Answer:

144 students

Step-by-step explanation:

12/28=3/7

3/7*336=144

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

If out of 28 students, 12 students packed their lunch.

The number of students who packed their lunch out of 336 students is 144 students.

It is the quantity of an amount of something at a rate of one of another quantity.

Example:

3 miles in 3 hours.

1 mile in one hour.

We have,

In a class of 28 students, 12 students packed their lunch.

We can write this as:

28 students = 12 students packed lunch ______(1)

We have to make 28 students into 336 students.

This can be done by multiplying 12 on both sides of the equation (1)

Multiply 12 on both sides.

12 x 28 students = 12 x 12 students packed lunch

336 students = 144 students packed lunch

Thus,

The number of students who packed their lunch out of 336 students is 144 students.

Answer:

0,40789

Step-by-step explanation:

To pick 1 red marble (from 5 red) from all 20 marbles is 5/20 = 0.25

To pick 1 green marble (from 3 green) from 19 because we already took red marble is 3/19 = 0.15789

The probability of randomly choosing a green marble after you have chosen red is 3/68.

Given

A jar has 20 marbles: 3 green, 12 blue, 5 red.

In probability theory, an event is a set of outcomes of an experiment or a subset of the sample space.

The total number of marbles = 20

The number of green marbles= 3

The number of blue marbles = 12

The number of red marbles = 5

The probability of choosing a red marble = Number of red marbles / Total number of marbles

= 5/20

The probability of choosing a green marble is =  Number of green marbles / New total number of marbles

= 3/19

Therefore,

The probability of randomly choosing a green marble after you have chosen red is;

[tex]\rm=\dfrac{5}{20}\times \dfrac{3}{19}\\\\=\dfrac{1}{4}}\times \dfrac{3}{19}\\\\ = \dfrac{3}{68}[/tex]

Hence, the probability of randomly choosing a green marble after you have chosen red is 3/68.

Symmetric property of equality to show that 3a = 4b, then 4b = 3a?

The symmetric property of equality is a simple property that says we can interchange the sides of an equation without changing the truth-value of the equation. That is, if a = b, then b = a. Each side of the equation can be thought of as the mirror image of the other

We have the following information available from the question is:

We have to determine the which property can be used to show that if 3a = 4b, then 4b = 3a

Now, According to the question:

3a = 4b

4b = 3a (both are equal)

This property is used to simplify the equations, to reverse the equations, and also for proofs in numerical and non-numerical logic.
