Answer:
72 kph
Step-by-step explanation:
The first sentence tells you the speeds are proportional. So, you can write the proportion ...
kph/mph = 120/75 = x/45
Multiplying by 45 gives x:
x = (45)(120/75) = 72
72 kph is 45 mph.
Answer:
a) 
b) y = 289.815
Step-by-step explanation:
We are given the following information:
The estimate regression equation for a model involving two independent variables and 10 observations follows:

where
are the two independent variable and y is the dependent variable.
a) The regression line is of the form:

Comparing, we get,

These are the coefficients of
respectively, and helps us to know the the significance of the independent variable in predicting the independent variable.
b) We have to estimate y when

46482 is the correct answer
