<h3>What is a linear regression?</h3>A linear regression models the relationship between a scalar quantity and other explanatory variables, using a linear approach.
The linear regression equation is presented as follows;
y = a + b•x
Where;
=(0+1+2+3)/4 = 1.5
=(994+946+928+880)/4 = 937
=(0+1+2+3) = 6
=(994+946+928+880) = 3748
n = 4
Using the statistics function of a graphing calculator, under Scatter plot, plot type, we have;
y = 991 - 36•x
Which gives;
b = -36
a = 991
From the given parameters, we have;
<em>x </em>= The number of years since 2003
y = The number of newly reported crime cases
Required;
The number of projected new cases in 2011
Solution;
In 2011, <em>x </em>= 2011 - 2003 = 8
Which gives;
y = 991 - 36×8 = 703
The number of newly reported crime cases in 2011 is 703

Answer:
Obtuse angle
Step by step explanation:
Find 25 on a clock then add 25 and 15, you get 40. We see 40 and 15, if we separate it from the rest of the clock, then examine it we can see that it is an obtuse angle
