Answer:

In order to calculate the sample deviation we need to calculate the mean given by:

And replacing we got:

And the standard deviation can be calculated with this formula:

And replacing we got:

Step-by-step explanation:
For this case we have the following data given:
281, 269, 259, 265, 256, 259, 266
The range is defined as:

And if we replace we got:

In order to calculate the sample deviation we need to calculate the mean given by:

And replacing we got:

And the standard deviation can be calculated with this formula"

And replacing we got:

Answer:
m = 0
Step-by-step explanation:
(5, 0) (-3, 0)
m = slope
m = y2 - y1 ÷ x2- x1
m = 0 - 0 ÷ -3 -5
m = 0 ÷ -8
m = 0
7 and 10 is half
so we expect the people come to wedding half of 120÷2=60 people
i just try
There are three terms. :)
Answer:
The temperature at the end of the day is 2 degrees
Step-by-step explanation:
Here, we are interested in calculating the temperature at the end of the day.
In the question, we are told that at the beginning of the day, temperature was -14 degrees.
But throughout the day, the temperature increased by 16 degrees;
Thus, the temperature at the end of the day = -14 degrees + 16 degrees = 2 degrees
