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

1 answer:

3 0

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. By placing single boxplots adjacent to one another on a single scale, the side by side box plot is constructed.

Data was collected for a sample of organic snacks. The amount of sugar (in mg) in each snack is summarized in the histogram belo

castortr0y [4]

Answer:

Step-by-step explanation:

Hello!

The histogram summarizes the amount of sugar in organic snacks. (mg)

Y-axis shows the number of snacks

X-axis shows the amount of sugar per snack

The first column of the histogram show that 2 snacks contain sugar between 220 and 224 mg of sugar.

The second column shows that about 3 snacks have between 224 and 228 mg of sugar.

The third column shows that 8 snacks have between 228 and 232 mg of sugar.

The fourth column shows that 12 snacks have between 232 and 236 mg of sugar.

The fifth column shows that 11 snacks have between 236 and 240 mg of sugar.

The sixth column shows that 3 snacks have between 240 and 244 mg of sugar.

The seventh column shows that 2 snacks have between 244 and 248 mg of sugar.

The total of observations is 2+3+8+12+11+3+2= 41 snacks.

I hope this helps!

N^2-n/3=7 complete the square

monitta

Answer:

You need to add 1/36th to both sides of the equation, giving you the expression

$n^2 - \frac{1}{3}n + \frac{1}{36} = 7\frac{1}{36}\\$

Which can be expressed as:

$(n - \frac{1}{6})^2 = 7\frac{1}{36}$

Step-by-step explanation:

We need to add a term that is the the square of half the coefficient of the second term.

$n^2 - n/3 = 7\\n^2 - \frac{1}{3}n = 7\\n^2 - \frac{1}{3}n + \frac{1}{36} = 7\frac{1}{36}\\(n - \frac{1}{6})^2 = 7\frac{1}{36}$

Let's check the answer by expanding:

$(n - \frac{1}{6})^2 = 7\frac{1}{36}\\n^2 - \frac{1}{6}n - \frac{1}{6}n + \frac{1}{36} = 7\frac{1}{36}\\n^2 - \frac{1}{3}n + \frac{1}{36} = 7\frac{1}{36}\\n^2 - \frac{1}{3}n = 7$

Which verifies the answer.

Karla is given the equation 10x + 15 = 20 to solve. She says the solution is 1 2 . Which reason justifies her solution? *A) Karl

Sav [38]

C. Karla says that to solve the equation you first subtract 15 and then divide by 10.

Karla is given the equation 10x + 15 = 20 to solve. She says the solution is 1/2

10x + 15 = 20
10x = 20 - 15 (subtract 5)
10x = 5 (divide by 10)
x = 5/10 = 1/2

Anika [276]

The place for 8 in 2,384,015

is ten thousand

and it's place value is 80,000

also , 

the place for 2 in 21,729,368

is ten million

and the place value is 20,000,000

now comparing the place value for the two digits , we can say that 

the value of 2 in 21,729,368 is greater than the value of 8 in 2,384,015
