Finding the numeric value of the regression line, it is found that the electric bill in a month with temperature of 48 degrees is of $157.59.
How to find the numeric value of a function or of an expression?
To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.
In the context of this problem, the function is given as follows:
y = 227.19 - 1.45x.
Which y giving the electric bill for a month of temperature x degrees.
The temperature is of 48 degrees, hence to find the electric bill, the lone instance of x in the function is replaced by 48, hence:
y = 227.19 - 1.45(48) = $157.59.
Hence the electric bill in a month with temperature of 48 degrees is of $157.59.
What is the missing information?
The regression line is missing in this problem, as is defined as follows:
y = 227.19 - 1.45x.
In which:
- y is the electric bill.
- x is the monthly temperature.
The problem asks for the electric bill in a month with temperature of 48 degrees.
