Roxanne likes to fish. She estimates that 30% of the fish she catches are trout, 20% are bass, and 10% are perch. She designs a simulation.
Let 0, 1, and 2 represent trout.
Let 3 and 4 represent bass,
Let 5 represent perch.
Let 6, 7, 8, and 9 represent other fish.
The table shows the results:
The probability helps us to know the chances of an event occurring. The probability of Roxanne catching bass is 60%.
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]
For the next four of the fishes to be bass, the numbers in the table must contain the digit 3 or 4 in it. Therefore, the cases where Roxanne catches bass are:
263520534526699443483087832335793840683933637683Also, it is mentioned that the total number of cases is 20 (Given in the table). Therefore, the probability of catching a bass can be written as,
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}\\\\\\Probability=\dfrac{\text{Number of cases where Roxanne catches fish}}{\text{Total number of catches}}\\\\\\Probability = \dfrac{12}{20} = 0.60\\\\Probability = 60\%[/tex]
Hence, the probability of Roxanne catching bass is 60%.

Step-by-step explanation:
In the year 1985, a house was valued at $110,000. By the year 2005, the value had appreciated to $148,000. What was the annual growth rate between 1985 and 2005? Assume that the value continued to grow by the same percentage. What was the value of the house in the year 2010?
Answer:
The step by step explanation isn't your problem but it is a way to see how to do your problem
Step-by-step explanation:
This is an exponential growth equation, therefore, it follow the standard form:
where y is the value of the house after a certain number of years,
a is the initial value of the house,
b is the growth rate, and
x is the year number.
We are going to make this easy on ourselves and call year 1985 year 0. Therefore, is year 1985 is year 0, then year 2005 is year 20, and year 2010 is year 25. We will make these the x coordinates in our coordinate pairs.
(0, 113000) and (20, 155000)
Filling into our standard form using the first coordinate pair will give us the initial value of the house at the start of our problem:
Anything raised to the 0 power is equal to 1, so
113000 = a(1) and
a = 113000
Now we will use that value of a along with the second pair of coordinates and solve for b, the growth rate you're looking for:
Start by dividing both sides by 113000 to get a decimal:
To solve for b, we have to undo that power of 20 by taking the 20th root of b. Because this is an equation, we have to take the 20th root of both sides:
The 20th root and the power of 20 undo each other so all we have left on the right is a b, and taking the 20th root on your calculator of the decimal on the left gives you:
b = 1.0159 which rounds to
b = 1.02 This is our growth rate.
Now we can use this growth rate and the value of a we found to write the model for our situation:
If we want to find the value of the house in the year 2010 (year 25 to us), we sub in a 25 for x and do the math:
Raise 1.02 to the 25th power and get:
y = 113000(1.640605994) and multiply to get a final value of
y = $185,388

The depth of an underwater camera on a cable anchored to the sea floor is proportional to the time. The table records the time in seconds (s) and depth in meters (m) of the camera. What are the missing values in the table?
Answer:
20=-1
60=-3
100=-5
240=-12
Step-by-step explanation:
divide time and depth by 20
When time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
The depth of an underwater camera on a cable anchored to the sea floor is proportional to the time.
From the table let us take the values of time and depth which both are given.
Time=100 and depth is -5.
From this we can find the other values.
Depth=-1 when time is x
100/-5=x/-1
100=5x
Divide both sides by 5
x=20
So when time is 20 the depth is -1.
Now we have to find the depth when time is 60.
60/x=100/-5
-300=100x
x=-3
So when time is 60 the depth is -3.
Now we have to find the depth when time is 240.
240/x=100/-5
-1200=100x
Divide both sides by 100
x=-12
when time is 240 the depth is -12.
Hence, when time is 20 the depth is -1, when time is 60 the depth is -3 and time is 240 the depth is -12.

The Montgomery Company tells Squeaky Clean that most of their buildings are 40 feet tall. Squeaky Clean decides to use ladders to reach the upper windows. The base of the ladder works best on the sidewalk so it needs to be 9 feet away from the building. How tall should the ladder be in order to reach the top of the building?
Answer: 41 feet
Step-by-step explanation: The ladder, the building and the sidewalk creates a right triangle, with the 90° formed at the junction of sidewalk and building, so the length of the ladder is the triangle's hypotenuse.
To determine hypotenuse, use Pythagorean's theorem:
[tex]h^{2}=s^{2}_{1}+s^{2}_{2}[/tex]
[tex]h=\sqrt{40^{2}+9^{2}}[/tex]
[tex]h=\sqrt{1681}[/tex]
h = 41
For the ladder to reach the top of the building, it has to be 41 feet tall.
a line contains the points (0,-3) and (-8,-9)which of the following represents the equation of the line?
A. y= -0.75x - 3
b. y=6x - 8
c. y=0.75x - 3
d. y=4/3x - 5
Answer: C. y = 0.75x - 3
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
Slope = -9 - (- 3) / -8 - 0 = -9 + 3/ -8 - 0 = -6/-8 = 0.75
Y-intercept = -3
y = 0.75x + (- 3)
y = 0.75x - 3

A video game is on sale for 20% off. The sale price of the game is $35.00. How much did the game ORIGINALLY cost?
Answer:
$43.75
Step-by-step explanation:
To find how much the game would have been 20% off from 43.75, you would have needed the expression
43.75*0.8
So to go from 35 to 43.75, you need the expression
35/0.8.
This expression in simpler terms means What is 38, 80% of?
That is how we get 43.75.
35/0.8 = 43.75.

Han used 1 1/2 gallons of paint to paint 3/5 of a shed. How many gallons of paint will it take to paint the whole shed? Write a multiplication equation or a division equation to represent this situation then find the answer. Show your reasoning
Answer:
2 gallons
Step-by-step explanation:
If Han used 1 1/2 gallons of paint to paint 3/5 of a shed, this can be expressed as;
1 1/2 gallons = 3/5 of the shed
3/2gallons = 3/5 of the shed
To find the number of gallons that will paint the whole shed, we will say;
x gallons = 1 shed
Divide both expressions
3/2/x = 3/5
3/2x = 3/4
2x * 3 = 3*4
6x = 12
x = 12/6
x = 2
Hence 2 gallons will be needed for the whole shed

Evaluate ƒ(x) when x = 3. 6x^2+2
Answer: f(x)=56
Step-by-step explanation:
We are given the equation f(x)=6x²+2. Since we are asking for x=3, we can plug that into the equation and solve.
f(3)=6(3)²+2 [exponent]
f(3)=6(9)+2 [multiply]
f(3)=54+2 [add]
f(3)=56
Now, we know that f(x)=56 when x=3.

A deli sells 2 hot dogs for $2.50. What is the constant of proportionality of dollars per hot dog?
Answer:
$1.25 per hot dog
Step-by-step explanation:
Since we have given that
A deli sells 2 hot dogs for $2.50
i.e.
Cost of 2 hot dogs = $2.50
And we need to find the constant of proportionality of dollars per hot dog, for which we'll use unitary method.
So,
Cost of 1 hot dog is given by
2.50/2=$1.25
So, Cost of per hot dog is $1.25.
