Answer:
C
Step-by-step explanation:
Dot plot is usually in the form of stem & leaf. The only difference is that, stem& leaf presents the actual values while dot plot usually represent the value in dots. Hence, we can easily generate dot plot from stem & leaf!
For (a) dot plot and box plot, dot plot presents all the data while box plot presents only the five-num statistics, namely:
1. minimum
2. 1st quartile (Q1)
3. median
4. 3rd quartile (Q3)
5. Maximum
And outliers, if any!
Thus, dot plot cannot directly generate box plot
For (b). Histogram and stem & leaf. Although both usually help us understand the skewness of data distribution, however, histogram deals with frequency distribution (counts of number of occurrence) and plotted on the intervals and stem&leaf list the values.
For (d). Even though dot plot shoots up and down like the histogram, the content is different. In dot plot, it is the actual value represented in dots. But in histogram, it is the frequency distribution of the class intervals.
Create a dot plot of the data shown below. 20, 21, 21, 25, 20, 23, 27, 23, 24, 25, 26, 24, 23, 22, 24 Which measure of center wo
Dvinal [7]
The mean would be best, because the data distribution is nearly symmetrical
<u>Answer:</u>
The correct answer option is b. 560 units.
<u>Step-by-step explanation:</u>
We are given a prism with a base area of 40 square units and a height of 14 units.
We know the formula for the volume of the prism:
<em>the volume of a prism = Bh</em>
where <em>B</em> is the base area of the prism; and
<em>h</em> is the height of the prism.
Substituting the given values in the formula to get the volume:
Volume of prism = 40 x 14 = 560 units
Answer:
(5a+4c)(2a-b)
Explanation:
Given the expression:
First, group the expression into two:
• In the first group, 5a is a common factor.
,
• In the second group, 4c is a common factor.
Factor these out by dividing each term by the GCF of each group.
Since the terms inside the brackets are the same, combine:
CHECK
To check if your result is correct in cases like these, expand as follows:
Our result is the same as the original question, hence, the work is correct.
Answer:
x = -y + 7
or
x = 7 - y
Step-by-step explanation:
x + y = 7
Step 1: Subtract y from both sides to get x alone.
x + y = 7
-y -y
x = 7 - y
Since x is alone and y is a variable & not a number, there's nothing else to do to the equation.
