Answer:
11. x= 117 and y =57
12. 9
13. 900 degrees
Step-by-step explanation:
11. Y can be found using supplementary angles. 123+y = 180 since they form a straight line. This means y=57. The inside of a quadrilateral is equal to 360 degrees. This means 117+69+57 +x=360. Then 243+x=360 and x= 117.
12. The exterior angles of a polygon with n sides is 360/n. Since we don't know n but we do know the angle is 40 degrees, we write 360/n=40. Solve for n.
360/n=40
360=40n
360/40=n
n= 9
13. This figure is a regular sides polygon. It has 7 sides and therefore 900 degrees.
Answer:
convert 4.5 <em>what</em> though?
This is an example to show you what it means to be closed:
If you multiply two real numbers, you will get another real number. Since this process is always true, it is said that the real numbers are "closed under the operation of multiplication.
I truly hope this helps!!

Answer:
D. For each additional room in the house, the appraised value is estimated to increase $74,800
Step-by-step explanation:
The statistical model is used to predict the appraised value of houses in East Meadows. The value of a house is determined by using variables. The regression model helps to analyse the value of a house. It is predictive modelling technique which determines a relationship between dependent and independent variable.
