If you want to know the number that is equivalent to 0.05, you can calculate this using the following two steps:
0.05 equals to 5/100 <span>which simplifies to </span>1/20.
<span>
The result is 1/20.

The expression is 2t−1/4t. The amount of ore is 21 metric tons.
Answer:
all real numbers
Step-by-step explanation:
3x-8 = -x + 4(x-2)
distributive property:
3x - 8 = -x + 4x-8
Combine like terms:
(add 3x to both sides)
-8 = -8
That means that x can be any number, because in the end, x will be canceled out from the equation.

Using the hypergeometric distribution, it is found that there is a 0.0452 = 4.52% probability that this group of four students includes at least two of the top three geography students in the class.
The students are chosen without replacement, hence the <em>hypergeometric distribution</em> is used to solve this question.
<h3>What is the hypergeometric distribution formula?</h3>
The <em>formula </em>is:
The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
In this problem:
- There are 28 students in class, hence .
- Four people will be chosen at random, hence .
- The top three is composed by 3 people, hence .
The probability that this group of four students includes at least two of the top three geography students in the class is:
In which:
Then:
0.0452 = 4.52% probability that this group of four students includes at least two of the top three geography students in the class.

A. -2 6/7, -3/2, 2.25, 2 1/3
B. 10:00 AM and 4:00 PM
C. The biggest change was 2.25 to -2 6/7, or 4:00 AM to 10:00 AM
D. I'm not sure what part C is referring to so I can't help with that one.
E. I believe it will decrease since it tends to decrease as the day goes on and then increase once again. (that seems to be the pattern, at least)
