21 ounces
Step-by-step explanation:
2 pounds→ convert to ounces= 32
32 ounces+ 3 ounces= 35
56 ounces-35 ounces= 21 ounces
The height & speed are mathematically given as
t = 0.2 s
u = 4 m/s
<h3>What is the
height & speed?</h3>
Generally, the equation for height is mathematically given as
h = 0.2gt^2
Therefore
0.2 = 0.5 * 9.8 *
0.2 = 4.9 *
t = 0.2 s
b)
In conclusion, the initial speed is
s = ut
Therefore
u = 0.8 / 0.2
u = 4 m/s

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.
