A random sample of 20 students from both the Science and Math club were surveyed about what supplies they would like to purchase for various projects. If there are 240 students in the Math club, how many students can you expect to choose calculators?

84 students

Step-by-step explanation:

See the attached table

As shown there are 20 students from Math club, 7 of them would like to choose calculators.

so, the probability of students who choose calculators = 7/20

If there are 240 students in the Math club

So, the number of students expected to choose calculators = 240 * 7/20

So, the number of students = 84 students

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.
