Answer:
x = 32
Step-by-step explanation:
Each angle of the equilateral triangle is 60°.
(2x -4)° = 60°
x -2 = 30 . . . . . . divide by 2°
x = 32
__
5y° = 60°
y = 12 . . . . . . . . . divide by 5°
Answer:
X = 28
Step-by-step explanation:
The angle is 90 degrees in total and one portion of the angle is 62 degrees
You subtract the 62 degrees from the 90-degree angle to figure out the other unknown portion of the angle
90 - 62 = 28
So this is the answer:)))))
Answer:
m∠GDE
alternate interior angles
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: (
)
