Answer:

43.2 cm^3.

Step-by-step explanation:

This is made up of a rectangular prism and a right triangular prism

The base of the right triangle = 4.8 - 3.2 = 1.6.

Total volume = 4 * 2.7 * 3.2 ( Volume of rectangular) + 1/2 * 1.6 * 2.7 * 4 ( triangular prism)

= 4 * 2.7 * 3.2 + 1/2 * 1.6 * 2.7 * 4

= 34.56 + 8.64

= 43.2 cm^3.

Answer:

Here are the steps to find the volume.

Step-by-step explanation:

Volume = length x width x height.
You only need to know one side to figure out the volume of a cube.
The units of measure for volume are cubic units.
Volume is in three-dimensions.
You can multiply the sides in any order.
Which side you call length, width, or height doesn't matter.

Answer:

Step-by-step explanation:

it is 18 because you would 36 divided by 4 to get 9. Then you would do 9 plus 6 to get the answer 18

Find and interpret the mean absolute deviation of the data.

Zinaida [17]

Answer:

The mean absolute deviation is 4

Interpertation: The average distance between each data value and the mean is 4 which is the variation in the data set so you can understand how "spread out" each data point is from each other

Step-by-step explanation:

The mean absolute deviation is a measure of how much a data set varies.

Step 1: Compute the mean

mean = the sum of all the terms / number of terms

mean = 94 + 86 + 95 + 99 + 88 + 90 / 6

= 552 / 6

= 92

The mean is 92

Step 2: Finding the absolute deviation

You would take each number in the data set and subtract it from the mean, take the absolute value. After you take the sum of the absolute data values

= |94 - 92| + |86 - 92| + |95 - 92| + |99 - 92| + |88 - 92| + |90 - 92|

= |2| + |- 6| + |3| + |7| + |- 4| + |- 2|

= 2 + 6 + 3 + 7 + 4 + 2

= 24

To find the mean absolute deviation you divided the sum by total number of terms...

24/6 = 4

The average (mean) is equal to the sum of all the data values divided by the count of values in the data set (which was step 1)

slope = rise over run = y/x

A (-1,3) slope = 3/-1 = -3

B (1,2) slope = 2/1 = 2

C (-3,-1) slope = -1/-3 = 1/3

2 lines need to be negative reciprocals in order to be a right triangle

negative reciprocal of -3 is 1/3

so this is a right triangle

PLEASEEE HELP Questions 4 and 5

Ilya [14]

Answer:

Given and explained below.

question 4

using sine rule:

$\sf sinx = \frac{opp}{hyp}$

$\sf sinx = \frac{11}{13}$

$\sf x = sin^{-1}(\frac{11}{13} )$

$\sf x = 57.8$

question 5

using cosine rule:

$\sf cosx =\frac{adj}{hyp}$

$\sf cos(31) =\frac{x}{17}$

$\sf cos(31)*17 =x$

$\sf x = 14.6$
