Find the median of the following data:
19, 21, 18, 17, 18, 22, 46
Median
Your answer

Answer:

80%

Step-by-step explanation:

1. We assume, that the number 56 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 56, so we can write it down as 100%=56.

4. We know, that x% equals 44.8 of the output value, so we can write it down as x%=44.8.

5. Now we have two simple equations:

1) 100%=56

2) x%=44.8

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=56/44.8

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 44.8 is what percent of 56

100%/x%=56/44.8

(100/x)*x=(56/44.8)*x       - we multiply both sides of the equation by x

100=1.25*x       - we divide both sides of the equation by (1.25) to get x

100/1.25=x

80=x

x=80

now we have:

44.8 is 80% of 56

Answer:

Hi there!!

Your answer is:

44.8 is 80% of 56!

Step-by-step explanation:

56 = 100%

/56

1 = 1 &11/14

×44.8

44.8 = 80%

Answer:

It is 129

Step-by-step explanation:

Since all the digits in the decimal from right to left are less than 5, they all are nearest to 0

So 129.444 can be rounded to 129.000 or 129

Answer:

36

Step-by-step explanation:

So u do 20 multiply 2=40-4=36

to check the answer we know that it has to be out of 100% so u can do 20+36+40+4=100 so she got 36/100% which is an F and she got 16 as her finale score I hope this works

Answer:A

Step-by-step explanation:

The graph of the given function  y = (x – 1)4 – 3 is attached below.

Suppose the considered function whose graph is to be made is; f(x)

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values; f(x) are plotted on the vertical axis.

They are together plotted on the point

(x,y) = (x, f(x))

This is why we usually write the functions as:

y = f(x)

The given function is  y = (x – 1)4 – 3

Answer:

Mean of this data set is 43.7857

the median of this data set is 42

Step-by-step explanation:

The complete question is:

Fifteen seventh graders were randomly selected to see how many pushups in a row they could do. Their data are shown. A. b. 45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36

a. Determine the mean of this data set.

b. Determine the median of this data set.

Given:

Data:

45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36

To find:

a) Mean

b) Median

Solution:

a)

The formula to find Mean is :

Mean = Sum of all the values / Total number of values

          = ∑ x / n

Here there are total 14 values so n = 14

Now lets find sum of all the values

∑ x =  45 + 40 + 36 + 38 + 42 + 48 + 40 + 40 + 70 + 45 + 42 + 43 + 48 + 36

     = 613

Now compute Mean:

Mean = ∑ x / n

          =  613 / 14

         = 43.785714

Mean = 43.7857

b)

The formula to find Median is:

Since there are 14 values in the data this means the data has even number of values. So to compute the median of even number of values:

First put the values in order.

Second, find the middle pair of values in data

Third, find the value that is half way between them i.e. by adding the two middle pair values and dividing the result by 2

45, 40, 36, 38, 42, 48, 40, 40, 70, 45, 42, 43, 48, 36

Ordering the values :

36, 36, 38, 40, 40, 40, 42, 42, 43, 45, 45, 48, 48, 70

Find the middle two numbers:

42, 42

We can see that both are same values so median value is 42 but to follow the above steps:

Now add these two numbers and divide the sum by 2:

42 + 42 = 84

84/2 = 42

So the median of this data set is 42

The difference between the given decimal numbers is 56.06.

The given decimal numbers are 58.84 and 2.78​.

We need to find the difference between the given decimal numbers.

To subtract decimals, begin by writing the numbers in a column, with the decimal points aligned. If necessary, add zeroes as placeholders to make sure there are values in each column. Subtract from right to left. Write the decimal point in the difference directly below the decimal point in the subtrahend.

Now, 58.84 - 2.78​=56.06

Therefore, the difference between the given decimal numbers is 56.06.

Answer:

q= -4

Step-by-step explanation:

[tex]5q + 6 = 2 q- 2 + q[/tex]

Collect like terms and simplify

[tex]5q - 2q - q = - 2 - 6 \\ 2q = - 8[/tex]

Divide both sides of the equation by 2

[tex] \frac{2q}{2} = \frac{ - 8}{2} \\ [/tex]

Simplify

[tex]q = - 4[/tex]

The requried solution to the equation 5q + 6 = 2q - 2 + q is q = -4.

To solve the equation 5q + 6 = 2q - 2 + q, we need to simplify and combine like terms. Let's proceed step by step:

First, let's combine the q terms on the right side of the equation:

5q + 6 = 2q - 2 + q

Combining the q terms on the right side, we have:

5q + 6 = 3q - 2

Next, let's isolate the q term by moving all other terms to the opposite side:

To move the 3q term to the left side, we subtract 3q from both sides:

5q - 3q + 6 = -2

Simplifying the left side:

2q + 6 = -2

Next, let's isolate the constant term by moving 6 to the right side:

Subtracting 6 from both sides:

2q = -2 - 6

2q = -8

Finally, to solve for q, divide both sides by 2:

q = -8/2

q = -4

Therefore, the solution to the equation 5q + 6 = 2q - 2 + q is q = -4.

Answer: 3

Step-by-step explanation:

Let the smaller number be y.

Since the difference of two numbers is 5,then the larger number will be: y+5

The sum of three times the larger number and twice the smaller number is 30. This can be written as:

3(y+5) + 2y = 30

3y + 15 + 2y = 30

5y + 15 = 30

5y = 30 - 15

5y = 15

y = 15/5

y = 3
