The Distributive Property allows you to say that 3(x − 1) = 3x −

Serga [27]

Answer:

$3x - 3$

Step-by-step explanation:

In the distributive property each value inside the parenthesis will be multiplied by the value outside the parenthesis.

In the expression 3(x - 1) it will look like:

$(3 . x) - (3 . 1)$

Then we multiply both value separately giving us:

$3x - 3$

So in conclusion it would be right to assume that.

$3(x - 1) = 3x - 3$

Can anyone help me with the answer for number 4

klio [65]

Answer:

Step-by-step explanation:

Given K is the midpoint of JL, then

JK = KL ← substitute values

6x = 3x + 3 ( subtract 3x from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Hence

JK = 6x = 6 × 1 = 6

KL = 3x + 3 = (3 × 1) + 3 = 3 + 3 = 6

JL = 6 + 6 = 12

A department store, on average, has daily sales of $28 comma 286.28. The standard deviation of sales is $1 comma 500. On Tu

wolverine [178]

Answer:

z-score = 4.43,

It is a Good day

Step-by-step explanation:

The provided information is:

Mean = $28,286.28

Standard deviation = $1,500

Let x be the sell of department store on Tuesday.

Then, x = $34,924.62

The z-score is define as:

$z=\dfrac{x-\mu}{\sigma}\\\\=\dfrac{34924.62-28286.28}{1500}\\\\=4.43$

Thus, the Tuesday's z-score is 4.43. So this is usually good day.
