It is false that for visualizing the relationship between a numerical and a categorical variable, a mosaic
plot is useful. This is because the best plot to use for this kind of
relationship is the side by side box plot.
Comparing the
distribution of a numerical variable across the levels of a categorical
variable is something we usually consider in this type of relationship.
The levels of one categorical variable by means of a quantitative
variable is best compared by using the visual display called the side by side
boxplot. <span>By placing single boxplots adjacent to one
another on a single scale, the side by side box plot is constructed.</span>
Answer:
Step-by-step explanation:
<u>There are 3 angles:</u>
<u>There is 1 missing angle:</u>
<u>Subtract 180°:</u>
- 180 - 60 = 120 - 90 = 30.
<u>Missing angle found!</u>
<u>Missing angle:</u>
Answer:
7+2(a-3)=-9
a= -5
Step-by-step explanation:
7+2(a-3)=-9
<u>Distribute</u><u> </u> 2 through the parentheses
<u>Example</u><u>:</u> 7+2a-6=-9
Next: 7+2a-6=-9
Subtract the numbers
1+2a=-9
Move constant to the right hand side and change its sighn 2a=-9-1
<u>2a</u><u>=</u><u>-9-1</u>
<u>Calculate</u><u> </u><u>the</u><u> </u><u>difference</u><u> </u>
2a=-10
<u>Divide</u><u> </u><u>both</u><u> </u><u>sides</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>equation</u><u> </u><u>by</u><u> </u><u>2</u>
<u>Answer</u><u>:</u><u> </u>a=- -5
Answer:
The right answer is: Option C: x+5
Step-by-step explanation:
Let m1 be the miles Lukas drove on Saturday and Let m2 be the miles he drove on Sunday

The difference can be found out by subtracting m2 from m1
minus sign will be distributed into the bracket and alike terms will be added or subtracted according to sign.

The difference of miles driven is: x+5
Hence,
The right answer is: Option C: x+5
Answer: 87%
Solution:
87 correct questions over 100 = 87/100 = .87 = (change to percent by moving the decimal 2 places to the right) 87%
