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: (
)
The inverse value of sin⁻¹(A) = Ф° , is sin(Ф) = A
sin(Ф°) = (-√3)/2 THAT MEANS Ф = -60° OR Ф = 300°
Answer: 125
Step-by-step explanation:
4/25 = 20/Y
Cross multiply to get the equation
4Y = 500
Divide both sides by 4
Y=125
Answer:
Step-by-step explanation:
X=4
4×4=16
Answer:
B: Step 2; 6x − 8 = 12 + 2x
Step-by-step explanation:
the student added 2 x 4 during the distributive property but you must multiply so you get 8 rather than 6.
