<span><span> When you multiply whole numbers by 10, 100, 1000, and so on (powers of ten), you can simply “tag” as many zeros on the product as there are in the factor 10, 100, 1000 etc.There is a similar shortcut for <span>multiplying decimal numbers </span>by numbers such as 10, 100, and 1000:

Move the decimal point to the right as many places as there are zeros in the factor.</span><span><span><span>10 × 0.49 = 04.9 = 4.9</span><span>    </span></span>Move the decimal point one step to the right (10 has one zero).</span><span><span><span>100 × 2.6<span><span>5 </span> </span>= 265. = 265</span><span>    </span></span>Move the decimal point two steps to the right (100 has two zeros). The number 265. is 265 (as shown above).</span><span><span><span>1000 × 0.370 = 370. = 370</span><span>        </span></span>1000 means we move the point three steps. Write a zero at the end of 0.37 so that the decimal point can “jump over to” that place.</span></span>

Ruby has a bird feeder which is visited by an average of 13 birds every 2 hours during daylight hours. What is the probability t
zalisa [80]

Answer:

62.93%

Step-by-step explanation:

We have to solve it by a Poisson distribution, where:

p (x = n) = e ^ (- l) * l ^ (x) / x!

Where he would come being the number of birds that there would be in 40 minutes, we know that in 2 hours, that is 120 minutes there are 13, therefore in 40 there would be:

l = 13 * 40/120

l = 4,333

Now, we have p (x> 3) and that is equal to:

p (x> 3) = 1 - p (x <= 3)

So, we calculate the probability from 0 to 3:

 p (x = 0) = 2.72 ^ (- 4.33) * 4.33 ^ (0) / 0! = 0.01313

p (x = 1) = 2.72 ^ (- 4.33) * 4.33 ^ (1) / 1! = 0.0568

p (x = 2) = 2.72 ^ (- 4.33) * 4.33 ^ (2) / 2! = 0.12310

p (x = 3) = 2.72 ^ (- 4.33) * 4.33 ^ (3) / 3! = 0.17767

If we add each one:

0.01313 + 0.0568 + 0.12310 + 0.17767 = 0.3707

replacing:

p (x> 3) = 1 - 0.3707

p (x> 3) = 0.6293

Which means that the probability is 62.93%
