How would I find the mean, median and mode ?
snow_tiger [21]

Answer:

Mode is the number that occurs most often in the data set. lets say i have the numbers(6,9,2,0,3,2,1,2) it would be two because there are more two's than any other number in the data set.

Mean is found by adding all of the numbers together in the data set. you simply add your numbers together.

Median is the number that is found halfway in the data set. for example if i had the numbers (6,9,2,5,0,2,1) the median would be 5.

I hope this helps you!

Alchen [17]

Answer:

14a + 20

Step-by-step explanation:

8(a + 2) + 2(2 + 3a)

expand the bracket

8a + (8*2) + (2*2) + (2*3a)

8a + 16 + 4 + 6a

bring like terms together

8a + 6a + 16 + 4

14a + 20

Find the volume of the composite figure below:<br> 5 in<br> 8 in<br> 6 in<br> 10 in
inysia [295]

Answer:

716in³

Step-by-step explanation:

The first step is to split the full prism into two, separate prisms. That means, we now have to find the volume of the half-a-cylinder, and the other base prism.

For the volume of the half-cylinder, we use the formula πr²h. That means, we do π·5·5·6, which is equal to around 471.24 cubic inches. However, we need to find the volume of half that cylinder, so we divide that answer by two. That should be about <u><em>235.62 cubic inches.</em></u>

For the volume of the other prism, we simply have to do length <em>times</em> height <em>times </em>width, or 6·8·10. That is equal to <em><u>480 cubic inches</u></em>, which is the volume of that prism.

To find the volume of the whole composite figure, you simple have to add the two underlined volumes above.

235.62+480= 715.62in³, or about <em><u>716in</u></em><em>³.</em>

<u><em>Hope this helps.</em></u>

Sasha places an online order. In addition to the price of the item she orders, she pays 5% tax and a flat shipping fee of $15. T
natita [175]

Answer:

  • $120

Step-by-step explanation:

Let the price is x.

<u>Set the equation and solve for x:</u>

  • (x + 5%) + 15 = 141
  • 1.05x + 15 = 141
  • 1.05x = 126
  • x = 126/1.05
  • x = 120
