Answers
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]

Answers
Answer: slope = 21, y-int = 15
Step-by-step explanation:
f(x) = -7x + 9
g(x) = -7(x + 2) + 9 = -7x - 5
h(x) = -3(-7x - 5) = 21x + 15

Slope is 1/2
The slope of the line through (6, -7) and (4, -8)
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
where (x₁, y₁) and (x₂, y₂) are the two points that you are trying to find the slope between.
Given;
Two points; (6, -7) and (4, -8)
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m=(-8-(-7))/(4-6)
m=(-1)/-2
m=1/2

We are trying to find out the width if the SA is 240 square inches, length is 12 inches, and the height is 5 inches. Let's plug these numbers into the equation.
240=(2*12*w)+(2*12*5)+(2*5*w)
24w+120+10w
240= 34w+120
-120 -120
120= 34w
120/34 = 34w/34
w is approximately equal to 3.5 which can be rounded to 4

y=. x. +
Answers
Answer:
y = 6x + 27
Step-by-step explanation:
The required linear equation would be y = 6x + 27 in the slope-intercept form.
What is a Linear Function?A linear function is defined as a function in the form of f(x) = mx + c where 'm' and 'c' are real numbers.
It represents the line's slope-intercept form, which is written as y = mx+ c.
Linear equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing.
The linear equation is given in the question
⇒ 2x = (1/3)y - 9
We have to rewrite the equation in the slope-intercept form.
⇒ 2x = (1/3)y - 9
Multiply by 3 both sides of the above equation,
⇒ 6x = y - 27
Rearrange the term of y to get
⇒ y = 6x + 27
Therefore, the required linear equation would be y = 6x + 27 in the slope-intercept form.

1 Two functions are shown below. Function A Function B x 0 3 5 y 5 3x 1 2 y 3 9 13 Which statement correctly describes the rates of change of the two functions? A The rate of change is 2 for both Function A and Function B. B The rate of change is 3 for both Function A and Function B. C The rate of change is greater for Function A than for Function B. D The rate of change is greater for Function B than for Function A.
Answers
Answer:
D The rate of change is greater for Function B than for Function A
Step-by-step explanation:
A function shows the relationship between a dependent variable and an independent variable. A linear function is given as y = mx + b, where m is the rate of change, y is the dependent variable, x is the independent variable and b is the value of y when x = 0.
Function B is given by y = 3x + 2. Comparing with y =mx + b gives m = 3. Therefore the rate of change of function B is 3.
Function A has x: 0, 3, 9 and y:3, 9, 13. Using the points (0,3) and (3, 9), we an get the equation of the function. The formula is:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{9-3}{3-0}(x-0)\\ \\y-3=2x\\\\y=2x+3[/tex]
Function A is given by y = 2x + 3. Comparing with y =mx + b gives m = 2. Therefore the rate of change of function A is 2.
The rate of change is greater for Function B than for Function A

(-6, -2), m = -2
y+2 = 2(x + 6)
y + 2 = -2(x + 6)
y + 2 = -2(x-6)
y - 2 = -2(x + 6)
Answers
y+2=-2(x+6)
Explanation:
Point-slope form: y-b=m(x-a) when the points are (x,y) and (a,b)
“M” means the slope.
Because we are already given a point, we just need to plug in the values as a and b. We can also plug in the value for the slope as m.
y-b=m(x-a)
y-(-2)=-2(x-(-6))
Two negatives make a positive
y+2=-2(x+6)

Brayden just lit a new candle and then let it burn all the way down to nothing. The
candle burned at a rate of 0.75 inches per hour and its initial length was 6 inches.
Write an equation for L, in terms of t, representing the length of the candle
remaining unburned, in inches, t hours after the candle was lit.
Answers
Answer:
L = -0.75t + 6
Step-by-step explanation:
L = length (this is what equation you are looking to solve for
-0.75t because the candle burns at 0.75 in per hour so the value decreases, hence the (-)
+6 because the candle has a positive value of 6 inches to begin with
The standard form of what you are writing is called slope intercept form y = mx + b, learn it because it is very important for future math.
The equation of the candle remaining unburned at any given time is L(t) = 6 - 0.75t.
What is a function ?A function is a set of values of the dependent variable for specified independent variable.
According to the given question Brayden just lit a new candle and then let it burn all the way down to nothing.
The candle burned at a rate of 0.75 inches per hour and its initial length was 6 inches we have to write an equation for L in terms of t where t represents time in hours and L(t) represents length of the candle remain unburned.
∴ L(t) = 6 - 0.75t.
At t = 0 the length of the unburned candle L(t) will be 6 inches and at t = 8 L(t) will be 0,So the candle can burn for 8 hours.
