Answer:

Alternative C is not true for a function.

Step-by-step explanation:

This is because a single x-value (domain) can not be mapped onto two unique y-values (range) since this violates the definition of a function defined by a relation

Answer:

C) Domain is {2}, Range is {2, 3}

Step-by-step explanation:

For one value of x there are two values of y, which contradicts the definition of a function.

Definition of a function:

A function is an equation for which any x that can be plugged into the equation will yield exactly one y out of the equation.

<em>All the other options follow this definition except C</em>

kiruha [24]

Answer:

(a)

$\begin{array}{ccc}{Industry} & {Frequency} & {\%Frequency} & {Bank} & {26} & {13\%} & {Cable} & {44} & {22\%} & {Car} & {42} & {21\%}& {Cell} & {60} & {30\%} & {Collection} & {28} & {14\%} & {Total} & {200} & {100\%} \ \end{array}$

(b): Cell industry

Step-by-step explanation:

Given (Missing from the question)

$Bank = 26$

$Cable = 44$

$Car = 42$

$Cell = 60$

$Collection = 28$

$Total = 200$

Solving (a) Show the frequency and percent frequency.

The percentage frequency is calculated by:

$\%Freq = \frac{Freq}{Total} * 100\%$

So. we have:

$\%Freq = \frac{26}{200} * 100\% = 13\%$ -- Bank

$\%Freq = \frac{44}{200} * 100\% = 22\%$ --- Cable

$\%Freq = \frac{42}{200} * 100\% = 21\%$ --- Car

$\%Freq = \frac{60}{200} * 100\% = 30\%$ --- Cell

$\%Freq = \frac{28}{200} * 100\% = 14\%$ --- Collection

The table becomes:

Solving (b): The industry with the highest complaints

From the above table, the highest frequency is 60 and this represents the number of complaints of Cell industry.

Hence, the cell industry has the highest number of complaints

Solving (c): Comment

The percentage frequency table shows that the industry with the highest number of complaints is the cell industry (at 30%) and the industry with the least is the banking industry (at 13%)

Llana [10]

Answer:

32 pages will have advertisements.

Step-by-step explanation:

As it has been given in the question that out of 383 pages out of 960 pages of "rise over the run" contained an advertisement.

We have to calculate the pages having advertisements using this information.

since 383 out of 960 pages have the advertisement which is 383×100/960=40%

Now if we have 80 pages in this week's edition then 40% of the total pages will have advertisement.

Number of pages with advertisements = 80×40% = 32 pages.

The actual length is 6*40=240 cm, 8*40=320 cm, 10*40=400 cm. And the angle measures of the actual sign will not change. The transformation can be turning over using the hypotenuse as axle. Or rotate the triangular sign 180° using the center of the triangle as the center of rotation. The turning over method will accomplish.

jasenka [17]

Answer:

$\$(10-p)$

Nicholas used a $10 bill to pay for a granola bar that only costs p dollars.

To find much change Nicholas received, simply subtract the cost of granola bar from the amount of money Nicholas paid:

$\$(10-p)$

For example, if granola bar costs p=$4, then Nicholas gets
