Answer:
0.195
Step-by-step explanation:
Given:
For ; sample size, n = 9 ;
Standard Error (S. E) = 0.39
S. E = σ / sqrt(n)
σ = standard deviation
0.39 = σ / sqrt(9)
σ = 0.39 * 3
σ = 1.17
Therefore, For n = 36
S. E = 1.17 / sqrt(36)
S.E = 1.17 / 6
S.E = 0.195
40m to the 2nd power when doing the math its 40m to the 2nd power and then you get ur answer :)
Answer:
First do 6+7 (PEMDAS), plus 2 and then plus 54
2+(-11) is -9
Hence, -45 is the number which when added to the given fraction will give 2/3
Further explanation:
Given fraction is:

Let x be the number which has to be added to numerator and denominator
Then

Cross-multiplying

Hence, -45 is the number which when added to the given fraction will give 2/3
