The answer is 329. If you set this up as a proportion you get 28/40=x/470 then you cross multiply 28x470 to get 13,160 and decide it by 40 to get 329

So from that i think the formula would be
\frac{x}{470}  =  \frac{28}{40}
so then you find "x" by multiplying 470 x 28 which equals 13,160. Then you divide 13,160 by 40 which equals 329.
X=329
329 students are likely to have phones

It should be noted that the relationship is not linear based on the information illustrated as the difference between the numbers aren't the same.

<h3>How to illustrate the information?</h3>

It should be noted that an equation is simply used to illustrate and express the relationship between the variables.

It should be noted that for the relationship to be linear, it's essential that they've the same relationship between them.

When x = 1, y = 4.5. The

When x = 2, y = 6.5

When x = 3, y = 8.5

When x = 4 y = 11.5

It should be noted that there's a difference of 2 at first but between 3 and 4, there is. a difference of 3.

Therefore, the relationship is not linear.

Suppose y varies inversely as x, and y = 16 when x = 1/2. Find y when x = 17.
MArishka [77]

<u>Finding the proportionality constant</u> :

  • y = k/x
  • 16 = k/(1/2)
  • <u>k = 8</u>

<u>Finding y when x = 17</u> :

  • y = 8/(17)
  • y = 8/17

The value of y is <u>8/17</u> when x = 17.
