Answer:
- π is the area of a circle of radius 1
- π is the circumference of a circle of diameter 1
- π is the constant of proportionality relating the diameter of a circle to its circumference
Step-by-step explanation:
Area of a circle = πr² or πd²/4
Circumference of a circle = 2πr or πd
r is the radius
d is the diameter
If radius = 1
Area = π(1)²
Area = π
hence π is the area of a circle of radius 1 is CORRECT
Given d = 1
Area = πd²/4
Area = π(1)²/4
Area = π/4
Hence π is the area of a circle of diameter 1 is INCORRECT
For the circumference;
C = 2πr or πd
If r =1
C = 2π(1)
C = 2π
Hence π is the circumference of a circle of radius 1 is INCORRECT
Also if d = 1;
C = πd
C = π(1)
C = π
hence π is the circumference of a circle of diameter 1 is CORRECT
Since C = πd, then π is the constant of proportionality relating the diameter of a circle to its circumference is CORRECT

The Social Security Administration increased the taxable wage base from $127,400 to $128,400. The 6.2% tax rate is unchanged. Joe
Burns earned over $130,000 each of the past two years.
a. What is the percent increase in the base? (Round your answer to the nearest hundredth percent.)
Percent increase
b. What is Joe's increase in Social Security tax for the new year?
Increase in social security tax?
Answer:
0.7849 %
$62
Step-by-step explanation:
Given that:
Initial taxable wage = $127,400
New taxable wage = $128,400
Amount earned each of the past two years = $130,000
The percentage increase :
((new wage - initial wage) / initial wage) * 100%
((128400 - 127400) / 127400) * 100%
0.0078492* 100%
= 0.7849 %
Increase in social security tax for the new year:
Increase in wage * social security tax rate
(128400 - 127400) * 6.2%
1000 * 6.2%
= $62

Find the common difference of the arithmetic sequence.
4, 3 2/3, 3 1/3, 3
Answer:
1/3 is the awnser
Step-by-step explanation:
1/3 is the common difference of the given arithmetic sequence.
What is common difference?The common difference is the difference that exists in between each pair of terms that follow one another's sequence.
The given arithmetic sequence is,
4, 3²/₃, 3¹/3, 3 .......
To find common difference,
The difference between first two terms = 4 - 3²/₃ = 4-11/3 = 1/3
The difference between send and third term = 3²/₃-3¹/3 = 11/3 - 10/3 = 1/3
The common difference of the sequence is 1/3.

Drag numbers to complete the prime factorization of 84. Numbers may be used once, more than once, or not at all
The prime factorization of the number 84 is as follows:
84 = 7 × 1284 = 3 × 4 × 784 = 2 × 2 × 3 × 7What is prime factorization?The technique of expressing all numbers as the product of primes is known as prime factorization. So, let's take something like the number 20 as an example. That can be divided into two components. "Well, that's 4 times 5," we can respond. Observe that 5 is a prime number.Finding the prime numbers that multiply to create the original number is known as "prime factorization."So, finding the numbers using prime factorization:
84:
84 = 7 × 1284 = 3 × 4 × 784 = 2 × 2 × 3 × 7Therefore, the prime factorization of the number 84 is as follows:

Suppose a sales manager wants to compare different sales promotions. He chooses 5 different promotions and samples 10 random stores for each different promotion. The F value is 3.4. Using JMP, find the correct p-value.
Answer:
The correct p-value is 0.106.
Step-by-step explanation:
The information provided is as follows:
The sales manager chooses 5 different promotions and samples 10 random stores for each different promotion. The F value is 3.4.The degrees of freedom are:
k - 1 = 5 - 1 = 4
n - k = 10 - 5 = 5
Compute the p-value using Excel as follows:
[tex]p-value=P(F_{(k-1,n-k)}>3.4)\\\\=P(F_{(4,5)}>3.4)\\\\=F.DIST.RT(3.4,4,5)\\\\=0.106[/tex]
Thus, the correct p-value is 0.106.

Answer:
(8.75, 2.5)
Step-by-step explanation:
When they ask what point (n,a) corresponds to this, they want a coordinate with an x-value of 8.75.
If we look on the graph, we can see that the a value is around 2.5 quarts of strawberries, so for our point, we will write (8.75, 2.5)
Use the graph below. Explain why the intervals on the horizontal axis could make the graph misleading
45.54
a. The intervals are not comparable. The shorter bar spans more than 10 years
b. The intervals are appropriately labeled
c. The intervals are not comparable, but the data on the graph is not misleading
d. The vertical axis does not have an appropriate scale
Answer:
(D) I think
Step-by-step explanation:
Lets look at our answer choices; A.
The intervals are not comparable. The shorter bar spans more than 10 years. When it comes to a horizontal axis it doesn't matter how far it expands,just if it's expanded correctly.
B.The intervals are appropriately labeled. There not it goes from 25 to 50 in just in instant few climbs up.
C.The intervals are not comparable, but the data on the graph is not misleading. It is misleading the graphs are incorrectly labeled.
Which brings us to our answer D.The vertical axis does not have an appropriate scale. it goes from 0-25 25-50 and 50-75 then 75-100. that's a short distance for such numbers that are pretty far apart.
