
a function that represents the distribution of many random variables as a symmetrical bell-shaped graph
It is a very common continuous probability distribution
we know that
heights of students in any class is continuous
because it can be any real numbers
so, option-A..........Answer
Answer: 10511
The reason being you need to convert 63% to a decimal which would be 0.63
Then you would multiply 0.63 * 16684
And then you would get 10510.92 but you would up because you cannot have .9 of a fan
