Answer:
60 lb. 17 oz
Step-by-step explanation:
Just add each same values together.
Given:
A parallelogram with base c, height h and other side a.
yds
yds
yds
To find:
The area of the parallelogram.
Solution:
The area of a parallelogram is:

In the given parallelogram, the base is
yds and the height is
yds. So, the area of the parallelogram is:


Therefore, the area of the parallelogram is 5200 square yds . hence the correct option is A.
The second pair because the ratios between the sides are equal
Answer:
$43 million
Step-by-step explanation:
<h3>Step 1. Turn the sentence into an equation (total = T)</h3>
15.4 million = 0.36 (T)
<h3>Step 2. Solve for T </h3>
15,400,000 / 0.36 = T
42,777,777.78 = T
$42.8 million ≈ $43 million (rounded)
The final answer rounded to the nearest million is $43 million. This makes sense since $15.4 was only 36% of this total. Checking our math, 36% of $43 million is $15.4 million!
Hope this helps :)
Formula for standard deviation sample calculation is:
SD = sqrt (( ∑( x - m)²) / ( n - 1 )),
where x stays for each value in the data set, m stays for mean of all values in the data set, and n stays for the number of values in the data set.
For example: Find the sample standard deviation for the set of numbers: 10, 11, 11, 12, 12.
First we will find mean of all avlues: m = ( 10 + 11 + 11 + 12 +12 ) / 5 = 11.2
SD = sqrt (( 1.2² + 0.2² + 0.2² + 0.8² + 0.8² ) / ( 5 - 1 ))=
= sqrt ( 2.8 / 4 ) = √0.7 = 0.837
