Four soccer teams compete in a tournament. Each team faced each other exactly once with no ties allowed. A team received 1 point for each win.
The results
Team 1 had 1 point
Team 2 had 3 points
Team 3 had 1 point
How many points did team 4 have?
Answer:
1 point
Step-by-step explanation:
The number of games in the tournament is:
₄C₂ = 6
Another way to look at it: Team 1 plays 3 games against Team 2, 3, and 4. Then, Team 2 plays 2 games against Team 3 and 4 (Team 2 already played Team 1). Finally, Team 3 plays a game against Team 4. So the total is 3 + 2 + 1 = 6.
If there's a total of 6 games, then there's a total of 6 points. So if x is the number of points Team 4 has:
x + 1 + 3 + 1 = 6
x + 5 = 6
x = 1
Team 4 has 1 point.

Step-by-step explanation:
87th term of 12,0,-12
Answer:
[tex]a_{87} = -1020[/tex]
Step-by-step explanation:
Given:
The given AP is.
12,0,-12,......
[tex]n=87[/tex]
The first term of an AP [tex]a=12[/tex]
Common difference [tex]d=0-12=-12[/tex]
We use the the formula for nth term of an AP.
[tex]a_{n} = a+(n-1)d[/tex]
for 87th term
[tex]a_{87} = 12+(87-1)(-12)[/tex]
[tex]a_{87} = 12+(86)(-12)[/tex]
[tex]a_{87} = 12+(-1032)[/tex]
[tex]a_{87} = 12-1032[/tex]
[tex]a_{87} = -1020[/tex]

negative numbers, the product's sign will be
a) Positive; Negative
b) Negative; Negative
c) Positive; Positive
d) Negative; Positive
on will be. If you multiply six
Answer:
Step-by-step explanation:
Explanation:
The product of two positive numbers is always positive.
So product of All positive numbers will be always positive.
For Example
( + ) × ( + ) = ( + )
The product of two negative number is always positive.
So product of even negative numbers will be always positive
For example
( - ) × ( - ) = ( + )
Also product of negative and positive is also given as a negative
( - ) × ( + ) = ( - )
and
( + ) × ( - ) = ( - )
Let the Six Positive numbers be
a, b ,c , d, e, f
So the Product of Six Positive numbers will be
[tex](+a)\times (+b)\times (+c)\times (+d)\times (+e)\times (+f)=\textrm{Positive Number}[/tex]
Let the Six Negative numbers be
-a, -b ,-c , -d, -e, -f
So the Product of Six Negative numbers will be
[tex](-a)\times (-b)\times (-c)\times (-d)\times (-e)\times (-f)=\textrm{Positive Number}[/tex]
Therefore the Product's Sign will be
a) Positive ; Positive
Answer:
c) Positive; Positive
Step-by-step explanation:
As we know it is a basic rule in mathematics, that if positive is multiplied by positive it gives a positive result always. So hence, from this rule it is proved that if we multiply 6 positive numbers, we will be getting the product which will be having positive sign. And in the second part of the questions, answer is that if we multiply 6 negative numbers then the sign remains positive as we know it is also a basic rule in mathematics that when 2 negative numbers are multiplied by each and other then it will give a positive product. So the answer will remain 'c) Positive; Positive''
What is the remainder when 4x^3+2x^2-18+38/x-3
Answer:
110
Step-by-step explanation:
You want the remainder from the division ...
[tex]\dfrac{4x^3+2x^2-18x+38}{x-3}[/tex]
RemainderThe remainder theorem tells you the remainder of ...
f(x)/(x -a)
is f(a).
We can compute f(a) directly, or we can do it using synthetic division. The attachment shows the synthetic division approach.
If we want to evaluate f(x), it is convenient to write it in Horner Form:
f(x) = 4x³ +2x² -18x +38 = ((4x +2)x -18)x +38
Then, for x = 3, this is ...
((4·3 +2)·3 -18)·3 +38 = (14·3 -18)·3 +38 = 24·3 +38 = 110
The remainder from the division is 110.
S4) The data can be modeled by the regression line y = 1.2x + 3.5. What is the residual at

The residual is 1.5
Step-by-step explanation:
Given the regression line equation as : y=1.2x +3.5
The formula for residual = Observed y-value - Predicted y-value
This gives the vertical distance from the actual plotted point to the point on the regression line. You should find how far the data fall from the regression line.
In this case, at y=5, from the graph, to get the vertical distance, perform subtraction as;

Step-by-step explanation:

The average precipitation per month is :
65,52 inches ÷ 12 = 5,46 inches per months
HOPE THIS HELPED ;3
The predicted amount of precipitation received between the end of March and the end of June is 0 inches.
Explanation:To predict the amount of precipitation received between the end of March and the end of June, we need to find the difference in total precipitation between those two months. According to the given information, the total precipitation in inches for each month is as follows:
March: 4 inches
April: 2 inches
May: 0 inches
June: 4 inches
To find the amount of precipitation received between the end of March and the end of June, we can subtract the total precipitation at the end of March from the total precipitation at the end of June:
Total precipitation at the end of June - Total precipitation at the end of March = 4 inches - 4 inches = 0 inches
Therefore, the predicted amount of precipitation received between the end of March and the end of June is 0 inches.

A square has an area of 44.89in^2. How do you get the length of the diagonal of the square?
Answer:
[tex]6.7\sqrt{2}\ in[/tex]
Step-by-step explanation:
Let x inches be the length of the side of the square. The area of the square is
[tex]x\cdot x=x^2\ in^2[/tex]
Then
[tex]x^2=44.89\\ \\x=6.7\ in[/tex]
By the Pythagorean theorem,
[tex]d^2=6.7^2+6.7^2\\ \\d^2=44.89+44.89\\ \\d^2=89.78\\ \\d=\sqrt{89.78}=6.7\sqrt{2}\ in[/tex]
Find the length of a side by taking the square root of the area:
Side = sqrt44.89 = 6.7 inches.
Now to find the length of the diagonal multiply the side length by the sqrt of2:
Diagonal = 6.7Sqrt(2) ( exact length)

The perimeter of a square depends on the length of its sides. Answer the questions below regarding the relationship between the perimeter of the square and the length of one side of the square.
The perimeter of a square is calculated by multiplying the length of one side by 4.
The perimeter of a square is the sum of all four sides. Since a square has equal sides, you can find the perimeter by multiplying the length of one side by 4. The formula for the perimeter of a square is P=4s, where P is the perimeter and s is the length of one side.
For example, if the length of one side is 5 units, the perimeter would be 4 * 5 = 20 units. If the length of one side is 8 centimeters, the perimeter would be 4 * 8 = 32 centimeters.

the surface area of a cuboid is 95cm² and its lateral surface area is 63cm². find the area of its base
Answer:
The Area of the base is 16 cm² .
Step-by-step explanation:
Given as :
The surface area of the cuboid = x = 95 cm²
The lateral surface area of the cuboid = y = 63 cm²
Let The Area of the base = z cm²
Now, Let The length of cuboid = l cm
The breadth of cuboid = b cm
The height of cuboid = h cm
According to question
∵ The surface area of the cuboid = 2 ×(length × breadth + breadth × height + height × length)
Or, x = 2 ×(l × b + b × h + h × l)
Or, 95 = 2 ×(l × b + b × h + h × l)
Or, (l × b + b × h + h × l) = [tex]\dfrac{95}{2}[/tex] ....1
Similarly
∵lateral surface area of the cuboid = 2 ×(breadth × height + length × height)
Or, y = 2 ×(b × h + l × h)
Or, 2 ×(b × h + l × h) = 63
Or, (b × h + l × h) = [tex]\dfrac{63}{2}[/tex] ......2
Putting value of eq 2 into eq 1
so, (l × b + [tex]\dfrac{63}{2}[/tex] ) = [tex]\dfrac{95}{2}[/tex]
Or, l × b = [tex]\dfrac{95}{2}[/tex] - [tex]\dfrac{63}{2}[/tex]
Or, l × b = [tex]\dfrac{95 - 63}{2}[/tex]
i.e l × b = [tex]\dfrac{32}{2}[/tex]
so, l × b = 16
Now, Again
∵The Area of the base = ( length × breadth ) cm²
So, z = l × b
i.e z = 16 cm²
So, The Area of the base = z = 16 cm²
Hence,The Area of the base is 16 cm² . Answer
