X+x+10+2(2x+10) = 180
2x + 10 + 4x+20 = 180
6x + 30 = 180
6x = 150
X = 25
Plug in 25 to find angle

The city council of Pine Bluffs is considering increasing the number of police in an effort to reduce crime. Before making a fin

Answer:

Part a

The regression equation is, $\hat y = 29.3877 - 0.9596x$

Part b

The number of crimes for a city at 20 police officers was appointed is approximately 10.

Step-by-step explanation:

15 17 255 225 289

17 7 119 289 49

17 13 221 289 169

12 21 252 144 441

25 5 125 625 25

11 19 209 121 361

27 7 189 729 49

22 6 132 484 36

146 95 502 2906 1419

Therefore,

$\hat B_1=\frac{n \sum xy - (\sum x) (\sum y)}{n (\sum x^2) - (\sum x)^2}$

$= \frac{8(1502) - (146)(95)}{8(2906)-(146)^2} \\\\= \frac{-1854}{1932} \\\\= - 0.9596$

The calculation of the intercept coefficient is as follows:

$\hat B_0= \frac{\sum y }{n} - \hat B_1 (\frac{\sum x}{n} )$

$= \frac{95}{8} - (-0.9596)(\frac{146}{8} )\\\\= 11.875 + 17.5127\\\\= 29.3877$

The regression equation is, $\hat y = 29.3877 - 0.9596x$

The calculation is as follows:

$\hat y= 29.3877 - 0.9596x\\\\= 29.3877-0.9596(20)\\\\=29.3877-19.1920\\\\=10.1957$

≅ 10

The number of crimes for a city at 20 police officers was appointed is approximately 10.

That is, the number of polices increases then the number of crimes will be decreases.
