Answer:
a. 1965
b. 8 years
Step-by-step explanation:
For answers to questions like these it can work to consider the smallest possible dataset.
<h3>Dataset</h3>
For our purpose, consider the 9 years/values to be averaged to be ...
1, 2, 3, 4, 5, 6, 7, 8 ,9
<h3>Observations</h3>
a. The center value of the data set is 5. Its number is 5-1=4 more than the first one.
The first centered value is from the year 1961 +4 = 1965.
b. The 4 values at the beginning, and the 4 values at the end do not have a corresponding "average" value. That is, 4+4 = 8 values in the series are lost with respect to the number of average values.
8 years of values are lost.
Answer:
3 + 6 + 12 + 24 + ⋯ is the corresponding geometric series. The sum of a geometric series can be determined using the formula: = 1( − 1)
Step-by-step explanation:
Answer:
<h2>BC = 39</h2>
Step-by-step explanation:
Use the Pythagorean theorem:
We have
Substitute:
Answer:
3(-9+17)
Distributive property:
3*-9
3*17
3 times -9 is -27
and 3*17 is 51
you are left with -27+51
now you add and get 24
you could also use PEMDAS
do 3(8)
and get 24
So your answer is 24, Hope that helps!
