3) Six teams are playing in a baseball tournament. In how many ways can the teams be crowned champion and
runner-up?
Answer:
15ways
Step-by-step explanation:
This question bothers combination
Combination has to do with selection
Given
Total number of teams = 6
champion and runner up = 2
number of ways is expressed as 6C2
6C2 = 6!/(6-2)!2!
6C2 = 6!/4!2!
6C2 = 6*5*4!/4!*2
6c2 = 30/2
6C2 = 15
Hence the number of ways they can be selected is 15ways

1.6 + 3 x 4 - 2 divided by 2
An PEMDAS question, pretty easy!
Answer:
1.6+3 x 4 -2/2
1.6+12-2/2
1.6+12-1
13.6-1
12.6
hope this helps
have a good day :)
Step-by-step explanation:
The expression 1.6 + 3 x 4 - 2 divided by 2 simplifies to 12.6.
Use the concept of mathematical expression defined as:
Using operations like addition, subtraction, multiplication, and division, a mathematical expression is defined as a group of numerical variables and functions.
The given expression is:
1.6 + 3 x 4 - 2 divided by 2
We know the BODMAS rule,
According to this rule for a mathematical expression, we have to follow these operations in the following order:
1: Bracket opening
2: Division
3: Multiplication
4: Addition
5: Subtraction
Now applying this rule in the given expression,
1. 1.6 + 3 x 4 - 1
2. 1.6 + 12 - 1
3. 13.6 - 1
4. 12.6
Hence,
The expression 1.6 + 3 x 4 - 2 divided by 2 simplifies to 12.6.

What angles can make a triangle, it has to do with acute, right, and obtuse angles. which two of these three make a triangle?
Answer:
acute angles and an obtuse angle
Step-by-step explanation:
There are different types of triangle. We have;
Right angled
Obtuse triangle
isosceles triangle etc
Angles of an obtuse triangle is made up of two acute angles are an obtuse angle.
hence the two angles that can make up a triangle out of this three is acute angles and an obtuse angle since this two angles literally form an obtuse triangle

Can someone explain this question which part of the class do you think you will apply to your life both now or in the future?
i’m confused about #6, anyone know the answer?
Answer:
A
Step-by-step explanation:
Because B and D were both according to the Mean, and that is the same in the table so we can cross those out. And C is wrong because there are not less of a variation but more variation. So A would be your answer!

A coach purchases 47 hats for his players and their families at a total cost of $302. The cost of a small hat is $5.50. A medium hat costs $6.00. A large hat costs $7.00. He purchases three times as many medium hats as small hats. Using matrices, how many large hats did the coach purchase?
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.
Since a total of 47 hats where purchased, hence:
x + y + z = 47 (1)
Also, he spent a total of $302, hence:
5.5x + 6y + 7z = 302 (2)
He purchases three times as many medium hats as small hats, hence:
y = 3x
-x + 3y = 0 (3)
Represent equations 1, 2 and 3 in matrix form gives:
[tex]\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] =\left[\begin{array}{ccc}1&1&1\\5.5&6&7\\-3&1&0\end{array}\right] ^{-1} \left[\begin{array}{c}47\\302\\0\end{array}\right] \\\\\\ \left[\begin{array}{c}x\\y\\z\end{array}\right] = \left[\begin{array}{c}6\\18\\23\end{array}\right][/tex]
Therefore he purchases 6 small hats, 18 medium hats and 23 large hats
Answer:
Let x represent the number of small hat purchased, y represent the number of medium hat purchased and z represent the number of large hat purchased.
Since a total of 47 hats where purchased, hence:
x + y + z = 47 (1)
Also, he spent a total of $302, hence:
5.5x + 6y + 7z = 302 (2)
He purchases three times as many medium hats as small hats, hence:
y = 3x
-x + 3y = 0 (3)
Therefore he purchases 6 small hats, 18 medium hats and 23 large hats

If yu were to randomly survey 500 people each from two largest us cities would this be a random study why or why not HELP NEEDED ASAP !
Answer:
If you're timed then I would say,
Yes this is a random study because the problem specifically states that the survey samples were randomly selected from populations.
I think that is the answer! However, if you have time I would wait for another person to answer as well because I'm terrible at statistics :(
Answer:
No, its nat a random sample
Step-by-step explanation:
Its not a random sample because you have already selected two populations (the two largest US cities) which may or may not be representative of the vast majority of the country.

Step-by-step explanation:
. Joyce and Marianne both earn a combined income of $1,600 a week. Marianne earns $200 more than Joyce. How much income do Joyce and Marianne each earn?
( I need the equation and it needs to be solved. )
Answer:
So Joyce earns $700 and Marianne earns $900 per week. and $900=$200+$700. A slightly different approach is to say, if Marianne didn't earn 200 more than Joyce, then the combined income would be $200 less or $1600-$200=$1400. Now they both earn the same so each would get half of $1400 or $700.

Step-by-step explanation:
Property of the perpendicular lines,
If the two lines [tex]L_1[/tex] and [tex]L_2[/tex] having slopes [tex]m_1[/tex] and [tex]m_2[/tex] are perpendicular to each other,
Then [tex]m_1\times m_2=-1[/tex]
Equation of line [tex]L_1[/tex] → y = 3x + 5 ------(1)
Equation of line [tex]L_2[/tex] → 6y + 2x = 1 ------- (2)
Slope of line [tex]L_1[/tex],
[tex]m_1=3[/tex]
Slope of line [tex]L_2[/tex],
6y + 2x = 1
6y = -2x + 1
[tex]y=-\frac{2}{6}x+\frac{1}{6}[/tex]
[tex]y=-\frac{1}{3}x+\frac{1}{6}[/tex]
Therefore, [tex]m_2=-\frac{1}{3}[/tex]
By using the property of perpendicular lines,
[tex]m_1\times m_2=3\times (-\frac{1}{3} )[/tex]
[tex]=-1[/tex]
Therefore, both the lines are perpendicular.

How many blue pens were there to start with?
Answer:
180 blue 70 red
Step-by-step explanation:
b= blue r = red
b+r = 250
r = (250-b)
If 40% is removed the rest is 60%
If the 70% is removed the rest is 30%
0.6b + 0.3(250-b) = 129
0.6b + 75 - 0.3b = 129
0.3b = 54
divide by 0.3
b = 180
250-180 = 70
60% 0f 180 = 108
30% of 70 = 21
108 +21 = 129
