Luis wants to buy a skateboard that usually sells for $79.70. All merchandise is discounted by 12%. What is the total cost of th
stira [4]

Answer:

$64.36

Step-by-step explanation:

12% percent of %79.70 is %9.56 and there is a 12% discount so you will subtract $9.56 from %79.70 and you will get $70.14. Now we need 8.25% of %70.14 and now you have $64.36.

I hope this helps.

Suppose the line of best fit for some data points has a slope of 4.915. If the mean of the x-coordinates of the data points is 1
aleksley [76]

The y-intercept of the linear equation of best fit, considering the slope and the means, is of -60.428.

<h3>What is a linear function?</h3>

A linear function is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
  • b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.

For a line of best-fit, the y-intercept is given by:

b = \overline{y} - m\overline{x}

The parameters in this problem are given as follows:

m = 4.915, \overline{x} = 14.347, \overline{y} = 10.088

Then:

b = 10.088 - 4.915(14.347) = -60.428
