<span>The median is a better measure of center when there is an outlier which will make the mean not be a good estimate of the center. Option B has $1075 as an outlier (i.e. it is far away from the other data sets). Hence, the median will be a better estimate of the center. Similarly, 94 is an outlier in option C and hence, the median is a better estimate. Options A and D has no outliers, making the mean a good estimate of the centre.</span>
Answer: y = 1/8x+1
y=mx+b is slope intercept form
given m = 1/8 and a point we can find b by plugging in what we have
1=1/8(8)+b
1=1b
b=1
So then we know m = 1/8 and b = 1
y=1/8x+1 is the answer
(93+67+78+44+123)/5=405/5=81 pizzas per day on average
C is your answer.
