Yes You are right 2x+3=15 Subtract 3 from both sides 2x+3-3 = 15-3 2x= 12 Divide both sides by 2 2x/2=12/2 X= 6 I hope that's help !

Solve the following formula for t.<br> A= J(1 + rt)
Lubov Fominskaja [6]

Explic

Pasos para resolver una ecuación linea

A=J(1+rt)

Usa la propiedad distributiva para multiplicar J por 1+rt.

A=J+Jrt

Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo.

J+Jrt=A

Combina todos los términos que contienen J.

(1+rt)J=A

La ecuación está en formato estándar.

(rt+1)J=A

Divide los dos lados por 1+rt.

rt+1(rt+1)J=rt+1A

Al dividir por 1+rt, se deshace la multiplicación por 1+rt.

J=rt+1A

A certain university has 18 vehicles available for use by faculty and staff. Five of these are vans and 13 are cars. On a partic
Reil [10]

Answer:

a

 P(E) = 0.278

b

  P(F |E) = 0.2353

c

P(E and  F) = 0.0654

Step-by-step explanation:

The number of vehicles available is N  =  18

The number of vans is k = 5

The number of cars is n = 13

Generally P(E) is mathematically represented as

P(E) =  \frac{k}{N}

=>    P(E) =  \frac{5}{18}

=>    P(E) = 0.278

Generally P(F| E)  means the probability that the second vehicle assigned is  a van given that the first one selected is a van this mathematically calculated as

      P(F |E) =  \frac{5 -1}{18-1}

        P(F |E) =  \frac{4}{17}

        P(F |E) = 0.2353

Generally  P(F | E) is also mathematically represented as

      P(F | E) = \frac{P(E and F)}{P(E)}

=>   P(E and  F) =P(E) * P(F | E)

=>   P(E and  F) = 0.278  * 0.2353

=>P(E and  F) = 0.0654
