Answer:

254

Step-by-step explanation:

The median of a set of data is basically the middle number of the data when placed in least to greater order.

example:

1,2,3,4,5,

in this case (the example) the median is 3 becasue it is the middle number of the 5 numbers (thier are two numbers to the left of 3 and 2 numbers to the right of 3)

Going back to the question being asked if you put that data in order you would get a sequence of

154, 205, 244, 244, 253, 254, 263, 274, 276, 389, 431

now try eliminating a number from each end side one by one (alternating) until you have one number left.

For instance remove 154 and 431, then remove 205 and 389 etc

IF DONE CORRECTLY you would have 254 as the remaining number.

Answer:

254

Step-by-step explanation:

First, put the numbers in order.

431, 154, 254, 244, 244, 276, 263, 389, 253, 274, 205

154, 205, 244, 244, 253, 254, 263, 274, 276, 389, 431

The median of a data set is the middle number.

154, 205, 244, 244, 253, 254, 263, 274, 276, 389, 431

Best of Luck!

Please help<br><br> In which table does y vary directly with x?
grigory [225]

Answer:

Table D

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

<u><em>Verify each case</em></u>

<em>Table A</em>

For x=1, y=3

Find the value of k

k=y/x -----> k=3/1=3

For x=2, y=9

Find the value of k

k=y/x -----> k=9/2=4.5

the values of k are different

therefore

The table A not represent a direct variation

<em>Table B</em>

For x=1, y=-5

Find the value of k

k=y/x -----> k=-5/1=-5

For x=2, y=5

Find the value of k

k=y/x -----> k=5/2=2.5

the values of k are different

therefore

The table B not represent a direct variation

<em>Table C</em>

For x=1, y=-18

Find the value of k

k=y/x -----> k=-18/1=-18

For x=2, y=-9

Find the value of k

k=y/x -----> k=-9/2=-4.5

the values of k are different

therefore

The table A not represent a direct variation

<em>Table D</em>

For x=1, y=4

Find the value of k

k=y/x -----> k=4/1=4

For x=2, y=8

Find the value of k

k=y/x -----> k=8/2=4

For x=3, y=12

Find the value of k

k=y/x -----> k=12/3=4

All the values of k are equal

therefore

The table D represent a direct variation or proportional relationship

The linear equation is y=4x

Write an equation that is parallel to y=-5/2x-5
NeX [460]

       A parallel equation (when graphed) will have the same slope, but a different y-intercept.

       As long as you keep y = -\frac{5}{2}x + b, you can input anything for b to solve this question.

       Given:

y = -\frac{5}{2}x - 5

       Equation of a parallel line:

y = -\frac{5}{2}x + 6, y = -\frac{5}{2}x + 1,356, y = -\frac{5}{2}x - 8, etc

     Example answer you can use:

             y = -\frac{5}{2}x - 8
