Complete question is;

Many states run lotteries to raise money. A website advertises that it knows "how to increase YOUR chances of Winning the Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a "lucky" number to play, but maybe some numbers are luckier than others. Let's use a simulation to see how well this system works. To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number. Any value can be​ picked, but for this​ exercise, pick 1 as the lucky number. What proportion of the time do you​ win?

Answer:

10%

Step-by-step explanation:

We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.

This means the total number of single digits that could possibly be a winning one is 10.

Since we are told that only 1 can be picked, thus;

Probability of winning is; 1/10 = 0.1 or 10%

We''ll use $100 and $200 for the investment amounts.
Using the attached formula,
Years = natural log (200 / 100) / .12
Years = natural log (200 / 100) / .12
Years = 0.69314718056 / .12

PLEASE ANSWER !!

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

y = mx+b

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

y = mx+b

-10=\frac{5}{2}\left(-2\right)+b

-\frac{5}{2}\cdot \:2+b=-10

-5+b=-10

-5+b+5=-10+5

b=-5

And the equation of the line in the slope-intercept form will be:

y = mx+b

putting b = -5 and slope = m = 5/2

y = mx+b

y=\frac{5}{2}x+\left(-5\right)

y=\frac{5}{2}x-5

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

0=\frac{5}{2}x-5

\frac{5}{2}x-5=0

\frac{5}{2}x=5

5x=10

x=2

Therefore, the zeros of the function will be:

  • x = 2
