Subtract. Use models if needed. (12x + 3) – (2x + 10)

1.)combine like terms: 12-2x=10x 3-10=-7

F(x)=-3x-5 and g(x) =4x-2 find (f-g)(x)

Triss [41]

F(x)=-3x-5 and g(x) =4x-2 find (f-g)(x)

(f-g)(x) = -3x-5 - (4x-2)
(f-g)(x) = -3x -5 -4x + 2
(f-g)(x) = -7x -3

There are 4 red and 6 green marbles in a jar. What is the probability of drawing two green marbles, with replacement?

jeka57 [31]

Answer:

$\frac{9}{25}$

Step-by-step explanation:

Number of red balls = 4

Number of green balls = 6

Total number of balls = 6+4 =10

Probability of drawing a green marble is given as

⇒ $\frac{Number\ of\ green\ balls}{Total\ number\ of\ balls}$

⇒ $\frac{6}{10}$

The ball is replaced after drawing.

Probability of drawing a green ball a second time will be:

⇒ $\frac{Number\ of\ green\ balls}{Total\ number\ of\ balls}$

⇒ $\frac{6}{10}$

Thus, probability of drawing 2 green balls with replacement can be given as:

⇒ (Probability of drawing a green marble) $\times$ (Probability of drawing a green ball a second time)

⇒ $\frac{6}{10}\times\frac{6}{10}$

⇒ $\frac{36}{100}$

Simplifying fraction by dividing numerator and denominator by their GCF.

⇒ $\frac{36\div 4}{100\div 4}$

⇒ $\frac{9}{25}$ (Answer)
