Answer:
This isn't that specific enough
Step-by-step explanation:
Answer:
C. The total number of movies watched categorized by science fiction vs. non-science fiction
Step-by-step explanation:
A stacked bar chart is a type of graph that is mostly used to simplify multiple parts and compare them as a whole.
It uses different "bars" and each bar represents one part of the whole and segments of that bar show the different parts or categories of the whole.
Consider option A
In this option, the total average height of men and women cannot be considered as a whole. Therefore, the stacked chart cannot be used.
Consider option B
In this option, the totak number of red cars and bicycles cannot be considered as a whole because cars and bicycles are two different kinds of sets.
Consider option C
Here, the total number of movies watched categorized by science fiction and non-science fiction can be considered a whole because science and non-science fiction movies are the same sets of data and they add up to the total number of movies.
Hence, a stacked graph is appropriate here.
Option C is the correct answer
Answer:
x=-3
Step-by-step explanation:
1-7x-7=15
We move all terms to the left:
1-7x-7-(15)=0
We add all the numbers together, and all the variables
-7x-21=0
We move all terms containing x to the left, all other terms to the right
-7x=21
x=21/-7
x=-3
Answer:
Is unbiased estimator
Step-by-step explanation:
In statistics, Numerical characteristics derived from population data is referred to as parameter, while those derived from the sample data are called statistic. When a sample is drawn from a particular population, the statistic of such sample could be used as either a point or interval estimate of the population. However, the estimator derived from the sample in most cases isn't equal to the exact parameter value. When this happens, that is, when population parameter equals the estimate of the sample statistic, then we have an unbiased estimator.
y = $185.30
x = the orignal cost minus 9% or .09. To increase an objects value by 9% you need to multiply by 1 + .09 or 1.09. So, x being increases by 9% would equal y or $185.30
1.09x = y
1.09x = $185.30
Divide both sides by 1.09
x = $170
