Answer: 18 miles
12 ÷ 4 = 3. So, we must multiply 3 by 6 to find how much Joe walks for 6 trips to school.
-------------------------------------------------------------------------------------------------------------------------
Now, we must multiply the number 6 by 3.
6 x 3 = 18
-------------------------------------------------------------------------------------------------------------------------
Answer = 18
Answer:
18 miles
Step-by-step explanation:
We can write ratios to solve
12 miles x miles
---------- = ------------
4 trips 6 trips
Using cross products
12 *6 = 4x
72 = 4x
Divide by 4
72/4 = 4x/4

Answer:
x = 8
Step-by-step explanation:
Given
3(x + 1) + 6 = 33 ( subtract 6 from both sides )
3(x + 1) = 27 ( divide both sides by 3 )
x + 1 = 9 ( subtract 1 from both sides )
x = 8

Only 0.1% of the individuals in a certain population have a particular disease (an incidence rate of 0.001). Of those who have the disease, 95% test positive when a certain diagnostic test is applied. Of those who do not have the disease, 90% test negative when the test is applied. Suppose that an individual from this population is randomly selected and given the test: a) Calculate P(positive test) b) Calculate P(has disease | positive test)
We're given
P(has disease) = 0.001
P(positive test | has disease) = 0.95
P(negative test | does not have disease) = 0.90
(a) By the law of total probability,
P(positive test) = P(positive test AND has disease) + P(positive test AND does not have disease)
Recall that the probability of an event A conditioned on another event B is
P(A | B) = P(A AND B) / P(B)
so that
P(positive test) = P(positive test | has disease) * P(has disease) + P(positive test | does not have disease) * P(does not have disease)
P(positive test) = 0.95 * 0.001 + (1 - 0.90) * (1 - 0.001)
P(positive test) ≈ 0.10
(b) From the definition of conditional probability, we hvae
P(A | B) = P(A AND B) / P(B) = P(B | A) P(A) / P(B)
so that
P(has disease | positive test) = P(positive test | has disease) * P(has disease) / P(positive test)
P(has disease | positive test) = 0.95 * 0.001 / 0.10
P(has disease | positive test) ≈ 0.0094
The probability will be "0.017699".
Given:
Incident rate,
0.1% or 0.001[tex]P(D) = 0.001[/tex][tex]P(D')= 1-0.001[/tex][tex]= 0.999[/tex]
[tex]P(\frac{P}{D} ) = 0.95[/tex][tex]P(\frac{N}{D} ) = 0.9[/tex]Now,
→ [tex]P(\frac{N}{D'} ) = 1-P(\frac{N'}{D'} )[/tex]
[tex]= 1-0.95[/tex]
[tex]= 0.05[/tex]
then,
→ [tex]P(\frac{D}{N} ) = \frac{Pr(D)\times P(\frac{N}{D} )}{P(N)}[/tex]
or,
[tex]= \frac{Pr(D)\times P(\frac{N}{D} )}{P(D) \ P(\frac{N}{D} )+P(D') \ P(\frac{N}{D'} )}[/tex]
By substituting the above values, we get
[tex]= \frac{0.001\times 0.9}{0.001\times 0.9+0.999\times 0.05}[/tex]
[tex]= \frac{0.0009}{0.0009+0.04995}[/tex]

Raul works at a movie theatre. The function f(x) represents the amount of money Raul earns per ticket, where x is the number of tickets he sells. The function g(x) represents the number of tickets Raul sells per hour, where x is the number of hours he works. Show all work to find f(g(x)), and explain what f(g(x)) represents.
f(x) = 2x2 + 16
g of x equals the square root of the quantity 5 x cubed
Answer:
Step-by-step explanation:
Given f(x) = 2x²+16
g(x) = √5x³
First is to get the composite function f(g(x))
f(g(x)) = f(√5x³)
To get f(√5x³), we will replace x in f(x) with √5x³ as shown:
f(√5x³) = 2(√5x³)²+16
f(√5x³) = 2(5x³)+16
f(√5x³) = 10x³+16
Hence f(g(x)) = 10x³+16
f(g(x)) will be the function of amount earned by Raul for the total number hour he works
Answer:
10x^3 dollars/hour

Please help! Brainliest! How are the functions y = 2x2 and y = 2x2 + 7 related? How are their graphs related?
A. Each output for y = 2x2 + 7 is 7 less than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated down 7 units.
B. Each output for y = 2x2 + 7 is 7 greater than the corresponding output of y = 2x2. The graph of y = 2x2 + 7 is the graph of y = 2x2 translated up 7 units.
Option B is correct.
We have the two equations -
[tex]y= 2x^{2}[/tex]
[tex]y=2x^{2} +7[/tex]
We have determine how are these functions related and how are their graphs related.
What type of conic section is represented by equation -y = [tex]$x^{2}[/tex] ?A parabola is represented by the equation y = [tex]$x^{2}[/tex].
According to the question, we have -
[tex]y= f(x) = 2x^{2}[/tex]
[tex]y=g(x)=2x^{2} +7[/tex]
Refer to the image attached for graphs.
Now -
g(x) - f(x) = [tex]2x^{2} +7-2x^{2}[/tex] = 7
Therefore - Each output for y = g(x) is greater than the corresponding output of y = f(x).
From the graph it is clear that the graph of y = g(x) is the graph of
y = f(x) translated up 7 units.
Hence, Option B is correct.

2.5/6 = h/9 h=? What does this mean
Answer:
h = 3.75
Step-by-step explanation:
Step 1: Write equation
2.5/6 = h/9
Step 2: Solve for h
Cross multiply: 22.5 = 6hDivide both sides by 6: 3.75 = hRewrite: h = 3.75Step 3: Check
Plug in h to verify it's a solution.
2.5/6 = 3.75/9
0.416667 = 0.416667
Answer:
h = 3.75
Step-by-step explanation:
Given
[tex]\frac{2.5}{6}[/tex] = [tex]\frac{h}{9}[/tex] ( to solve for h, cross- multiply )
6h = 22.5 ( divide both sides by 6 )
h = 3.75

A fruit seller has 3 crates of apples. Each crate has 100 apples. If he packed 6 apples in 1 box. Which of these gives the number of such boxes needed to pack all the apples.
100 x 6
300x6
100 divided by 6
300 divided by 6
Answer:
300 divided by 6
Step-by-step explanation:
Given that;
Number of crates of apple owned by fruit seller = 3 crates
Number of apples in each crate = 100 apples
He packed 6 apples in 1 box;
Unknown:
Number of boxes needed to pack all the apples = ?
This problem is pretty straight forward;
Number boxes needed to pack all apples = [tex]\frac{Number of crates owned by fruit seller x number of apples per crate}{Number of apples per box}[/tex]
Input the parameters and solve;
Number of boxes need to pack all apples = [tex]\frac{100 x 3}{6}[/tex] = [tex]\frac{300}{6}[/tex]
So the solution is 300 divided by 6

Jack drove to the train station and back. It
took two hours less time to get there than
it did to get back. The average speed on
the trip there was 40 km/h. The average
speed on the way back was 24 km/h. How
many hours did the trip there take?
Answer:
8hoursStep-by-step explanation:
let the time taken to get back be x
so that the time needed to go is (x-2)
we know that speed= distance/time
therefore the speed for the return is 24 km/h.
distance (return)= 24*x
distance (return)=24x
therefore the speed to the station is 40 km/h.
distance (return)= 40*(x-2)
distance (return)=40x-80
We know that the distance is the same
24x=40x-80
24x-40x=-80
16x=80
divide both sides by 16
x=5
the time taken to get back is x=5hours
the time taken to is x-2=(5-2)= 3hours
the total trip takes 3+5= 8hours
How many boys are there in a group of 27 students if there are four-fifths as many girls as there are boys?
Answer:
15 boys
Step-by-step explanation:
There are 27 students. The number of girls is only 4/5 of the number of boys. I started by splitting the class. 14 boys and 13 girls doesn't work, so I changed it to 12 and 15. If it was 12 girls and 15 boys, the girls would have 4/5 of the boys, so it must be 12 girls and 15 boys.

A leatherback sea turtles was swimming at 850 below sea level. He went 165 meters and then descendes 165 meters. Draw a number line to show the change in position of the sea turtles from depth it was swimming. What integer represents the sea turtles change in position?
Answer:
The answer is below
Step-by-step explanation:
a) Let negative means the turtle position when descending and positive for going up. Therefore since the turtle was 850 meters below see level, it was at -850. It then moves 165 meters up, hence its new position is -685 meters (-850 + 165). Lastly it moves down 165 meters, hence its new position is -850 meters (-685 - 165)
b) The change in position is the sum of the movements = +165 - 165 = 0 meters.

The price of fancy coffee has increased 9% each year for the last several years.
If the current cost $8 per pound, what did a pound cost two years ago
Answer:
$6.56
Step-by-step explanation:
First, take 8 and divide it by 100. Then you have 0.08. multiply that by 9. You get 0.72, that is how much the price increases every year. multiply that by 2, and you get 1.44. subtract 1.44 from 8, and you are left with $6.56, the price it was two years ago.
