Write your answer as a fraction or whole number.

Answers

Answer 1

Answer:

1/6

Step-by-step explanation:

Firstly, Pr(e) = n(e)/Total outcome

Pr(2) = 1/3

Pr(1) = 1/2

Pr(1 and 2) = 1/3 * 1/2 = 1/6

Valley high school's football team played a total of 16 games. They won twice as many games as they lost. If they tied one game, how many games did the team won

Answers

Answer:

The team won 10 games.

Step-by-step explanation:

The statement indicates  that the football team played a total of 16 games, which means that  the total number of games they won, lost or tied is equal to 16 and you can express this as:

x+y+z=16, where:

x is the number of games the team won

y is the number of games the team lost

z is the number of games the team tied

As you know that they tied one game, it means that z=1:

x+y+1=16

x+y=16-1

x+y=15

Also, the statement says that they won twice as many games as they lost which means that the number of games they won is equal to two times the number of games they lost, which is:

x=2y

Now, you can replace x=2y in x+y=15 and solve for y:

2y+y=15

3y=15

y=15/3

y=5

Finally, you can replace the value of y in x=2y in order to find the value of x:

x=2(5)

x=10

According to this, the answer is that the team won 10 games.

What are Polynomials?

Polynomials are sums of k-xⁿ terms, where k can be any number and n can be any positive integer.

here we have this:

Considering the provided mathematical operation, we are going to identify wich is the correct statement, so we obtain the following:

Since the remainder is zero, it means that setting the divisor and quotient equal to zero gives us the roots, then we have:

2x-1=0

2x=1

x=1/2

and, we have,

x+5=0

x=-5

Finally we obtain that the roots are 1/2 and -5, then the correct answer is the option C.

Hence, The solution is , O c. 1/2 must be a root of the polynomial

2x² +9x-5.

#SPJ7

3a-2b=14. 3a+2b=28
..​

Answers

Answer:

a = 7

b = 3 1/2

Step-by-step explanation:

if you add the equations together then the 'b' will zero out

6a = 42

a = 7

substitute 7 for 'a' to solve for 'b'

3(7) - 2b = 14

21 - 2b = 14

-2b = -7

b = 7/2 or 3 1/2

Whats the difference between a subset and a proper subset? {5,8} {2,5,8} Is {5,8} a subset of {2,5,8}.

Answers

Answer:

[tex]\{5,8\}[/tex] is a subset of [tex]\{2,5,8\}[/tex]

Step-by-step explanation:

Required

Difference between subset and proper subset

To answer this question, I will use the following illustration.

[tex]A = \{1,2,3\}[/tex]

[tex]B = \{2,3\}[/tex]

[tex]C = \{1,2,3\}[/tex]

In the above sets, set B is a proper subset of set A because all elements of B can be found in A, but not element of A can be found in B.

Set C is a subset of A because [tex]A = C[/tex]

Using the above illustration, we have:

[tex]\{5,8\}[/tex] and [tex]\{2,5,8\}[/tex]

[tex]\{5,8\}[/tex] is a subset of [tex]\{2,5,8\}[/tex], because 5 and 8 are in [tex]\{2,5,8\}[/tex] but 2 which ca be found in [tex]\{2,5,8\}[/tex] is not in [tex]\{5,8\}[/tex]

Find the equation of a line that passes through the points (1,-5) and (3,-6).
Leave your answer in the form y =mx+c

Answers

Answer:

y = - [tex]\frac{1}{2}[/tex] x - [tex]\frac{9}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 5) and (x₂, y₂ ) = (3, - 6)

m = [tex]\frac{-6+5}{3=2}[/tex] = - [tex]\frac{1}{2}[/tex] , then

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (1, - 5 ) , then

- 5 = - [tex]\frac{1}{2}[/tex] + c ⇒ c = - 5 + [tex]\frac{1}{2}[/tex] = - [tex]\frac{9}{2}[/tex]

y = - [tex]\frac{1}{2}[/tex] x - [tex]\frac{9}{2}[/tex] ← equation of line
