1 answer:
olga55 [171]3 years ago
3 0

Answer:

10

Step-by-step explanation:

This means that 12/(2x+1)=8/(x+4). Cross multiply to get 16x + 8 = 12x + 48. Subtract 12x + 8 from both sides to get 4x = 40, so x = 10.

True or false: a mosaic plot is useful for visualizing the relationship between a numerical and a categorical variable.
Ivahew [28]

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>

mel-nik [20]

Answer:244.8

Step-by-step explanation:

15% of y=36.72

15/100 x y=36.72

15y/100=36.72

Cross multiply

15y=36.72 x100

15y=3672

Divide both sides by 15

15y/15=3672/15

y=244.8
