Answer:

The probability is 3/10, or 30%.

Step-by-step explanation:

A probability P is the ratio of the number of favorable (relevant) cases and the total number of all possible cases.

The probability that Red and Small is selected can be estimated using values from the table:

P(Red and Small) = #(Red and Small) / # (total) = Value(2nd row, 2nd column) / Sum (all cells in the table) = 12/40 = 3/10 = 30%.

What is the area of the figure? <br> /Users/macuser/Downloads/MS_IMB-1401012-1100604.jpg
xeze [42]
Given:
Shapes: Trapezoid and Triangle.

Trapezoid: Upper base = 14mm ; lower base = 18mm
Triangle: base = 18mm ; height = 12mm
Total height of the figure is 17 mm

Area of a trapezoid = (upper base + lower base)/2  * height
A = (14mm+18mm)/2  * (17mm-12mm)
A = 32mm/2 * 5mm
A = 16mm * 5mm
A = 80 mm²

Area of a triangle = (height * base) ÷ 2
A = (12mm * 18mm) ÷ 2
A = 216mm² ÷ 2
A = 108 mm²

Total area of the figure = 80 mm² + 108 mm² = 188mm²

What is the volume, in cubic m, of a cube with an edge length of 11m?
rewona [7]

the volume of cube with edge length 11 m is Volume = 1331m^3 .

<u>Step-by-step explanation:</u>

Here  we have a side length of a cube as 11 m . We need to find the volume of cube . Let's find out:

We know that every side of a cube is identical and equal . And volume of cube is given by formula :

⇒ Volume = (side)^3   ...........(1)

According to question we have following parameters as

side = 11m

Putting this in (1)

⇒ Volume = (11m)^3

⇒ Volume = 11(11)(11)m^3

⇒ Volume = (121)(11)m^3

⇒ Volume = 1331m^3

Therefore , the volume of cube with edge length 11 m is Volume = 1331m^3 .

A
<em>Graph g</em>
The Rate of change is a little right triangle that is drawn from to to three parallel to the x axis and from about 45 to 60 on the y axis.
The square brackets means the the endpoints are included.
So the rate of change is \frac{\Delta y}{\Delta x} =  \frac{60-45}{3 - 2} = \text{15}
<em>Graph h</em>
\text{rate of change = }  \frac{\Delta y}{\Delta x} =  \frac{35 - 20}{3 - 2} = 15
<em>Graph f</em>
\text{rate of change = } \frac{\Delta y}{\Delta x} = \frac{35 - 10}{3 - 2} = 25
<em>Conclusion</em>
This is very hard to call. There are two the same (two of them being g and h) It's a graph and so it is nearly impossible to differentiate. I would say the statement is false but be prepared to get it wrong. Draw g and h for yourself and see what you think. If you get the two of them different, go with your answer.

B
Another tough one to call. f and g cross at four. It is true f and h. The value of f(4) > h(4). Again, if you do this and disagree, then go with your answer. Mine is false.

C
It is very difficult to reproduce this graph on desmos so that you get a clear cut answer from the graph. I cheated and used a calculator. f(x) is over 6000 and h(x) = 168. This statement is also not true.

D
Here again this is false. g's rate of change is a constant. Eventually f will have the same slope as bitcoin's value which is in the range of about 6000. So this statement is false as well.

E
See the comment about F in the answer for D. This statement is true.

F
This is definitely a true statement. 

Conclusion or answer
E and F <<<<<<< True should be checked.

I would check the first two statements with a calculator. I did them with a graph.
