Find the possibility of rolling even numbers three times, using a six-side die number from 1 to 6

Mathematics
1 answer:
seraphim [82]3 years ago
5 0

Answer:

\frac{1}{8}

Step-by-step explanation:

Number of sides of die = 6

Number of sides with even numbers = 3

P( rolling an even number 1 time) = \frac{3}{6} = \frac{1}{2}

P(rolling even number 3 times) = \frac{1}{2} x \frac{1}{2}  x \frac{1}{2} = \frac{1}{8}

a triangle has two sides that are 2 inches and 12 inches what could be the length of the third side of the triangle
Salsk061 [2.6K]
Hmm, let's see. Well a triangle's dimensions add up to 180. If both sides given add up to 14. Simply subtract 180 by 14. You get, 166. If I'm wrong, feel free to correct me on that :)

What is the multiplicative identity matrix? What is it similar to in the set of real numbers? Explain your answer
bagirrra123 [75]

Answer:

An identity matrix, is a matrix that have '1' in the main diagonal. All of the other terms are '0'. When you multiply any matrix by the identity matrix, the result is the same matrix that you multiplied.

Example:

\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]

In the set of the real number is the same that the application of identity property.

Every number multiplied by 1 es the same number.

40.51x+12.45y=666.64
irga5000 [103]

Answer:

The graph of the equation 40.51x+12.45y=666.64 is attached with the answer where the horizontal axis represents the X axis and the vertical axis represents Y axis.

To plot the graph physically just find two points lying on the line. Mark the points on the graph sheet and then join them. This will give you the line represented by the equation.

To find points on the line assume the value of any one variable, substitute it in the equation, then solve the equation to find the value of other variable. For example : assume y = 1; substitute the value of y in the equation;

⇒ 40.51x + 12.45×1 = 666.64

⇒ 40.51x = 666.64 - 12.45

⇒ 40.51x = 654.19

⇒ x = \frac{654.19}{40.51}

⇒ x ≈ 16.149

Therefore point ( 16.149 , 1 ) lie on the graph of the equation.

***Only two points are required to plot this graph just because it represents a straight line, that we can conclude just by observing the equation. If in an equation the power of x is 1 or 0 and power of y is 1 or 0 then only it will represent a straight line in 2-D plane.***

A train traveled 325 miles in 5hrs. What was the trains average rate of speed in miles per hr ?
Leya [2.2K]

Hi there!

To find the average speed of a moving object all you need to do is divide the distance traveled by the object by amount of time it took the object to reach its final destination. So for this problem it would go like this:

325 ÷ 5 = 65

So for this problem in particular the answer is 65 MPH was the average speed of the train.
