Answer:
Step-by-step explanation:
x^2 and -x^2 would cancel
and then it would be -7 = 1
it would be no solution
but I don't know, someone can prove me wrong I may have a lapse in my algebra at the moment
Answer:
29° + (x - 5)° = 180°
29 + x - 5 = 180
29 - 5 + x = 180
24 + x = 180
24 - 24 + x = 180 - 24
x = 156
Step-by-step explanation:
A straight line is 180°.
Set all angles (29° and (x - 5)°) equal to 180°.
Then solve for x.
Okay. I'm sure you are familiar with the DST triangle, yes? It will help you solve this problem. Distance/speed = time. 382/64 = 5.96875. Round to the nearest hundredth to get 5.97 hours.
Answer:
A, B, C, D
Step-by-step explanation:
(A) Checking the Equal Variance Assumption, the appropriate technique to use is:
- The ANOVA (Analysis of Variance) F test
- Plot residuals against fitted values
(B) Checking the Normal Assumption, the appropriate techniques to use are:
- Test for Kurtosis & Skewness
- Kolmogorov-Smirnov Test
- Q-Q Plots (the graphical method) also known as Quantile Plot
- Do not use a histogram; it is not advisable
(C) Checking for Model Misspecification, the appropriate techniques to use are:
- The Ramsey Regression Specification Error Test; also called RESET
- The Davidson & MacKinnon J. Test
(D) Checking for dependent errors, the appropriate technique to use is:
- Plot residuals against time variables
