A researcher analyzed the results of her data and calculated the standard deviation of scores at 3.5. what is the variance?
Solution: We are given the standard deviation of scores = 3.5
We know that the variance is the square of the standard deviation.
Therefore, the variance is:
Therefore, the variance of the scores is 12.25
The first thing we must do is subtract both speeds.
We have then:
64.4 km / h - 64.0 km / h = 0.40 km / h
We now change units taking into account the following conversions:
1h = 3600s
1km = 3280.84 feets
We have then:
0.40 * (3280.84 / 3600) = 0.364537778 feet / s
Answer:
a zebra is faster 0.364537778 in feet per second
Answer:
Step-by-step explanation:
<u>Unknown value is q.</u>
<u>Solve for the unknown value:</u>
- 6 + q = 25 1/2
- q = 25 1/2 - 6
- 25 1/2 - 6
- = 19 1/2.
- q = 19 1/2.
<h2>
Answer is q = 19 1/2.</h2>
Parentheses first -4+-8= -12(1)= -12
= -12
