By AAS congruency the two triangles are congruent
Purchase price of the house = $360,000
Price of the house after 1 year = $253,800
Percent decrease in the value of the house =
* 100
⇒ Percent decrease in the value of the house =
* 100
⇒ Percent decrease in the value of the house =
* 100
⇒ Percent decrease in the value of the house = 29.5%
Hence, the price of the house decreased by 29.5% over an year.
Answer:
x= -2 , y= 6 is the answer
Answer:
Step-by-step explanation:
95% prediction interval for the dependent variable when the independent variable value is 20,
assuming the fitted regression line is: Y = 1.50 + 6.0(X).
Assume the sample size is 20
Y = 1.50 + 6.0(X)
sample X = 20
here predicted value = 1.5+6*20
= 121.5
therefore 95% prediction interval for the dependent variable
the standard error of the regression (SEE) is 1.2.
