Answer:

The difference between a relation and a function is that a relationship can have many outputs for a single input, but a function has a single input for a single output. This is the basic factor to differentiate between relation and function. Relations are used, so those model concepts are formed.

Answer:

3 1/5

Step-by-step explanation:

8/1 = 8

8/1 * 2/5 = 16/5

16/5 = 3 1/5

Answer:

32/10, or 3 1/5

Step-by-step explanation:

One way of doing this problem is to multiply the numerators 8 and 2 together and then divide the result by 5:

 8*2

-------- = 16/5

   5

In turn, 16/5 can be rewritten as 32/10, or 3 1/5

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

x= total number of sets bought

y= total cost

Since each set costs 3 dollars, we can represent that with the equation y=3x, and the teacher also had a 2 dollar coupon, so we can subtract 2 from the equation, giving us y=3x-2

So, by looking at the charts, plug in x (the input), and see if the y (output) is the same as the equation represents.

So, the answer is A. To test, plug in the x and see if it gives the right y.

For example, 3 sets bought (x), so it will be represented as,

y=3x-2

y=3(3)-2

y=7

So when 3 is x, y is 7. Which is what answer choice A shows.

Answer:

y = 2/3x - 7

Step-by-step explanation:

(3, -5) (-3, -9)

and y = -7 when x = 0  from graph

so c = -7

m = -9 - (-5)  / -3 - 3

= -4 / -6

= 2/3

line equation is y = mx + c

y = 2/3 x + (-7)

y = 2/3x - 7

[tex]\\ \sf\longmapsto m=\dfrac{-9+5}{-3-3}[/tex]

[tex]\\ \sf\longmapsto m=\dfrac{4}{6}[/tex]

[tex]\\ \sf\longmapsto m=2/3[/tex]

Now

Equation of line

[tex]\\ \sf\longmapsto y=mx+b[/tex]

[tex]\\ \sf\longmapsto y=\dfrac{2}{3}x-7[/tex]

Answer:

x = 5

Step-by-step explanation:

RS  +ST =  RT

2x + 10 + x - 4 = 21

2x + x + 10 - 4 = 21   {Combine like terms}

3x + 6 = 21

Subtract 6 from both sides

3x = 21 - 6

3x = 15

Divide both sides by 3

x = 15/3

x = 5

bearing in mind that a function never has X-repeats, or namely the 1st value of each coordinate is never repeated, let's check these ones, who has an X-repeat and doesn't, Check the picture below.

Using the normal distribution and the central limit theorem, it is found that there is a 0.6328 = 63.28% probability that a random sample of 100 accounting graduates will provide an average that is within $902 of the population mean.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

Hence, the probability of sample having mean within M of the population mean is the p-value of [tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex] subtracted by the p-value of [tex]Z = -\frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex].

In this problem, we suppose [tex]\sigma = 10000[/tex], and thus, with a sample of 100, we have that [tex]s = \frac{10000}{\sqrt{100}} = 1000[/tex].

[tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]Z = \frac{902}{1000}[/tex]

[tex]Z = 0.902[/tex]

[tex]Z = 0.902[/tex] has a p-value of 0.8164.

[tex]Z = \frac{M}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]Z = -\frac{902}{1000}[/tex]

[tex]Z = -0.902[/tex]

[tex]Z = -0.902[/tex] has a p-value of 0.1836.

0.8164 - 0.1836 = 0.6328.

0.6328 = 63.28% probability that a random sample of 100 accounting graduates will provide an average that is within $902 of the population mean.

B.    The axis of symmetry is x = 1.5 and the vertex is (1.5, 12.75).

Step-by-step explanation:

I will solve the problem by applying the perfect square trinomial. In this way we obtain the canonical form. Another way would be to derive the function, but I don't know if you're familiar with it.

First: let us take out the common factor: , since we remember that the canonical form is characterized as follows:

Then, it remains:

Then: the coefficient of the variable  We divided it between , And we square it (they will be one positive and one negative). In our case:

Let's accommodate terms to make it easier:

Can be written as :

Now, what is underlined is our perfect square trinomial, let us recall its form:

Applying the same principle we are left:

Applying distributive property we get:

Therefore it will have its vertex in:  

The axis of symmetry is a straight line that makes the function to be projected being , for this you need some reference point, for the parabola you need the coordinate in  of the vertex.

For which the axis of symmetry is .

Explanation:

Vertex form of a quadratic can be written as ...

  a(x -h)² +k = 0 . . . . . . vertex (h, k); scale factor 'a'

First of all, it highlights the vertex (x, y) = (h, k), which is the extreme maximum or minimum of the function. That also tells you the axis of symmetry, (x = h).

Vertex form also shows you the vertical scale factor. The sign of that tells you whether the graph opens upward (positive) or downward (negative). The numerical value of it tells you the vertical distance from the vertex to points ±1 unit either side of the vertex.

The roots of the quadratic will be ...

  x = h ±√(-k/a)

These will be complex if the graph does not intersect the x-axis.

Answer:

From the vertex form  ()=(−)+ , you can find the vertex  (,)  and see whether the parabola opens upward (if  > ) or downward (if  < ). From a graph, you can read the coordinates of the vertex and substitute into the vertex form. With the coordinates of one other point, you can solve the equation to find a and write the equation of the quadratic function in vertex form.
