Pilate tagged 15 seals in the Columbia River. One month later, she spotted 6 of the tagged seals out of 20 seals spotted. What is an estimate for the size of the seal population in the Columbia River?

A.4 seals
B.25 seals
C.30 seals
D.50 seals

Answer and Step-by-step explanation:

The answer is A. 67.5.

We are told the scale factor of a model train is 1 inch to 13.5 feet.

We multiply the 5 inch model car by 13.5 to get the car size.

5 times 13.5 is 67.5.

Answer:

we have

1 inch :13.5ft

5in:=13.5×5=67.5ft

option A.67.5ft is a required answer.

Answer:

48

Step-by-step explanation:

Since 80 pupils is the total amount of pupils in Year 9...

5/5 = 80

1/5 = 80 ÷ 5 = 16

3/5 = 16 x 3 = 48 (The amount of pupils who said red is their favourite colour in Year 9)

Answer:

301.44 inches

Step-by-step explanation:

The spoke is from the center of the wheel to the edge, so its length is the radius, or 16 inches.

You want to find the distance that one rotation will take you, so you need the wheel's circumference.

Circumference = 2πr

2 x 3.14 x 16 = 100.48

100.48 inches is the distance of only 1 full rotation, so you just need to multiply 100.48 by 3 to get the distance of 3 rotations.

100.48 x 3 = 301.44

Answer:  16

Step-by-step explanation:

All you do is count the space in between 0 and 5 and then take that number and multiply it by itself.

Answer:

p = 37

Step-by-step explanation:

The most important step in beginning algebra is to get all the letters on one side and and all the numbers on the other. In This case it is only all the numbers that need to be transferred.

p - 24 + 24 = 13 + 24

p = 37

Answer:

Step-by-step explanation:

cut each of the long boards in half.    use a piece from each  cut.. for one triangle and the other two pieces of each cute,  for the next triangle.   Place the longest board on the hypotenuse.   then place the next board on one side of the triangle that is being made.   line the ends up with each other ...  so that the ends make the missing side form a right angle to the side board.  Maybe the protractor would help here some. To find the 90° angle.    Do the same with the other two pieces and the triangles will be congruent.   b/c the Hypotenuses are the same length and one of the sides are also the same length.  so then that makes them congruent triangles... hope that makes sense?  :/

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

Given

[tex]\sqrt x + \sqrt x = (4.4,4.5)[/tex]

Required

Find x

When the result is 4.4, we have:

[tex]\sqrt x + \sqrt x = 4.4[/tex]

This gives:

[tex]2\sqrt x = 4.4[/tex]

Divide both sides by 2

[tex]\sqrt x = 2.2[/tex]

Square both sides

[tex]x = 2.2^2[/tex]

[tex]x = 4.84[/tex]

When the result is 4.5, we have:

[tex]\sqrt x + \sqrt x = 4.5[/tex]

[tex]2\sqrt x = 4.5\\[/tex]

Divide both sides by 2

[tex]\sqrt x = 2.25[/tex]

Square both sides

[tex]x = 2.25^2[/tex]

[tex]x = 5.0625[/tex]

So, the value of x is between 4.84 and 5.0625

i.e.

[tex]x = (4.84,5.0625)[/tex]

The only integer between the above interval is 5.

Hence:

[tex]x = 5[/tex]

Answer:

(Shown below)

Step-by-step explanation:

The Mean, AKA the average is all of the numbers added up, then divided by how many numbers there were. For example, take this data set:

3, 5, 10, 6, 5, 5

We add up all of the numbers:

3 + 5 + 10 + 6 + 1 + 5 + 5 = 35

Now, we divide by how many numbers there were. Since there were 7 numbers, we do:

[tex]\frac{35}{7} = 5[/tex]

Therefore, 5 is our Mean.

Next up, the Median. Median is just the number in the middle of the data set, but we have to put it from least to greatest. Here it is again:

3, 5, 10, 6, 1, 5, 5

1, 3, 5, 5, 5, 6, 10

As you can see, the 5 is in the middle, so it is our Median.

Now the Mode. The Mode is number that occurs most often. Again, it's easier to put the numbers from least to greatest. The data set:

3, 5, 10, 6, 1, 5, 5

1, 3, 5, 5, 5, 6, 10

So, the 5 is the Mode because it occurs thrice, while the other numbers only occur once. Remember the Mode is what the number is, not how many times it repeats.

Lastly, the Range. The Range is just the difference of the largest number to the smallest number. This one also requires to be from least to greatest.

1, 3, 5, 5, 5, 6, 10

10 - 1 = 9

Therefore, the Range of the data set is 9. I hope this helps you!

Answer:

Step-by-step explanation:

Answer:

A (100)

Step-by-step explanation:

If 2 hours pass starting at 23:35 today, then tomorrow the time will be 1:35. The difference between 1:35 and 1:15 is 20 (minutes) Because there are 120 minutes in 2 hours (60 minutes per hour), This means we do 120 minutes minus 20 minutes. This gives us an answer is A, 100 :)

Answer:

125

Step-by-step explanation:

Given

f(x) = 5x²

g(x) = 2x + 3

Now

g(-4) = 2 * (- 4) + 3

= - 8 + 3

= - 5

Also

f(g(-4)) = f( -5)

= 5 * ( -5)²

= 5 * 25

= 125

Kevin Has 4 more tom has 2 fewer them added together is 6

Answer:

3x² -16x - 12

factored:

(3x + 2)(x - 6)

Answer:

-24

Step-by-step explanation:

According to the Question ,

⇒ f(x) = -3x + 3 .

For finding the value at x = 9 , put x = 9 ,

⇒ f(9) = -3(9) + 3

⇒ f(9) = -27+3

⇒ f(9) = -24

Answer:

f(3) = -20

Step-by-step explanation:

Replace each instance of x in 3^2x -9 =0 with 3:

f(x) = -2x2 + x-5 =  f(x) = -2x^2 + x-5 (" ^ " represents "exponentiation")

f(3) = -2(3)^2 + 3 - 5

f(3) = - 18 - 2 = -20
