In Akutan, Alaska, men are 77% of the population. It is also known 11.3% of
Akutan males smoke cigars while 2.1% of Akutan females smoke cigars. One
member of the population is selected at random for a survey involving cell
phone carriers
Express the cigar smoking data as conditional probabilities.
Find the
probability that the selected subject does not smoke cigars given that the
subject is male
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Proportion of males, P(M) = 77% = 0.77
Proportion of females = ( 1 - proportion of males) = (1 - 0.77) = 0.23
Percentage of males who smoke cigar = 11.3% = 0.113
Percentage of female who smoke cigar = 2.1% = 0.021
Expressing cigar smoking Data as conditional probability :
P(male and smoking) = P(M n C) = 0.113
P(Female and smoking) = P(F n C) = 0.021
Probability of smoking cigar Given the person is a male :
P(C | M) = P(M n C) / P(M)
Probability of smoking cigar Given person is a female :
P(C | F) = P(F n C) / P(F)
Find the probability that the selected subject does not smoke cigars given that the subject is male?
No smoking Given Male = 1 - P(C | M)
P(C | M) = P(M n C) / P(M)
P(C | M) = 0.113 / 0.77
P(C | M) = 0.1467
1 - P(C | M)
1 - 0.1467
= 0.8533
-2.5(-2-3x)+2.5(-4x-1)=-2x-4x
Answer:
x=−0.714286
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2.5(−2−3x)+2.5(−4x−1)=−2x−4x
(−2.5)(−2)+(−2.5)(−3x)+(2.5)(−4x)+(2.5)(−1)=−2x+−4x(Distribute)
(7.5x+−10x)+(5+−2.5)=(−2x+−4x)(Combine Like Terms)
Step 2: Add 6x to both sides.
Step 3: Subtract 2.5 from both sides.
Step 4: Divide both sides by 3.5.

What is the scale factor of AABC to ADEF?
A. 6
B. 1/6
C. 2
D. 1/2
Answer:
1/6
Step-by-step explanation:
Side AB * scale factor = Side DE
72* scale factor = 12
Divide each side by 72
scale factor = 12/72
scale factor = 1/6
Option B is correct, 1/6 is the scale factor of triangle ABC to triangle DEF
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Dilation is a transformation, which is used to resize the object
The size by which the shape is enlarged or reduced is called as its scale factor.
DEF is dilated graph of ABC
Let us take any side of ABC and its corresponding side to find the scale factor
Side AB × scale factor = Side DE
72×scale factor = 12
Divide each side by 72
scale factor = 12/72
scale factor = 1/6
Hence, 1/6 is the scale factor of triangle ABC to triangle DEF

what is the equation of the line passing through the points (3,6) and (2,10)
Answer: y= - 4x+18
Step-by-step explanation:
Equation: y=mx+b
***remember: b is the y-intercept and m is the slope.
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
3= x1
2= x2
6= y1
10=y2
m=[tex]\frac{10-6}{2-3}[/tex]= [tex]\frac{4}{1}[/tex]= -4
m=-4
Now we have y=-4x+b , so let's find b.
You can use either (x,y) such as (3,6) or (2,10) point you want..the answer will be the same:
(3,6). y=mx+b or 6=-4 × 3+b, or solving for b: b=6-(-4)(3). b=18.
(2,10). y=mx+b or 10=-4 × 2+b, or solving for b: b=10-(-4)(2). b=18.

If you are given a graph, an equation, and a table; each representing a different linear function how would you determine which one has the greatest rate of change
Answer:
you would simply calculate the slope for each, a graph it is easy because you simply get two points on the graph and solve for it (y2-y1/x2-x1), an equation if it is in slope intercept form, the coefficient of x is the slope, from a table you use a similar method to a graph except you grab two values/instances, let's say in a table the numbers are presented like this:
3 4
2 6
You would then simply do the same thing for solving for the slope (y2-y1/x2-x1). In this instance it would be 6-2/4-3=4/1
All of these would give you the rate of change as the slope is the rate of change.

Ava turtle is half as old as her parrot in 10 years her turtle will be 3/4 as old as her parrot .write the equation to represent this situation.How old is avas turtle
Answer:
13
Step-by-step explanation:
I think the turtle would be 13 and 1/3 because we know that the turtle is half as old as the parrot. So if we divide 10 by 3/4 we can get how old the turtle is now
The system of the equation is :
[tex]2x=y\\3y-4x=10[/tex]
Thus, the age of the ava's turtle is 5 years.
Given:
Ava's turtle is half as old as her parrot.
The turtle will be 3/4 as old as her parrot in 10 years.
Let us assume the age of the turtle is x years and the age of the parrot is y years.
According to the first statement, the variables can be related as:
[tex]{x}=\dfrac{y}{2}\\2x=y[/tex]
According to the second statement, the variables can be related as:
[tex]\begin{aligned}x+10&=\dfrac{3}{4}(y+10)\\4(x+10)&=3(y+10)\\4x+40&=3y+30\\4x-3y&=-10\\3y-4x&=10\end{aligned}[/tex]
Thus, the system of the equation is :
[tex]2x=y\\3y-4x=10[/tex]
By solving the above system of the equation, we get x=5 and y=10.
Thus, the age of the ava's turtle is 5 years.
