C:Neither funtion nor relation

C:Ni función ni relación

espero que te sirva marcarme como mejor respuesta PORFA y gracias

Answer:

relation only

Step-by-step explanation:

A relation is a set of one or more ordered pairs.

A function is a relation in which each element of the domain is paired with EXACTLY one element of the range.

The Vertical-Line Test: Given the graph of a relation, if a vertical line can be drawn that does not cross the graph in more than one place, it is a function.

Any vertical line drawn where x > -4 will cross the graph in more than one place.

Therefore, the graph is not a function, it is a relation only.

Answer: -3.7

Step-by-step explanation:

Step 4 is wrong 6.1 - 9.8 = -3.7

Answer:

The answer is 9.

Step-by-step explanation:

I had the question on one of my quizzes.

Answer: 4. No, the graph is NOT a function because using the vertical line test, it intersects at two points at a time.

5. Yes, it is a relation, and it is also a function because once those points are plotted if given the vertical line test, there would not be two points crossed at once. So, yes, it is a function.

6. Yes, it is a relation. No, it does NOT make up a function because a vertical line would intersect all the points given.

Answer:

Im too gucci. 88.

Step-by-step explanation:

A affects the slope of the graph.

When a is less than 1, the amplitude of the graph decreases which causes the slope of the graph to appear more flat.

When a is greater than 1, the amplitude of the graph increases which causes the slope of the graph to appear more steep.

Answer:

★ Divisibility rule for 3 -

If the sum of all the digits divisible by 3 then the number is divisible by 3.

Here, we take an example for better understanding -

Example 1 - 3525

Add up the digits - 3 + 5 + 2 + 5

→ 15

As, 15 is divisible by 3. So, 3525 is a factor of 3.

★ Divisibility rule for 6 -

A number is to be divisible by 6 , if the number is also divisible by 2 and 3.

Example 2 - 132

Add up the digits = 1 + 3 + 2 = 6

As, 6 is divisible by 2 and it's also divisible by 3. Then, 132 is a factor of 6.

★ Divisibility rule for 9 -

If the sum of all the digits is divisible by 9 then the number is divisible by 9. Just like we'd in 3.

Example 3 - 1052

Add up the digits - 10 + 5 + 2 = 17

As, 17 is not divisible by 9. So, 1052 is also not divisible by 9.

Answer:

y = |-x-1| + 8.

Step-by-step explanation:

A reflection across the y axis gives the equation y = |-x -1| + 7.

Then a translation up 1 unit gives the equation y = |-x-1| + 8.

Step-by-step explanation: He will get the answer correct because if you add the 6 & 1 together it equals Seven. Seven was the original number that was supposed to be subtracted from 16.

Answer:

11 out of 39

Step-by-step explanation:

Answer:

\frac{11}{39}

39

11

Step-by-step explanation:

There are 39 fruits in all.

11 + 6 + 9 + 13= 3911+6+9+13=39

Therefore, there would be 39 total events.

There are 11 preferred events, as there are eleven oranges out of the 39 fruits.

\frac{preferred}{total} =\frac{11}{39}

total

preferred

=

39

11

So, there should be a 11/39 chance that a person would pick an orange.

\frac{11}{39}

39

Answer:

10 teaspoons

Step-by-step explanation:

1 dozen of cookies= 12 cookies

4 teaspoon of cinnamon ----- 2(12)= 24 cookies

Amount of cinnamon needed per cookie

[tex] = \frac{4}{24} \\ = \frac{1}{6} \: teaspoon[/tex]

Teaspoons of cinnamon needed for 60 cookies

[tex] = 60( \frac{1}{6} ) \\ = 10[/tex]

Thus, 10 teaspoons of cinammon is needed for 60 oatmeal cookies.

Answer:

The lcm (least common multiple) of 4 and 12 is 12.

Step-by-step explanation:

Find the prime factorization of 4

4 = 2 × 2

Find the prime factorization of 12

12 = 2 × 2 × 3

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 3

LCM = 12

The Least common multiple of 4 and 12 is 12.

I hope this helps!

Answer:

what do you need to to know 1) what kind of function its or 2) whats the answer of y and/or x

Answer:

(y, -x -6)

Step-by-step explanation:

The coordinates of PQRS is not given, however we'll assume the coordinates of PQRS to be (x,y)

The first transformation: 6 units right

[tex](x,y) -> (x + b, y)[/tex]

Where b = 6

So, the new coordinates will be

[tex](x + 6, y)[/tex]

The second transformation: 90° clockwise

[tex](x,y) -> (y,-x)[/tex]

So, the new coordinates will be

[tex](x + 6, y)-> (y, -x -6)[/tex]

Hence, the new coordinates of PQRS is (y, -x - 6)

Answer:

The 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).

Step-by-step explanation:

The (1 - α)% confidence interval for the difference between population means is:

[tex]CI=(\bar x_{1}-\bar x_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\sigma^{2}_{1}}{n_{1}}+\frac{\sigma^{2}_{2}}{n_{2}}}[/tex]

The information provided is as follows:

[tex]n_{1}= 138\\n_{2}=156\\\bar x_{1}=61\\\bar x_{2}=64.6\\\sigma_{1}=18.53\\\sigma_{2}=13.43[/tex]

The critical value of z for 98% confidence level is,

[tex]z_{\alpha/2}=z_{0.02/2}=2.326[/tex]

Compute the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 as follows:

[tex]CI=(\bar x_{1}-\bar x_{2})\pm z_{\alpha/2}\times \sqrt{\frac{\sigma^{2}_{1}}{n_{1}}+\frac{\sigma^{2}_{2}}{n_{2}}}[/tex]

     [tex]=(61-64.6)\pm 2.326\times\sqrt{\frac{(18.53)^{2}}{138}+\frac{(13.43)^{2}}{156}}\\\\=-3.6\pm 4.4404\\\\=(-8.0404, 0.8404)\\\\\approx (-8.04, 0.84)[/tex]

Thus, the 98% confidence interval for the true difference between testing averages for students using Method 1 and students using Method 2 is (-8.04, 0.84).
