Answer:
- 1.6 days (1 3/5 for simplified form).
Step-by-step explanation:
<u>Given equation:</u>
<u>We know that a box survives 1/5 a day.</u>
<u>It will survive 1 3/5 a day in 8 boxes.</u>
Turn f(x) into y so the equation is y=x+2. Now switch their places so it is x=y+2. Now solve for y. The answer is y=x-2.
Answer:
zonas urbanas => 30 % de la poblacion => 700 millones
poblacion total => 100 % de la poblacion => x => 2333.3 millones
poblacion rural => 70% de la poblacion => x - 700 => 1633.33 millones


Answer:
The probability that five cars will arrive during the next thirty minute interval is 0.0127.
Step-by-step explanation:
Let <em>X</em> = number of cars arriving at Sami Schmitt's Scrub and Shine Car Wash.
The average number of cars arriving in 20 minutes is, 8.
The average number of cars arriving in 1 minute is,
.
The average number of cars arriving in 30 minutes is,
.
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 12.
The probability mass function of <em>X</em> is:

Compute the probability that 5 cars will arrive in 30 minutes as follows:



Thus, the probability that five cars will arrive during the next thirty minute interval is 0.0127.
