I believe this problem has the following table for long distance call:

                                                0-1 minutes                        2-5 minutes                        6+ minutes

Long distance                            170                         120                         10

 

To solve this problem, let us first recall what probability means:

Probability = number of successful event / number of total events

 

In this case, an event is considered to be successful when the long distance call is not 6+ minutes long.  Therefore:

number of successful event = 170 + 120 = 290

 

Now the number of total events is the sum of all number of calls, hence,

number of total events = 170 + 120 + 10

number of total events = 300

 

Probability that the call is not 6+ minutes long is therefore:

Probability = 290 / 300

Probability = 0.9667

or

Probability = 96.67%

What is the y intercept of 2y - 2x = 8
Firdavs [7]

Answer:

Step-by-step explanation:

Write in y = mx + b form

here, b ----> y intercept

2y - 2x = 8

     2y = 2x + 8         {Divide the equation by 2}

       \frac{2y}{2}=\frac{2x}{2}+\frac{8}{2}\\

        y = x + 4

y-intercept = 4

Interest = $45.58, time = 1 year, rate = 2.25%. Find the principal. Round to the nearest hundredth place
Murrr4er [49]

Answer:

<em>$2,025.78 </em>

Step-by-step explanation:

I = Prt ⇒ P = \frac{I}{rt}

2.25% = 0.0225

P = 45.58 ÷ ( 0.0225 × 1 ) ≈ <em>$2,025.78</em>
