2.1
1.285714
Answer:
z = 1.095
Step-by-step explanation:
To calculate the value of z, it is to replace in the corresponding formula:
z = (x - m) / sd
where m, which is the mean, which has the value of 17.7
x, the sample, which would be 20
and sd the standard deviation, which is equal to 2.1
Now by replacing all the values:
z = (20 - 17.7) /2.1
Answer:OI>>>
-15
It might help to factor out the expression further. You can factor it as:
(1)(15)(-)
n = 12
Do you mean (1/4)n = 3 ?
just multiply through by 4
4n(1/4) = 4×3
Encuentro que la relación es que el poder se está multiplicando repetidamente.
