A carnival has a duck-pond booth. You choose a rubber duck at random. The mark on the bottom of the duck tells you whether you won a small, medium, or large prize, or no prize at all. There are 56 ducks floating in the pond. There are 5 ducks marked as large-prize winners, 10 ducks marked as medium-prize winners, and 20 ducks marked as small-prize winners. Find the theoretical probability of winning a small prize at the duck pond. Express your answer as a percent. If necessary, round your answer to the nearest thousandth.
35.714%
62.5%
280%
64.286%
The probability helps us to know the chances of an event occurring. The probability of winning a small prize in the carnival is 35.714%.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
Given that there is a total of 56 ducks floating in the pond, out of which 20 ducks are marked as small-prize winners. Therefore, the probability of winning a small price can be written as:
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\\rm Probability=\dfrac{\text{Nnmber of small price ducks}}{\text{Total number of ducks}}\\\\\\Probability = \dfrac{20}{56} = 0.35714 = 35.714\%[/tex]
Hence, the probability of winning a small prize in the carnival is 35.714%.

Choose 1 answer:
Answer:
Answer choice A is the correct answer
Step-by-step explanation:
** Before you start: If anything that is < or > you shouldn't fill in the plot.
If it has ≤ or ≥then you need to fill in the plot.**
Terminology:
(>) : Greater than (Don't fill in)
(<): Less than (Don't fill in)
(≤) : Less than or equal to (Fill in)
(≥) : Greater than or equal to (Fill in)
In this case, the answer choices C and D are wrong automatically.
Your Inequality:
11g + 5 ≤ 49
Subtract 5 both sides
11g ≤ 49-5

If the slope of a line is undefined, does the line rise (from left to right), fall (from left to right), horizontal or vertical?
Answer:
Vertical.
Step-by-step explanation:
Slope judges the vertical angle in which the line is moving, from point to point. If the line is vertical in it of itself, there will be no specific point in which you can use to define the slope. The denominator of run is always 0, and having a 0 for denominator will result in the fraction being undefined. You cannot have parts of nothing, mathematically.
Vertical. Please consult the explanation for more details.
Solution:If the line's slope is undefined, then the line is vertical.Lines with an undefined slope have a run of zero.Remember one of the formulae for slope: Rise/Run.If the run is zero, the slope is undefined.You should be cognisant of the fact that division by zero is undefined. If not, please do not worry. Let me explain what the run is. The run is the amount of units we move left or right, or "run".The rise is the quantity of units we move up and down, or "rise".Hope it helps.

A right triangle has an area of 33 mm2 and a height of 12mm. How long is the base of the triangle
Answer:
5.5
Step-by-step explanation:
Special Triangle: Solve for x and y.
Answer:
x = 8.67 and y = 10
Step-by-step explanation:
In right angled triangle
cos 60⁰ = 5/y
1/2 = 5/y
y = 10
in right angled triangle,
tan 60⁰ = x/5
√3 = x/5
x = 5√3 = 5 × 1.73 = 8.65
x = 8.67
A base of a trapezoid is 16 feet, and the height is 3 feet. The area of the trapezoid is 36 square feet. Find the length of the other base
Answer:
8 feet
Step-by-step explanation:
Area of a trapezoid: h(a + b)/2
height, h = 3 ft
base 1, a = ?
base 2, b = 16 ft
area, A = 36 ft^2
36 = 3(a + 16)/2
72 = 3(a + 16)
24 = a + 16

pls need help in math<3
Answer: 12 minutes
Step-by-step explanation:
Time taken by 2 people = 60 minutes
The time taken by 1 person is double that = 60 x 2 = 120 minutes
So the time taken by 10 people = 120 minutes / 10 people = 12 minutes
Answer: 12 minutes.
Step-by-step explanation: For two people, it takes an hour to paint a fence. With ten people, however, it takes very little time to paint a fence. 10 people are 5 times more people than when you have only 2. It would only take 12 minutes because it takes 5 times less time with 10 people than with only two.

Write in slope intercept form an equation of the line that passes through (-2,5),(-1,1)
Answer:
y=-4x-3
Step-by-step explanation:
Hi there!
We are given the following two points: (-2,5) and (-1,1)
We want to write the equation of the line that passes through these two lines in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept
First, let's find the slope
The formula for the slope (m) calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything we need to calculate the slope, but let's label the value of the points to avoid any confusion
[tex]x_1=-2\\y_1=5\\x_2=-1\\y_2=1[/tex]
Now substitute into the formula
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{1-5}{-1--2}[/tex]
Simplify
m=[tex]\frac{1-5}{-1+2}[/tex]
Subtract
m=[tex]\frac{-4}{1}[/tex]
Divide
m=-4
Now substitute -4 as m into the equation:
y=-4x+b
Now we need to find b
As the equation passes through both (-2, 5) and (-1, 1), we can use either point to help solve for b.
Taking (-2,5) for example:
Substitute -2 as x and 5 as y:
5=-4(-2)+b
Multiply
5=8+b
Subtract 8 from both sides
-3=b
Substitute -3 as b.
y=-4x-3

144 Inches or 12 Feet
Step-by-step explanation
7 feet converted to inches is 84 So 84+60=144
And if you convert 60 inches into feet it would be 5
Answer:
144 inches
Step-by-step explanation:
1 ft = 12 inches
7 ft = 12 x 7 inches
7ft = 84 inches
Ice path you are floating on = 84 inches
other ice path = 60 inches
all together = 84 + 60

What is the range of the function f(x) = 3x2 6x – 8?
The domain of the function is a real number and the range of the function will be (-11, ∞).
What are domain and range?The domain means all the possible values of the x and the range means all the possible values of the y.
The function is given below.
f(x) = 3x² + 6x – 8
The range of the function will be
f(x) = 3x² + 6x – 8
f(x) = 3x² + 6x + 3 – 11
f(x) = 3(x² + 2x + 1) – 11
f(x) = 3(x + 1)² – 11
Then the range of the function will be from -11 to infinity.

There are 23 pennies on one side of a balance and 17 pennies on the other
side. Levi thinks 3 pennies should be added to the higher pan, Arjan thinks 4
Pennies should be added, and Charlotte thinks 6 pennies should be added. Who Is correct and why?
To have the same number of pennies in both sides, we should add 6 pennies, so Charlotte is correct.
How many pennies should we add?We want to have the same number of pennies on both sides, on one side we have 23 pennies, and in the other 17. So we will add x pennies to the last side, such that we get:
23 = 17 + x
This is a linear equation. To solve it, we need to isolate the variable x, we can do that by subtracting 17 in both sides:
23 - 17 = 17 + x - 17
6 = x
This means that the solution is 6, so we should add 6 pennies, meaning that Charlotte is correct.

Answer:
Option 1: 43π feet
Step-by-step explanation:
We are given that:
encloses garden with circular fence
garden measures 43 feet across = diameter
To find how much fencing is needed, we have to find the cicumference of the circular fence using the formula:
C = 2πr
C = Circumference
r = radius = half the diameter
We are given the diameter, so we just do half of it to get the radius
43 ÷ 2 = 21.5
r = 21.5
Now we substitute this into the formual:
C = 2πr
Substitute radius into formula
C = 2π(21.5)
Multiply 2 and 21.5
C = 43π
