Not this is not true, -54 - -36 equals -18
Answer:
The answer is 4
Step-by-step explanation:
For a poisson distribution, the variance is equal to the mean. Since the average number of defects per product is 2, it means that the mean per product is 2. Hence for 32 units it is 16 divided by 2 which is 16.
Also, since the square root of variance is equal standard deviation, the square root of 16 is 4.
Answer:

where y is in thousands
Step-by-step explanation:
The equation in two variables that can be used to represent the situation given can be determined using computer software such Stat-Crunch or Ms. Excel or advanced calculators.
I shall use Ms. Excel for this question.
In Ms. Excel, enter the data into any two adjacent columns. Next, highlight the data, then click the insert ribbon and select the scatter-plot option.
Excel returns a scatter-plot chart as shown in the attachment below.
After obtaining the scatter-plot, we shall need to add a trend line in order to determine the mathematical equation that best fits the scenario given.
Click anywhere inside the chart, then select the design tab under chart tools. Click on the Add Chart element in the upper left corner of the excel workbook and select more trend-line options. This feature will enable us to fit any trend-line to our data.
Select the exponential option, since we were informed that he number of flip cell phones is in exponential decline,ensuring you check the box; Display Equation on chart.
Find the attached.
The equation in two variables is thus;

Answer:
$16.80 per hour.
Step-by-step explanation:
So you got 420 dollars earned last week. Jerry worked for 25 hours and if you divide.
You’d find the unit rate which is 420/25 and get 16.8.
