A box contains 5 red marbles, 8 green marbles, 4 blue marbles, and 3 yellow marbles. if 2 marbles are randomly selected without replacement, what is the probability that a red marble is selected and then a green marble is selected?
The probability of drawing a red marble first and a green marble second (without replacement) from a box containing 5 red, 8 green, 4 blue, and 3 yellow marbles is 2/19.
Explanation:In the scenario you've described, you would first calculate the probability of selecting a red marble from the box. You have 5 red marbles and a total of 20 marbles (5+8+4+3), so the probability of drawing a red marble first is 5 out of 20, or 1/4.
When you draw a second marble without replacing the first, you have a slightly altered situation - the total number of marbles in the box now comes down to 19. We are interested in the probability of drawing a green marble now. As there are 8 green marbles, probability of drawing a green marble is 8 out of 19, or 8/19.
Probability of a red marble being picked first and then a green marble without replacement is calculated as: P(Red and then Green) = P(Red) * P(Green | Red is already picked). This equals 1/4 * 8/19 = 8/76 = 2/19.

A maze at a county fair is made from 275 bales of hay.the maze at the state fair is made from 4 times as many bales of hay.how many bales of hay are used for the maze at the state fair?
1. State the domain of the rational function. (2 points)
f(x) = thirteen divided by quantity ten minus x.
a) All real numbers except -10 and 10
b) All real numbers except 13
c) All real numbers except 10
d) All real numbers except -13 and 13
2. State the vertical asymptote of the rational function. (2 points)
f(x) = quantity x minus six times quantity x plus six divided by quantity x squared minus nine.
a) x = 6, x = -6
b) x = 3, x = -3
c) x = -6, x = 6
d) None
3. State the horizontal asymptote of the rational function. (2 points)
f(x) = quantity x squared plus four x minus seven divided by quantity x minus seven.
a) None
b) y = -4
c) y = 7
d) y = 6
4. State the horizontal asymptote of the rational function. (2 points)
f(x) = quantity x squared plus eight x minus two divided by quantity x minus two.
a) None
b) y = 1
c) y = -8
d) y = 2
5. Give an example of a rational function that has a horizontal asymptote at y = 0 and a vertical asymptote at
x = 2 and x = 1.
f(x) = 13 / (10-x)
The only x value that would not produce a real number for f(x) is 10, since you
cannot divide a number by zero. Answer is C
2)
F(x)
=(x-6)(x+6)/(x2 - 9)
The vertical asymptotes are x=3 and x=-3. Graph the function on a graphing
calculator to observe the behavior of the function at these points. There is
both a positive and negative vertical asymptote a both x=3 and x=-3. Keep in
mind that the denominator approaches zero at these points, and thus f(x) approaches
either positive or negative infinite, depending on whether the denominator, however small, is a positive or
negative number. Answer is B) 3, -3
3)
F(x) = (x2
+ 4x-7) / (x-7)
Although there is a vertical asymptote as x=7, there is no horizontal asymptote.
This makes sense. As X gets bigger, there is nothing to hold y back from
getting greater and greater. X2 is the dominant term, and it’s only
in the numerator. A) none
4)
(x2 +
8x -2) / (x-2)
This function is very similar in structure to the previous one. Same rules
apply. Dominant term only in the numerator means no horizontal asymptote.
A)None
5)
Our
function approaches 0 as x approaches infinite, and has a vertical asymptote at
x=2 and x=1.
Here’s an easy example: 10 / ((x-2)*(x-1)). At x=2 and x=1, there is both a
positive and negative vertical asymptote. As x approaches infinite, the
numerator is dominated by the denominator, which contains x (actually x2 ),
and thus y approaches zero.
What is (1.3x10^-2)x(0.05) in scientific notation?
To multiply 1.3 x 10^-2 and 0.05 in scientific notation, convert 0.05 to 5 x 10^-2. Multiply 1.3 by 5 to get 6.5, then add the exponents to get 6.5 x 10^-4, which is the final answer in scientific notation.
Explanation:The question asks to calculate the multiplication of 1.3 x 10^-2 and 0.05 and express the result in scientific notation. To solve this arithmetic with numbers in scientific notation, you should multiply the decimal numbers and add the exponents of the ten's powers. The decimal multiplication is 1.3 multiplied by 0.05, which equals 0.065. Since 0.05 is not in scientific notation, it can be written as 5 x 10^-2 to simplify the calculation. Thus, the multiplication becomes (1.3 x 10^-2) x (5 x 10^-2). The next step is to multiply the decimal parts, 1.3 and 5, getting 6.5. The exponents of ten are then added together: -2 + (-2) = -4. The final multiplication gives us 6.5 x 10^-4. However, for true scientific notation, the leading number must be between 1 and 10, so we rewrite 6.5 as 6.5 x 10^0. The final scientific notation is therefore 6.5 x 10^-4.

8. Find the glide reflection image of the black triangle where the translation is (x,y) -> (x,y - 7) and the line of reflection is x = 1.
Am I correct?
Answer:
Option D is correct.
Explanation:
From the given figure,
Labelled the black triangle as A, B and C
The coordinates of triangle ABC are;
A= (2,8) , B= (2,5) and C=(6,5)
To find the glide reflection image of the triangle ABC.
Glide Reflection: It is a composition of transformations.
In glide reflection, a translation is first performed on the figure then it is reflected over a line.
Given: The rule of translation is: [tex](x,y) \rightarrow (x, y-7)[/tex] and line of reflection is x= 1.
Now, apply the rule of translation on black triangle, we get;
[tex]A (2,8) \rightarrow (2, 8-7)[/tex] = A' (2,1)
[tex]B (2,5) \rightarrow (2, 5-7)[/tex] =B' (2,-2)
[tex]C (6,5) \rightarrow (6, 5-7)[/tex] = C' (6,-2)
Next,
Apply the rule of reflection over the line x =1,
i.e, [tex](x,y) \rightarrow (-x+2, y)[/tex]
[tex]A' (2,1) \rightarrow (-2+2, 1)[/tex] =A" (0,1)
[tex]B' (2,-2) \rightarrow (-2+2, -2)[/tex] =B" (0,-2) and
[tex]C' (6,-2) \rightarrow (-6+2, -2)[/tex] =C" (-4,-2)
You can see the graph of Glide reflection as shown below in the attachment.
