Answer:
30 ft²
Step-by-step explanation:
Area of trapezium = 1/2 (a + b)h
a = 6 ft , b = 9 ft , h = 4 ft
Area = 1/2 (6 + 9) 4
= 30 ft²
Answer:
The answer is that you tutored for 4 hours.
Step-by-step explanation:
There are 6 total squares, so then you must divide 12 by the number of squares (6), to find the value of one square. Then, you would find that one square equals 2 hours, and since you have 2 squares that means that you tutored for 4 hours.

Answer:
25
Step-by-step explanation:
12 months in a year
From 31 January 2020 to 31 December 2020 = 12 months
From 31 January 2021 to 31 December 2021= 12 months
include final January = 1 month
12+12+1=25
Answer:
See explanation below.
Step-by-step explanation:
When we want to fit a linear model given by:
Where y is a vector with the observations of the dependent variable, the parameters of the model and x the vector with the observations of the independent variable.
For this case this population regression function represent the conditional mean of the variable Y with values of X constant. And since is a population regression the parameters are not known, for this reason we use the sample data to obtain the sample regression in order to estimate the parameters of interest
We can use any method in order to estimate the parameters for example least squares minimizing the difference between the fitted and the real observations for the dependenet variable. After we find the estimators for the regression model then we have a model with the estimated parameters like this one:
With
And this model represent the sample regression function, and this equation shows to use the estimated relation between the dependent and the independent variable.
