C seems to make the most sense, logarithmic and exponential functions are not gradual, and a step function just wouldn't fit in my eyes.

Which table does NOT represent a linear function

topjm [15]

TABLE D does NOT represent a linear function

<h2>Explanation:</h2>

The Table is shown below. Each table is a relationship between two variables, namely x and y. By plotting each table in a graphing tool we get:

TABLE A, FIRST FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{8-5}{-1-0} \\ \\ m=-3$

TABLE C, SECOND FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{5-10}{-1-0} \\ \\ m=5$

TABLE C, THIRD FIGURE:

It is a linear function because we can draw a line that passes through all the points. By using two points, this line has a slope:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ m=\frac{1-2}{-1-0} \\ \\ m=2$

TABLE D, FOURTH FIGURE:

It is not a linear function. It is likely this is a parabola that opens downward.

The results of a survey are shown in the pie chart below and the survey 28 students say their favorite dessert is ice cream how

Rainbow [258]

Answer:

12 students.

Step-by-step explanation:

The complete question would be:

If ice cream is the last dessert, then we can solve for how many percent of the students like ice cream. If we add the 4 desserts percent, it should be equal to 100%

Pie : 15%

Candy : 23%

Cake : 27%

Pie% + Candy% + cake% + ice cream% = 100%

15% + 23% + 27% + Ice cream% = 100%

65% + Ice cream% = 100%

Ice cream% = 100% - 65%

Ice cream % = 35%

Percent is a way of saying how many out of a 100. Before we can tell how many students like pie, we need to figure out how many students were surveyed.

It says here that 35% of them like ice cream and among the students, 28 students like ice cream. This means that 28 is 35% of a number, which will be the number of students surveyed.

So as a fraction:

$35\% = \dfrac{35}{100}$

We need to find a ratio that is proportional to that, with 28 as the part of the whole.

$\dfrac{35}{100} = \dfrac{28}{x}\\\\Cross-multiply\\\\35x = 28(100)\\\\35x = 2800\\\\Divide\;both\;sides\;by\;35\\\\\dfrac{35x}{35} = \dfrac{2800}{35}\\\\x=80$

So that is the number of students survey. Now to look for how may people like pie, we find what is 15% of 80. So we find the part of the whole this time:

$\dfrac{15}{100}=\dfrac{x}{80}\\\\15(80)=100x\\\\1200 = 100x\\\\\dfrac{1200}{100}=\dfrac{100x}{100}\\\\12 = x$
