Answer:

15%

Step-by-step explanation:

Let c represent the regular price of the carpet.

Then:

sale price = regular price less discount

$374 = c - $66

Adding $66 to both sides isolates (solves for) c:

$374 + $66 = c = $440. This is the regular price.

$66

---------- = 0.15 This is the fraction of the regular price by

$440 which the regular price is reduced.

Then the percentage of this discount was 0.15(100%) = 15%

Solve for x. Enter your answer in the box. x =____°

Vlad1618 [11]

we know that

The sum of all interior angles in the polygon is equal to the formula

$(n-2)*180\°$

where

n is the number of sides of the polygon

In this problem we have

$n=6$

substitute the value in the formula

$(6-2)*180\°=720\°$

Find the value of x

$720\°=x\°+108\°+113\°+132\°+75\°+160\°\\720\°=x\°+588\°\\x\°=720\°-588\°\\x=132\°$

therefore

the answer is

the measure of x is $132\°$

Is the expression 2f + 4f + 2 – 3 equivalent to 6f – 1?

Effectus [21]

6f-1 and 2f+ 4f +2-3 are equal. 2f +4f+2-3 is 17 at f=3 because

(2•3)+(4•3)+(2-3) =

(6+12)+(-1) =

(18)+(-1)=

17
Plug in what f equals for f in the equation and evaluate
I hope this helps.

If the Durbin-Watson statistic is greater than (4 − dL), then we conclude that

solmaris [256]

Answer:

Option(b) is the correct answer to the given question

Step-by-step explanation:

1) If $d\leq dl$ then , there must be a positive Autocorrelation

According to it if the ratio d of durbin-watson is equal to or less than dL then it is called as Positive Autocorrelation.

2 ) if , then it is Inconclusive

According to it If the coefficient d of the Durbin-Watson is between dL & du then it is called as Inconclusive.

3) if $d\geq du$ then there is No proof of the Autocorrelation

According to it if the d of the durbin-watson will be less than or equivalent to du then it is called as No Autocorrelation.

4) If $d \leq (4-du)$ ) then there is No proof of the Autocorrelation

According to it if the d of the durbin-watson will be less than or equivalent to 4- du then it is called as No Autocorrelation.

5) If the $( 4 - du ) \leq d \leq ( 4 -dl )$ , then it is Inconclusive

According to it if the d of the durbin-watson is between the $(4-du) \ and \ (4-dl)$ then it is called as Inconclusive.

6) If the $d \geq (4-dl)$ then it called as negative Autocorrelation

According to it if the d of the durbin-watson is greater then $4-dl$ then it is called as negative autocorrelation.

From the point 6 we can say that the option(B) is correct
All the others options are not correct for (4 − dL), so these are incorrect option .
