During his vacation, Dalyn rents a small boat from a rental service that charges a flat fee of $30 plus $10 per hour (including

ratio 5:2

105, ___

5x = 105 → x = 21

2x = ____ → 2(21) = 42

Result: 42°

Response:

b

Detailed explanation:

because that's the solution jfjfjdkdkdkdkdjdmf

The numerical variables in this scenario include:

A. Speed

D. GForce

E. Height

G. Duration

H. Numinversions

J. Length

In detail:

A method to distinguish quantitative from qualitative variables is assessing if mathematical calculations on these variables are relevant.

When it is applicable, it indicates a quantitative variable.

For instance, even though binary variables can be expressed as 0 and 1, they are still considered qualitative variables.

The numerical variables in this case are:

A. Speed

D. GForce

E. Height

G. Duration

H. Numinversions

J. Length

They will all be expressed in numerical terms where mathematical operations are meaningful.

To solve this problem, you'll need to create two equations:
x + y = 155 (total packages)
3x + 8y = 815 (total weight)
Next, multiply the first equation by 3: 3x + 3y = 465.
Then, subtract the first equation from the second to find that 5y = 350, which means y = 70. Thus, there are 70 packages that weigh 8 pounds. 

Respuesta:

P = 2/7 = 0.2857 o 28.57%

Explicación paso a paso:

En primer lugar, sabemos que hay 15 bolas y necesitamos identificar cuáles son pares y superiores a 10.

Por lo tanto, debemos calcular inicialmente la probabilidad de que el número obtenido sea par.

Los números pares son 2, 4, 6, 8, 10, 12, 14

Contamos 7 números de 15 ---> P(B) = 7/15

De esos números, solo dos son mayores a 10, que son 12 y 14, así que: P(A|B) = 2/15

Para encontrar la probabilidad de obtener un número par mayor que 10:

P(A/B) = P(A|B) / P(B)

P(A/B) = 2/15 / 7/15 = 2/7 = 0.2857

Para calcular el porcentaje: 0.2857 * 100 = 28.57%.
