Kalvin tosses a paper cup once a day for a year to determine his breakfast cereal. 85% of the time the cup will land on its side, and 15% of the time the cup will land on its end.

How many times do you expect the cup to land on its side?

How many times do you expect the cup to land on its end?
please explain your work

the cup will land on its side 310 times and it'll land on the end 55 times

Step-by-step explanation:

To determine the amount of times it lands on the side, take the days in a year, 365, and multiply that by .85, which gets you 310. To get the amount of times it lands on its end, just subtract 310 from 365.

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
