Ted researched the price of airline tickets and discovered a correlation between the price of a ticket and the number of miles traveled. after recording his data on a scatter plot, he determined the equation for the line of best fit is y = 300 + 0.45x. what does 0.45 represent in the equation?

Answer

The slope of the equation.

Explanation

The general equation of line is y = mx + c, where (x,y) is a point on the line, m is the slope and c is the y-intercept.

When the line is in the equation above, we can explain the meaning of each term.

After recording the  data plotting the line, Ted came up with the equation;

y = 300 + 0.45x.

Writing this in the form of y = mx + c we have,

y = 0.45x + 300.

m = 0.45 ⇒ This is the slope of the equation.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
