Jessica's Furniture Store buys a couch at a wholesale price of \$113.00$113.00dollar sign, 113, point, 00.
andrew-mc [135]

Answer:

$50.85

Step by step explanation:

We have been given that Jessica's Furniture Store buys a couch at a wholesale price of $113.00 and the markup rate at Jessica's Furniture Store is 45%.

We can find mark-up for the couch by finding 45% of 113.  

\text{Mark-up}=113\times \frac{45}{100}

\text{Mark-up}=113\times 0.45

\text{Mark-up}=50.85

Therefore, mark-up for the couch will be $50.85.

Can you tell how old a lion is by looking at its nose? A professor at the University of Wisconsin-Madison conducted a study of d
Ghella [55]

Answer:

The residual age of a lion whose nose is 11% black and is 1.9 years old is -0.15.

Step-by-step explanation:

In regression, the difference between the observed value of the dependent variable (<em>y</em>) and the predicted value (\hat y) is known as the residual (<em>e</em>).

e=y-\hat y

The least square regression line is used to predict the value of the response or dependent variable (<em>y</em>) from the known value of the explanatory or independent variable (<em>x</em>).

The general form of a least square regression line is:

\hat y=\alpha +\beta x

The equation of the least squares regression line to predict the relationship between age (in years) and proportion of blackness in the lion’s nose is:

\hat y=0.8790+10.6471 x

Compute the predicted value of <em>y</em> for <em>x</em> = 0.11 as follows:

\hat y=0.8790+10.6471 x

  =0.8790+(10.6471\times 0.11)\\=0.8790+1.171181\\=2.050181\\\approx 2.05

The predicted value of <em>y</em> is, \hat y=2.05.

The observed value of the age of lion whose nose is 11% black is, <em>y</em> = 1.90.

Compute the residual age of this lion as follows:

e=y-\hat y

  =1.90-2.05\\=-0.15

Thus, the residual age of a lion whose nose is 11% black and is 1.9 years old is -0.15.
