puteri [66]

Answer:

We have to plot a graph of the function that passes through the points (0.5,3), (1.5,4), and (2.5,1).

Clearly the graph passing through the three points will form a triangle with these coordinates. we could clearly see our graph from the figure attached to the answer.

The graph passing through two given points form a line,through three points it form a triangle and through four given points it form a quadrilateral.

What is the chance of rolling a 4 with a single die four times in a row?
Anni [7]
This is the concept of probability, we are required to calculate for the probability of rolling a 4 with a single die four times in a row;
To solve this we proceed as follows;
The probability space of a die is  x={1,2,3,4,5,6}
The probability of a die falling on any of this number is:
P(x)=1/6
Thus the probability of rolling a 4 with a single die four times which makes up mutually exclusive events will be:
1/6*1/6*1/6*1/6
=(1/6)^4
=1/1296
The answer is B] 1/1296

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

5(x - 2) - 6 = 24

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 6 to both sides:                    5(x - 2) = 30
  2. Divide 5 on both sides:                x - 2 = 6
  3. Add 2 to both sides:                    x = 8

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    5(8 - 2) - 6 = 24
  2. Subtract:                              5(6) - 6 = 24
  3. Multiply:                               30 - 6 = 24
  4. Subtract:                              24 = 24

Here we see that 24 does indeed equal 24.

∴ x = 8 is the solution to the equation.
