Answer: Option (D) is the correct answer.
Step-by-step explanation:
A data that describes or tells what it is about or what is shows is known as descriptive statistic.
A descriptive statistic helps in summarizing a set of data which can be representation of the entire or sample of a population.
It basically provides a meaning to the information described by the data.
Thus, we can conclude that a statistic that describes a sampled group is called descriptive.
<span>a. 7 fireflies are caught per minute.
b. 19 fireflies were already caught prior to the contest starting.
a.
Looking at the equations (3m + 13) and (4m + 6) where m is equal to the number of minutes since the contest began, it's obvious that there are 3+4 = 7 fireflies caught per minute.
b.
One again, look at the two equations. Or for that matter, calculate them both and add the results for m=0 (the moment the contest began). And upon doing so, you'll see that 13 + 6 = 19 fireflies were caught prior to the competition starting.</span>
The mean is 10,724.28.
Explanation:
The mean is all of the values divided by the number of values there are.
So what you have to do is add all of the numbers and divide it by the amount of numbers there are.
10,150+10,211+10,424+10,769+10,884+11,155+11,477= 75,070.
Since there are 7 numbers, divide 75,070/7 and you get your mean, which is 10,724.28 rounded.
For a rectangular prism, V = lwh.
First choice: 2*2*12 = 48, so this is possible.
Second choice: 2*4*6 = 48, so this is possible.
Third choice: 3*2*8 = 48, so this is also possible.
Fourth choice: 4*3*3 = 36, so these cannot be the dimensions of the prism.
The fourth choice is the correct answer.
