To solve this problem you must apply the proccedure shown below:
1- You have that the area of the living room is:
A=lw (Area of the rectangle); where l is the lengt and w is the width.
A=(21 feet)(15 feet)
A=315 feet²
2- The cost is:
Cost=315 feet²x$9
Cost=$2835
The answer is: He will need 315 feet² and it will cost $2835
Answer:
The correct answer is the value has no practical interpretation since a GMAT of 0 is nonsensical and outside the range of the sample data.
Step-by-step explanation:
Solution
Given that:
We define Define Y : dependent variable ( Starting salary of a graduate at a top business school )
Thus,
X : independent variable ( GMAT score )
So,
The Required linear regression equation is stated below:
y = 228 x - 92,040
Here,
The y intercept is = - 92040
The Interpretation of the y - intercept is defined as:
The value has no practical interpretation since a GMAT of 0 is nonsensical and outside the range of the sample data .

Answer How many liters of a 20% acid solution should be mixed with 30 liters of 50% acid solution in order to obtain a 40% solution. ... x=15 liters 15*(.20 pure acid)=3 liters 30*(.50 pure acid)=15 liters That is 18 liters pure acid That is 45 liters solution *0.45 pure acid=18 liters.
As more pure acid is added, the concentration of acid approaches 0.
