Answer:
0.75
Step-by-step explanation:
Z-score tells the no. of standard deviations a data point is from the mean.
the formula for z score is given by
z-score= (data value - mean) / standard deviation
Given:
mean=44
standard deviation= 8
data point=50
putting the values of mean(44), standard deviation(8) and given data value(50) in the above equation
z-score= (50-44)/8
= 6/8
=0.75 !
It is the last answer. because the shaded part is above the line, it is greater than. the slope is 1/3. that leaves only one more equation remaining, so the answer is the last one.<span />
1.5, 2.25, 3.375, 5.0625, 7.59375... and so on
