The mean of four positive integers is 5 . The median of the four integers is 6 . What is the mean of the largest and smallest of the integers? Multiple choice: 3, 4, 5, 6 and 8

4.

Step-by-step explanation:

The sum of all the integers =  4 * 5 = 20.

The median is 6 so that means that the mean of the 2 middle numbers is 6.

So the sum of the largest and smallest numbers is 20 - 12 = 8.

Therefore the mean of these 2 numbers is 4.

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
