After counting all the intermediate school students, the principal came to the conclusion that 4 out of every 7 students was a boy. If there are 651 students in the building, how many of those students are boys? Hint: Find an equivalent ratio/proportion!

372

Step-by-step explanation:

4 out of 7 is 4/7. So just multiply 651 by 4/7

651 x 4 is 2604

2604 divided by 7 is 372.

If you turn 4/7 into a decimal, It is about 57%

And 57% of 651 is about 372 so it is checked.

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
