Answer:
0.125 or 1/8
Step-by-step explanation:
2^3 +2^-3= (2*2*2) + (1/(2*2*2))= 8 + 1/8= 8 + 0.125= 8.125
4^3 +1= (4*4*4) + 1= 64 + 1= 65
8.125/65= 0.125 or 1/8

Answer:
2^-15 or 1/2^15
Step-by-step explanation:
3*-5 is -15 so that makes it 2^-15
Apply the exponent rule a^-b = 1/a^b
That changes it to 1/2^15
Hope this helped! :)
Answer:
The probability of selecting a sample mean of 13 or larger from this population is 0.0228
Step-by-step explanation:
A researcher selects a sample of 49 participants from a population with a mean of 12 and a standard deviation of 3.5.



We are supposed to find the probability of selecting a sample mean of 13 or larger from this population i.e.


Z=2
Refer the z table


Hence the probability of selecting a sample mean of 13 or larger from this population is 0.0228
