Answer:
35 possible combinations would be there.
Step-by-step explanation:
We have total of seven students we have to choose three out of those seven
n is the total possibilities n =7 in the given case
And r is the chosen ones
Hence, r=3 in the given case.
Substituting the values of n and r in the formula we get
Using n!=n(n-1)----1
Cancel the common factor we get
possible combinations would be there.
Answer:
The answer would be 11/2
Step-by-step explanation:
Answer: a. .7
Step-by-step explanation:
Multicollinearity means the two or more explanatory variables in a multiple regression model are highly linearly related to each other.
Multicollinearity is a problem because
- it weaken the statistical significance of an independent variable.
- Larger the standard error of a regression coefficient, the less likely it is that this coefficient will be statistically significant.
Multicollinearity may cause problems if the absolute value of the sample correlation coefficient for two of the independent variables exceeds 0.7.
So, the correct option is a. .7 .
Answer:
11 pennies and 9 nickels
Step-by-step explanation:
Set up a system of equations where p is the number of pennies and n is the number of nickels:
p + n = 20
0.01p + 0.05n = 0.56
Solve by substitution by rearranging the first equation:
p + n = 20
p = 20 - n
Then, plug this in as p into the second equation, and solve for n:
0.01p + 0.05n = 0.56
0.01(20 - n) + 0.05n = 0.56
0.2 - 0.01n + 0.05n = 0.56
0.2 + 0.04n = 0.56
0.04n = 0.36
n = 9
Then, plug this into the first equation to solve for p:
p + n = 20
p + 9 = 20
p = 11
So, Jayden has 11 pennies and 9 nickels
