Photos and videos have become an important part of the online social experience, with more than half of Internet users posting photos or videos online that they have taken themselves. Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves. A research center finds that P(A) = 0.47, P(B) = 0.28,and P(A or B) = 0.52.
Required:
What is the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves?
Answer:
0.82
Step-by-step explanation:
Given:
A be the event that an Internet user posts photos taken by themselves.
B be the event that an Internet user posts photos taken by themselves.
P(A) = 0.47
P(A) = 0.28
P(A or B) = [tex]P(A\cup B)[/tex] = 0.52
To find:
Conditional probability that an Internet user posts photos given that they post videos.
OR
P(A/B) = ?
Solution:
Formula to be used to find the required conditional probability:
[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}[/tex]
For this, [tex]P(A \cap B)[/tex] is required.
Formula
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
[tex]0.52=0.47+0.28-P(A\cap B)\\\Rightarrow P(A\cap B)=0.23[/tex]
Now, the required conditional probability is:
[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}\\\Rightarrow P(A/B) = \dfrac{0.23}{0.28}\\\Rightarrow \bold{P(A/B)} = 0.82}[/tex]
So, the answer is 0.82.

Step-by-step explanation:
Task #4: Waiting in Line You’re attending a concert with five friends but each of you arrived at the venue at different times. The fractions below tell how much of the distance they have already moved since they got in line. (Think about fractions as area models if you need some help!) You 3 / 4 Andrea 1/ 2 Bart 4 /5 Camden 7 /8 Drake 3/ 7 Ethan 2 /3 1. Who do you know is not going to get in the gate first? 2. How do you know? 3. Who is getting in the gate first? Who is getting in the gate last?
Step-by-step explanation:
Given data:
You = 3/4
Andrea = 1/2
Bart = 4/5
Camden = 7/8
Drake = 3/7
Ethan = 2/3
1. Drake would not be getting into the gate first because he is far behind at 3/7.
2. each fraction represents how far each have travelled Or moved on the line. Just like how you have move 3/4 on the line which represents three quarter of the line, and Andrea has moved half way through the line at 1/2.
3. Camden 7/8 would get to the get first and Drake 3/7 would get in last.

Answer:
9/35 or 0.2571428
Answer:
9/35 (Already Simplified)
Step-by-step explanation:
For fraction multiplication, multiply the numerators and then multiply the denominators to get
4×97×20=36140
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 36 and 140 using
GCF(36,140) = 4
36÷4140÷4=935
Therefore:
47×920=935
Solution by Formulas
Apply the fractions formula for multiplication, to
47×920
and solve
4×97×20
=36140
Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(36,140) = 4
36÷4140÷4=935
Therefore:
4/7×9/20=9/35

Answer:
x=5
Step-by-step explanation:
well first 2(2x-5) turns to 4x-10 because of distributive prperty
then simplify the other side 3x+x-2x to 4x-2x to 2x
then subtract 4x from both sides and you get -10= -2x
after divied -2x/-2 and -10/-5
and get x=5
then plug in 5 into x to make sure both sides are equal
and they equal 10=10
Determine the slope of line (AB) and the slope of line (CD). Determine whether line (AB) and line (CD) are parallel, perpendicular, or just intersecting (neither). Points A and B line on the line y = 2/3x + 4. Points C and D line on the line 6x + 4y = 16.
Answer:
The slopes are perpendicular
Step-by-step explanation:
Points A and B line on the line y = 2/3x + 4.
This line is in the form
y = mx+b where m is the slope
The slope is 2/3
Points C and D line on the line 6x + 4y = 16.
Solve for y
6x+4y = 16
4y = -6x +16
Divide by 4
4y/4 = -6/4x + 16/4
y = -3/2 x +4
The slope is -3/2
The slopes multiply to -1
2/3 * -3/2 = -1
so they are perpendicular
What is the initial value of the following equation? Y=1/2x-4
You want to find out whether caffeine mitigates the effect of alcohol on reaction time. To study this, you administer to your subjects a drink that is equivalent to three 12-ounce beers, followed by the equivalent of two cups of coffee. Then your subjects complete a simulated driving task in which they must follow a fixed speed limit while driving on a straight road. Wind periodically and randomly pushes the simulated vehicle right, left, or not at all. Speed is measured in miles per hour above or below the 60-mph speed limit, with 1 mph being the smallest unit on the scale. Suppose the first subject scores 9 mph. Determine the real limits of 9. When measuring weight on a scale that is accurate to the nearest 0.2 pound, what are the real limits for the weight of 120 pounds? When measuring weight on a scale that is accurate to the nearest 0.5 pound, what are the real/limits for the we.ght of 187 pounds?
Answer:
First Question
lower limit of 9 mph [tex]j = 8.5 \ mph[/tex]
upper limit of 9 mph [tex]q = 9.5 \ mph[/tex]
Second Question
lower limit of 120 pounds is [tex]i = 119.9 \ pounds[/tex]
upper limit of 120 pounds is [tex]l = 120.1 \ pounds[/tex]
Third Question
lower limit of 187 pounds is [tex]a = 186.75 \ pounds[/tex]
upper limit of 187 pounds is [tex]b = 187.25 \ pounds[/tex]
Step-by-step explanation:
From the question we are told that
The amount of beer administered is three 12-ounce beers
The amount of coffee administered is two cups of coffee
The speed limit is 60-mph
The smallest unit of scale is 1 mph
The first subject scores 9 mph
Generally given that the smallest unit of scale is 1 mph then the deviation of 9 mph will be by [tex]\frac{1}{2} \ mph[/tex]
Hence the lower limit of 9 mph is
[tex]j = 9 - 0.5[/tex]
[tex]j = 8.5 \ mph[/tex]
And the upper limit of 9 mph is
[tex]q = 9 + 0.5[/tex]
[tex]q = 9.5 \ mph[/tex]
Generally given that the measuring weight on a scale that is accurate to the nearest 0.2 pound then 120 pounds will deviate by [tex]\frac{1}{0.2} \ pounds[/tex]
Hence the lower limit of 120 pounds is
[tex]i = 120 - 0.1[/tex]
[tex]i = 119.9 \ pounds[/tex]
And the upper limit of 120 pounds is
[tex]l = 120 + 0.1 [/tex]
[tex]l = 120.1 \ pounds[/tex]
Generally given that the measuring weight on a scale that is accurate to the nearest 0.5 pound then 187 pounds will deviate by [tex]\frac{1}{0.5} \ pounds = 0.25 \ pounds [/tex]
Hence the lower limit of 120 pounds is
[tex]a = 187 - 0.25[/tex]
[tex]a = 186.75 \ pounds[/tex]
And the upper limit of 120 pounds is
[tex]b = 187 + 0.25 [/tex]
[tex]b = 187.25 \ pounds[/tex]
Caffeine migrates the effects of alcohol.
Caffeine being a drug in itself is able to remove the effects of alcohol drugs. In order to study the effects of drinking coffee can be used to cure and treat the patients suffering.
Thus caffeine has more medicinal usage.
The study administered to the subject that drink coffee equivalent to three 12 ounces of beer was taken in 2 cups of coffee. The subjects were asked to do driving takes which has some mixed reactions.The goal was to find a cause-and-effect relationship. The study proves that the caffeine kept them more awake as per the use of alcohol of the beer.Hence as per the effect of chemicals, the effects of weights increased. Thus was able to migrate the reaction time.Learn more about whether caffeine.

Which equation can be used to graph the line that passes through (6,15) and is perpendicular to the graph y-7= 1/2 (x+2)
Answer:
Option A. y = –2x + 27
Step-by-step explanation:
y – 7 = ½(x + 2)
We'll begin by calculating the slope of the equation above. This can be obtained as follow:
y – 7 = ½(x + 2)
Clear bracket
y – 7 = ½x + 1
Rearrange
y = ½x + 1 + 7
y = ½x + 8
Comparing
y = ½x + 8
with
y = mx + c
The slope (m) = ½
Next, we shall determine the slope (m2) of the equation perpendicular to the line. This can be obtained as follow:
For perpendicularity,
m1 × m2 = –1
m1 = ½
½ × m2 = –1
m2 /2 = –1
Cross multiply
m2 = 2 × –1
m2 = –2
Therefore, the slope of the equation perpendicular to the line is –2
Finally, we obtained the equation of the line as follow:
Coordinate = (6, 15)
x1 coordinate = 6
y1 coordinate = 15
Slope (m) = –2
y – y1 = m(x – x1)
y – 15 = –2(x – 6)
Clear bracket
y – 15 = –2x + 12
Rearrange
y = –2x + 12 + 15
y = –2x + 27
Therefore, the equation is y = –2x + 27

kest kuy is offering a sale on its laptop computers with a 20 percent discount off its original price. there is 8% sales tax added to the discounted price to get the final price of the computer. if x is the original price and y is the final price, write an equation to determine the final price based upon the original price.
Answer:
[tex]y = 0.88x[/tex]
Step-by-step explanation:
Given
[tex]Discount = 20\%[/tex]
[tex]Sales\ Tax = 8\%[/tex]
Required
Determine the final price
First, we need to determine the sales price after the discount.
[tex]Discount = 20\% * x[/tex]
[tex]Discount = 0.20 * x[/tex]
[tex]Discount = 0.20x[/tex]
[tex]Sales\ Price = x - Discount[/tex]
[tex]Sales\ Price = x - 0.20x[/tex]
[tex]Sales\ Price = 0.80x[/tex]
Next, is to determine the sales tax.
[tex]Sales\ Tax = 8\% * x[/tex]
[tex]Sales\ Tax = 0.08 * x[/tex]
[tex]Sales\ Tax = 0.08x[/tex]
Final Price, y is then calculated as thus:
[tex]y = Sales\ Price + Sales\ Tax[/tex]
[tex]y = 0.80x + 0.08x[/tex]
[tex]y = 0.88x[/tex]
