Which region represents the solution to the given system of inequalities?
Phoenix [80]

Answer: The intersection region shown in the graph attached is the solution of the system of inequalities.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

 Given the following system of inequalities:

\left \{ {{x+3y\leq-3 } \atop {x\geq3 }} \right.

We need to graph the lines.

We have the line:

x+3y=-3

Solving for "y", we get:

3y=-x-3\\\\y=\frac{1}{3}x-1

Knowing that m=-\frac{1}{3} and b=-1, we can graph it.

Since the symbol is \leq, the line must be solid.

The other line is:

x=3

Since "x" only takes one value, we can identify that it is a vertical line, so we can graph it.

Since the symbol is \geq, the line must be solid.

We need to substitute a point that is not on the line, into each inequalities. Let's choose the point (0,0).

Then:

0+3(0)\leq-3\\\\0\leq-3

This is false, therefore, we must shade the half that does not contain this point.

0\geq 3

This is false, so we must shade the half that does not contain this point.

The intersection region of the solutions (Observe the graph attached) of the given inequalities is the solution of the system of inequalities.

Suppose a plane has 500 seats. From experience, it's known that 10% of people who have bought the ticket do not show up. Now, 55
oksano4ka [1.4K]

Answer:

The probability that there will be enough seats for all people who turn up is 0.78

Step-by-step explanation:

Given:

A = 500

B = 550

Since it is known from experience that 10% of people who bought tickets don't show up, to find the probability that there will be enough seats for those who show up, we have:

Percentage that will turn up = 100℅ - 10℅ = 90℅

Since 90℅ will turn up, that means the number of passengers will be less than 500.

Therefore for P less than or equal to 500, we use:

P ( X <_ 500) =

= [500 + 0.5 - (550 * 0.9)] / sqrt*(550 * 0. 9 * 0.1)

= 0.78

Therefore, the probability that there will be enough seats for all people who turn up is 0.78
