Tickets to a sporting event cost $125 each. What's a reasonable domain and range.

djverab [1.8K]

The domain and the range of a function is the set of input and output values of the function.

The domain is the set of all whole numbers.

The range is the set of all whole numbers.

Let the number of tickets be x, and the revenue be y.

So, the revenue function will be:

y = 125

The number of tickets cannot be less than 0.

So, the domain of the revenue function is

domain=0,∞

The above means that, the domain is the set of all whole numbers

Similarly, the revenue cannot be less than 0.

So, the range of the revenue function is

range = 0,∞

The above means that, the range is also the set of all whole numbers (in multiples of 125).

Question 8 options:

prisoha [69]

Answer:

Step-by-step explanation:

Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.

c first:

$\frac{c-8}{8-0}=34$ and

$\frac{c-8}{8}=34$ and

c - 8 = 272 s0

c = 280

For a:

$\frac{5-8}{a-0}=34$ and

$\frac{-3}{a}=34$ and

-34a = 3 so

$a=-\frac{3}{34}$

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.

A certain candle is designed to last nine hours. However, depending on the wind, air bubbles in the wax, the quality of the wax,

Ierofanga [76]

Answer:

Step-by-step explanation:

a) P(X > 6) = (9.5-6)/(9.5-5.5) = 3.5/4 = 0.875

b) P(X < 7) = (7-5.5)/(9.5-5.5) = 1.5/4 = 0.375

c) E(X) = (9.5+5.5)/2 = 7.5

Standard deviation = (9.5-5.5)/sqrt(12) =4/3.46 = 1.154

P= 1.156*2/(9.5-5.5) = 2.308/4 = 0.577

d) P(X > t) = 0.25

(9.5-t) /(9.5-5.5) = 0.3

9.5-t = 1.2

t = 9.5-1.2 = 8.3

A teacher has 36 sheets of construction paper and 78 markers. She wants to pack them in boxes with the same number of sheets and

ArbitrLikvidat [17]

Answer:

6 boxes.

Step-by-step explanation:

We have been given that a teacher has 36 sheets of construction paper and 78 markers.

As teacher wants to pack the same number of sheets and markers in each box, So we will have to find the greatest common factor (GCF) of 36 and 78.

Factors of 36 are: 1, 2, 3, 4, 6, 6, 18 ,12, 18, 36

Factors of 78 are: 1, 2, 3, 26, 39, 78.

We can see that GCF of 36 and 78 is 6. The number of sheets of construction paper in each box will be 6 (6*6=36) and number of markers in each box will be 13 (13*6=78).

Therefore, the greatest number of boxes the teacher can use to pack the sheets of construction paper and markers is 6.
