Find the median for each set of data 4,12,7,6,10,5,11,8​

Mathematics
1 answer:
Ainat [17]2 years ago
5 0

Answer:

7.5

Step-by-step explanation:

The median is the middle data in a set. To find the median first order the set for least to greatest. In this case, 4,5,6,7,8,10,11,12. Then find the number in the middle, however, because there is an odd number of data you must take the mean of the two middle numbers. The two numbers in the middle are 7 and 8, so to find the mean of these numbers add them then divide by the number of terms, aka 2. (7+8)/2=7.5, therefore the median must be 7.5.

192 divided by 15 as a fraction of the remainder
Bogdan [553]

Answer:

Start by setting it up with the divisor 15 on the left side and the dividend 192 on the right side like this:

           

 1 5 ⟌ 1 9 2

Step 2:

The divisor (15) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:

       0    

 1 5 ⟌ 1 9 2

Step 3:

Multiply the divisor by the result in the previous step (15 x 0 = 0) and write that answer below the dividend.

       0    

 1 5 ⟌ 1 9 2

      0    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.

       0    

 1 5 ⟌ 1 9 2

     - 0    

       1    

Step 5:

Move down the 2nd digit of the dividend (9) like this:

       0    

 1 5 ⟌ 1 9 2

     - 0    

       1 9  

Step 6:

The divisor (15) goes into the bottom number (19), 1 time(s). Therefore, put 1 on top:

       0 1  

 1 5 ⟌ 1 9 2

     - 0    

       1 9  

Step 7:

Multiply the divisor by the result in the previous step (15 x 1 = 15) and write that answer at the bottom:

       0 1  

 1 5 ⟌ 1 9 2

     - 0    

       1 9  

       1 5  

Step 8:

Subtract the result in the previous step from the number written above it. (19 - 15 = 4) and write the answer at the bottom.

       0 1  

 1 5 ⟌ 1 9 2

     - 0    

       1 9  

     - 1 5  

         4  

Step 9:

Move down the last digit of the dividend (2) like this:

       0 1  

 1 5 ⟌ 1 9 2

     - 0    

       1 9  

     - 1 5  

         4 2

Step 10:

The divisor (15) goes into the bottom number (42), 2 time(s). Therefore put 2 on top:

       0 1 2

 1 5 ⟌ 1 9 2

     - 0    

       1 9  

     - 1 5  

         4 2

Step 11:

Multiply the divisor by the result in the previous step (15 x 2 = 30) and write the answer at the bottom:

    012

 15⟌192

    -0    

    19  

    -15  

    42

    30

Step 12:

Subtract the result in the previous step from the number written above it. (42 - 30 = 12) and write the answer at the bottom.

   012

 15⟌192

    -0    

    19  

    -15  

    42

    -30

    12

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 192 divided by 15 calculated using Long Division is:

12

Solve the equation 1/2x -5+2/3x=7/6x+4
prohojiy [21]
1/2x -5+2/3x =7/6x+4
First, you need to find the least <span>common </span>denominator between the 3 fractions....
2-3-6 The GCF is 6...
So to get rid of the fractions, multiply the whole equation by 2

6[ 1/2x -5+2/3x =7/6x +4 ]=
3x -30 +4x =7x +24

Now that we got rid of our fractions, we combine like terms...

3x -30 + 4x= 7x + 24
7x -30 = 7x + 24
-30 = 24 is not true

So, there is no solution

Hope this helps Nic

Figure PQRS is a parallelogram. The expressions represent the measures of the angles in degrees. Parallelogram P Q R S is shown.
ch4aika [34]

Answer:

20°

Step-by-step explanation:

the sum of the angles gives 180°

20+2x+6x=180

20+8x=180°

8x=180-20

x=160°÷8°

x=20°

thank you!
