Note: It seems you may have unintentionally missed writing the complete question. As total cost is missing.

So, I am assuming how many tickets Mr. XYZ can buy if he/she pays 188 dollars.

The solution would still clear your concept though.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the function

$c(x)=18x-10$

The slope-intercept form of the line equation

We know that the slope-intercept form of the line equation

$y = mx+b$

where m is the slope and b is the y-intercept

comparing with the slope-intercept form of the line equation

here:

rate of change = 18

c(x) or y represents the cost

and

'x' represents the number of tickets

Assuming the total cost i.e. c(x) = $188

In order to determine the value of x, set c(x) = 188

i.e.

188 = 18x -10

switch sides

188x - 10 = 170

add 10 to both sides

18x - 10 + 10 = 188 + 10

18x = 198

Divide 18 to both sides

18x/18 = 198/18

x = 11

Therefore, if you can buy x = 11 tickets if you pay 170 dollars.

This is the well known Monty Hall problem.

Let A,B,C denote the events "The ferrari is behind A" and so on
Let HA,HB,HC denote the events "The host opens A" and so on

By Baye's formula, $P(B)_{HC}=\frac{P(HC)_BP(B)}{P(HC)}=\frac{\frac{1}2\cdot\frac{1}3}{\frac{1}2}=\frac{1}3$ whereas $P(A)_{HC}=\frac{P(HC)_AP(A)}{P(HC)}=\frac{1\cdot\frac{1}3}{\frac{1}2}=\boxed{\frac{2}3}$ !!

Find the sum of the measure of the exterior angle of the convex polygon

Yuri [45]

No matter what type of polygon you have, the sum of the exterior angles is ALWAYS equal to 360°. If you are working with a regular polygon, you can determine the size of EACH exterior angle by simply dividing the sum, 360, by the number of angles.
