What is the answer 8/5-1/6= ive been stuck on this question forever
Leviafan [203]

Answer:

1 13/30

Step-by-step explanation:

First you want to make the denominators the same.  You do this by multiplying them.  However, whatever you do you to the denominator, you must also do to the numerator:

\frac{8x6}{5x6}-\frac{1x5}{6x5}=\frac{48}{30}-\frac{5}{30}=\frac{43}{30}

Now reduce to simplest terms:

\frac{43}{30}=1\frac{13}{30}

1. The mean number of siblings for respondents in a survey is 3.76 with a standard deviation of 3.18. Calculate the Z score asso
allsm [11]

Answer:

-0.24 ; 0.71

Step-by-step explanation:

Given that :

Mean number of siblings (m) = 3.76

Standard deviation (s) = 3.18

Z score associated with 3 siblings

x = 3

Using the relation :

Zscore = (x - m) / s

Zscore = (3 - 3.76) / 3.18

Zscore = - 0.76 / 3.18

Zscore = −0.238993

Zscore = - 0.24

2.) proportion of respondents with more than 2 siblings

Using the z probability calculator :

X > 2

Obtain the standardized score :

Zscore = (x - m) / s

Zscore = (2 - 3.76) / 3.18

Zscore = - 1.76 / 3.18

Zscore = −0.5534591

Zscore = - 0.55

Using the z table :

P(Z ≥ - 0.55) = 1 - p(Z ≤ - 0.55) ; p(Z ≤ - 0.55) = 0.2912

1 - p(Z ≤ - 0.55) = 1 - 0.2912 = 0.7088 = 0.71
