Answer:
the inter-quartile range will increase
Step-by-step explanation:
The initial data-set was;
20,32,32,45,50
Adding a new value 78 will have several effects;
The mean of the new set of values will increase since 78 is mostly likely to be an outlier.
The median of the new data set will increase. The median of the old data set is 32 while that of the new data set will be 38.5
The mode is the most frequent observation. Both the new and the old sets of values will have a mode of 32. The mode will therefore remain the same.
The inter-quartile range just like the range will increase
Answer:
y = -2/3x
Step-by-step explanation:
To write in y=mx+b form, you need the y-intercept (b) and the slope (m).
The y-intercept is the point the line crosses the y-axis. This line crosses the y-axis of (0, 0). This makes the y-intercept equal to 0.
The slope is the rise of the line over the run of the line. Pick two points from the line. It doesn't matter which ones, you will get the right answer regardless.
I picked (0, 0) and (-3, 2). Subtract the x-values from each other, and subtract the y-values from each other.
-3 - 0 = -3 (x)
2 - 0 = 2 (y)
Divide the y by the x to find the slope.
2/-3 = -2/3
Plug in the slope and y-intercept into the equation.
y = mx + b
y = -2/3x + 0
y = -2/3x
Answer: "13,000 books" represents the population.
"200" books represents the sample.
Step-by-step explanation:
- A population is the term that denotes a whole large possible group of individuals, objects, events or measurements.
- A subset of population is known as ample.
- When population is too large to the researcher , then it uses sample to represent the entire population.
Here, "13,000 books" represents the population.
"200" books represents the sample which is a subset of 13,000 books.
Answer:
48
Step-by-step explanation:
the top shape is 6 by 6, which is 36
the bottom shape is 3 by 4, which is 12.
if you add the two areas, 12+36, you get 48. so the area of the entire shape is 48mi
Answer:
The answer is A
