Uhh what??
Step-by-step explanation:
Do you mean like 1.75 in a decimal form??
Your answer would be 122,400.
<em>To solve, follow these steps!! </em>First let's start with the price of the motorhome, 180,000. If it <em>depreciates, </em>that means it's going to lose value ever year.
It will depreciate 4% every year, so we need to find 4% of 180,000. You can just plug this into a calculator and get 7,200.
Next, it will depreciate for 8 years, so we multiply 7,200 x 8 and get 57,600. Lastly, we will subtract this from 180,000 and get 122,400.
Answer:
Y = 0.4925X - 22.26 ;
(-12.413, 13.398) ;
Yes, there is
Step-by-step explanation:
X = IQ Score ; Y = musical aptitude
The regression equation from the table given using the slope and intercept coefficient :
Y = 0.4925X - 22.26
0.4925 = slope ; Intercept = - 22.26
The 95% confidence interval of the slope :
Confidence interval = b ± Tcritical*SE
Tcritical at 95%, df = n - 2 = (20 - 2) = 18
Tcritical = 2.1009
b = slope Coefficient = 0.4925
S.E = 6.143
Hence, we have :
Confidence interval = 0.4925 ± (2.1009 * 6.143)
Confidence interval = 0.4925 ± 12.9058287
Lower boundary = 0.4925 - 12.9058287 = - 12.413
Upper boundary = 0.4925 + 12.9058287 = 13.398
(-12.413, 13.398)
There is a significant relationship between IQ score and musical aptitude because, 0 is within the confidence interval obtained.
