Hitman42 [59]

Answer: 2.127

Step-by-step explanation:

For this problem, we have to divide the number 212.7 by 100 cookies.

212.7 ÷ 100 = 2.127

So, each cookie will require 2.127 ounces of dough.

Which table shows a function whose range has exactly three elements

Rudik [331]

<h2>Answer:</h2>

The table which shows that a function's range has exactly three elements is:

x y

3 8

4 6

5 12

6 8

<h2>Step-by-step explanation:</h2>

<u>Domain of a function--</u>

The domain of a function is the set of all the x-values i.e. the value of the independent variable for which a function is defined.

<u>Range of a function--</u>

It is the set of all the y-value or the values which are obtained by the independent variable i.e. the values obtained by the function in it's defined domain.

x y

1 4

2 4

3 4

Domain: {1,2,3}

Range: {4}

Hence, the range has a single element.

x y

3 8

4 6

5 12

6 8

Domain: {3,4,5,6}

Range: {6,8,12}

Hence, the range has three element.

x y

0 5

2 9

0 15

This relation is not a function.

because 0 has two images.

0 is mapped to 5 and 0 is mapped to 15.

x y

1 4

3 2

5 1

3 4

This relation is not a function.

because 3 has two images.

3 is mapped to 2 in the ordered pair (3,2) and 3 is mapped to 4 in the ordered pair (3,4)

The Fall Festival charges $0.75 per ticket for the rides. Kendall bought 18 tickets for rides and spent a total of $33.50 at the

PIT_PIT [208]

The variable y is the dependent variable and the variable x is the independent variable.

The cost of one ticket is $0.75. Therefore, the cost of 18 tickets will be:

$0.75\times 18=13.5$ dollars

Now, we know that Kendall spent her money only on ride tickets and fair admission and that she spent a total of $33.50.

Therefore, the price of the fair admission is: $33.50-$13.50=$20

If we use y to represent the total cost and x to represent the number of ride tickets, the linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission can be written as:

$y=0.75x+20$ ......Equation 1

<u>Part (c)</u>

The above equation is logical because, in general, the total cost of the rides will depend upon the number of ride tickets bought and that will be 0.75x. Now, even if one does not take any rides, that is when x=0, they still will have to pay for the fair admission, and thus their total cost, y=$20.

Likewise, any "additional" cost will depend upon the number of ride tickets bought as already suggested. Thus, the total cost will be the sum of the total ride ticket cost and the fixed fair admission cost. Thus, the above Equation 1 is the correct representative linear equation of the question given.
