Step-by-step explanation:
w+ý=z/y
<span>Time (weeks) 0 1 2 3 4 5 6 7 8
</span><span>Weight (lb) 150 144 143 141 140 137 137 132 129
</span>
<u>Change in time (weeks)</u> = <u> 5 - 0 </u> = <u> 5 </u> = -0.3846
Change in weight (lbs) 137 -150 -13
The average rate of change of weight with respect to time over the first five weeks of the program is -0.3846. It is a negative sign because the weight is decreasing.
The mean of the discrete distribution that models this situation is of 2.98.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
Considering the table, the probability distribution is given by:
Hence the mean is given by:
E(X) = 4 x 0.4 + 3 x 0.32 + 2 x 0.17 + 1 x 0.08 + 0 x 0.03 = 2.98.
