Answer:

<em>Mean: 14</em>

<em>Median: 17</em>

<em>Mode: 18</em>

Step-by-step explanation:

The <em>mean</em> of a <em>set</em> of numbers is the <em>sum</em> divided by the number of <em>terms</em>.

Arrange the <em>data</em> in an ascending order and the <em>median</em> is the middle value. If the number of values is an <em>even number</em>, the <em>median</em> will be the <em>average</em> of the two middle numbers.

The <em>mode</em> is the <em>element</em> that occurs most in the <em>data set</em>. In this case, 18 occurs 4 times.

What is | -7.9 ?<br> help

Tamiku [17]

I think you mean |-7.9| which is the absolute value of 7.9
Absolute value just means how far away it is from zero on a number line.
So the value is always positive. So the positive of -7.9 is 7.9
|-7.9|= 7.9
Good luck!

A boat uses two pontoons to float. Each pontoon consists of a cylinder with a hemisphere at each end, as shown. Find the total v

zubka84 [21]

Answer:

$Total \approx 20ft^3$

Step-by-step explanation:

Given

$h = 12ft$ --- height of the cylinder

$d =1ft$ --- the diameter of the hemispheres at both end and the cylinder

See attachment for pontoon

Required

Determine the volume

First, calculate the radius (r)

$r = \frac{1}{2} * d$

$r = \frac{1}{2} * 1ft$

$r = 0.5ft$

Next, the volume of the cylinder

$V_1 = \pi r^2h$

$V_1 = 3.14 * 0.5^2 * 12$

$V_1 = 9.42ft^3$

Two hemispheres make up a sphere. So, we simply calculate the volume of a sphere.

$V_2 = \frac{4}{3}\pi r^3$

$V_2 = \frac{4}{3} * 3.14* 0.5^3$

$V_2 = 0.52ft^3$

So, the volume of 1 pontoon is:

$V_3 = V_1 + V_2$

$V_3 = 9.42ft^3 + 0.52ft^3$

$V_3 = 9.94ft^3$

The volume of both is:

$Total = 2 * V_3$

$Total = 2 * 9.94ft^3$

$Total = 19.88ft^3$

$Total \approx 20ft^3$
