Answer:24+4x
Step-by-step explanation:
a=5. PHOTO
b=7. PHOTO
a1=5+x. FRAME
b1=7+x. FRAME
Pf=2*(a1+b1)
Pf=2*(5+x+7+x)
Pf=2*(12+2x)
---------Pf=24+4x. - - - - - - PERIMETER OF FRAME
<u>Answer:</u>
She paid 26.35 for something that would usually be 31 dollars. The percentage discount she got is 15%
<u>Solution:</u>
A lady paid $26.35 for something that is usually $31, so she got a discount for the product.
Now, we have been asked to find out how much percentage discount she got.
To do that we first have to check how many dollars she got off the product.
To do so we have to subtract the discounted price from the initial price.
Therefore we get:
31 - 26.35 = 4.65
To find the percentage discount we need to do the following

Therefore she got a discount of 15%
Answer:
The slope is m=0
Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.
Explanation:But since the y-coordinates of the points are equal, we can find the slope easier than just by using above formula.If y-coordinates are equal and x-coordinates are not equal (as in our case), then the slope equals 00 (the line is horizontal).
Answer:
b. no autocorrelation.
Step-by-step explanation:
The Durbin-Watson test assumes that
H0:ρ=0
HA:ρ≠0
p=0 is a statement for the null hypothesis that assumes that the error term in one period is not correlated to the error term in the previous period.
The Durbin-Watson test is used in regression analysis to test for autocorrelation. The results from the test would always range from 0 to 4. A value of less than 2.0 indicates positive autocorrelation. A value of 2.0 indicates no autocorrelation, and a value of 2.0 to 4.0 indicates negative autocorrelation.
