Answer:
The answer is 21 if you use PEMDAS.
If you are referring to the common factors:
Factorize both numbers:
48 = 2*2*2*2*3
120 = 2*2*2*3*5
Common factors: 1, 2, 3, 4, 6, 8, 12, 24
If you are referring to factors in general:
48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
Answer: C. ±0.632.
Step-by-step explanation:
We have given,
Sample size : n= 10
Significance level : ![\alpha=0.05](https://tex.z-dn.net/?f=%5Calpha%3D0.05)
Test to check determine whether there is sufficient evidence to support a
claim of a linear correlation between two variables is a two tailed test.
Degree of freedom(df) = n- 2=8
Now , by the correlation coefficient(r) table ,
The critical r value corresponding to df = 8 and Significance level = 0.025 (0.05/2) is ±0.632.
Hence, the correct option is C. ±0.632.
10≡x x=1, 2, 5, 10
So the set A={1, 2, 5, 10}
