A bag contains 4 g r e e n marbles, 8 b l a c k marbles, and 7 b l u e marbles. If a marble is drawn from the bag, replaced, and another marble is drawn, what is the probability of drawing first a g r e e n marble and then a b l u e marble
Answer:
[tex]P(Green\ and\ Blue) = 0.0776[/tex]
Step-by-step explanation:
Given
[tex]Green = 4[/tex]
[tex]Black = 8[/tex]
[tex]Blue=7[/tex]
Required
Determine the probability of selecting green then blue marble
This probability is represented as:
[tex]P(Green\ and\ Blue)[/tex]
And it is calculated using:
[tex]P(Green\ and\ Blue) = P(Green) * P(Blue)[/tex]
[tex]P(Green\ and\ Blue) = \frac{n(Green)}{Total} * \frac{n(Blue)}{Total}[/tex]
Total marble is:
[tex]Total = 4 + 8 + 7[/tex]
[tex]Total = 19[/tex]
So, we have:
[tex]P(Green\ and\ Blue) = \frac{4}{19} * \frac{7}{19}[/tex]
[tex]P(Green\ and\ Blue) = \frac{4*7}{19*19}[/tex]
[tex]P(Green\ and\ Blue) = \frac{28}{361}[/tex]
[tex]P(Green\ and\ Blue) = 0.0776[/tex] -- approximated
Hence, the required probability is approximately 0.0776

Which equation represents the rectangular form of r = 8?
Answer:
x^2 + y^2 = 64
Step-by-step explanation:
EDGE 2020
The equation that represents the rectangular form of r = 8 is x² + y² = 64
What is rectangular form?Rectangular form, is where a complex number is denoted by its respective horizontal and vertical components.
According to the given problem,
x=rcosθ
y=rsinθ
substituting we have
x=8cosθ
y=8sinθ
Squaring and adding we obtain the
circle's origin centered equation,
x² + y² = 64
Hence, we can conclude, the equation x² + y² = 64, represents the rectangular form of r = 8.

Set the two equations equal
8 + 1.25x = 10+.75x
Subtract .75x from each side
8 + 1.25x-.75x = 10+.75x-.75x
8 + .5x = 10
Subtract 8 from each side
8-8 + .5x=10-8
.5x =2
Divide each side by .5
.5x/.5 = 2/.5
x = 4
