k = A'C'/ACk = 6/24 = 1/4A triangle has two sides of lengths 6 and 9. What value could the length of
the third side be? Check all that apply.
OA. 7
B. 2
C. 4
OD. 15
□E. 10
O F. 12
SUBMIT
B. 2 and OD. 15 are not possible lengths for the third side of the triangle.
To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Given that two sides have lengths 6 and 9, we can analyze the possibilities:
6 + 9 > x
x > 15 - The sum of the two known sides is greater than any possible third side.
6 + x > 9
x > 3 - The length of the unknown side must be greater than the difference between the two known sides.
9 + x > 6
x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.
Based on the analysis, the possible values for the length of the third side are:
A. 7
C. 4
□E. 10
O F. 12
B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

A.The value is a parameter because the governors of all 50 area of a country nothingare a population.
B.The value is a statistic because the governors of all 50 area of a country nothingare a population.
C.The value is a statistic because the governors of all 50 area of a country nothingare a sample.
D. The value is a parameter because the governors of all 50 area of a country nothingare a sample.
The election comma Modifying 18 % with underline of the governors of all 50 areas of a country were female.
Based on this, thr correct answer is A. The value is a parameter because the governors of all 50 area of a country nothing are a population.
Parameters definitionParameter is a term that comes from the Greek, namely para which means beside, and metron which means size. In general, a parameter is any characteristic that can help in defining and classifying a particular system (an event, project, object, situation, etc.). This means, parameters are system elements that are useful or critical, when identifying a system, or when evaluating its performance, status, condition, etc.
Parameter is a term that refers to a size or benchmark. parameter is the size of the entire population in the study which must be estimated from that contained in the sample. Parameter is a benchmark for a value with conditions that are expected to be achieved and can be one of the conditions for achieving goals.
As previously mentioned, parameters have more specific meanings in various disciplines, such as mathematics, computer programming, engineering, statistics, logic, linguistics, to electronic music composition. Apart from being used in technical uses, there are also extended uses, especially in non-scientific contexts, where the term is used to mean a characteristic or limitation, as in the phrases 'test parameters' or 'game parameters'.

Tory bought a bike for $149. he paid a finance charge of $45 and paid over eight months.
what is the approximate apr for his purchase?
0 47.0%
o 45.3%
40.1%
38.2%
To calculate the approximate APR for Tory's bike purchase, we need to use the formula for simple interest:
Interest = Principal x Rate x Time
Here, the principal is $149 and the finance charge is $45, making the total amount financed $194. Tory paid over eight months, so the time is 8/12 or 0.67 years.
Using the formula, we can solve for the rate:
$45 = $194 x Rate x 0.67
Rate = $45 / ($194 x 0.67)
Rate = 0.357 or 35.7%
Therefore, the approximate APR for Tory's bike purchase is 35.7%.
None of the answer choices provided match the exact percentage, but the closest is 38.2%, so that would be the best choice.

Step-by-step explanation:
Patrick is riding his bike on a rectangular path around his city.
There is a rest area at each of the path's four corners.
• The city map shows the corners marked with coordinates of (2, 2), (1, 2), (1, -2), and (-2,-2).
Each unit represents 2.5 miles.
What is the perimeter of the path, in miles?
With the given coordinates it doesn't form a rectangle the correct set of the coordinates should be (2, 2), (1, 2), (1, -2), and (2,-2).
Answer:
The perimeter of the given rectangle that is formed by the given coordinates is 30miles.
Step-by-step explanation:
We are given the Rectangular coordinates such as
(2,2) , (1,2) ,(1,-2) (2,-2)
we will mark these point on the cartesian planes to understand the rectangle
We can apply the distance formula or we can just look on the cartesian plane to simply get the distance between two points
we get
[(2,2) ,(1,2) ] and [(1,-2) ,(2,-2) ] are two units apart each pair as they are parallel so our width is
W = 2 units
similarly
we now need the length
(1,2) and (1,-2) are four units apart
so our length will be four units
L= 4 units
we need the perimeter
Perimeter of the rectangle = 2( L+W)
= 2( 2 + 4)
= 2* 6 = 12units
Now we are given that 1 unit is equal to 2.5 miles so 12 units will be
= 12* 2.5 = 30 miles
Therefore The perimeter of the given rectangle that is formed by the given coordinates is 30miles.
in san deigo the ratio of cloudy days to sunny days is 3:7 what percentage of the days are sunny
70% of the days in San Diego are sunny.
In San Diego, the ratio of cloudy days to sunny days is 3:7.
To find the percentage of sunny days, we need to determine the proportion of sunny days out of the total number of days.
Let's assume that there are a total of 10 days.
Based on the ratio, we can say that 3 out of 10 days are cloudy, and 7 out of 10 days are sunny.
To calculate the percentage of sunny days, we divide the number of sunny days (7) by the total number of days (10) and multiply by 100.
So, \((\frac{7}{10} )\times 100= 70\%\).
Therefore, approximately 70% of the days in San Diego are sunny.

Work out the value of 5 to the power of a if it equal 1/125
Answer:
a = -3
Step-by-step explanation:
Step 1: Since we're told that 5 to the power of a = 1/125, we can use the following equation to solve for a:
5^a = 1/125
Step 2: Take the log of both sides
log(5^a) = log(1/125)
Step 3: According to the power rule of logs, we can bring a down and multiply it by log(5):
a * log(5) = log (1/125)
Step 4: Divide both sides by log(5) to solve for a:
(a * log(5) = log(1/125)) / log(5)
a = -3
Optional 5: We can check our answer by plugging in -3 for a and seeing if we get 1/125 when completing the operation:
5^-3 = 1/125
1/(5^3) = 1/125 (rule of exponents states that a negative exponent creates a fraction with 1 as the numerator and the base (5) and exponent (-3 becoming 3) as the denominator
1/125 = 1/125

Use the given data to find the minimum sample size required to estimate the population proportion.
Margin of error: 0.04; confidence level : 99%; from a prior study, p hat is estimated by 0.07.
To find the minimum sample size required to estimate the population proportion, we'll use the following formula:
n = (Z^2 * p_hat * (1 - p_hat)) / E^2
where:
n = minimum sample size
Z = Z-score, which corresponds to the desired confidence level (99% in this case)
p_hat = estimated population proportion (0.07)
E = margin of error (0.04)
First, we need to find the Z-score for a 99% confidence level. You can find this value using a standard normal distribution table or a calculator. For a 99% confidence level, the Z-score is approximately 2.576.
Now, we can plug the values into the formula:
n = (2.576^2 * 0.07 * (1 - 0.07)) / 0.04^2
n = (6.635776 * 0.07 * 0.93) / 0.0016
n = 0.464507328 / 0.0016
n = 290.316955
Since we cannot have a fraction of a participant, we round up to the nearest whole number to ensure the desired margin of error and confidence level are met.
Minimum sample size (n) = 291

b. the average amount of electricity consumed
c. the amount of paint used in repainting in a building
d. the average weight of female athletes
Among the given options, the only variable that is a discrete random variable is a) the number of patients in a hospital.
a. the number of patients in a hospital
A discrete random variable is a variable that can only take on a finite or countably infinite set of distinct values. In this case, the number of patients in a hospital can only be whole numbers (e.g., 0, 1, 2, 3, etc.), which is a countable set of values. Therefore, it is a discrete random variable.
b. the average amount of electricity consumed
The average amount of electricity consumed is not a discrete random variable but a continuous random variable. It can take on any real number value within a certain range, and it is not restricted to specific distinct values.
c. the amount of paint used in repainting a building
The amount of paint used in repainting a building can be measured in continuous quantities (e.g., liters or gallons). It is not restricted to specific distinct values, and therefore, it is not a discrete random variable.
d. the average weight of female athletes
Similar to the average amount of electricity consumed, the average weight of female athletes is not a discrete random variable but a continuous random variable. It can take on any real number value within a certain range and is not restricted to specific distinct values.

What is the name of the segment inside the large triangle?
1. Perpendicular bisector
2.Midsegment
3.Angle Bisector
4.Median
The name of the segment inside the large triangle is called the: 3. angle bisector.
What is an Angle Bisector?The word "bisect" means to divide into two equal halves. Therefore, an angle bisector can be defined as a line segment that divides the an angle in a triangle into two parts that are of the same angle measure.
The image shows a triangle which has a segment that divides a vertex angle into equal parts. Thus, the segment can be named as an angle bisector.
A perpendicular bisector divides a segment into two equal halves at right angle, while a midsegment joins the middle points of two sides of a triangle. The median also, is a segment that joins a vertex of a triangle to the midpoint of the side that is opposite the angle.
Therefore, we can state that the name of the segment is: 3. angle bisector.

What is the factorization of the polynomial below
Answer:
2(x+6)²
Step-by-step explanation:
Answer:
(x+6)(2x+12)
Step-by-step explanation:
First, because a>1, you have to multiply c by a, which gives you 144. Now, you need to find factors of 144 that add to 24. Those factors would be 12 and 12. Now, you expand the equation:
2x^2+12x+12x+72
Now, you factor the first two terms and last two terms:
The GCF of 2x and 12x is 2x, so divide by 2x
2x(x+6)
The GCF of 12 and 72 is 12, so divide by 12
12(x+6)
The two parenthesis match, so they are one term. All that's left to do is factor the terms outside the parenthesis, and you get:
(x+6)(2x+12)

Write your question here (Keep it simple and clear to get the best answer)4x³-5x is it odd or even function
Answer:
odd
Step-by-step explanation:
To determine if odd/ even
• If f(x) = f(- x) then it is even
• If f(- x) = - f(x) then it is odd
Given
f(x) = 4x³ - 5x , then
f(- x) = 4(- x)³ - 5(- x) = - 4x³ + 5x
Since f(x) ≠ f(- x) then it is not even
- f(x) = - (4x³ - 5x) = - 4x³ + 5x
Since f(- x) = - f(x) , then 4x³ - 5x is odd
