The answer is the last one; to express very large or small numbers.
We use it so we can show big or very small numbers in an easier way.
Answer:
The correct answer is there are 15 samples each of size 4 to choose from the population and the population mean is 27.
Step-by-step explanation:
Total number of lottery tickets = 6
Number of samples of size 4 that can be drawn from this population of 6 lottery numbers are = ![\left[\begin{array}{ccc}6\\4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D6%5C%5C4%5Cend%7Barray%7D%5Cright%5D)
= 15.
Now the population mean is given by 
× ∑ x , where n is the number of lottery tickets and ∑ x is the sum of the lottery numbers.
Summation of the lottery ticket numbers is 162
Thus the population mean is given by 
= 27.
Answer:
the answer is b.11
Step-by-step explanation:
Y - 5 = -2x - 4
Add 5 on both sides.
y = -2x + 1
y = -2x + 1 is in simplest form.
Answer:
Formula for circumference of a circle;
C = 2πr
To find the radius, we must find half(1/2) of the diameter.
Since we are given 6, we would find 1/2 of 6 which is <u>3</u>.
Now let's plug in these values into the formula:
C = 2πr
C = 2 x 3.14 x 3
C = 18.84 feet
