Does this graph represent a function?
yuradex [85]

Answer:

Yes

Step-by-step explanation:

Graphs are functions when there is only one output for every input. In other words, for every "x" value, there must be only "y" value. This graph depicts a function because it abides by this rule. To be exact, this is an exponential function with the formula: f(x) = (x + 2)².

Shiny White dental insurance costs $258 per year. Approximately one-third of insured people need a filling, which averages $110
sveta [45]

Answer:

  about $145.33

Step-by-step explanation:

Consider a group of 15 customers. They will pay ...

  15 × $258 = $3870

in premiums each year.

One-third of those, 5 customers, will submit claims for fillings, so will cost the insurance company ...

  5 × $110 = $550

And 80% of them, 12 customers, will submit claims for preventive check-ups, so will cost the company ...

  12 × $95 = $1140

The net income from these 15 customers will be ...

  $3870 -550 -1140 = $2180

Then the average income per customer is this value divided by the 15 customers in the group:

  $2180/15 = $145.33

_____

<em>Alternate solution</em>

Above, we chose a number of customers that made 1/3 of them and 4/5 of them be whole numbers. You can also work with one premium and the probability of a claim:

  258 - (1/3)·110 - 0.80·95 = 145.33

Graph the solution to this system of inequalities in the coordinate plane.
Vsevolod [243]

By using Geogebra online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.

<h3>What is an inequality?</h3>

An inequality is a mathematical relation that compares two (2) or more integers and variables in an equation based on any of the following:

  • Less than (<).
  • Greater than (>).
  • Less than or equal to (≤).
  • Greater than or equal to (≥).

Given the following system of inequalities:

3y > 2x + 12  ⇒ 3y - 2x > 12

2x + y ≤ -5

By using Geogebra online graphing calculator, the solution to this system of inequalities are plotted in the image attached below.

Order the following numbers from least to greatest :
guapka [62]
You can choose to put all the numbers into decimals or fractions.
In this case, I will put the numbers all in decimals. 
We already have 2.07, -2.67, and 2.67 
2 \frac{7}{10} in a decimal is 2.7 because 7 is in the 'tenths' place and ten was our denominator
So all of our numbers are 2.7 2.01 2.67 and -2.67
Obviously a negative number will be last and you can line the other numbers to see which is the greatest
2.67
2.70 (if there is nothing there we can always put a zero)
2.01
So the first digit is all 2 so we look at the next digits which are 6, 7, and 0 
You should know how to order those numbers, so do the same here.
-2.67, 2.01, 2.67 2\frac{7}{10} (we had to change it back to a fraction) 
Hope that helped :)
