<h2>
The required probability is 0.1224.</h2>
Step-by-step explanation:
Here, given:
The probability of having 0 dental checkup = 0.3
The probability of having 1 dental checkup = 0.6
The probability of having 2 dental checkup = 0.1
Number of people chosen at random = 7
So, the number of ways 2, 4 and 1 checkup are : 
Now, the combined probability that two will have no checkups, four will have one checkup, and one will have two checkups in the next year
= 
Hence, the required probability is 0.1224.
When it is said that a variable is inversely proportional to another, it is best to write out an equation to represent it.
This means;
y=k/x (where k is a constant number like 1 or 2, etc)
If you double x, the value of y is halved. I have attached a graph that shows this.
Hope I helped :)
Answer: 94 child tickets
<u>Step-by-step explanation:</u>
Let x represent child tickets
Let y represent adult tickets
Cost Equation: 5.70x + 9.75y = 1306.10
Quantity Equation: x + y = 173
Solve the system of equations using the elimination method:
Multiply the Quantity Equation by -5.70
5.70x + 9.75y = 1306.10
<u> -5.70x - 5.70y</u> = <u>-986.10</u>
4.05y = 320.00
<u> ÷4.05 </u> <u>÷4.05 </u>
y = 79
x + y = 173
x + 79 = 173
x = 94
If your trying to find the unit rate or the scale of the map, you need to figure out how many kilometers are per centimeters. To get that you need to do 63 divided by 9, witch would get you 7. So to my ability, the answer would be 1 cm per 7 kilometers. Hopefully this answer helped you and I'm hoping its correct.
r = 7.53 so d = 2r = 2(7.53) = 15.06 cm
Area of square = d^2 / 2 = (15.06)^2 / 2 = 113.41 cm^2
Area of circle = 3.14 (7.53)^2 = 178.04 cm^2
Area of yellow region = Area of circle - Area of square
Area of yellow region = 178.04 cm^2 - 113.41 cm^2
Area of yellow region =64.63 cm^2 = 64.6 cm^2 (nearest tenth)
Answer
64.6 cm^2
