Una poblacion es atacada por una epidemia de gripe sea N(t)= numero de personas enfermas al tiempo t. En dias la epidemia inicio

Lisa [10]

Answer:

<em>Habrán 10175 enfermos a los 15 dias.</em>

Step-by-step explanation:

La tasa de cambio de la población enferma por la epidemia de gripe es:

$N'(t)=120t-3t^2$

Donde t es el tiempo en dias, y se sabe que la epidemia inició en N(0)=50.

Para encontrar la función original que describe el comportamiento de la epidemia, debemos integrar la función:

$N(t)=\int N'(t)dt$

$N(t)=\int (120t-3t^2)dt$

Integrando:

$\displaystyle N(t)=120\frac{t^2}{2}-3\frac{t^3}{3}+C$

Simplificando:

$\displaystyle N(t)=60t^2-t^3+C$

Para determinar el valor de C, usamos la condición inicial N(0)=50:

$\displaystyle 50=60(0)^2-(0)^3+C$

Se tiene que C=50, y la función queda determinada como:

$\displaystyle N(t)=60t^2-t^3+50$

b) El número de enfermos a los t=15 dias se determina substituyendo el valor en la función original:

$\displaystyle N(15)=60(15)^2-(15)^3+50$

Calculando:

$N(15)=13500-3375+50=10175$

Habrán 10175 enfermos a los 15 dias.

There are 20 blue dye 6 red dye and 14 green dye what is the probability of me selecting the green dye

Vesnalui [34]

Answer:

$\boxed {\boxed {\sf \frac{7}{20} \ or \ 35 \% }}$

Step-by-step explanation:

Probability tells us how likely something is to occur. It is found by dividing the favorable outcomes by the total outcomes.

$P=\frac{favorable \ outcomes}{total \ outcomes}$

In this question, a favorable outcome is selecting a green dye. The total outcomes are all the dyes.

Favorable outcomes (green dye): 14
Total outcomes (all dyes): 20 blue+ 6 red+14 green=40

$P(green \ dye)=\frac{14}{40}$

Reduce the fraction. Both the numerator and denominator can be divided by 2.

$P(green \ dye) =\frac{14/2}{40/2}$

$P (green \ dye)=\frac {7}{20}$

This is the probabilty as a fraction. It can also be written as a percent. Divide the fraction, then multiply by 100.

$P(green \ dye)=\frac{7}{20}*100$

$P(green \ dye)=0.35 *100$

$P(green \ dye)=35 =35 \%$

The probablity of selecting a green dye is <u>7/20 or 35%</u>

You are baking batches of cookies for a bake sale. Each batch takes 2.5 cups of flour. You have 18 cups of flour. Can you bake 8

taurus [48]

18 cups ÷ 2.5 cups for each batch = 7.2 batches so its only enough for 7 batches (the .2 isnt really important) not 8
