Answer:

B 3 and C 5

Step-by-step explanation:

Answer: 13^2=169, 27^2 = 729, sqrt25 = 5, and sqrt289 = 17

Step-by-step explanation:

^2 means multiply by itself 2 times

13^2 = 13 x 13 = 169

27^2 = 27 x 27 = 729

Square root asks the question “what number multiplied by itself twice is equal to ____?”

sqrt25 = sqrt(5x5) = 5

sqrt289 = sqrt(17 x 17) = 17

=======================================================

Explanation:

Multiply each visit count with their corresponding frequency.

Examples:

and so on...

I recommend making a third column like this

\(\begin{array}{|c|c|c|} \cline{1-3}\text{Visits} & \text{Frequency} & \text{Visits*Frequency}\\\cline{1-3}0 & 12 & 0\\\cline{1-3}1 & 366 & 366\\\cline{1-3}2 & 53 & 106\\\cline{1-3}3 & 52 & 156\\\cline{1-3}4 & 155 & 620\\\cline{1-3}5 & 243 & 1215\\\cline{1-3}\end{array}\)

That way you can keep track of all the results in an organized way.

Then add everything in the third column

0+366+106+156+620+1215 = 2463

Divide this sum over the total frequency (12+366+53+52+155+243 = 881) and we'll get the mean

2463/881 = 2.7956867

Rounding to one decimal place gets us to 2.8 as the final answer.

-------------

The much longer way to do this is to imagine 12 copies of "0", 366 copies of "1", 53 copies of "2", and so on. We'll have an extremely large data set of 881 items inside it. As you can see, this second method is definitely not recommended to actually carry out. Rather it's helpful to have this as a thought experiment to see why we revert to multiplication instead.

Eg: Imagine adding 155 copies of "4". A shortcut is to simply say 4*155 = 620

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Step-by-step explanation:

Distribute the negative sign to each term inside the parenthesis.

- (9k-5p+7e-2)

To distribute the negative sign to each term inside the parenthesis:

a negative and positive = -

a positive and positive = +

a negative and negative = +

- (9k-5p+7e-2)

- 9k + 5p - 7e + 2

Step-by-step explanation:

Answer: 17

Step-by-step explanation: Take 25 and multiply it by 0.68 (25 x 0.68) and you get 17.

Answer:

A: 217.375 ft^2

Step-by-step explanation:

Lengths: a: 23.5   b: 9.25    

Perimeter: u: 65.5    

diagonal : d: 25.255    

Area: A: 217.375

Calculate area A: Use the formula A=a*b

A=a*b  

Insertion into A=1*a*b gives

A=1*23.5*9.25

A=217.375

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Answer:

The correct statement is A Its velocity was 7.8 km/s northward.

In fact, the problem says that the meteor was moving at 468 km per minute. We can convert this value into km/s, keeping in mind that there are 60 seconds in one minute: 1 min=60 s:

Answer:  9/1 .  or 9

Step-by-step explanation:

Conversion a mixed number 3 3/4 to a improper fraction: 3 3/4 = 3 3/4= 3 · 4 +3/4= 12 + 3/4 = 15/4

part 2

Conversion a mixed number 2 2/5to a improper fraction: 2 2/5 = 2 2/5= 2 · 5 +2/5= 10 + 2/5 = 12/5

part3

Multiple: 15/4 * 12/5 = 15 · 12/4 · 5 = 180/20= 9 · 20/1 · 20= 9

next intermediate step, , cancel by a common factor of 20 gives 9/1

141.37 square inches

Answer:

  about 141.4 square inches

Step-by-step explanation:

You want the area of icing on a cake that is 10 inches in diameter and 2 inches high.

The icing on a cake covers the lateral surface area and the area of the circular top. In terms of diameter, the sum of those areas is ...

  icing area = πdh +(π/4)d² = πd(h +d/4)

  icing area = π(10 in)(2 in + (10 in)/4) = π(10 in)(4.5 in)

  icing area = 45π in² ≈ 141.4 in²

The area of icing on the cake is about 141.4 square inches.

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
