Barry asked 40 random students at his school to name their favorite ice cream flavor. of the 40 students he asked, 25 of them preferred chocolate. based on barry's results, how many of the 1,200 students in the school most likely prefer chocolate ice cream?

my answer is c check my work

750

Step-by-step explanation:

62.5% choose chocolate

1200 x 62.5% of is 750

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
