Answer:


Step-by-step explanation:
Given


Solving (a); Point estimate of mean
To do this, we simply calculate the sample mean




Solving (b); Point estimate of standard deviation
To do this, we simply calculate the sample standard deviation





<em>Note that: The sample mean and the sample standard deviation are the best point estimators for the mean and the standard deviation, respectively.</em>
<em>Hence, the need to solve for sample mean and sample standard deviation</em>
Answer:
-80\112 = -5\7
we divided both numbers by 16
Answer:
<h3>2</h3>
Step-by-step explanation:
The value of pi is 22/7
Expressing as a decimal, the first ten digits of pi is 3.1415926535
The value in the tenth digit of the pi is 5 (tenth value after the decimal point)
The value of the ones is 3(The value before the decimal point)
The difference between both values = 5 - 3
The difference between both values = 2
Hence the difference of the ones and the tenth digit of the pi is 2
Answer:
w= 6
Step-by-step explanation:
I just started by making an educated guess using the values already given. Then I inserted that into the problem to see if it worked.
L= 2w - 5
I used 6 as a random, educated guess for the value of w.
L = 2(6) - 5
L = 12-5
L = 7
Then, multiply L by 2 to account for both side lengths of the rectangle.
7(2)= 14
Subtract that value from the total perimeter to find what the width must equal.
26 - 14 = 12
Divide that answer by 2 since there are two sides for width.
12/2 = 6
I know this was kind of long, but I hope it helps! :)
The number with the same value as 32 tens is 320.
