In MODE, (second line), fix the number of decimal places to be 2. Then the slope and the y-intercept values of the LinReg line w
olasank [31]

The equation of line is y = 92x - 182631. The slope is 92 and the y-intercept is - 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

The school is planning to add 2 new playgrounds. Each playground will be in the shape of a square that measures 10m by 10 m. Wha
mojhsa [17]

Answer:

Each playground will be 100 m2. Both playgrounds are 200 m2.

Step-by-step explanation:

Area of square is defined by a × a.  

a = length of side. In this case a is 10 m

So,  Area = 10 m × 10m

Area = 100 m2 (square meters). This is the area of one playground.

Two playgrounds will be the double, 200 m2
