A protractor is a tool used for measuring and drawing angles. It is typically a semi-circular piece of plastic or metal with a degree scale marked along its curved edge.

The scale typically ranges from 0 to 180 degrees, which covers half a circle. To measure or draw an angle of 45 degrees, you would line up the protractor's baseline with one arm of the angle and use the degree scale to find 45 degrees. If you are drawing the angle, you would then use a straightedge to extend the other arm of the angle from the point where it intersects the 45-degree mark on the protractor.

It's important to note that the 45-degree angle represents 45/360 of a full circle, which is equal to one-eighth of a full rotation. This means that if you were to rotate the angle around its vertex, it would make one-eighth of a full circle before aligning with its original position.

MJ = 3

ML = 8

Step-by-step explanation:

In this problem, we need to use the Median of a Triangle Formula. This formula states that EM/EL = FM/JF = DM/DK = 2/3. To implement this into our question, we can write ML/EL = 1/3, so we get that ML = 24/3 = 8. We also know that MJ/FM = 1/2, so MJ = 6/2 = 3. Finally, DM/DK = 2/3, so DK = (12*3)/2 = 18.

The another term for the average value of a distribution is "mean."

The mean is a commonly used measure of central tendency that represents the average value of a set of data. It is calculated by summing up all the values in a dataset and dividing by the total number of observations. The mean is a useful tool for summarizing the general tendency of a dataset and is used as a basis for other statistical calculations such as variance and standard deviation.

However, the mean is sensitive to outliers, meaning that a few extreme values in a dataset can greatly affect the mean. For this reason, it's sometimes necessary to use other measures of central tendency, such as the median or mode, to get a better understanding of the central tendency of a dataset.

The exponential function for each set of points is y = 3 * 2ˣ,

What is the exponential function?

An exponential function is a Mathematical function in form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

The exponential function can be described as y = 3 * 2ˣ,

where,

x is the input value

and y is the output value.

This function says that for every increase in x by 1 unit, the value of y will be multiplied by 2, starting from an initial value of 3.

For example, when x = 0, y = 3 * 2⁰ = 3, and when x = 1, y = 3 * 2¹ = 12.

To find the probability that the student ONLY takes History Class, we need to divide the number of students taking only History (37) by the total number of students (150).

Probability is the measure of the likelihood or chance of an event occurring. It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. Probability can be used to analyze and make predictions about a wide range of situations, including games of chance, weather patterns, financial markets, and more.

Here,

Using the given numbers, we can calculate the probabilities as follows:

To find the probability that the student ONLY takes History Class, we need to divide the number of students taking only History (37) by the total number of students (150):

P(ONLY History) = 37/150 = 0.2467 or approximately 24.67%

To find the probability that the student takes BOTH History and Biology, we need to divide the number of students taking both (25) by the total number of students (150):

P(History AND Biology) = 25/150 = 0.1667 or approximately 16.67%

To find the probability that the student does NOT take History or Biology, we need to add the number of students taking neither History nor Biology (21) to the number of students taking only Biology (17), and then divide by the total number of students:

P(Neither History nor Biology) = (21 + 17)/150 = 0.2533 or approximately 25.33%

The complement of this event (i.e., the probability of taking either History or Biology) is:

P(History or Biology) = 1 - P(Neither History nor Biology) = 1 - 0.2533 = 0.7467 or approximately 74.67%

To find the probability that the student takes Biology class, we need to add the number of students taking both History and Biology (25) to the number of students taking only Biology (17), and then divide by the total number of students:

P(Biology) = (25 + 17)/150 = 0.2133 or approximately 21.33%

He would need 54 ft² material to cover the one rectangular side of the tent with the rip and 213 ft² to recover the whole tent including the bottom. The volume of the tent is 189 ft³.

Part A

He would need 54 ft² material to cover the one rectangular side of the tent with the rip. As we have to find the area of a rectangular side of a rectangle we will use the formula Area= Length × Width

∴ Area of a Rectangle = length of the rectangle × width of the rectangle

A = 9 × 6

A = 54 ft²

Part B

David's dad would need 213 ft² material to recover the whole tent including the bottom. We know that the 2 sides of the tent are 54 ft² each. So, the total is 54 × 2 = 108 ft².

We will now find the area at the bottom of the tent

A = 7 × 9

A= 63 ft²

We will now find the area of the triangular sides

Triangle Area = 1÷2 × b×h

A = 1÷2 × 7 × 6

A =  1÷2 × 42

A = 21  ft²

As there are 2 triangular sides so we have to multiply it by 2

∴ 21 × 2 = 42 ft²

Add all the sides together 108  63 + 42 = 213 ft²

Part C

The volume of the tent is 189 ft³. It can be found by applying the formula V= b×h

Triangle area = 1÷2 × bh

A = 1÷2 ×7 × 6

A=  1÷2 × 42

A= 21

With a=21 as B and h= 9ft and applying the formula v=Bh

Distance = speed * time

12s = 8(s+20)

12s = 8s + 160

12s - 8s = 160

4s = 160

s = 160/4

s = 40 mph

If <A = 51° then the measure of angle ABE be 39°.

The term "right triangle" refers to a triangle with an interior angle of 90 degrees. The hypotenuse, the side that faces the right angle and is also the side with the longest side in a right triangle, and the height and base are the two arms of the right angle.

It is 90 degrees at a right angle. Angles smaller than 90 degrees are considered sharp angles. More over 90 degrees is considered an obtuse angle. Additionally, these angles aid in categorizing the various triangular varieties.

ΔABE = 180 degree

Let the equation be

∠A + ∠B  + ∠E = 180 degree

simplifying the above equation, we get

51° + ∠B + 90° = 180°

Step-by-step explanation:

Let's start by defining the variables for the problem. Let's say that:

w = the width of the rectangular garden (in meters)

l = the length of the rectangular garden (in meters)

We know that the length is 45 meters more than twice the width, so we can write:

l = 2w + 45

We also know that we have 1350 meters of fencing available to enclose the rectangular garden. The perimeter of the rectangular garden is equal to the sum of the lengths of all four sides. Since there are two sides of length w and two sides of length l, we can write:

Perimeter = 2w + 2l

Substituting the expression for l that we derived earlier, we get:

Perimeter = 2w + 2(2w + 45)

Perimeter = 6w + 90

We know that the perimeter of the rectangular garden is equal to 1350 meters, so we can write:

1350 = 6w + 90

Solving for w, we get:

6w = 1260

w = 210

Now that we know the value of w, we can use the expression for l that we derived earlier to find the length:

l = 2w + 45

l = 2(210) + 45

l = 465

Therefore, the dimensions of the rectangular garden should be 210 meters by 465 meters.

If you have three points in space , we can use direction vector , check if vectors are collinear or proportional to know those 3 points lie on the same line.

If you have three points in space and you find a vector that is projected onto another vector from each of these three points, it is possible to determine if the three points lie on the same line. Here's how you can do it:

Find the direction vector: Calculate the direction vector from one of the points to the other two points.

Check if the projection vectors are collinear: If the projection vectors from all three points are collinear, it means that they are all pointing in the same direction and are proportional to each other.

Check if the projection vectors are proportional: If the projection vectors are proportional, it means that they are all pointing in the same direction, and the three points are on the same line. Note that in order to determine if the projection vectors are proportional, you would need to know the magnitude of the projection vectors.

If the three points do lie on the same line, the direction vector found in step 1 will be proportional to the projection vectors found in step 2 and step 3, and all three points will lie on the same line in space.
