The sum of 3 and the quotient of y and 2.
Step-by-step explanation:
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.
Solution
Distance in km = 2.8 km
Distance in m = 2.8 x 1000m
Distance in m = 2,800m
A. length = meter = m (base)
b. volume = cubic meter = m³ (derived)
c. mass = kilogram = kg (base)
d. temperature = kelvin = K (base)
It is - 16 because adding two negatives give you a negative
