The mayor of a town wants to find the probability that families with three children have all girls. Which simulation will best model the situation?
1.) a numbered cube rolled 3 times
2.) three coins flipped 10 times
3.)a spinning wheel with three colors, spun twice
4.)a random-number generator, generating numbers from 1 to 10, pressed twice

B:Three coins flipped 10 times

Step-by-step explanation:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
