Total number of Marbles = 1 + 2 + 5 = 8
P(R) = 1/8
P(G) = 2/8 = 1/4
P(B) = 5/8
R = Event of picking a red marble
G = Event of picking a green marble
B = Event of picking a blue marble
The events are independent, i.e. the outcome of one trial will not affect the probabilities of the outcomes for another trial.
So, we can just multiply the P(B) by P(G) to find the desired overall outcome of the compound events:
5/8 * 1/4 = 5/32

What is the simultanous equation of 2x+y=–5 3x+2y=–8 equation Using the Substitution method​
Artyom0805 [142]

Answer: Equation form: x=-2,y=-1

Point form: (-2, -1)

Step-by-step explanation:

y=-\frac{3x}{2} -4

y=-2x-5

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Solve by Substitution ---> 2x+y=-5 3x+2y=-8

If six times a number is decreased by fourteen, the result is 124. What is the number
denis23 [38]

Answer:

\large\boxed{23}

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is \large\boxed{23}

Hope this helps :)

brilliants [131]

Answer:

Peter will pay:

  • $50 deductible
  • 20% x ($1,060 - $50) = $202
  • total $252

the insurance company will pay:

  • (total counseling cost - deductible) x 80% = ($1,060 - $50) x 80% = $808

The deductible refers to the amount of money an insured has to pay before the health insurance company starts to pay partially or completely for your health treatment. deductibles are commonly used for other types of insurance policies also, including auto insurance.
