16 lakh students in India use khan academy today. The number of users are expected to grow by 50% every year. How many students in India would be using Khan Academy two years from now ?

32,00,000

Step-by-step explanation:

We can use the formula

16,00,000 x 0.5 x 2 = 16,00,000

Total no. of students using Khan Academy after 2 years will be:

1600000 + 1600000 = 32,00,000

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages
