Widget Indutries had stock that sold at 36 5/8 points. The stock rose 7 1/4 points. What is the new price?
1 answer:
The new price of stock of Widget industries is
<u>Solution:</u>
Given that, Widget Industries had stock that sold at points.
The stock rose points.
We have find what is the new price of the stock ?
Now, we know that, new price of the stock will be combination of sold value of the stock and the new rise of points to the stock
Then, new price of the stock = sold price of stock + rise in points
Converting the mixed fractions, we get
Hence, the new price of the stock is

To find which measure of variability is greater and which average number of monthly fatalities is higher, you will need to calculate the mean and the mean absolute deviation for both years
The mean will tell us which is generally higher, and the mean absolute deviation will tell us which has a greater variability.
The correct answer is D.
Please see the attached picture for the work.

The difference in gallons per day used is 3.6.
The formula to calculate a z-score is:
,
where X is the value used to calculate the score, μ is the mean and σ is the standard deviation. We have the z-scores so we must work backward:
For both equations, we will cancel the 1.2 by multiplying both sides:
Now we will cancel 2.2 from both equations by adding it to both sides:
3.6+2.2=X-2.2+2.2 and 0+2.2=X-2.2+2.2
5.8=X and 2.2=X
The difference in gas used per day would be given by
5.8-2.2 = 3.6.
