Mr. Preston has 2 math classes. Class
one has 27 students and class two
has 26 students. If each student
answered 18 test questions, how many
questions does Mr. Preston have to
grade in all?

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

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

median- 36f

mode - none

mean- 33.7 ~ 34f
