Answer:

.15 or 15%

Step-by-step explanation:

There are a total of 4 + 10 + 7 + 5 = 26 marbles in the bucket.

There are a total of 4 red marbles.

The chance of you getting a red marble is 4/26, or 2/13.

2 divided by 13 is .15, and .15 times 100 = 15%.

yulyashka [42]

Answer:

4.10

0.17

Step-by-step explanation:

From the question, we know that

A recent sociological report stated that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.

Also, we're tasked with finding the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.

To find the mean of the sampling distribution, we take the sample mean of the same of that university students as a direct substitute. This then means that the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.

On the other hand, the standard deviation of the sampling distribution of the sample mean alcohol consumption is taken to be the division of the standard deviation of the sample mean. Mathematically, we have

Standard Deviation, S = 1.9101 / √125

Standard Deviation, S = 1.9101 / 11.18

Standard Deviation, S = 0.17

Therefore, the Standard Deviation is 0.17

Acertijo.

Cerrena [4.2K]

La edad de cada uno de los integrantes del acertijo es:

Luisa = 3 años 
Juan = 6 años 
Carmen = 8 años

Cálculo por medio de ecuaciones y el método de igualación.

Haciendo uso de la información brindada en el ejercicio, se procede a formular variables con las cuales se calcularán las ecuaciones, por lo tanto:

X = Edad de Luisa
Y = Edad de Juan
Z = Edad de Carmen

Con el enunciado: "Luisa es 3 años más joven que su hermano Juan" se crea la primera ecuación:

1. Y = X + 3

Con el enunciado: "Su hermana Carmen es 2 años mayor que Juan", se crea la segunda ecuación:

2. Z = Y + 2

Y con el enunciado: "Juan tiene el doble de edad que Luisa", se crea la tercera ecuación:

3. X = $\frac{Y}{2}$

Ahora, utilizando el método de igualación, se reemplaza la tercera ecuación en la primera:

Y = X + 3
Y = ( $\frac{Y}{2}$ ) + 3

Y se procede a sumar:

Y = ( $\frac{Y}{2}$ ) + 3
Y = $\frac{Y+6}{2}$

El dividendo se pasa al otro lado de la igualdad a multiplicar:

2Y = Y + 6

Y la variable "Y" que está sumando, se pasa al otro lado de la igualdad a restar:

2Y - Y = 6
Y = 6

Con el valor de Y (edad de Juan) se calcula X con la tercera ecuación:

X = $\frac{Y}{2}$
X = $\frac{6}{2}$
X = 3

Una vez calculado el valor de X (edad de Luisa), se procede a calcular el valor de Z con la segunda ecuación:

Z = Y + 2
Z = 6 + 2
Z = 8

Por lo tanto, se calcula que la edad de Luisa es 3 años, la edad de Juan es 6 años y la edad de Carmen es 8 años.

The probability that Jane will go to a ballgame (event A) on a Monday is 0.73, and the probability that Kate will go to a ballga

sergiy2304 [10]

Answer:

dependent events since P(A and B) is not equal to P(A) * P(B)

Step-by-step explanation:

According to the Question,

Given, The probability that Jane will go to a ballgame (event A) on a Monday is 0.73, and the probability that Kate will go to a ballgame (event B) the same day is 0.61. The probability that Kate and Jane both go to the ballgame on Monday is 0.52.

Thus, The events A, B and A∩B are:

A - Jane will go to a ballgame on Monday;

B - Kate will go to a ballgame on Monday;

A∩B - Kate and Jane both go to the ballgame on Monday.

P(A)=0.73, P(B)=0.61, P(A∩B)=0.52.

Pr(A)⋅Pr(B) = 0.73⋅0.61 = 0.4453 ≠ 0.52

So, events A and B are dependent events since P(A and B) is not equal to P(A) * P(B)

Can someone help me this problem

konstantin123 [22]

Answer:

A) Yes, m=-3 and b = -3

Step-by-step explanation:

The m is the slope of the line and the b is the y-intercept. We can see that the y-intercept is at -3, so that means D and B are not the answer. This leaves us with A and C. The slope of the line is going down instead of up, meaning that the slope of the line is negative. This means that C is not the answer.

Therefore, the answer is A, m= -3 and b= -3.
