The equation of line is y = 92x – 182631. The slope is 92 and the y-intercept is the negative 182631. And the health expenditure in 2010 will be 2289.

<h3>What is the equation of a line passing through two points?</h3>

Suppose the given points are (x₁, y₁) and (x₂, y₂), then the equation of the straight line joining both two points is given by

$\rm (y - y_1) = \left [ \dfrac{y_2 - y_1}{x_2 - x_1} \right ] (x -x_1)$

In MODE, (second line), fix the number of decimal places to be 2.

Then the slope and the y-intercept values of the Lin Reg line will round to the nearest hundredth.

(x₁, y₁) → (1997, 1093)

(x₂, y₂) → (2002, 1553)

Then we have

y – 1093 = [(1553 – 1093) / (2002 – 1997)] (x – 1997)

y – 1093 = [460 / 5] (x – 1997)

y – 1093 = 92 (x – 1997)

y = 92x – 182631

If x = 2010, then the value of y will be

y = 92 × 2010 – 182631

y = 184920 – 192631

y = 2289

If A represent the number of apples purchased at 15 cents each, and B represents the number of bananas purchased at 10 cent each

DiKsa [7]

We have A number of apples, each purchased at 15 cents.
We can, thus, calculate the total cost of apples as follows:
Total cost of apples = 15A cents

We have B number of bananas, each purchased at 10 cents.
We can, thus, calculate the total cost of bananas as follows:
Total cost of bananas = 10B cents

Now, the total cost of purchases can be calculated by adding the amount paid for both types (apples and bananas) as follows:
Total cost = cost of apples + cost of bananas = 15A + 10B cents

If the original bill is $22.50, what will be the final bill after a 15% tip is paid? round to the nearest cent

Studentka2010 [4]

For this case what you should do is take 15% of 22.50 and add it to the original price. We have then:
((15) / (100)) * (22.50) = 3.375
Then, we add to the original price:
22.50 + 3.375 = 25.875
round to the nearest cent
25.88
answer
C.$25.88
