the length of an arc of a circle is 1/5 of its circumference. if the area of the circle is346.5cm²,find the angle subtended by the arc at the centre of the angle
Answer:
72°
Step-by-step explanation:
From the question,
Area of the circle = πr²
A = πr²................. Equation 1
Where r = radius of the circle.
⇒ r = √(A/π)............. Equation 2
Given: A = 346.5 cm², π = 3.14
r = √(346.5/3.14)
r = √(110.35)
r = 10.5 cm.
Therefore,
circumference of the circle = 2πr = 2×3.14×10.5
circumference = 65.94 m
If the length of the arc(s) is 1/5 of its circumference.
Therefore, length of arc (s) = 13.188
⇒ length of arc/circumference = 13.188/65.94 = 1/5
s/2πr = θ/360
Where θ = angle substends at the center of the circle
1/5 = θ/360
θ = 360/5
θ = 72°
If incomes increase by 58% and the quantity demanded of tennis balls drops by 87% as a result, what is the income elasticity of demand for tennis balls?
The income elasticity of demand for tennis balls is -1.5. The negative sign indicates an inverse relationship between income and the quantity demanded of tennis balls, suggesting that tennis balls are an inferior good.
To calculate the income elasticity of demand, we need to use the formula:
Income Elasticity of Demand = Percentage change in quantity demanded / Percentage change in income
Given that incomes increase by 58% and the quantity demanded of tennis balls drops by 87%, we can plug these values into the formula:
Income Elasticity of Demand = (-87%)/58%
Simplifying the calculation:
Income Elasticity of Demand = -1.5
The income elasticity of demand for tennis balls is -1.5. The negative sign indicates an inverse relationship between income and the quantity demanded of tennis balls, suggesting that tennis balls are an inferior good.

Derive the following result "algebraically" using the properties listed in Theorem 6.2.2. Give a reason for every step that exactly justifies what was done in the step For all sets A.B.and C.(AU C-B=(A-B)u(C-B)
we have proven that (A ∪ C) - B = (A - B) ∪ (C - B) algebraically using the properties of set operations
To prove the equality (A ∪ C) - B = (A - B) ∪ (C - B) for all sets A, B, and C, we'll break down the proof step by step, providing a reason for each step based on set operations and properties.
Step 1: Start with the left-hand side (LHS) of the equation: (A ∪ C) - B.
Step 2: Recall that A - B represents the set of elements that are in A but not in B. Similarly, C - B represents the set of elements that are in C but not in B. Therefore, (A ∪ C) - B can be expanded as (A - B) ∪ (C - B).
Step 3: Distribute the union operator (∪) over the set difference (-).
(A ∪ C) - B = (A - B) ∪ (C - B)
Step 4: Apply the distributive property of set operations.
Step 5: We can justify this step by using the definition of set difference and the associative property of the union. For any set X, (X - B) = X ∩ B', where B' represents the complement of set B. Applying this definition to both (A - B) and (C - B), we can rewrite the equation as:
(A ∩ B') ∪ (C ∩ B').
Step 6: Use the distributive property of intersection (∩) over union (∪).
(A ∩ B') ∪ (C ∩ B') = (A ∪ C) ∩ (B' ∪ B')
Step 7: Apply the complement law, which states that B ∪ B' = Universal set (U). Therefore, B ∪ B' = U.
Step 8: Rewrite the equation as (A ∪ C) ∩ U.
Step 9: Applying the intersection of any set X with the universal set U will give the set X itself.
(A ∪ C) ∩ U = A ∪ C.
Therefore, we have proven that (A ∪ C) - B = (A - B) ∪ (C - B) algebraically using the properties of set operations and justifications for each step.

5 6 7 8 9 + 10 11 12 13 14 15 16 17 18 data a Based on the boxplot above, identify the 5 number summary The Acme Company manufactures widgets. The distribution of widget weights is bell-shaped. The widget weights have a mean of 44 ounces and a standard deviation of 11 ounces. Use the Standard Deviation Rule, also known as the Empirical Rule. Suggestion: sketch the distribution in order to answer these questions. and a) 68% of the widget weights lie between b) What percentage of the widget weights lie between 11 and 55 ounces? S c) What percentage of the widget weights lie above 22?
a. The 68% of the widget weights lie between 33 ounces and 55 ounces.
b. The percentage of widget weights lying between 11 and 55 ounces is approximately 68%.
c. The percentage of widget weights lying above 22 ounces is approximately = 5%.
Based on the given data points: 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, the five-number summary can be identified as follows:
Minimum: 5
First Quartile (Q1): 7
Median (Q2): 11
Third Quartile (Q3): 15
Maximum: 18
Now, let's answer the questions related to the distribution of widget weights using the Empirical Rule:
a) The Empirical Rule states that for a bell-shaped distribution, approximately 68% of the data lies within one standard deviation of the mean. Since the mean is 44 ounces and the standard deviation is 11 ounces, we can say that approximately 68% of the widget weights lie between 44 - 11 = 33 ounces and 44 + 11 = 55 ounces.
b) To determine the percentage of widget weights lying between 11 and 55 ounces, we need to calculate the z-scores for these values. The z-score is calculated using the formula: z = (x - mean) / standard deviation.
For 11 ounces: z1 = (11 - 44) / 11 = -33/11 = -3
For 55 ounces: z2 = (55 - 44) / 11 = 11/11 = 1
Using the Empirical Rule, we know that approximately 68% of the data lies within one standard deviation of the mean. Therefore, the percentage of widget weights lying between 11 and 55 ounces is approximately 68%.
c) To determine the percentage of widget weights lying above 22 ounces, we need to calculate the z-score for 22 ounces: z = (22 - 44) / 11 = -22/11 = -2.
Using the Empirical Rule, we know that approximately 95% of the data lies within two standard deviations of the mean. Therefore, the percentage of widget weights lying above 22 ounces is approximately 100% - 95% = 5%.

A new online music service has a collection of 1,500 songs. It expects to triple the number of songs each year for the next few years. Write an equation representing the relationship, where x is time in years, and y is the number of songs available.
Answer: y = (3^(x-1))*1500
Step-by-step explanation:
We want the relationship
y = f(x)
where y is the number of songs, and x is the number of years.
We know that in the first year, x = 1, the site has 1,500 songs.
The next year, x = 2, the number of songs is tripled, then we will have:
1,500*3 = 4500 songs.
The next year, x = 3, we will have: 3*(3*1500) = (3^2)*1500.
when x = 4, the number is tripled again:
3*(3^2)*1500 = (3^3)*1500
We already can see the pattern, for the year x, the site will have:
y = (3^(x-1))*1500 songs.
This is the equation we are looking for.

The sale price for a jacket that regularly costs $85.00 is now $68.00. With sales tax, a customer pays $73.44. Which THREE statements are correct for this situation?
Answer:
The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Step-by-step explanation:
Here are the options to this question :
A) The sales tax rate is 6%
B) The sales tax rate is 8%.
C. The sale price is 20% less than the regular price
Sales tax rate = (tax paid / discounted selling price) x 100
tax paid = amount customer paid - discounted selling price
$73.44 - $68 = $5.44
($5.44 / $68) x 100 = 8%
The sales tax is 8%
Sales price = (discount / initial price) x 100
discount = $85 - $68 = $17
($17 / 85) x 100 = 20%
Answer:
B.) The Sales Tax Rate is 8%
C.) 85-68/85 = discount rate

The correct answer to 0.125 x 0.08 is 0.01. Dina's calculator provided the correct result.
The rule Dina mentioned about multiplying 125 x 8 and then moving the decimal point 5 places is not applicable in this case. When multiplying decimal numbers, we need to consider the number of decimal places in each factor.
Here's the correct approach to multiply 0.125 x 0.08:
Step 1: Ignore the decimal point and multiply the numbers as if they were whole numbers:
0.125 x 0.08 = 125 x 8
Step 2: Count the total number of decimal places in the original numbers:
0.125 has three decimal places
0.08 has two decimal places
Step 3: Add the number of decimal places from the original numbers:
Three decimal places + two decimal places = five decimal places
Step 4: Place the decimal point in the result by counting five places from the right:
125 x 8 = 1000
Adding the decimal point five places from the right gives us the final answer: 0.01000
Therefore, the correct answer to 0.125 x 0.08 is 0.01. Dina's calculator provided the correct result.

Step-by-step explanation:
It’s not that hard use the formula of the volume of a sphere. And just replace the R with whatever your radius is, if you have a diameter just divide it by 2 to get the radius. Hope this helps
25 points !! Please help me! What’s the volume to this question? Urgent !
Answer:
381 in^3
Step-by-step explanation:
The volume of the green block is V1 = length(width)(height), or
V1 = (16 in)(7 in)(3 in) = 336 in^3, and
the volume of the red triangular prism is V2 = (1/2)(3 in)(5 in)(6 in) =
V2 = 45 in^3
So the total volume is the sum of these two results: 381 in^3
Check if (1,6) is the solution to the system shown below
Answer:
no
Step-by-step explanation:
To determine if (1, 6) is a solution, substitute x = 1, y = 6 into the left side of both equations and if the value obtained equals the right side then it is a solution.
10(1) - 6 = 10 - 6 = 4 ≠ - 6
- 10(1) + 5(6) = - 10 + 30 = 20 ≠ 30
Then (1, 6 ) is not a solution to the system
Fill in the blank The The hypothesis is a statement that the value of a population parameter is equal to some claimed value
It is a fundamental concept in statistical inference and scientific research.
The hypothesis is a statement that the value of a population parameter is equal to some claimed value. A hypothesis serves as a proposed explanation or prediction about the population based on existing knowledge or observations. In statistical hypothesis testing, two types of hypotheses are considered: the null hypothesis (H0) and the alternative hypothesis (Ha). The null hypothesis assumes no significant relationship or difference between variables, while the alternative hypothesis suggests the presence of a significant relationship or difference.
Hypothesis testing involves collecting sample data and performing statistical analysis to evaluate the evidence against the null hypothesis. The goal is to determine whether the data provides enough evidence to reject the null hypothesis in favor of the alternative hypothesis. This process allows researchers to make conclusions about the population based on the available evidence.
Hypothesis testing provides a framework for making objective and informed decisions in various fields of study, such as psychology, biology, economics, and more. It enables researchers to validate or challenge theories, investigate causal relationships, and contribute to the advancement of knowledge in their respective disciplines.
