Answer:
The value of the Rational expression when
is: 
Step-by-step explanation:
For this exercise is important to remember:
- When a negative number is raised to an even power, the result will be positive.
- The multiplication of signs:

Then, given the following Rational expression:

You need to follow these steps in order to find its value when
:
1. Substitute the given value of "x" (
) into the expression:

2. Evaluate and simplify:

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: (
)

<span>4 medium strawberries→</span><span> 48% of your daily recommend amount of vitamin c
x </span><span>medium strawberries→100% </span><span>of your daily recommend amount of vitamin c
4:48=x:100⇒48x=100*4
48x=400
x=8.33
8.33-4=4.33
4 and 1/3 of </span>medium strawberries you still need for your <span>your daily recommend amount of vitamin c.</span>
8/12 is left
3/4 is equivalent to 9/12 (multiply by 3)
9/12 minus 1/12 is 8/12
