Answer:

Your answer depends on the numbers showed to you.

Step-by-step explanation: To find your answer you need to look at the numbers on the x-axis are they the same repeating number each time(-1,9),(2,3),(4,-3)(-1,7) if they look like the example I just gave you then it is not a function. If the x-axis has all different number then yes it is a function.

The scenario 1 is not a function, while the scenario 2 is a function

Scenario 1:

The relationship is between:

It is true that a certain shoe size can belong to students of different heights.

This means that the relation is a one-to-many relation

A one-to-many relation is not a function;

Hence, this is not a function

Scenario 2:

The relationship is between:

It is true that a student can have only one height.

This means that the relation is a one-to-one relation

A one-to-one relation is a function;

Hence, this is a function

Answer: 12.7

Step-by-step explanation:

r=d/2

3.5/2=r

The expression which is equivalent to -3(b - 7) is -3b + 21. Hence, option B is correct.

Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.

Answer:

29.3 minutes

Step-by-step explanation:

The average, also the mean, is all the numbers added together and then divided by the amount of numbers there, here, all the numbers added together are 20 + 30 + 40 + 38 + 25 + 22 + 39 + 22 + 26 + 31 = 293

There are a total of 10 numbers here, so 293/10 = 29.3

Answer:

Step-by-step explanation:

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

The probability of choosing a green shirt is 20%=1/5=.2

Step-by-step explanation:

find the total amount = 10

Find the total of question (probability of choosing green) = 2

set as a fraction:

Numerator = amount needed (2)

Denominator = all things/objects involved (10)

PS*

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction

ex:

10/2=5=500% (this can't be the answer)

So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

Answer: 4 miles are equal to 7040

Step-by-step explanation:

As we know that the ratio can be simplified and the answer can be obtained,

according to the question 5 miles are equal to 8800.

so, here we arrange the ratio in its format as follows

Step 1:

              Miles: Yards

                      5:  8800

Step 2: here we bring the ratio to its simplest form by dividing by 5 on both sides, that is:

5/5=1

8800/5= 1760

Now we get:

                         Miles: Yards

                                 1: 1760

Step 3: now as we need to find the answer for 4 miles we need to multiply with 4 on both sides, that is:

                         Miles: Yards

                                4: 7040

from here we get the answer as 4 milesequalso 7040 yards.

Answer:

Step-by-step explanation:

x + y = 12 ---------------(1)

3x - 5y = 4 --------------(2)

(1)*5 + (2) * 1 then,

5x + 3x = 60 + 4

8x = 64

x = 64/8

x = 8

from (1), 8 + y = 12

y = 4

apply(x,y)=(8,4) to these function.

-2x-4y = -32 no

-2x+6y=8 yes

like this

The required expression after the addition of the equations is  4x  - 4y = 16, and the expression after the subtracting of the equations is -2x +6y =  8.

Given that,
To select all equations that can result from adding these two equations or subtracting one from the other.

equation 1: x + y = 12
equation 2: 3x - 5y = 4

The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.

Here,
Addition
  x  +   y  = 12
+ 3x - 5y =  4
--------------------
 4x  - 4y  = 16

Subtraction,
  x  +  y  = 12
- (3x - 5y =  4)
--------------------
  x  +  y  = 12
- 3x + 5y = -4
---------------------
-2x + 6y = 8

Thus, the required expression after the addition of the equations is  4x  - 4y = 16, and the expression after the subtracting of the equations is -2x +6y =  8.

Answer:

B. 82

Step-by-step explanation:

The easiest way to find a median on a stem-and-leaf plot, is to simply count the number of "leaves" and find the middle. There is 21 numbers in the leaf column, so the 11th one is the middle. Or you could count from both sides until you reach the middle. The median of the leaves is the 2 in the middle row. This matches with the stem of 8, making the actual number 82.
