Answer:

D) None of the above

Step-by-step explanation:

This is because all of the shapes above are examples of 3D shapes. A 3D shape would have the dimensions of length and width and height. However a 2D shape would only have the dimensions of length and width.

An example of a 2D shape is a rectangle. as it consists of a length and a width, but does not have a height.

On the other hand a £D shape such as a cube would have a length, width and a height.

1. What is the mean change in the forecasted high temperatures over the next 7 days?
12345 [234]
For this question you will have to find your own set of data for your area, just go to weather.com or a similar site and make a set of temperatures for the next 7 days in your area. The mean can be found by adding all temperatures, then dividing their sum by the number of objects being added. 
For example, if my set of temperatures were {75, 90, 83, 77, 91, 88, 80}, I would find the mean with the equation (75 + 90 + 83 + 77 + 91 + 88 + 80)/7, or 83.4

Draw a modelto show that x + 3 is the same as x over 3​
Shalnov [3]

Answer:

Step-by-step explanation:

Your equation comes out to x + 3 = x/3.  Multiplying all three terms by 3 results in 3x + 9 = x, which simplifies to 2x = -9, so that x = -9/2.

Unsure of what you're asking for by "model."

The price of a train ticket consists of an initial fee plus a constant fee per stop.
murzikaleks [220]

Answer:

Initial Fee is $2.

Step-by-step explanation:

Given:

Stops  Price (dollars)

3         6.50

7         12.50

11         18.50

Also Given:

The price of a train ticket consists of an initial fee plus a constant fee per stop.

So let the Cost of initial fee be 'x'.

Also Let the Cost of Constant fee be 'y'.

Now Equation can framed as;

Price (P) = x + (y\times \textrm{Number of Stops})

Now According to table;

Number of stops = 3

Price = 6.50

So equation can be framed as;

x+3y =6.50 \ \ \ \ equation \ 1

Also According to table;

Number of stops = 7

Price = 12.50

So equation can be framed as;

x+7y =12.50 \ \ \ \ equation \ 2

Now Subtracting equation 1 from equation 2 we get;

(x+7y)-(x+3y) =12.50-6.50\\\\x+7y-x-3y=6\\\\4y =6\\\\y= \frac{6}{4}=\$1.5

Substituting the value of y in equation 1 we get;

x+3\times1.5=6.50\\\\x+4.5=6.50\\\\x =6.50-4.5 = \$2

Hence Initial Fee is $2.
