Consider a normally distributed data set with a mean of 154 and a standard deviation of 9.8. if one of the observed values is 176, what is the z score?

z score = 2.24

Step-by-step explanation:

A normally distributed data set is given with a mean of 154 standard deviation 9.8.

If one of the observed value is 176, then we have to calculate the z-score.

z value =

z score =

            = = 2.24

z score = 2.24

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

if you was gonna solve for a, a is a   < -12
