Answer:
Slope of this line = 0.993
Explanation:
Data provided in the question:
The regression line highway mpg =7.903 + (0.993×city mpg)
for predicting highway mileage from city mileage
Now,
The general equation for the regression line is given as :
y = mx + c
here,
y is the dependent
m is the slope of the regression line
x is the variable
c is the constant
on comparing the general regression line with the given data in the question
we get
y = highway mpg
m = 0.993
x = city mileage
c = 7.903
hence,
Slope of this line = 0.993
Answer:
418.6 J
Explanation:
We know the specific heat for water is 4.186 kJ/kg * °C, so this can also write as 4.186 J/g * °C, so the heat increases 5 C in this question, so you can get 4.186(J/g * C) * 5C * 20g = 418.6 J
