Answer:
2x2 = 4
step-by-step explanation:
2 two times makes 4
4/5 = 80%
2/3 = 66.66666...%
4/5 is a bigger fraction, so (4/5) x 45 is a bigger fraction.
D=51/77
First set up the equation equal to zero(0), the distribute from there.
The greatest common factor of 10 and 20 is 10.
Solution: We are given:
μ=180,σ=25,n=100
Therefore the standard error of the mean is
