Answer:
1, (c) 2,(c) 3,(a)
Step-by-step explanation:
1, f (x) = 2-x and f(2) = 2-2
for example f(-4) = 2-(-2) = 0
=4
3, 120° - 60° = 60
Complete question is;
Regarding the violation of multicollinearity, which of the following description is wrong?
a. It changes the intercept of the regression line.
b. It changes the sign of the slope.
c. It changes the slope of the regression line.
d. It changes the value of F-tests.
e. It changes the value of T-tests
Answer:
a. It changes the intercept of the regression line
Step-by-step explanation:
Multicollinearity is a term used in multiple regression analysis to show a high correlation between independent variables of a study.
Since it deals with independent variables correlation, it means it must be found before getting the regression equation.
Now, looking at the options, the one that doesn't relate with multicollinearity is option A because the intercept of the regression line is the value of y that is predicted when x is 0. Meanwhile, multicollinearity from definition above does in no way change the intercept of the regression line because it doesn't predict the y-value when x is zero.
Answer:
Self selection sampling.
Step-by-step explanation:
A poll that does not attempt to generate a random sample, but instead invites people to volunteer to participate is called - self selection sampling.
Self-selection sampling is a sampling method where researchers allow the people or individuals, to choose to take part in research on their own accord.
9) We have: 23,15% × 35 = 8,1025 kg
There are 8,1025 kilograms of cashew nuts were there in the mixed nuts
10) We have:
- 25 × 64% = 16 mangoes
- 25× 16% = 4 avocados
