VERY IMPORTANT QUESTION PLEASE SOLVE IT;(:(:(

1)20

2)55

3)35

4)math=15, English=20

5)shown above

Step-by-step explanation:

1) add 15 students who like math only and 20 liked English only and 5 who did not like any subjects

15+20+5=40

subtract by total class of 60 students

60-40=20 students to like both subjects

2) add 15 students who like math only, 20 students who like English only and 20 students who like both subjects

15+20+20=55 students to like at least one subject

3) add 15 students who like math only and 20 students who like English only

15+20=35 students to like only one subject

4) as shown in Venn diagram

math=15 students, English=20 students

the above table 1 will calculate the population size (n) after a certain length of time (t). all you need to do is plug in the initial population number (no), the growth rate (r) and the length of time (t). the constant (e) is already entered into the equation. it stands for the base of the natural logarithms (approximately 2.71828). growth rate (r) and time (t) must be expressed in the same unit of time, such as years, days, hours or minutes. for humans, population growth rate is based on one year. if a population of people grew from 1000 to 1040 in one year, then the percent increase or annual growth rate is 40/1000 x 100 = 4 percent.
