Mr jones is losing 20 percent of his hair each year if he currently has 1546 hairs on about how many hair will he have left afte
dedylja [7]
I seemed to have forgot the formula for how to solve such a question so what I did was take my trust calculator, place the number he'd start with each year, multiply it by 0.2 or the 20%, and subtract that from the number he started with to get how many hairs he would start with in the next year. Then rinse-repeat until I got to 10 years.

Example:

1st year would be 1546 - (1546 x 0.2) = 1546 - 309.2 = 1236.8 hairs to start the 2nd year.

At the end of year 10, my calculation had Mr. Jones left with 166.000486 or ≈166 hairs left on his head. I'd suggest Mr. Jones invested in a women's razor; I've heard their blades are better for shaving yourself bald.

Suppose the number of hits a webpage receives follows a Poisson distribution. The average number of hits per minute is 2.4. What
REY [17]

Answer:

The probability that the page will get at least one hit during any given minute is 0.9093.

Step-by-step explanation:

Let <em>X</em> = number of hits a web page receives per minute.

The random variable <em>X</em> follows a Poisson distribution with parameter,

<em>λ</em> = 2.4.

The probability function of a Poisson distribution is:

P(X=x)=\frac{e^{-\lambda}\lambda^{x}}{x!};\ x=0,1,2,...

Compute the probability that the page will get at least one hit during any given minute as follows:

P (X ≥ 1) = 1 - P (X < 1)

             = 1 - P (X = 0)

             =1-\frac{e^{-2.4}(2.4)^{0}}{0!}\\=1-\frac{0.09072\times1}{1} \\=1-0.09072\\=0.90928\\\approx0.9093

Thus, the probability that the page will get at least one hit during any given minute is 0.9093.
