Answer:

x = 20

Step-by-step explanation:

6x - 10 = 3x + 50       {Vertically opposite angles}

6x        = 3x + 50 + 10     {Combine like terms}

    6x    = 3x + 60        {Subtract 3x from both sides}

6x -3x  = 60

     3x = 60         {Divide both sides by 3}      

        x = 60/3

x = 20

Stels [109]

Answer:

C) P(E)  = \frac{3}{6}<u></u>

The probability that Mae will roll an odd number

<u></u>P(E)  = \frac{3}{6}<u></u>

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that Mae has a number cube with 6 sides that are numbered 1 through 6.</em>

<em>n(S) = { 1,2,3,4,5,6,} = 6</em>

<em>Let 'E ' be the event of odd numbers</em>

<em>Mae will roll an odd number</em>

<em>n(E) = {1, 3, 5} = 3</em>

<u>Step(ii):-</u>

<u>The probability that Mae will roll an odd number</u>

<u></u>P(E) = \frac{n(E)}{n(S)} = \frac{3}{6}<u></u>

<u></u>P(E)  = \frac{3}{6}<u></u>
