Step-by-step explanation:
Here, in step format, is how to solve a system with three equations and three variables:
Pick any two pairs of equations from the system.
Eliminate the same variable from each pair using the Addition/Subtraction method.
Solve the system of the two new equations using the Addition/Subtraction method.
We know that
The third quartile (also called the upper quartile) has 75 percent of the data below it and the top 25 percent of the data above it. <span>The third quartile is the same as the </span>median<span> of the part of the data which is greater than the median.
</span>
therefore
the answer is the option
<span>C.) The third quartile is the median of the upper half of data in the data set.</span>
Answer:
1 min 45 sec
Step-by-step explanation:
First convert 14 min to seconds.
14 x 60 = 840s
Now we can use ratios to find the answer
840s : 800m
Divide both sides by 8
105s : 100m
105s is 1 minute and 45 seconds
Answer:
2m
