In a recent poll 60% of the middle school preferred pizza for lunch on Friday 27% prefer tacos and 13% preferred hotdogs the middle school have 860 students for Friday lunches how many prefer pizza

516 students preferred pizza

Step-by-step explanation:

To solve this problem we have to calculate 60% of the total students (860)

To get the percentage of a number we have to divide by 100 and then multiply by the number it indicates, in this case 60

860 %60 = 860 / 100 * 60

860 / 100 * 60 =

8.6 * 60 = 516

60% of 860 is 516

this means that for Friday lunches 516 students preferred pizza

ou would have 12 of each

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
