The radius of a circle is 4 inches. What is the area of a sector bounded by 180° arc?
Answer:
Step-by-step explanation:
If you're asking for the area of the sector, it's the central angle of 360, times the area of the circle, for example, if the central angle is 60, and the two radiuses forming it are 20 inches, you would divide 60 by 360 to get 1/6.
The requried area of a sector bounded by a 180° arc is 8π square inches.
What is an area of the sector?The area of a sector is a portion of the circle enclosed by two radii and an arc and is given by the formula A = (θ/360)πr², where θ is the angle in degrees and r is the radius of the circle.
Here,
The area of a sector bounded by a 180° arc in a circle with a radius of 4 inches can be found using the formula;
A = (θ/360)πr²
Where θ is the angle in degrees and r is the radius.
Since the angle is 180°, we have:
A = (180/360)π(4²) = 8π square inches.
Thus, the area of a sector bounded by a 180° arc is 8π square inches.

(04.03) The table shows the ratio of caramel corn to hot pepper corn in a bag. What is the constant of proportionality?
Hot Pepper Corn Caramel Corn
5 8
10 16
15 24
3
8
1.6
0.625
Answer:
0.625
Step-by-step explanation:
To solve the problem, we merely just divide the rates by each other. Ratios are just the fractions of two terms, after all.
Therefore, the answer would be 5/8, or 0.625.
To verify, we can use the other values given in your question.
10/16 is also an answer, but when you simplify, you get 5/8, which gives the same answer- 0.625.
You can do the same with the other ratios given.
15/24 simplified is 5/8, which, once again, is 0.625.
Thus, I can say with certainty that the answer is 0.625.

The manager of a symphony in a large city wants to investigate music preferences for adults and students in the city. Let pA represent the population proportion of adults who live in the city who prefer pop music. Let pS represent the population proportion of students who live in the city who prefer pop music. Random samples of 200 adults from the city and 200 students from the city will be selected. Which of the following is the best interpretation of P(pˆA−pˆS>0)≈0.022 ?
Answer:
Answer E
Step-by-step explanation
The statement gives a probability of approximately 0.022 for the difference in sample proportions, pˆA−pˆS, being greater than 0.
The interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".
Given :
pA is the population proportion of adults.pS is the population proportion of students.The total number of adults is 200 and the total number of students is also 200.The following steps can be used in order to determine the best interpretation of the given expression:
Step 1 - According to the given data, pA is the population proportion of adults who live in the city who prefer pop music.
Step 2 - Also given that pS is the population proportion of students who live in the city who prefer pop music.
Step 3 - So, the interpretation of the given expression is "the difference between the population proportion of adults and the population proportion of students who prefer pop music is approximately 0.022".
Therefore, the correct option is A).

find the additive inverse of-9x+3
Answer:
9x − 3
Step-by-step explanation:
−9x + 3 = −1(−9x + 3) Multiply the expression by −1.
−1(−9x) + −1(3) Distributive Property
9x − 3 Simplify.
The additive inverse of the given expression is 9x-3.
The given expression is -9x+3.
What is additive inverse?The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.
The additive inverse of the expression is -(expression).
Now, -(-9x+3)
= 9x-3
Therefore, the additive inverse of the given expression is 9x-3.
