Will give northlake high school has two lunch periods.

A greater percentage of second-lunch students (39%) eat outside.

Step-by-step explanation:

The proportion of students who eat first lunch is 0.54.  Out of those, 0.19 of them eat outside; this is 0.19/0.54 ≈ 0.35.

The proportion of students who eat second lunch is 0.46.  Out of those, 0.18 of them eat outside; this is 0.18/0.46 ≈ 0.39.

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
