Answer:

Below.

Step-by-step explanation:

The problem would look like this:

12 3/8 / 5 1/2

My math teacher told us to write it like a normal division problem.

12 3/8 ÷ 5 1/2

One way to solve is to turn both fractions into improper fractions, so..

12 3/8

So multiply 8 x 12 = 96 + 3 = 99/8

Then, 5 1/2, 2 x 5 = 10 + 1 = 11/2

99/8 ÷ 11/2, 99 ÷ 11 = 9, 8 ÷ 2 = 4,

So your answer would be 9/4, which is an improper fraction. To simply, just divide 9 by 4, and you would get 2 1/4 (mixed number).

Answer:9/4

Step-by-step explanation:

99/8*2/11=9/4*1/1=9/4

You can cancel out 99 and 11 to 9 and 1 as they are multiples of eac hother and you can do the same for 8 and 2 to 4 and 1

exercise alone. Two methods of collecting data have been proposed. Method I: Recruit volunteers who are willing to participate.

aniked [119]

Answer:

I) If method I is used, population of generalization will include all those people who may have varying exercising habits or routines. They may or may not have a regular excersing habit. In his case sample is taken from a more diverse population

II) Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.

Match the inequality to the graph of its solution. a. n/4 ≤ -1 b. -10 ≥ -100 c. 5x ≥ 20

postnew [5]

a. n/4 ≤ -1

Multiply both sides by 4 => n ≤ - 4, which is all the real numbers less or equal than - 4.

That in the real number line is all the numbers to the left of - 4 (including -4)

The matching graph is the B.

b. -10n ≥ -100

Divide both sides by - 10 => n ≤ 10

That is all the real numbers less or equal than 10.

In the real number line it is all the numbers to the left of 10, including 10.

So, the matching graph is the A.

c. 5x ≥ 20

Divide both sides by 5 => x ≥ 4

That is all the real numbers greater or equal to 4.

In the real number line it is all the numbers to the right of 4, including 4.

The matching graph is C.
