Answer:
{(Red , Green) ; (Green , Red) ; ((Green , Green)}
Step-by-step explanation:
Here ,we notice that we draw two marbles without replacement.
Then
The possible outcomes are :
• Red then Green
• Green then Red
• Green then Green
NOTE : we can’t have the outcome Red then Red ,because if you pick a red marble and keep it to play with. Then your friend has only the choice of picking a Green marble from the bag.
Therefore,
The sample space is {(Red , Green) ; (Green , Red) ; ((Green , Green)}.

Power is the result of multiplying same number for n number of times. The value of the given expression when simplified is equal to 75.
What is power?Power is the result of multiplying same number for n number of times. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
The given expression can be simplified as shown below.
(5⁴ × 3³) / (5² × 3²)
= (625 × 27) / (25 × 9)
= 16,875 / 225
= 75
Hence, the value of the given expression when simplified is equal to 75.

Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A
How well must Levi score on Exam B in order to do equivalently well as he did on Exam A?The given parameters are:
Exam A
Score = 710
Mean = 700
Standard deviation = 25
Exam B
Mean = 200
Standard deviation = 50
The z-score is calculated as
z = (Score - Mean)/Standard deviation
For exam A, we have
z = (710 - 700)/25
z = 0.4
For exam B, we have
z = (Score - 200)/50
Substitute z = 0.4 in z = (Score - 200)/50
0.4 = (Score - 200)/50
This gives
Score - 200 = 20
Add 200 to both sides
Score = 220
Hence, Levi must score 220 in Exam B in order to do equivalently well as he did in Exam A

x(2x+5) = 3 and 2x²+5x = 3 are equivalent algebraic expression.
Equivalent expressions are those expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s). They are same but looks different.
Given that, x(2x+5) = 3 and 2x²+5x = 3 and we have to conclude how both expressions are related to each other.
Let's procced to solve this.
x(2x+5) = 3 ..............(1)
2x²+5x = 3 ...............(2)
Now, solving equation (1), we get
x(2x+5) = 3 ⇒2x²+5x = 3, which is equation (2)
So, when we solve equation (1), we get equation (2) and vice-versa.
Hence, x(2x+5) = 3 and 2x²+5x = 3 are equivalent algebraic expression.

To meet her goal of riding a total of 28.8 miles, Keilantra needs to ride an average of 6.2 miles.
How to find the average number of miles that she needs to ride each day?Here we know that Keilantra wants to rude her bicycle for a total of 28.8 miles.
We know that she has already ridden 4 miles, so the distance left to meet her goal is:
D = 28.8mi - 4mi = 24.8mi
Now we know that she wants to meet her goal in 4 days, so the average that she needs to ride in each of these 4 days is given by the quotient:
24.8mi/4 = 6.2 mi
To meet her goal, Keilantra needs to ride an average of 6.2 miles.

It was discovered that the pressure in atmospheres (atm), when applied to a balloon, was inversely related to the height in meters, squared root. The pressure was 1.44 atm when the balloon was 25 meters height in the air. What was the pressure like at a 9-meter height?
The pressure is 2.4 atm when the height is 9m.
Inversely proportion means when one variable is directly proportional to the reciprocal of the other, there is an inverse fluctuation between the two variables. In other words, the two variables' product has a fixed value. Therefore, as one variable rises, the other falls.
Here, We take pressure of atmosphere as P and the height of the balloon as H.
Given that, The pressure of atmosphere was inversely proportional to the square root of the height.
We write this as [tex]P[/tex]∝[tex]\frac{1}{\sqrt{H} }[/tex].
Taking constant of the proportionality as k.
[tex]P[/tex]=[tex]\frac{k}{\sqrt{H} }[/tex].
We have, The pressure was 1.44 atm when the balloon was 25 meters height in the air.
P=1.44 and H=25
[tex]1.44=\frac{k}{\sqrt{25} }[/tex].
[tex]1.44=\frac{k}{5}[/tex]
[tex]k=5\times1.44[/tex]

slope intercept form of -5/6x+4
The slope of equation y = -5/6 x + 4 is -5/6 and the slope-intercept form of -5/6x+4 is y = -5/6 x + 4
The slope of a function y = f(x) is given by a formula
slope = y2-y1 / x2- x1
where ( x1 , y1) and (x2, y2) are coordinates of any two points on the line of graph representing y = f(x)
Or we can simply use the slope-intercept form
y = mx+ c
where m is the slope of the given equation and c is the constant
so, in the given equation y = -5/6 x + 4
slope of the equation is -5/6
Hence, The slope of equation y = -5/6 x + 4 simply is -5/6 and the slope intercept form of -5/6x+4 is y = -5/6 x + 4
When you know the slope of the line to be investigated and the point given is also the y intercept, you can utilize the slope intercept formula y = mx + b. (0, b). The y value of the y intercept point is represented by b in the formula.

Because the triangle BAC is an isosoles angle BCA and ABC must be the same so 48
We can now use the angle on a straight line rule to figure out angle DBA 180-48=132
We know that triangle DBA is an isosoles trianlge so and x and DAB must be the same and both be x, and we know that angles in a triangle add up to 180 so the equation can be written as:

The ratio 3/4 can be represented as:
m : n = 3 : 1
So, the coordinate of point E is
E = 1/(m + n) * (mx2 + nx1, my2 + ny1)
So, we have:
E = 1/(3 + 1) * (3 * -3 + 1 * 1, 3 * -4 + 1 * 6)
