The minute hand when moving is swiping a sector
The arc length is given 23.5 inch the angle swiped is 52 degree
we have to find radius
length of arc = 2pi r( theta )/360
23.5 = 2* 3.14 * r ( 52/360)
23.5 = r(0.907)
r= 23.5/ 0.907
r=25.90 inches Answer
Answer:

The answer is 120
Step-by-step explanation:
A triangle has 180 degrees in it total.
So all you have to do is 180 - 35 -25, and get your answer.
Answer: 10
Step-by-step explanation:
The formula used for standard error is :-
, where is population standard deviation and n is the sample size.
Given: n = 4
Then, the difference would expected between the sample mean and the population mean will be :
Hence, the expected difference between the sample mean and the population mean = 10
