Problem 11

Answer: Not a function

Why not? Because it fails the vertical line test. It is possible to draw a single straight vertical line through more than one point on this blue curve.

Put another way: An input like x = 2 produces more than one output (y = 2 and y = 4 at the same time). If we wanted a function, we need any given input in the domain to produce exactly one and only one output.

=============================================================

Problem 15

Answers:

Explanation:

The domain is the set of allowed x values. The left-most point on the blue curve is when x = -4, which is the smallest item allowed in the domain. The largest value allowed is x = 2, as this occurs at the right-most point on the blue curve. Therefore, our domain here is [tex]-4 \le x \le 2[/tex]

The range is similar, but we focus on y values this time. The lowest the graph goes is y = 2, and the highest it goes is y = 6. So [tex]2 \le y \le 6[/tex] represents the range of possible y outputs.

For both the domain and range, both endpoints are included.

=============================================================

Problem 16

Answers:

Explanation:

We follow the same idea as before. This time however, we have open holes which means that we do not include the endpoints.

The domain is [tex]2 < x < 7[/tex] since the curve spans from x = 2 to x = 7, excluding both of those x values. The range is [tex]1 < y < 6[/tex] for similar reasoning.

Notice how both problems 15 and 16 are functions because they pass the vertical line test. It is not possible to draw a single vertical line through more than one point on either blue curve.

Answer:

  (a) 3%

  (b) sh 3915

Step-by-step explanation:

a) The extra amount is ...

   10815 -10500 = 315

As a percentage of the marked price, this is ...

  315/10500 × 100% = 3%

__

b) The total paid is the sum of the down payment and the monthly installments:

  10815 = down + 1150×6

Answer:

Step-by-step explanation:

Because "How Tall are the students in my class?" and "How much do the students oon the team weigh,?" can vary. If you ask a question about one person, it is not a statistical question because the answer cant vary.

An answer will vary with 2 or more things.

Hope I helped.

How many hours per week do you practice sports? does not represent a statistical question because it asks for a fixed quantity, i.e., the number of hours per week someone practices sports, which does not involve variability or differences among data.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

A statistical question is a question that can be answered through data analysis and involves variability or differences among data.

It usually requires collecting data from a sample or population, organizing and summarizing the data, and drawing conclusions from the results.

How tall are the students in my class and How much do the students on the football team weigh represent statistical questions because they involve collecting data on a characteristic or variable of a population, such as height or weight.
These questions can be answered through data analysis and provide information on the variability or distribution of the characteristic in the population.

Hence, Option B does not represent a statistical question because it asks for a fixed quantity, i.e., the number of hours per week someone practices sports, which does not involve variability or differences among data.

Answer:

the interior angles is (n - 2) * 180.

Step-by-step explanation:

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.

I Hope This Helps!!!!

Answer:

180

Step-by-step explanation:

Answer:

∠5 = 80

Step-by-step explanation:

∠4 =  ∠2         {Corresponding angles are equal}

∠4 = 100

∠5 + ∠4 = 180 {linear pair}

∠5 + 100 = 180

          ∠5 = 180 - 100

         ∠5 = 80

Step-by-step explanation:

to find the answer, you want to convert the fractions into decimals.

to do that, you need to divide 1 by the denominato then multiply by the numerator.

ex: 3/4

1÷4=0.25

0.25×3= 0.75

That will give you an idea where to put it in the number line.

Answer:

Step-by-step explanation:

ZTU = 75, since RTS and ZTU are vertical angles, and RTS = 75.

TZU = 43, since TZU and QZX are vertical angles, and QZX = 43.

ZUT = 180 - ZTU - TZU = 180 - 75 - 43 = 62, since triangle ZUT is shown in the diagram, and the sum of its interior angles = 180.

YUW = 180 - 79 - 62 = 39, since TUW is a straight angle, which measures 180 degrees, and angle TUW is the sum of angle ZUY and angle ZUT and angle YUW, by the diagram.

YVU = 180 - ZUY - YUW = 180 - 68 - 39 = 73, since triangle YUV is shown in the diagram, and the sum of its interior angles = 180.

YVW = 180 - YVU = 180 - 73 = 107, since YVW and YVU are supplementary.

D. Water Temperature

Step-by-step explanation:

A scientist wants to test the effect of water temperature on the success of developing frog embryos. The scientist monitors developing  embryos in different water temperatures and counts the number of embryos that mature into tadpoles.

The water temperature is the independent variable because that is what the scientist is testing / changing.

Hopefully this helps!

Brainliest please?

Using variable concepts, it is found that the independent variable is given by:

D. Water temperature​

A function has the following format: y = f(x).

In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.

That is, the input of the function is the independent variable and the output is the dependent variable.

In this problem, the input is the water temperature, hence option D is correct.

Answer:

Step-by-step explanation:

1. Successive y-values have neither a common difference nor a common ratio. The table is neither linear nor exponential.

__

2. Successive y-values differ by 4. The table is linear.

__

3. Successive y-values have a ratio of 3. The table is exponential.

_____

Additional comment

For evenly-spaced x-values, the y-values will have a common difference for a linear function, and a common ratio for an exponential function.

If the table can be represented by a polynomial function, the level at which differences are constant will tell the degree of the polynomial. First differences are constant for a degree 1 (linear) function. Second differences are constant for a degree 2 (quadratic) function. This is the case in Table 1, where second differences are 2.
