Answer:
A strong positive correlation
Step-by-step explanation:
A strong correlation when the correlation coefficient is close to 1 or -1. If the correlation coefficient is close to positive 1, then it is a positive strong correlation coefficient. If the correlation coefficient is close to negative 1, then it is a negative strong correlation coefficient.
Answer 15
Step-by-step explanation:
21 minus 5 is 16 munus 1 is 15 duh
Step-by-step explanation:
Effective resistance in the 30Ω and 40Ω parallel circuit = 1 / (1/30 + 1/40) = 120/7 Ω.
20Ω + 10Ω = 30Ω
Effective resistance in the 50Ω and (20Ω + 10Ω) parallel circuit = 1 / (1/50 + 1/30) = 75/4 Ω.
Now we can add the resistances up:
Effective resistance for circuit
= 120/7 Ω + 75/4 Ω = 1005/28 Ω.
Hence I = V / R
= 9.0V / (1005/28 Ω) = 0.25A. (2s.f.)
Answer: 114
Step-by-step explanation:
The value of the denominator in the calculation of the multiple standard error "MSSE' of estimate is given by "n-k-1 " , where n= Total observations , k = total independent variables such that 
Given : A multiple regression analysis is based on 10 independent variables collected from a sample of 125 observations.
i.e. Total observations : n= 125
Total independent variables : k=10
Then, the value of the denominator in the calculation of the multiple standard error of estimate would be (125)-(10)-1 =114
Therefore , the value of the denominator in the calculation of the multiple standard error of estimate = 114 .
