The bumper car ride at the state fair has 3 red cars, 4 green cars, and 5 blue cars. Michelle is first in line for the ride and is assigned a car at random. Garth is next in line and is randomly assigned a car. What is the probability that both Michelle and Garth will drive a red bumper car? Express your answer as a percent. If necessary, round your answer to the nearest tenth.
25%
6.3%
95.5%
4.5%
Answer:
25%
Step-by-step explanation:
so you will add 4,3,5=12
3/12=0.25 then = 25%
The probability that both Michelle and Garth will drive a red bumper car is calculated as; 4.5%
What is the Probability?We are told that;
Number of red cars = 3 red cars
Number of green cars = 4 green cars.
Number of blue cars = 5 blue cars.
Total Number of Cars = 3 + 4 + 5
Total number of Cars = 12 cars
Probability that Michellewill drive a red bumper car is;
P(A) = 3/12
Probability that Garth will drive a red bumper car is;
P(B) = 2/11
Probability that both Michelle and Garth will drive a red bumper car is;
P(A ∩ B) = (3/12) × (2/11)
P(A ∩ B) = 0.045 = 4.5%

Herman is traveling 125 miles from his house to the beach by car. Herman plans to stop for lunch when the ratio of the distance he has traveled to the distance he still has to travel is 2:3. What distance will Herman have traveled when he stops for lunch?
Answer:
250 miles
Step-by-step explanation:
The given distance between the house and the beach is 125 miles.
Let [tex]x[/tex] miles be the distance between the house and the lunch stop.
So, at the time of the lunch stop, he already traveled [tex]x[/tex] miles, the remaining distance is the distance between the lunch stop and the beach.
Let [tex]y[/tex] miles be the remaining distance, so
[tex]y=125-x.[/tex]
Give that the ratio of the distance he has traveled, [tex]x[/tex], to the distance he still has to travel, [tex]y[/tex], is [tex]2:3[/tex],i.e
[tex]x:y=2:3[/tex]
[tex]\Rightarrow \frac x y =\frac 2 3[/tex]
[tex]\Rightarrow \frac {x}{125-x}=\frac 2 3[/tex]
[tex]\Rightarrow 3\times x=2\times(125-x)[/tex]
[tex]\Rightarrow 3\times x=2\times125-2\timesx[/tex]
[tex]\Rightarrow 3 x=250-2x[/tex]
[tex]\Rightarrow 3x-2x=250[/tex]
[tex]\Rightarrow x=250[/tex]
Hence, the distance traveled by Herman when he stops for lunch is 250 miles.
Natalie is responsible for supplying drinking water for each member of the football team during all the games they play at her school. She knows that they will play a total of 12 games at the school and that there are 15 players on the team. She figures that each player will drink 2 bottles of water during each game. What would be a good first step for Natalie to perform when solving this problem?
Answer:
360 bottles.
Step-by-step explanation:
the first step i would start off with is getting the number of bottles needed, which is the 12 games, times the 2 per game, which gives us 24 bottles. so if 24 bottles are needed for one player, we can figure out the total number of bottles needed by multiplying 24 bottles per player, by the 15 players and we get 360 bottles of water.

5 times a number, increased by 2
less than twice the number, is 40.
Find the number.
Answer:
21/5 or 4.2
Step-by-step explanation:
we need to repeat the steps backward.
"increased by 2 than less than twice the number"
we need to add 2 to 40 and divide by 2 . (40+2)/2 = 21. "5 times a number"the previous result has to be divided by 5.
(21)/(5) = 21/5 = 4.2
Proof:
"5 times a number, increased by 2
less than twice the number, is 40."
2( 5( 21/5 ) ) - 2 =2( 21 ) - 2 = 42-2 = 40

Which statement describes a process to solve square root b plus six minus square root b =5 Add a radical term to both sides and square both sides only once. Add a constant term to both sides and square both sides only once. Add a radical term to both sides and square both sides twice. Add a constant term to both sides and square both sides twice.
Answer:
Add a radical term to both sides and square both sides twice.
Step-by-step explanation:
Given the radical equation
√(b+6) - √b = 5
We are to evaluate the expression for the value of b
Step 1: Add the radical term √b to both sides
√(b+6) - √b +√b = 5+√b
√(b+6) = 5+√b.
Step 2: Square both sides of the equation
(√(b+6))² = (5+√b.)²
b+6 = 25+10√b+ (√b)²
b+6 = 25+10√b + b
Step 3: collect like terms
b+6-b-25 = 10√b
-19 = 10√b
Step 4: square both sides of the resulting equation
(-19)² = (10√b)²
361 = 100b
b = 361/100
b = 3.61
Based on the calculation above, the correct option is C.
Add a radical term to both sides and square both sides twice.
Answer:
C

Using the following function, explain how the following features (asymptotes,
intercepts, holes) can be identified/constructed in the graph.
3(2-3)(x+2)(x-4)/8(6+9) (2-3)
The given asymptote, intercepts and holes of the given function depends
on the numerator and denominator of the function from which we have;
The vertical asymptote is the line x = -9The x-intercept occurs at the points, x = -2, and x = 4, the y-intercept is located at the point at which y = [tex]-\dfrac{1}{3}[/tex]The hole is at the point (3, 0)How can the properties of the function be found?The given function is presented as follows;
[tex]f(x) = \mathbf{ \dfrac{3 \cdot (x - 3) \cdot (x + 2) \cdot (x - 4)}{8 \cdot (x + 9) \cdot (x - 3)}}[/tex]
Given that there is a common factor of (x - 3) in the numerator and the denominator, we have;
[tex]f(x) = \mathbf{\dfrac{3 \cdot (x + 2) \cdot (x - 4)}{8 \cdot (x + 9)}}[/tex]
The asymptote is obtained by equating the denominator to zero as follows;
8·(x + 9) = 0
x = -9
The asymptote is the line x = -9The intercepts is given by the points the x or y-value are zero, which gives;
[tex]At \ an \ intercept, \ f(x) = \dfrac{3 \cdot (x - 3) \cdot (x + 2) \cdot (x - 4)}{8 \cdot (x + 9) \cdot (x - 3)}= 0[/tex]
3·(x - 3)·(x + 2)·(x - 4) = 0
Therefore;
x = -2, x = 4 at the x-intercepts[tex]At \ the \ \mathbf{y-intercept}, \ f(0) = \dfrac{3 \cdot (0- 3) \cdot (0 + 2) \cdot (0 - 4)}{8 \cdot (0 + 9) \cdot (0 - 3)}= -\dfrac{1}{3}[/tex]
The hole is given by the point where the function is zero.
Placing (x - 3) = 0 in the denominator
Therefore;
A hole is the point x = 3Learn more about asymptotes and intercepts here:

Raul opened a savings account with $3,500 . Each week , x , raul pays the dog sitter $25 from his saving account. Write a function, f(x) , that is equal to the amount of money in the account after Raul pays the dog sitter each week .
Answer:
f(x) = -25d + 3,500
Step-by-step explanation:
Raul opened a savings account with $3,500.
Each week, Dale pays the dog sitter $25 from his saving account.
Let d be the number of weeks and f(x) be the function representing the amount of money in the account after Raul pays the dog sitter d weeks.
The amount of money in the Raul's account is decreasing each week by $25, then the slope of the linear function is
Initially, at week d=0, Raul's account has $3,500, so b=3,500.
Write the function's expression in the form
f(x) = md + b
Hence,
f(x) = -25d + 3,500
