15 cards left in the deck, and 5 are diamond, to find the probability of the next 2 cards being diamond, one has to find the probability of the 1st card as a diamond, and then multiply it by the probability of the 2nd card being a diamond.
Remember, probability is;
[tex]\frac{favorable-outcomes}{total-outcomes}[/tex]
2. Find probability 1
favorable out comes; diamond = 5
total outcomes; total cards = 15
probability is; [tex]\frac{5}{15}[/tex]
Simplified; [tex]\frac{1}{3}[/tex]
3. Finding probability 2
If the last card drawn was a diamond then the new numbers will be
favorable outcomes; 4
total outcomes; 14
Probability is; [tex]\frac{4}{14}[/tex]
Simplified; [tex]\frac{2}{7}[/tex]
4. Total probability
Now, one has to multiply the first probability by the second probability to find the probability of the event;
[tex]\frac{1}{3} * \frac{2}{7}[/tex]
= [tex]\frac{2}{21}[/tex]
= 0.095238

Step-by-step explanation:
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

a bag contains only red , yellow brown and green marbles
the probabilities of selecting each colour are below
red - 5x
green - 2x
brown - 3x
yellow - 4x
find the probability of selecting a green marble
Answer:
1/7
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur. this is expressed as;
Probability = Expected outcome/Total outcome
From the question, the total number of marbles is the total outcome
Total outcome = 5x + 2x + 3x + 4x
Total outcome = 14x
Since we are to find the probability of selecting a green marble, the expected outcome will be total number of green marbles which is 2x
Pr(selecting green marbles) = 2x/14x
Pr(selecting green marbles) = 1/7
Hence the probability of selecting a green marble is 1/7

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
What is the initial value of the equation shown?
y = −7x − 6
Answer:
[tex]y = -6[/tex]
Step-by-step explanation:
Given
[tex]y = -7x-6[/tex]
Required
Determine the initial value
The initial value of any equation is the point where
[tex]x = 0[/tex]
Substitute 0 for x in [tex]y = -7x-6[/tex]
[tex]y = -7 * 0 - 6[/tex]
[tex]y=0-6[/tex]
[tex]y = -6[/tex]
Hence, the initia; value is -6

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

What is the equation of the line that passes through the point (4,7) and has a slope of -1/4
Answer:
Step-by-step explanation:
since you are given the slope and a point....
use point slope formula y-y1 = m(x-x1)
y - 7 = -1/4 (x - 4)
then get that into the slope intercept form , use the formula y = mx + b as your target
y -7 = -1/4x +1
y = -1/4x +1 +7
y = -1/4x + 8 that's your answer
