The relationship between the input values (x) and the output values (y) is :'y is one less than a quarter of x'
sattari [20]

An equation in the form of y is y = x/4 - 1

<h3>An equation in the form y = ...</h3>

The statement is given as:

'y is one less than a quarter of x'

A quarter of x means x/4

So, we have:

y = x/4 - 1

Hence, an equation in the form of y is y = x/4 - 1

<h3>Number sentences</h3>

From the question, we have:

x = -4, -2,0, 2 and 4

Substitute these values in y = x/4 - 1

-4/4 - 1 = -2

-2/4 - 1 = -1.5

-0/4 - 1 = -1

2/4 - 1 = -0.5

4/4 - 1 = 0

The above represents the number sentences

<h3>The flow diagram</h3>

This is represented as:

x                     Computation           y

-4                    -4/4 - 1                     -2

-2                    -2/4 - 1                     -1.5

-0                    -0/4 - 1                     -1

2                      2/4 - 1                     -0.5

4                      4/4 - 1                     0

<h3>The table of values</h3>

This is represented as:

x   y

-4 -2

-2 -1.5

-0 -1

2  -0.5

4  0

<h3>Ordered pairs of numbers.</h3>

This is represented as:

(-4, -2), (-2, -1.5), (0, -1), (2, 0.5) and (4, 0)

What is the mean median and mode for 50, 55,42,38,163,55,61​
Likurg_2 [28]

Answer:

Mean: 67.7 (rounded to the nearest tenth)

Median: 52.2

Mode: 55

Step-by-step explanation:

To find the the mean is to take all the numbers, all them together and divide by how many numbers there is. 50+55+42+38+163+55+61= 564 then divided by 6 is 67.7

to find the median is to put all the numbers in order, (I prefer to go increasing order) and then find the middle number. If there is no  middle number you take the two numbers around it and subtract them from one n another.

Mode is to find the most common number. Whichever number repeats itself

Hope I helped!

Plot the flowing points on the number line without measuring.​
N76 [4]

Answer:

1/4, 3/5, 8/10

Step-by-step explanation:

3/5 is greater than 1/4

(2/4 is equal to 2.5/5---that should give you a visual picture why)  

8/10 is greater than 3/5

3/5 multipled by 2 is 6/10

so, 6/10<8/10
