The upper quartile for the weights of six puppies, arranged in ascending order and given as 5, 5, 6, 7, 8, 9 ounces, is found by averaging the 4th and 5th points, resulting in 7.5 ounces.
The question seeks to find the upper quartile of the weights of six puppies, which are given in ounces as 8, 5, 7, 5, 6, and 9. To find the upper quartile, step-by-step explanation is necessary. First, we arrange the data in ascending order: 5, 5, 6, 7, 8, 9.
There are 6 data points, so to find the upper quartile (Q3), which divides the top 25% of data from the rest, we identify the data point that falls 3/4th of the way through the dataset. When there are 6 data points, Q3 is calculated by averaging the 4th and 5th data points ((7+8)/2 = 7.5). Therefore, the upper quartile of the data is 7.5 ounces.

Above are two different models of the same rectangle. If the width of the model on the left is 13.75 in, what is the width of the model on the right?
A.
13.25 in
B.
22 in
C.
4.58 in
D.
5 in
The width of the model on the right is 4.58 in.
The scale factor between the two models is 13.75 in / 22 in = 5/8.
The width of the model on the right is 13.75 in * 5/8 = 8.59 in.
Therefore, the answer is C. 4.58 in.

What does it mean to divide figures into known shapes
Dividing figures into known shapes in mathematics helps simplify complex shapes and analyze their properties effectively.
Dividing figures into known shapes involves breaking down complex figures into simpler, identifiable shapes such as squares, rectangles, triangles, or circles.
This process is commonly used in geometry to analyze and understand the properties of irregular shapes by partitioning them into known geometric shapes.
By dividing figures into known shapes, mathematicians can apply specific formulas and principles to calculate areas, perimeters, and other geometric attributes accurately.

Please answer ASAP! I've been stuck on this problem for hours.
Answer:
[tex]V=416\ mm^3[/tex]
Step-by-step explanation:
we know that
The volume of a rectangular prism is given by the formula
[tex]V=LWH[/tex]
we have

At certain times of the year, about 70% of airline flight delays are caused by bad weather. During those times, about 50% of all flights experience bad weather, and about 25% of all flights are delayed.
Given these percentages, if the weather is good, what is the probability that your flight will be delayed?
About 35%
About 20%
About 15%
Answer:
About 15%
Step-by-step explanation:
Since the weather is good, this means that 500 flights are affected because 50% of the flights experience good weather and 50% of the flights experience bad weather.
there will be 75 flights that are delayed due to causes other than bad weather
if you assume that all of the flights that are not caused by bad weather occur in good weather, then the probability would have to be 75 / 500 = .15 = 15%.

I believe is 35%

The population of the town Star City in 2008 was estimated to be 45,000 people with an annual rate of increase of about 2.3%. What is the growth factor of Star City?
Final answer:
The growth factor of Star City is calculated by converting the rate of increase to a decimal and adding it to 1, resulting in a growth factor of 1.023.
Explanation:
The growth factor of Star City with an annual rate of increase of about 2.3% can be calculated as follows:
Identify the percentage of growth as a decimal by dividing the percentage by 100, which would be 2.3/100 = 0.023.
Add this decimal to 1 to find the growth factor: 1 + 0.023 = 1.023.
Therefore, the growth factor of Star City is 1.023.

To determine the sign of the sum of two numbers, we need to consider the signs of the individual numbers (A and B) involved in the sum.
1. If both numbers are positive, their sum is also positive.
2. If both numbers are negative, their sum is also negative.
3. If one number is positive and the other is negative:
- If the positive number has a greater absolute value than the negative number, the sum is positive.
- If the negative number has a greater absolute value than the positive number, the sum is negative.
- If both numbers have the same absolute value, the sum is zero.
The question only presents the expression "B + A" without any information regarding the values or signs of A and B. Therefore, without additional information, it's impossible to determine the sign of their sum. The sum could be positive, negative, or zero depending on the values (and their respective signs) of A and B. Consequently, we cannot choose any of the options above with certainty.
For a complete answer, we would need more details about the values of A and B.
What is the volume of a cube on which each face has a diagonal of 12.8 inches? (round to nearest tenth)
A) 741.2 in3
B) 1,048.6 in3
C) 1,482.9 in3
D) 2,097.2 in3
Final answer:
To find the volume of a cube with each face diagonal of 12.8 inches, calculate the side length using the diagonal length, then find the cube volume using the side length cubed. The volume is approximately 741.2 cubic inches.
Explanation:
Volume of a Cube:
To find the volume of a cube where each face has a diagonal of 12.8 inches, we first need to calculate the length of a side of the cube using the diagonal length. The formula for the diagonal of a face of a cube is √2 times the side length. Thus, side length = diagonal length / √2. Then, we can find the volume of the cube by cubing the side length.
Calculation:
Side length = 12.8 / √2 = 9.04 inchesVolume = [tex](9.04)^3[/tex] = 741.2 cubic inchesIf 6,000 people voted in the election. How many were from 18 to 29 years old?

A regular heptagon has a side length of 13.9 and an apothem of 14.4. Find the area of the regular heptagon. Round your answer to the nearest WHOLE NUMBER. ?
Answer: 701
Step-by-step explanation:
A heptagon has 7 sides, therfore a regular heptagon will have 7 equal sides
n = 7 (number of sides)
s = 13.9 (length of each sides of the heptagon)
r = 14.4 (The apothem)
The area of the regular heptagon can be calculated by:
Area = ½ n × s × r
Area = ½ × 7 × 13.9 × 14.4
Area = 700.56 square units
To the nearest whole number, will be:
Area = 701 square units
