I think what you need to do here is do the volume of a cone. Which is 1/3 pir^2h. The first step is to find the radius. In order to do that is to divide the diameter by 2. You do this because the radius is two times smaller than the diameter. Then you want to multiply the radius (which is 6 inches) by the height (12 inches). By this time you should have the number 72 (12x6). The next step is to multiply 72 by pi, or 3.14. Which is 226.08.  I hope that you realized that all is left in the formula is the fraction 1/3. What you do here is divide the sum, or what you have multiplied. So, 226.08 divided by 3 is 75. 36. The model should be 75.36 inches.

For which intervals is the function negative
Mice21 [21]

ANSWER

(1,4)

(- \infty ,-3)

EXPLANATION

The x-values for which the graph is below the x-values below the x-axis is the interval on which the graph is negative.

We can see from the graph that, for

x <  - 3

the function is negative.

This can be rewritten as:

(- \infty ,-3)

Also for

1 < x < 4

the function is again negative.

This is also written as:

(1,4)

Find the range median first and third interquartile range for each data set
liraira [26]

Answer:

Range = 1.8

Median = 6.3

First Quartile = 6.3

Thrid Quartile = 6.8

Interquartile Range =  0.5

Step-by-step explanation:

First we need to arrange the data set from lowest to highest.

4.9, 5.8, 6.1, 6.2, 6.3, 6.3, 6.4, 6.6, 6.7, 6.7

To find the range of the data set, we simply take the highest value and subtract it to the lowest value.

Range = 6.7 - 4.9

Range = 1.8

To find the Median we need to get the middle number of the range. In this case there are two numbers in the middle of the set.

So we get both of them and get their average.

Median = 6.3 + 6.3 /2

Median = 6.3

To get the first quartile, we simply get the median of the lower of the data set.

4.9, 5.8, 6.1, 6.2, 6.3

The median of the first quartile is 6.1.

To get the third quartile, we get the median of the upper half of the data set.

6.3, 6.4, 6.6, 6.7, 6.7

The median of the third quartile is 6.6

To get the interquartile range, we need to subtract the median of the third quartile to the median of the first quartile.

Interquartile Range = 6.6 - 6.1

Interquartile Range = 0.5

Answer:

Range = 32

Median = 17.5

First Quartile = 15

Thrid Quartile = 19

Interquartile Range =  4

Step-by-step explanation:

First we need to arrange the data set from lowest to highest.

4, 9, 15, 16, 17, 18, 18, 19, 19, 36

To find the range of the data set, we simply take the highest value and subtract it to the lowest value.

Range = 36 - 4

Range = 32

To find the Median we need to get the middle number of the range. In this case there are two numbers in the middle of the set.

So we get both of them and get their average.

Median = 17 + 18 /2

Median = 17.5

To get the first quartile, we simply get the median of the lower of the data set.

4, 9, 15, 16, 17,

The median of the first quartile is 15.

To get the third quartile, we get the median of the upper half of the data set.

18, 18, 19, 19, 36

The median of the third quartile is 19.

To get the interquartile range, we need to subtract the median of the third quartile to the median of the first quartile.

Interquartile Range = 19 - 15

Interquartile Range = 4
