In an aquarium, there are large fish and small fish. Half of the small fish are red.
One fish is selected at random. Find the probability that it is a small, red fish.
Write your answer as a fraction in simplest form.

Answers

Answer 1

The probability that it is a large, blue fish is 21%.

What is probability?

Probability is the mathematical study of outcomes in uncertain situation. It is used to describe the likhood of an event occurring and it can be expressed as a number between 0 to 1. Probability is used to quantify the uncertainty associated with any given event it helps us understand how likely it is that something will happen and it can be used to make prediction about futures even probability theory is it cornerstone of modern statistic and is widely used in field such as finance economics and science.

Here we have to use the definition of a simple probability, wherever all fishes has the same Probability to be chose.

So, we have to divided the possible of outcomes with the total of outcomes. The possible outcomes refer to the number of large-blue fishes, and the totals numbers of outcomes represent the total number of fishes. So

Therfore, there's 21% of chances to selected one fish randomly and be a large, blue fish.

Answers

2 more people like to swim than hike because 4 (the people who swim) minus 2 (the people who hike) is 2 people

The number of people who likes to swim than hike is given by the equation A = 2 people

What is an Equation?

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It demonstrates that the expressions on the left and right sides are connected in the same way.

An equation has components like as coefficients, variables, operators, constants, terms, expressions, and the equal to sign. The "=" sign and terms on both sides are required when generating an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number of people who likes to swim be s= 4 people

Let the number of people who likes to hike be h = 2 people

Let the number of people who likes to bike be b = 3 people

Now , the equation will be

The number of people who likes to swim than hike A = number of people who likes to swim - number of people who likes to hike

The number of people who likes to swim than hike A = s - h

The number of people who likes to swim than hike A = 4 - 2

The number of people who likes to swim than hike A = 2 people

Hence , the number of people who likes to swim than hike is A = 2 people

Use I = PRT to solve.
(time is in years)
1 = $312.50
R = 25%
T = 0.25 years
Find P.

Please help :)) for 35 points !

Answers

Answer:

Step-by-step explanation:

I = PRT

PRT = I

P = I/RT

P = 312.50/(.25)(.25)

P = 312.5/.0625

P= $5000

Principal for the given interest, rate of interest and time period is $5000.

Given that, I = $312.50, R = 25% and T = 0.25 years.

What is the simple interest?

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.

Now, SI=(P × R × T)/100

312.50= (P × 25 × 0.25)/100

⇒ P × 25 × 0.25 = 31250

⇒ P = 31250/6.25

⇒ P = $5000

Therefore, principal for the given interest, rate of interest and time period is $5000.

b + d = 500

Step 3: Rewrite Systems

b + d = 500

Equations

x + y = 500                   (1)

7x + 8y = 3800               (2)

Solution

There are two ways you could do this. You can use substitution or you could use multiplying equation 1 by either 7 or 8 to get rid of the x or y.

Multiply (1) by 7

7x + 7y = 3500             (3)       Write equation (2) below (3) and subtract

7x + 8y = 3800                        Subtract

    -y = - 300                            Multiply by - 1

     y = 300

Use the result for y to get x using equation 1

x + y = 500

x + 300 = 500                         Subtract 300

x = 500 - 300

x = 200

Stuffed bears = 200

PLS HELP MEEEEEE IM SO STUCK

Answers

Answer:

497 inches²

Step-by-step explanation:

Hi!

I have never done a problem like this in my life but I see exactly how it is meant to be solved. Lets try it out.

Let us first remind ourselves of the formulas we need for this.

Formula for a circle and the formula for a triangle.

Circle :

A = [tex]\pi[/tex] x r²

(or Area = pi x radius²) (Note that [tex]\pi[/tex] = 3.14)

Triangle :

A = b x h x 1/2

(or Area = base x height x 1/2)

Now lets see what the question wants from us and what we are given :

Gives us :

Diameter XY = 30 inches

YZ = 20 inches

XZ = 21 inches

And it wants the total area of the shaded regions to the nearest square inch. (Inches²)

Alright so first lets solve this triangle :

We need to do Base x Height x 1/2 :

Input your numbers given :

Base = 21in

Height = 20in

And lets multiply this out :

Base x Height x 1/2

21     x    20     x 1/2

21 x 20 gives us 420

Now we have :

420 x 1/2

Note that this is literally saying it wants half of 420. So we can actually just make it easier and do :

420/20

This gives us 210.

Great! Now we have the area of the triangle which is 210, this will be important later but for now lets move onto the circle.

Alright so we need radius to solve this but it really doesn't give us much about the circle.

But...

If you take a look at ∠YX you can see that it says 30in. This is actually the diameter of the circle and we can use this to find the radius of the circle.

The radius of a circle is 1/2 of the diameter.

And the diameter of a circle is 2 × the radius.

So in this case to find the radius we can actually take the 30inch diameter and divide it by 2 to find our radius.

30/2

=

15

Radius = 15inches!

Now lets look back to our wonderful circle formula.

A = [tex]\pi[/tex] x r²

or if we write it out :

Area = pi x radius²

So now lets plug in the radius we found and then solve to find the area of this circle.

Area = pi x 15²

(Don't forget the tiny 2 next to the 15!)

Now we can multiply this :

pi x 15²

=

706.858347058

Round to the nearest square inch :

707 inches²

(pi = [tex]\pi[/tex])

So now what we have is the area of both shapes. It is smooth sailing from this point on. Let us recap :

Triangle Area = 210 inches²

Circle Area = 707 inches²

Now we have to find the area of the shaded area which is really simple subtraction.

The shaded area is the circle but the triangle is overlapping this shaded area so all we have to do is subtract the triangles area from the circles area so all that will be left is the shaded area of the circle.

So we do :

Circles area - Triangles area = Our answer

707 - 210 = 497

There we go!

Our answer is 497 inches²

This took a minute I am sorry about that but I hope this helps!

how many after two years

Answer:

39 deers

51 deers

Step-by-step explanation:

The question can be expressed using the compounding rate formula:

A = P(1+r)^t

A = final population ; P = initial population ; rate, r = 30% = 0.3 ; t = time

After 1 year, t = 1

A = 30(1 + 0.3)^1

A = 30(1.3)^1

A = 39 deers

B.)

After 1 year, t = 2

A = 30(1 + 0.3)^2

A = 30(1.3)^2

A = 50.7

A = 51 deers approximately

Area of the composite figure,Divide the figure into small parts of different shapes.Add the areas of the divided figures.

Given composite figure is divided into two parts (1) triangle ABC (2) Rectangle DEFG

Area of ΔABC = [tex]\frac{1}{2}(AB)(BC)[/tex]

                        = [tex]\frac{1}{2}(5)[8-(1+2)][/tex]

                        = [tex]\frac{1}{2}(5)(5)[/tex]

Area of the composite figure = Area of triangle ABC + Area of DEFG

                                                = 12.5 + 40

To find the x- intercepts , let y = 0 , that is

6x - x² = 0 ← factor out x from each term

x(6 - x) = 0

Equate each factor to zero and solve for x

x = 0

6 - x = 0 ⇒ x = 6

Coordinates of P (6, 0 )

(b)

The axis of symmetry is a vertical line, positioned at the midpoint of the zeros

x = [tex]\frac{0+6}{2}[/tex] = [tex]\frac{6}{2}[/tex] = 3

Equation of axis of symmetry is x = 3

(c)

Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = 6x - x² = - x² + 6x ← is in standard form

with a = - 1, b = 6 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{6}{-2}[/tex] = 3

Substitute x = 3 into y = 6x - x² for y- coordinate

y = 6(3) - 3² = 18 - 9 = 9
