Answer:
4 games played = 1/56
5 games played = 5/56
6 games played = 15/56
7 games played = 35/56
Step-by-step explanation:
The probability of each time winning is 0.5
So there are a couple of ways the series could go.
- Team A could win all first 4 matches. We can depict this as A-A-A-A
- Team A could win 4, while having lost 1. Lets depict this a A-B-A-A-A
- Team A could win 4, while having lost 2. A-B-B-A-A-A
- Team A could win 4, while having lost 3. A-B-B-B-A-A-A
These 4 possibilities could be repeated with B winning as well. It should be noted that these are the only ways for the series to end. We find the number of permutations of each possibility above to find their probability.
I advise you to study 'how to permute identical objects' for this.
These permutations are stated below:
1. 4!/4! = 1
2. 
= 5
3 
= 15
4 
= 35
These are they ways A or B could win. The total is 1+5+15+35 = 56. The answer given thus reflects the possibilities.
Question:
Is every whole number a natural number?
Types of Numbers:
In mathematics, there are a plethora of types of numbers, such as real numbers, rational numbers, integers, whole numbers, or natural numbers. Some of these types of numbers can be classified as other types of numbers, while others cannot. We can use the definitions of the different types of numbers to determine if one type is also another type.
Answer and Explanation:
Every whole number is a natural number with one exception, and that is the whole number 0. In other words, all whole numbers are natural numbers except the number 0.
The whole numbers and the natural numbers are defined as follows:
Whole Numbers: All of the positive integers, or the counting numbers, along with the number 0.Natural Numbers: All of the positive integers, or the counting numbers.
Notice that the whole numbers can actually be defined as all of the natural numbers along with the number 0. This tells us that every whole number is a natural number except the number 0 because 0 is not included in the positive integers, or the counting numbers.
So I hope I helped!
Basically every single one is a whole number except the 0
Answer:
The answer is y = 4x - 1
Step-by-step explanation:
First find two points on the line.
I will be using (-1, -5) & (1, 3).
Using the formula for slope, substitute in the values and solve:
y2-y1/x2-x1(This is the formula)
3--5/1--1(When using this formula, if y1 or x1 are negative, make them positive.)
3+5/1+1 or 8/2; which simplifies into 4/1.
So, the slope is 4/1.
Now we use point-slope form:
y - y1 = m(x-x1)
1. Substitute in the values.
y--5 = 4/1(x--1)
2. Simplify and distribute.
y + 5 = 4/1x + 4
3. Subtract 5 from both sides.
y = 4/1x - 1
4. Simplify.
y = 4x - 1
Answer:
Step-by-step explanation:
Let m denotes the number of minutes of phone use in a month.
In plan a there is no monthly fee, but the customer pays 8 cents per minute of use.
Total cost of plan a = 
In Plan B the customer pays a monthly fee of $2.40 and then an additional 7 cents per minute of use.
Total cost of plan b = 
To find amount of monthly phone use for which plan a cost more than plan b, solve the inequality 
.
Q=U because S=T
