Answer:

$42

Step-by-step explanation:

Every week, the price of jeans reduced by $6.

The total value of price reduction over the 7-week period can be calculated as the product of price reduction per week and the number of weeks. Thus,

Total price reduction = price reduction per week x number of weeks

= $6 x 7

=$ 42

How is a greater number a factor of a smaller number?

Eduardwww [97]

Explanation:

It depends on the definition of "factor" that you use.

One dictionary defines "factor" to be ...

"a number or quantity that when multiplied with another produces a given number or expression"

In that sense, 7 can be a factor of 3, because 7 × (3/7) = 3.

___

Often we use the term "factor" when we mean "integer divisor", or "positive integer divisor". Using this last definition, the only factors of 3 are 1 and 3.

Other times, we use the term "factor" to mean "prime factor." By this definition, the only factor of 3 is 3 itself.

The triplets, nick, Brian, and dan, exit their preschool classroom every day in a random order. Create an organized list to show

AfilCa [17]

The set of all possibilities is called sample space and is denoted by S.

So, S = {NBD, NDB, BDN, BND, DBN, DNB} and n(S) = 8

and we need to find the probability of NBD

E = {NBD} and n(E) = 1

The probability of an even is defined by p(E) = $\frac{n(E)}{n(S)}$

Hence, p(E) = $\frac{1}{8}$

Exercise 2.4.2: Proving statements about rational numbers with direct proofs. About Prove each of the following statements using

IgorLugansk [536]

Answer:

See Explanation

Step-by-step explanation:

(a) Proof: Product of two rational numbers

Using direct proofs.

Let the two rational numbers be A and B.

Such that:

$A = \frac{1}{2}$

$B = \frac{2}{3}$

The product:

$A * B = \frac{1}{2} * \frac{2}{3}$

$A * B = \frac{1}{1} * \frac{1}{3}$

$A * B = 1 * \frac{1}{3}$

$A * B = \frac{1}{3}$

Proved, because 1/3 is rational

(b) Proof: Quotient of a rational number and a non-zero rational number

Using direct proofs.

Let the two rational numbers be A and B.

Such that:

$A = \frac{1}{2}$

$B = \frac{2}{3}$

The quotient:

$A / B = \frac{1}{2} / \frac{2}{3}$

Express as product

$A / B = \frac{1}{2} / \frac{3}{2}$

$A / B = \frac{1*3}{2*2}$

$A / B = \frac{3}{4}$

Proved, because 3/4 is rational

(c) x + y is rational (missing from the question)

Using direct proofs.

Let x and y be

Such that:

$x = \frac{1}{2}$

$y = \frac{2}{3}$

The sum:

$x + y = \frac{1}{2} + \frac{2}{3}$

Take LCM

$x + y = \frac{3+4}{6}$

$x + y = \frac{7}{6}$

Proved, because 7/6 is rational

<em>The above proof works for all values of A, B, x and y; as long as they are rational values</em>
