what exactly is standard deviation? and pls gimme an example
Answers
Answer:
The standard deviation is the average amount of variability in your data set. It tells you, on average, how far each score lies from the mean.
The standard deviation measures the spread of the data about the mean value. It is useful in comparing sets of data which may have the same mean but a different range. For example, the mean of the following two is the same: 15, 15, 15, 14, 16 and 2, 7, 14, 22, 30. However, the second is clearly more spread out.

Evaluating the Effectiveness of the Australian Free Trade Agreement and Singapore Free Trade Agreement in Enhancing the US Economy
The Australian Free Trade Agreement (AUSFTA) and the Singapore Free Trade Agreement (SFTA) have both had positive impacts on the US economy. However, the AUSFTA appears to have been more effective overall, fostering closer economic ties, expanding export opportunities, and creating jobs in various sectors. While concerns exist regarding trade deficits and potential impacts on domestic industries, the AUSFTA's benefits outweigh these drawbacks. The SFTA has also brought advantages such as increased market access and intellectual property protection, but concerns about trade deficits and labor and environmental standards raise questions about its effectiveness in bettering the US economy.
The AUSFTA has provided significant benefits to the US economy. It has eliminated or reduced tariffs, facilitating increased exports of agricultural products and promoting investment and job growth. Despite concerns over trade deficits and potential impacts on domestic industries, the overall positive effects of the agreement, including closer economic ties and increased market opportunities, make it an effective tool in enhancing the US economy.
On the other hand, the SFTA has also brought advantages to the US economy, including improved market access and intellectual property protection. However, criticisms regarding trade deficits and labor and environmental standards raise questions about its overall effectiveness in bettering the US economy. While these concerns should be addressed and monitored, the AUSFTA appears to have had a stronger positive impact, considering its contributions to export growth, investment, and job creation.
In conclusion, both the AUSFTA and SFTA have had positive impacts on the US economy. However, the AUSFTA's benefits, including increased export opportunities, closer economic ties, and job creation, make it the stronger option. While concerns exist for both agreements, addressing these issues and maximizing the advantages of free trade can contribute to the continued enhancement of the US economy.

Answers
If there is a correlation between the number of employees and customer satisfaction in two different Buffalo Wild Wings stores, we need to perform a Pearson's correlation coefficient analysis.
To run stats testing on sales data from two different Buffalo Wild Wings stores, we need to use a correlation analysis. Specifically, we need to use Pearson's correlation coefficient to determine if there is a relationship between the number of employees and customer satisfaction. The Pearson's correlation coefficient ranges from -1 to +1, with -1 indicating a perfect negative correlation and +1 indicating a perfect positive correlation. If the coefficient is close to zero, it indicates that there is no correlation.
The data we need to collect includes the number of employees in each store and the sales data for a specific period. We also need to gather customer satisfaction data, which can be collected through surveys or other feedback mechanisms. Once we have the data, we can use a statistical software program like SPSS or Excel to perform the correlation analysis.
If the correlation coefficient is positive and statistically significant, it means that there is a relationship between the number of employees and customer satisfaction. This could mean that more employees lead to better customer service, which in turn leads to higher customer satisfaction and sales. However, if the correlation is negative or not statistically significant, it means that there is no relationship between the two variables.
In conclusion, to determine if there is a correlation between the number of employees and customer satisfaction in two different Buffalo Wild Wings stores, we need to perform a Pearson's correlation coefficient analysis. Gathering accurate data and using statistical software will allow us to determine if there is a significant relationship between the variables.

Which number is NOT a solution to the inequality 14n − 46 ≤ 2(7 − 8n) ?
Answers
Answer:
(a)4
Step-by-step explanation:
First you would distribute the 2 within the parentheses and it becomes 14n-46 <= 14-16n. Then you would find the smallest coeficent and do the inverse operation so you would have to add 16n to 14n and get 30n. Your equation is now 30n-46<=14. Now you want to isolate the variable by doing the inverse operation of -46. You would then add 46 to positive 14 and get 60. Your eqaution now is 30n<=60. Your last step is to divide 30 on each side which leaves you with n<=2.

A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 20 miles per gallon of gas. During one particular week, the two cars went a combined total of 1725 miles, for a total gas consumption of 60 gallons. How many gallons were consumed by each of the two cars that week?
Answers
The gallon used by the first car is 35 gallons and the gallon used by the first car is 25 gallons.
How many gallons is used by each car?The first step is to form a system of linear equation:
35a + 20b = 1725 equation 1
a + b = 60 equation 2
Where:
a = gallons used by the first carb = gallons used by the second carThe elimination method would be used to solve this question.
Multiply equation 2 by 35:
35a + 35b = 2100 equation 3
Subtract equation 1 from equation 3:
15b = 375
Divide both sides of the equation by 15:
b = 375 / 15
b = 25
Substitute for b in equation 2 :
a + 25 = 60
a = 60 - 25
a = 35

The given value is 1.4 × 109 km3 to be converted into
m3.1 km = 1000 m.
Hence,
1 km3 = (1000 m)3 = 109 m3.
Therefore,
1.4 × 109 km3 = 1.4 × 109 × (109 m3/km3) = 1.4 × 1018 m3.
Hence, 1.4 × 109 km3 is equal to
1.4 × 1018 m3.
To convert
1.4 × 109 km3
into m3, the given value is multiplied by

When Bruce got his first job, he put $6,225 of his earnings into an investment account to save for retirement. The value of the account is predicted to double each decade.
If Bruce makes no other deposits or withdrawals, what can he predict the value of his investment account to be after 3 decades?
Answers
Answer: Bruce can predict the value of his investment account to be $49,800 after 3 decades
Step-by-step explanation:
If the value of the investment account doubles every decade, then after one decade (10 years), it will be worth $6,225 x 2 = $12,450.
After two decades (20 years) it will be worth $12,450 x 2 = $24,900.
Finally, after three decades (30 years), it will be worth $24,900 x 2 = $49,800.
Therefore, Bruce can predict the value of his investment account to be $49,800 after 3 decades if he makes no other deposits or withdrawals.
Convert the equation –9x2 25y2 – 100y – 125 = 0 into standard form.
Answers
the standard form of the equation -9x²+25y²-100y = 125 is x²/25 + (y-2)²/9 = 1
Add 125 to both sides of the equation.
-9x²+25y²-100y = 125
Complete the square for 25y²-100y
25(y-2)²-100
Substitute 25(y-2)²-100 for 25y²-100y in the equation
-9x²+25y²-100y = 125
-9x²+25(y-2)²-100 = 125
Move −100 to the right side of the equation by adding 100 to both sides.
-9x²+25(y-2)² = 125 +100 = 225
Divide each term by 225 to make the right side equal to one.
-9x²/225 +25(y-2)²/225 = 225/225
Simplify each term in the equation in order to set the right side equal to 1. The standard form of an ellipse or hyperbola requires the right side of the equation to be 1.

Answers
The given statement When inserting a value into a partially-filled array in descending order, the insertion position is indeed the index of the first value smaller than the value being inserted is true.
What is partially filled array?
A partially filled array, also known as a sparse array, is an array data structure where not all elements are populated with values. In other words, it is an array that contains empty or uninitialized elements.
When inserting a new value into this sorted array, we start from the beginning and compare the value with each existing element until we find the first element that is smaller. The insertion position for the new value is the index of this first smaller element.
For example, if we have a partially-filled array [10, 8, 5, 3] and we want to insert the value 6 into the array in descending order, we compare 6 with each element from left to right. The first element smaller than 6 is 5, and its index is 2. Therefore, the insertion position for the value 6 would be index 2, resulting in the updated array [10, 8, 6, 5, 3].
