HowmanyCaliforniaresidentsdoyouexpecttoneedtosurveyuntilyoufindaCaliforniaresidentwhodoesnot have adequate earthquake supplies? g. How many California residents do you expect to need to survey until you find a California resident who does have adequate earthquake supplies?
Answer:
Step-by-step explanation:
We are given that 30% of California residents have adequate earthquake supplies.
a) Ramon variable X denotes the number of the california residents that have adequate earthquake insurance
B) x can take value 1 ,2 ,3 ......
C)The distribution of random variable is geometric distribution with parameter p=0.3
The pmf of geometric distribution is
[tex]P(X=x)=0.3(1-0.3)^{x-1} , x=1,2,3...[/tex]
D)P(X=1) or P(X=2)=P(X=1)+P(X=2)
P(X=1) or P(X=2)=[tex]0.3(1-0.3)^{1-1}+0.3(1-0.3)^{2-1}=0.51[/tex]
E)
[tex]P(X \geq 3)=1-P(X<3)\\P(X \geq 3)=1-(P(X=1)+P(X=2))\\P(X \geq 3)=1-0.51\\P(X \geq 3)=0.49[/tex]
F)
[tex]E(X)=\frac{1}{p}[/tex]
p is the resident who does not have adequate earthquake supplies.
p = 1-0.3 = 0.7
[tex]E(X)=\frac{1}{0.7}=1.42[/tex]
G)[tex]E(X)=\frac{1}{q}=\frac{1}{0.3}=3.33[/tex]

Answer:
x=1/8
Step-by-step explanation:
First we need to isolate the variable. We can do that by subtracting 3 from each side. You then get: 24x-2=1. Then, to completely isolate it, add 2 to each side. We get 24x=3. Now divide 24 from each side to get only x. We get 3/24, which can be rewritten as 1/8.
What is the equation of the line that passes through the point (-5, 2) and has a
slope of 4/5 ?
Answer:
y - 2 = 4/5(x + 5)
Step-by-step explanation:
Well, the equation format your question is asking for is Point-slope form which is represented by:
[tex]y - y^{1} = m (x - x^{1})[/tex]
[tex]y^{1}[/tex] = y in point
[tex]x^{1}[/tex] = x in point
m = slope
Now, we have to input our values into our equation.
y - 2 = 4/5(x + 5)
Hope this Helps! :)

Which relationship is an inverse variation?
x 2 4 6 8
f(x) 12 6 4 3
x 1 2 3 4
f(x) –1 –2 –3 –4
x 1 2 3 4
f(x) 4 16 36 64
x 2 4 6 8
f(x) 6 12 18 24
The relation that is an inverse variation is the one in the first table:
x 2 4 6 8
f(x) 12 6 4 3
Which relation is an inverse variation?An inverse variation between two variables x and y can be written as follows:
y = k/x
Where k is a constant.
Notice that x is on the denominator, so, as x increases, the value of y decreases.
Now, for example if we use the values of the first table:
x 2 4 6 8
f(x) 12 6 4 3
The first pair is (2, 12)
Replacing that in the inverse variation formula we get:
12 = k/2
12*2 = k
24 = k
For the second pair (4, 6) we will get:
6 = k/4
6*4 = k
24 = k
And so on for all the pairs. If the variation is inverse, you should always get the same value of k (like in this case).
So this is the correct answer.

You reverse the inequality symbol when you multiply or divide both sides of an inequality by the same negative number.
True or false?
Step-by-step explanation:
The statement is true, because when we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.
What is Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
Let an example of the inequality as;
⇒ 2x < 3
Multiply by - 1, we get;
⇒ - 2x > - 3
Thus, When we multiply or divide both sides of an inequality by the same negative number we reverse the inequality symbol.

A regular hexagon is inscribed in a circle with radius 9 cm. Find the area
Answer:
121.5sqrt(3)
Step-by-step explanation:
Ok, so all regular hexagons are made out of 6 equilateral triangles. If the hexagon is inscribed in the circle, the radius lines up with a side of one of the 6 equilateral triangles and you get 6 equilateral triangles with a side length of 9.
The formula for an equilateral triangle's area is (a/2)^2 * sqrt(3) where a = side length. That means we just plug in 9 to find the area of one of these six triangles. We get 20.25sqrt(3).
We multiply this by 6 (to find the sum of the areas of 6 equilateral triangles) and get 121.5sqrt(3)
The area of the hexagon will be 210.4 cm².
What is a hexagon?The definition of a hexagon in mathematics and geometry is a polygon with six straight sides that is closed in two dimensions.
Given, a circle with a radius of 9 cm. which have a regular hexagon whose all corner touch the circle. If we draw a radius of a circle at the corner of the hexagon. then we get six equilateral triangles.
A regular hexagon is 6 equilateral triangles of side r and area
Area of triangle = (r/2)(√3r/2)
so the total area is
A(hex ) = (6/4) √3r² = 3√3(r²)/2
r = 9m so
A = 210.4m²
Hence the Area of the given hexagon is 210.4 square meters.

if she goes to gitnasium 1 more time then it eould be more than Fit-Quest.
16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have been given that Fit-quest charges a one-time registration fee of $50 plus $5 per fitness class. Fitnasium charges no registration fee, but charges $8 per fitness class.
Let the number of classes would be x
⇒ 50 + (5x) = 8x
Rearrange the terms of x in the above equation,
⇒ 8x - 5x = 50
⇒ 3x = 50
⇒ x = 50/3
Apply the division operation,
⇒ x = 16
Therefore, 16 of the fitness classes do Fitnasium cost less than or the same as Fit-quest.
