To find the probability of selecting a green gum ball followed by a yellow gum ball, we first calculate the total number of gum balls and then determine the number of ways to select a green gum ball followed by a yellow gum ball.
[tex]\text{Total number of gum balls} = 9 (red) + 5 (green) + 8 (yellow) + 8 (blue) = 30[/tex]
Number of ways to select a green gum ball followed by a yellow gum ball:
There are [tex]5[/tex] green gum balls and [tex]8[/tex] yellow gum balls.
Therefore, the number of ways to select a green gum ball followed by a yellow gum ball is [tex]\(5 \times 8 = 40\)[/tex]
The probability of selecting a green gum ball followed by a yellow gum ball is the number of ways to select them divided by the total number of gum balls:
[tex]\[ P(\text{green, then yellow}) = \frac{40}{30 \times 29} \][/tex]
[tex]\[ P(\text{green, then yellow}) = \frac{40}{870} \][/tex]

The results of a survey indicate that between 76% and 84% of the season ticket holders are satisfied with their seat locations.
What is the survey’s margin of error?
Enter your answer in the box. ± ___ %
The answer goes on the underscores
Final answer:
The margin of error for the survey, given a range between 76% and 84% satisfaction for seat locations, is calculated to be ±4%.
Explanation:
The margin of error in a survey indicates how much the survey results might differ from the actual opinions of the total population.
In this case, the survey indicates a satisfaction range between 76% and 84% for seat locations among season ticket holders.
The margin of error is half of the width of the range, which is the difference between the upper and lower percentage bounds of the confidence interval divided by two.
To calculate the margin of error, subtract the lower percentage (76%) from the upper percentage (84%) and then divide by 2. That is, (84 - 76) / 2 = 8 / 2 = 4.
Thus, the margin of error for the survey is ±4%.

Jenny has a rope that is 7 1/2 She wants to cut it into pieces that are 3/4of a foot long.
How many pieces of rope will Jenny get?
5 5/8
8
10
1/10
Jenny will get 5 pieces of rope.
What is the ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
To find out how many pieces of rope Jenny will get, we need to divide the total length of the rope by the length of each piece:
Total length of the rope = 7 1/2 = 15/2
Length of each piece = 3/4
Number of pieces = (15/2) ÷ (3/4)
We can simplify this expression by dividing the numerator and denominator of the left-hand side by 2:
Number of pieces = (15/2) × (4/3)
Number of pieces = 30/6
Number of pieces = 5
Therefore, Jenny will get 5 pieces of rope.

The original vertices of a quadrilateral are (-2,3), (4,6), (4,2), and (3, -2). After a transformation, the new coordinates are (-1,1.5), (2,3),(2,1), and (1.5,-1). Are the two images similar? Justify your answer.
A) no; The transformation is not rigid; therefore, the quadrilaterals are not similar.
B) no; The transformation is a translation which only results in the size of the quadrilaterals being preserved.
C) yes; This is a rigid transformation which preserves angle measurement and size of the original quadrilateral.
D) yes; The transformation is a dilation which results in similar quadrilaterals by preserving angle measurements.
The answer would be D) yes; The transformation is a dilation that results in similar quadrilaterals by preserving angle measurements.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
The original vertices of a quadrilateral are (-2,3), (4,6), (4,2), and (3, -2).
After a transformation, the new coordinates are (-1,1.5), (2,3),(2,1), and (1.5,-1).
As we know that dilation is a process for creating similar figures by changing the size.
This means that the two images are similar, as they have the same shape and size, despite having different positions and orientations in the coordinate plane.
Hence, the given transformation is a dilation that results in similar quadrilaterals by preserving angle measurements.

How to find the third side of a triangle if two sides are known?
Final answer:
To find the third side of a triangle when two sides are known, you can use the Triangle Inequality Theorem or the Law of Cosines.
Explanation:
To find the third side of a triangle when two sides are known, you can use the Triangle Inequality Theorem or the Law of Cosines.
Triangle Inequality Theorem:
Take the two known sides of the triangle.
Add the lengths of the two sides together.
Subtract the sum from the total perimeter of the triangle.
Law of Cosines:
Label the two known sides as 'a' and 'b', and the angle between them as 'C'.
Use the formula c² = a² + b² - 2abcos(C) to find the square of the third side.
Take the square root of the result to find the length of the third side.
What is the lateral area of the prism? Assume the figure is resting on its base.
Suppose y varies directly with x and y=-25 when x=5. find y when x=3
Final answer:
To solve for y when x = 3, we first determined the constant of proportionality (k) using the given values (y = -25 when x = 5). With k found to be -5, we then calculated y for x = 3 to find that y = -15.
Explanation:
The question asks us to find the value of y when x = 3 given that y varies directly with x and that y = -25 when x = 5. Because y is directly proportional to x, we can write the relationship as y = kx, where k is the constant of proportionality.
First, we solve for k:
Set up the equation based on the given information: y = kx
Substitute the known values: -25 = k(5)
Solve for k: k = -25 / 5 = -5.
Now that we have found k, we can use it to find y when x = 3:
Use the determined value of k: y = -5(3)
Multiply to find y: y = -15.
Therefore, when x = 3, y is -15.
