28 students travel on a field trip. They bring a van that can seat 12 students. Elena and Kiran's teacher asks parents to drive cars that seat 3 children each to transport the rest of the students. Elena wonders if she should use the inequality
12+3>28
12
+
3
n
>
28
or
12+3≥28
12
+
3
n

28
to figure out how many cars are needed. Kiran doesn't think it matters in this case. Solve the inequality to explain why Kiran is correct. (use / to represent fractional quantities and a space between whole numbers and the fraction. Example
112

type as 1 1/2)

n

Yes, you can use this inequality to find the numbers of cars required.

Step-by-step explanation:

12  + 3n > 28     where n = the number of cars required

3n > 28 -12

3n > 16

n > 5 1/3

Greater than 5 1/3 gives 6 cars.

See below.

Step-by-step explanation:

12 + 3n ≥ 28

3n ≥ 16

n ≥ 5 1/3

The number of cars must be equal to or greater than 5 1/3.

Since there is no 1/3 of car, that means there must be 6 cars.

Whether the inequality is 12 + 3n > 28 with a solution of more than 5 1/5 or the inequality is 12 + 3n ≥ 28 with a solution of 5 1/3 or more, the answer is the same because the minimum number of cars that will be enough is 6.

7

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
