In a class of 50 students 15 are girls. five girls and 2/7 of the boys were chosen to play a match .the total number of students chosen to play a match is.

15 students

Step-by-step explanation:

No. of boys students = No. of all students - No. of girls

no. of boys =50-15 = 35 boys

the boys that will play the match are 2/7 of boys = (2/7)x35 = 10 boys

and the girls that will play the match are 5 girls

so, no of students chosen to play = 5+10=15 students

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
