Un estudio que pretendía descubrir la relación entre sufrir heridas de caza y usar ropa anaranjada "de cazador" mostró que de 123 cazadores heridos por ser confundidos con presas, 6 usaban ropa anaranjada (según datos de los Centers for Disease Control). Si un estudio de seguimiento comenzara con la selección aleatoria de cazadores de esta muestra de 123, Calcule la probabilidad de que los primeros dos cazadores seleccionados usaran ropa anaranjada

Probabilidad de que los dos primeros cazadores seleccionados de los 123 cazadores heridos usaran ropa naranja = 0.0020

Probability that the first two selected hunters out of the 123 injured hunters wore orange clothing = 0.0020

Step-by-step explanation:

Hay un total de 6 personas que vestían de naranja de las 123 personas heridas.

Como las dos personas son elegidas sin reemplazo,

Probabilidad de que la primera persona elegida vistiera de naranja = (6/123)

Probabilidad de que la segunda persona elegida también vistiera de naranja = (5/122)

Probabilidad de que los dos primeros cazadores seleccionados de los 123 cazadores heridos usaran ropa naranja = (6/123) × (5/122) = 0.0019992003 = 0.0020 a 4 d.p.

¡¡¡Espero que esto ayude!!!

English Translation

There are a total of 6 people that were wearing orange out of the 123 injured people.

Since the Two people are picked without replacement,

Probability that the first person picked was wearing orange = (6/123)

Probability the second person picked was wearing orange too = (5/122)

Probability that the first two selected hunters out of the 123 injured hunters wore orange clothing = (6/123) × (5/122) = 0.0019992003 = 0.0020 to 4 d.p.

Hope this Helps!!!

3x^3-x^2+6x-9

a) $ 9.50

b) 17

c) y-intercept (0, 12). this is the initial amount of money that joe had prior to playing any game.

d) x-intercept ( 24, 0). this is the number of games that joe will play before he depletes the initial amount of money that he had.

e) slope is -0.5. joe's balance will reduce by 0.5 for every game that he plays.

f)

domain; [0,24]

range; [0,12]

g) x + 2y = 24

step-by-step explanation:

a)

if joe plays 5 games, this will imply that x = 5. substitute x = 5 in the equation and solve for y;

y = -.50x + 12

y = -0.50(5) + 12

y = 9.50

b)

if joe leaves the arcade with $3.50, this will mean that y = 3.50. plug in y = 3.50 in the given equation and solve for x;

y = -.50x + 12

3.50 = -0.50x + 12

0.50x = 12 - 3.50

0.5x = 8.5

x = 17

c)

the function given is   y = -.50x + 12.

the y-intercept is the point where the graph of this function will intersect the y-axis. at this point, the value of x is usually 0. plug in x = 0 in the given equation and determine y;

y = -0.50(0) + 12

y = 12

the y-intercept is thus (0, 12). this is the initial amount of money that joe had prior to playing any game.

d)

the x-intercept refers to the point where the graph of a function intersects with the x-axis. at this point, the value of y is 0. substitute y = 0 in the given equation and solve for x;

0 =   -.50x + 12

0.5x = 12

x = 24

x-intercept ( 24, 0). this is the number of games that joe will play before he depletes the initial amount of money that he had.

e)

the slope of the given equation is -0.5. the equation has been given in slope-intercept form. thus the slope is simply the coefficient of x.

joe's balance will reduce by 0.5 for every game that he plays. this is the interpretation of the slope.

f)

domain is the set of x values for which the function is real and defined. the domain will thus be; [0,24]. this will restrict the balance to only assume positive values.

on the other hand, the range is the set of y values for which a function is real and defined. the range in our case will be [0,12]. joe can have between $0 and $12 balance.

g)

the standard form of the equation of a straight line is;

ax + by = c

where a, b, and c are integers.

our equation is given as;

y = -.50x + 12

re-writing the equation we have;

0.5x + y = 12

divide all through by 0.5;

x + 2y = 24
