Step-by-step explanation:
is going to output a number in between
and
.
Luckily you are looking for in the 1st quadrant which is contained in the given interval above, so the answer just comes down to what the calculator returns from entering
in your calculator.
You may also use the unit circle. sine value refers to the y-coordinate on there.
So you are looking for when the y-coordinate is 1/2 in the fist quadrant which is at 30 degrees.
Answer:
The break-even sales amounts is 36 or 224.
Step-by-step explanation:
Consider the provided function.
Where x is the number of televisions sold (in hundreds) and P is the profit.
We need to calculate the break-even sales amounts.
the break-even sales amounts is the sales amounts that result in no profit or loss.
That means substitute P=0 and solve for x.
Substitute a=4, b=-13 and c=4 in above formula.
Therefore, the break-even sales amounts is 36 or 224.
Answer:
a.
b. The symbol y-bar represents the average price of hotels in the area
Step-by-step explanation:
a. The regression line equation is given by:
Where Alpha represents the slope, Beta represents the intercept with the Y axis, and epsilon represents the random component of the model. Thus,
y
Obtaining:
.
b. In a simple linear regression model the value of y-bar represents the average of all values of y observed. Thus, since y represents the prices of the hotels, then y-bar is the average price of hotels in the area.
