Step-by-step explanation:
The sum of the three angles in a triangle must be
. Since this triangle has a right angle, we know that it is
°, so the sum of the remaining two angles must be
.
We can set up an equation for the two remaining angles to determine the value of
:




Answer:

Step-by-step explanation:
Using central Limit Theorem (CLT), The sum of 100 random variables;
is approximately normally distributed with
Y ~ N (100 ×
) = N ( 50,
)
The approximate probability that it will take this child over 55 seconds to complete spinning can be determined as follows;
N ( 50,
)




Using Chebyshev's inequality:

Let assume that X has a symmetric distribution:
Then:


where: (
)
