Un bosque de 2 km2 está formado por hayas y pinos. Las hayas ocupan 380.000 m2 ¿Cuántos metros cuadrados ocupan los pinos?
1 answer:
Answer:
Los pinos ocupan o <em>1 millón seiscientos veinte mil metros cuadrados</em>.
Step-by-step explanation:
Una manera de resolver este problema es la siguiente:
En palabras, , o <em>dos kilómetros cuadrados</em> son iguales a <em>2 millones de metros cuadrados</em>.
Sabemos que:
- Estos
de bosque lo ocupan hayas y pinos, y, adicionalmente,
- Las hayas ocupan
.
De esta manera, <em>la parte que ocupan los pinos es el total del bosque menos el área ocupada por las hayas</em>. Por lo tanto, el área ocupada por los pinos es:
¿Cuántos metros cuadrados ocupan los pinos?
Los pinos ocupan, entonces, o <em>1 millón seiscientos veinte mil metros cuadrados</em>.

Using the binomial distribution, it is found that there is a 0.056 = 5.6% probability that more than 7 will make a purchase.
<h3>What is the binomial distribution formula?</h3>The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- There are 12 customers, hence n = 12.
- The probability of any of them making a purchase is of p = 0.4.
The probability that more than 7 will make a purchase is given by:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12).
Hence:
Then:
P(X > 7) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) = 0.042 + 0.012 + 0.02 + 0 + 0 = 0.056.
0.056 = 5.6% probability that more than 7 will make a purchase.

let's firstly convert the decimal to a fraction, namely a rational.
so we have one decimal, thus let's use 1 zero at the denominator and lose the dot on the numerator.
so then, what rationals are between -8/5 and +8/5? well, a huge amount hmmm let's pick two.
