Answer:

Step-by-step explanation:

A function of x means that there can only be one value of y per x value. Therefore, D does not match this because there are 4 values of y per x value (3).

Answer:

Step-by-step explanation:

Each x value can have only ONE y value

this means that there cannot be more than one of the same x value:

think of the x values as an input, each input has one output right?

ex:

input: 7

output:8

input:3

output:2

how is it possible that the same input has different outputs?

input: 5

output: 6,7

this does not make any sense, one input should only have one output hence, one value of x(input) should have only one value of y(output)

Hope this helps!

Answer:

B. The interquartile range (IQR) for town A, 20, is greater than the

IQR for town B, 10.

Step-by-step explanation:

IQR = Q₃ - Q₁

For the town A:

Q₃ = 40 and Q₁ = 20

IQR of town A = 40 - 20 = 20

For the town B:

Q₃ = 30 and Q₁ = 20

IQR of town A = 30 - 20 = 10

Check the given options:

The most statement is appropriate comparison of the spreads is B

The tax rate as a percent, r, charged on an item can be determined using the formula – 1 = r, where c is the final cost of the i

melisa1 [442]

The correct answer is:

$43.20

Explanation:

The formula we have is

c = p(1+r), where c is the total cost, p is the price of the item before tax, and r is the tax rate written as a decimal. This formula comes from the fact that adding a percent tax to the cost of an item takes 100% of the price and adds r% to it; this is why we multiply the price by (1+r).

Since our tax rate is 8%, r = 8% = 8/100 = 0.08. The price of the item is $40. Using this information, we have:

c = 40(1.08) = $43.20

Part A: This data does represent a function because no value of x is repeated.
Part B: If x = 6 for the relation f(x) = 7x - 15, then f(x) will equal 27. The function f(x) = 7x - 15 will have the greater value
Part C: If f(x) is equal to 6 then x will equal 3
