The Number Of Writing Instruments In Some Teachers' Desks Is Displayed In The Dot Plot. Which Is Greater

Answers

Answer 1

The median is greater than the mean. From the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean.

In the given chart we can deduce the following;

number of instruments that is 5 = 1number of instruments that is 6 = 1number of instruments that is 7 = 1number of instruments that is 8 = 1number of instruments that is 9 = 3number of instruments that is 10 = 4number of instruments that is 11 = 2number of instruments that is 12 = 1

These numbers can be listed as follows;

5, 6, 7, 8, 9, 9, 9, 10, 10, 10, 10, 11, 11, 12

The median of these numbers is calculated as;

[tex]median = \frac{9+ 10}{2} = 9.5[/tex]

The mean of these numbers is calculated as;

[tex]mean = \frac{5+6+7+8+9+9+9+10+10+10+10+11+11+12}{14} = 9.07[/tex]

Thus, the median is greater than the mean.

Also, from the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean. But if the distribution is skewed to the right, the mean is always greater than the median.

The quotient of 9 more than the radius, r, and 6

Answers

Answer:

(9 + r)/6

Step-by-step explanation:

so i'm struggling with a different problem this time. 5p - 9 = 2p + 12. (keep in mind i am an 8th grader in a high school algebra 1 class so i'm pretty clueless)

Answers

Solution :

5p - 9 = 2p + 12

5p - 2p = 12 + 9

3p = 21

p = 21 ÷ 3

p = 7
5p - 9 = 2p + 12
5p - 9 - 2p = 12
3p - 9 = 12
3p - 9 + 9 = 12 + 9
3p = 21
3p/3 = 21/3
p = 7

Answer:

r =√[3V/(π h)]

Step-by-step explanation:

V = ⅓ × π r²h

=> multiplied by 3

3V = π r² h

=> find r²

r² = 3V/(π h)

=> find r

r =√[3V/(π h)]

Answer:

[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

Step-by-step explanation:

Given equation:

[tex]V=\dfrac{1}{3} \times \pi r^2 h[/tex]

To isolate [tex]r[/tex], multiply both sides by 3:

[tex]\implies V \times 3=\dfrac{1}{3} \times \pi r^2 h \times 3[/tex]

[tex]\implies 3V= \pi r^2 h[/tex]

Divide both sides by [tex]\pi h[/tex]:

[tex]\implies \dfrac{3V}{\pi h}= \dfrac{\pi r^2 h}{\pi h}[/tex]

[tex]\implies \dfrac{3V}{\pi h}=r^2[/tex]

Square root both sides:

[tex]\implies \sqrt{r^2}=\sqrt{\dfrac{3V}{\pi h}}[/tex]

As the radius is positive only:

[tex]\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0[/tex]

[tex]\implies r=\sqrt{\dfrac{3V}{\pi h}}[/tex]
