Answer:

480 inches³

Step-by-step explanation:

To see how much space is inside something we need to calculate the volume.

A shoe box is a rectangular object

∴Volume of a rectangle=(Length×Width×Height)unit³

=(10×6×8)inches³

=480 inches³

What is the standard deviation of the data set? Round to the nearest tenth if needed. 2, 4, 7, 8, 9

Hiiiiiiii, okay here's the full- explanation for you, so here's the final answer. The explanation of how i got the answer is also below! Hope this helped you!!

Answer:

2.9

Step-by-step explanation:

First the mean or average = sum / data points (or N) = (2 + 4 + 7 + 8 + 9) / 5 = 6

Now we take each of the individual values subtract the mean, and then square them, and add it all up.

(2 - 6)^2 + (4 - 6)^2 + (7 - 6)^2 + (8 - 6)^2 + (9 - 6)^2 = 34

Then we divide this by degrees of freedom = N - 1 to find the sample standard deviation. Note that this is different from the population standard deviation, where we would just divide N, but we use this because our data set is small, like less than 30 points.

34 / (N - 1) -----> = 34 / (5 - 1) = 8.5

Now, this is the variance, so we take the square root of the variance to get the sample standard deviation:

√(8.5) = 2.9 (rounded to 1 decimal place)

Note that scientific calculators, even my $20 version can do these kind of statistics calculations. Just enter the data set as a table of values in statistics mode, and press a few buttons, you're done!

What is the area of the figure?

Archy [21]

Answer:

The total area= area of the rectangle+ area of triangle

Area of rectangle =base *height =5*(1/3)=5/3

Area of triangle=0.5 *base* height = 3.66*0.5*2= 3.66

The total area= 3.66+5/3 =5.33 feet^2

rosijanka [135]

Answer:

4.) Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)

Step-by-step explanation:

o and p are supplementary angles, and therefore add up to 180 degrees.

Take a look at the figure. What are the coordinates of the point labeled A in the graph shown? A. (2, 2) B. (–2, 2) C. (2, –2) D

vodka [1.7K]

Hello. There was no figure to look at so I plotted all of these points for you. Which one looks like the figure to you? That will be your answer.

Remember, you plot the first number first, which will be along the X axis on a graph. Thats the line that runs right to left.

Then you plot the second number, which will be along the Y axis on a graph.
Thats the line that runs up and down.

If you go down or to the left, you will have a negative point. If you go up or to the right you will have a positive point.

(12 points)

koban [17]

Step-by-step explanation:

a.)Buying: total cost

Total cost= commission + (price per share× Number of of shares ) ;

Total cost= 11 + (19.72×30)= $591.6+11= $601.6

b.)Net gain or loss;

First, find cash received from sale of stock and deduct commission;

Cash from sale =20.75×30= $ 622.5

deduct commission= 622.5-11= $611.5

Gain or loss= sale-cost = 611.5-601.6 = $9.9, meaning there is a profit.

c.) Annual rate of return= (net gain or loss/amount paid)×100%

return= 9.9/(601.6)×100 = 1.645%
