Answer:

25%

OR

(1/4.)

Step-by-step explanation:

So, to get heads twice in a row in two coin tosses it would be 25%. The odds of getting a heads with one coin toss is 50% (1/2.) Every time you do another coin toss the odds are halfed again. So half of 1/2 is 1/4 (think about it as like 50 divided by 2, so 25%.)

<u>Hope this helps and have a nice day! Sorry I'm not great at explaining!</u>

Lashonda purchased a prepaid phone card for $20. Long distance calls cost 8 cents a minute using this card. Lashonda used her ca
Gre4nikov [31]

We know that

• Lashonda purchased a prepaid phone card for $20.

,

• Long-distance calls cost 8 cents a minute.

,

• The remaining credit on her card is $17.12.

This problem can be expressed as

20-0.08x=17.12

Where <em>x</em> is the number of minutes.

We solve the equation for <em>x</em>

\begin{gathered} -0.08x=17.12-20 \\ -0.08x=-2.88 \end{gathered}

Then, we divide by -0.08 the equation

\begin{gathered} \frac{-0.08x}{-0.08}=\frac{-2.88}{-0.08} \\ x=36 \end{gathered}<h2>Therefore, Lashonda's call last 36 minutes.</h2>

Identify an equation in slope intercept form for the line parallel to y= -2/3x+8 that passes through (4, -5)
Evgen [1.6K]

Answer:

3y = -2x -7

Step-by-step explanation:

The equation of the line;

     y = -\frac{2}{3}x + 8

Unknown:

Equation of the line passing through (4, -5);

Solution:

To solve this problem;

    the equation of a line is given as;

        y = mx + c

where x and y are the coordinate

           m is the slope

          c is the intercept

To solve this problem,

  The slope  -\frac{2}{3} if the same as that of the new line since they are parallel;

Equation of the new line;

    x  = 4 and y = -5

     -5 =  -\frac{2}{3} x 4 + c

      -5 = -\frac{8}{3} + c

       c  = -5 + \frac{8}{3}

       c = -\frac{7}{3}

So, the equation of the line is;

    y =  -\frac{2}{3}x - \frac{7}{3}

 or ;

     3y = -2x -7
