Answer: This means that the salaries of their marketing professionals are not closely related to their job titles. In further explanation, this shows that a professional with a higher job title, may be paid a lower salary when compared to a professional with a lower job title.
A 0.85 R-Squared shows that the points are far from the trend lines. From this, we can assume that the marketing professionals are paid base on commission on sales, and not base on job position.
Step-by-step explanation: R-Squared is a measure used in statistics, to represent how much proportion of the dependent variables that is explained by the independent variables. A high value of R^2 shows a very low correlation between the dependent and independent variables, while a low value of R^2 shows that the dependent and independent variables are closely related. The R-Squared value are a measure of percentage value.

several years ago wolves were reintroduced in to a national park in north carolina in north carolina. Researchers have monitored the populations over the last severals years and the per capita growth rate of the population is .5. If the current population size is 100, what equation would you use to determine how large the population will be in ten years
Answer: [tex]5766.503\ \text{wolves}[/tex]
Step-by-step explanation:
Given
Current Population of wolves is [tex]P_o=100[/tex]
If the growth rate is [tex]=0.5[/tex]
So the population in next year is
[tex]P_1=100+100\times 0.5[/tex]
[tex]P_1=100(1+0.5)[/tex]
similarly [tex]P_2=100(1+0.5)^2[/tex]
So population after n years is [tex]P_n=P_o(1+r)^n[/tex]
Population after 10 years is
[tex]P_{10}=100(1+0.5)^{10}[/tex]
[tex]P_{10}=5766.503\ \text{wolves}[/tex]
A country's balance of payments is divided up into three categories, the
current account, capital account and financial account. The current account
mainly measures
A) the flow of credit.
B) the flow of goods and services.
c) purchases and sales of nonfinancial assets.
D) purchases of sales of stocks and bonds and other financial assets.
Answer:
B) the flow of goods and services
Step-by-step explanation:
Balance of payments (BOP) is a statement of all transactions made between one country and the rest of the world at a particular period of time. It is also called balance of international payment. BoP is divided into current and capital account.
1. The current account: This is account of country's net trade in goods and services, net earnings on cross-border investments, and its net transfer payments. The current account measures the flow of goods and services.
2. The capital account: This is a country's imports and exports of capital and foreign aid. It can also be called financial account.
The sum of all transactions recorded in the balance of payments should be zero.
Balance of payment deficit is when a country's import is higher than its export.
Balance of payment surplus is when a country's export is greater than its import.

Mr. De Leon's Geometry class has 34 students. After lunch everyone returns to the classroom. Within an hour, each person produces 800 BTUs. The room is 25 feet by 32 feet by 12 feet. How many BTUs per cubic foot were produced?
Plz provide the work.
Answer:
2.833 BTUs per cubic foot were produced.
Step-by-step explanation:
BTU's produced by one person = 800
No. of students = 34
Therefore no. of BTU's produced by 34 person = 800 * 34 = 27,200 BTU
Dimension of class 25 feet by 32 feet by 12 feet
Volume of class = length * width * height = 25 * 12 * 32 = 9,600 cubic feet
________________________________________________
BTUs per cubic foot produced = Total BTU's produced by 34 person/ Volume of class
Substituting the value of Total BTU produced and volume of class
BTUs per cubic foot produced = 27,200 BTU/ 9,600 cubic feet
= 2.833 BTUs per cubic foot
2.833 BTUs per cubic foot were produced.

Is Chase able to reach a 100% winning record? Chase (is or isn’t) able to reach a 100% winning record because ________________.
Suppose that after reaching a winning record of 90 in part 2, Chase has a losing streak. How many games in a row would Chase have to lose in order to drop down to a winning record below 55% again?
Chase would have to lose _______ games in order to drop down to a winning
Answer:
Step-by-step explanation:
As of today, Chase has won 18 out of 30 games against his brother. The percentage of games that he has won as of today is
18/30 × 100 = 60%
In order to get 75% wins, let the number of games would be x. Then
(18 + x)/(30 + x) × 100 = 75
100(18 + x) = 75(30 + x)
1800 + 100x = 2250 + 75x
100x - 75x = 2250 - 1800
25x = 450
x = 450/25 = 18
chase has to win 18 games in a row.
In order to get 90% wins, let the number of games would be y. Then
(18 + x)/(30 + x) × 100 = 90
100(18 + x) = 90(30 + x)
1800 + 100x = 2700 + 75x
100x - 75x = 2700 - 1800
25x = 900
x = 900/25 = 36
chase has to win 36 games in a row in order to have a 90% winning record.
(18 + x)/(30 + x) × 100 = 100
100(1800 + x) = 100(30 + x)
1800 + 100x = 3000 + 100x
100x - 100x = 3000 - 1800
Therefore, it is impossible to for chase to reach a 100% winning record because he has already had some losses.
2) for a wining record of 90, the total number of games played is
30 + 36 = 66 games and the total number of wins was 18 + 36 = 54
In order to get 55% losses, let the number of games would be z. Then
(54 + z)/(66 + z) × 100 = 55
100(54 + z) = 55(66 + z)
5400 + 100z = 3630 + 55z
100z - 55z = 3630 - 5400
45z = - 1770
z = - 1770/45 = - 40
chase has to lose 40 games in a row in order to drop down to a winning record below 55% again.
Chase would need to win 6 more games for a 75% win record, 108 more games for a 90% win record. He could never achieve a 100% win record due to past losses. If he reached a 90% win record and then lost, he would need to lose 20 games to drop below a 55% record.
Explanation:To calculate how many games Chase needs to win to achieve a 75% winning record, a solution is needed for the equation (18 + x) / (30 + x) = 0.75, where x represents the additional games won. The solution is x = 6. Therefore, Chase must win an additional 6 games without losing to reach a 75% win record.
For a 90% winning record, we solve the equation (18 + x) / (30 + x) = 0.9. The solution is x = 108. Therefore, Chase must win an additional 108 games without losing to reach a 90% winning record.
Chase is unable to reach a 100% winning record because he has already lost some games and it isn't possible to change those past results.
In the event that Chase reaches a 90% winning record and then begins to lose, we need to find out the number of games he would need to lose to drop to a win rate below 55%. We can solve this by calculating the equation (126) / (138 + y) = 0.55, where y is the lost games. Solving for y, we get y = 20, so Chase would have to lose 20 games in a row.

Answer:
The correct option is (C).
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
Whereas the alternative hypothesis is a contradicting statement tot he null hypothesis. It is denoted by Hₐ.
In this case we need to test whether the average age of online consumers has increased or not.
From previous data we know that the average age of online consumers a few years ago was 24.1 years.
A one-sample mean test can be used to determine whether the mean age has increased or not.
The hypothesis for the test can be defined as follows:
H₀: The average age of online consumers is 24.1 years, i.e. μ = 24.1.
Hₐ: The average age of online consumers is more than 24.1 years, i.e. μ > 24.1.
Thus, the correct option is (C).

Which number line models the expression 1/8-(-3/4)
The number line to model the expression 1/8 - (-3/4) would start at 1/8, and move 6/8 steps to the right to reach 7/8 because subtracting a negative is the same as adding a positive.
Explanation:To solve the mathematical expression 1/8 - (-3/4), we need to understand that subtracting a negative number is equivalent to adding a positive number. Hence, we rewrite the expression as 1/8 + 3/4.
Before you can add these two fractions, they must have a common denominator. The least common denominator (LCD) for 8 and 4 is 8, so we rewrite 3/4 as 6/8 to match the denominator of 1/8.
Now, you can add 1/8 + 6/8 to get 7/8.
A number line that models this expression would start at 1/8 and go forward 6/8 (equivalent to 3/4) steps to end at 7/8.

To model the expression 1/8 - (-3/4) on a number line, you would first convert the expression to 1/8 + 3/4 by changing the minus negative to a plus. Then, find a common denominator and add the fractions to get 7/8. This result is represented on a number line by starting at 1/8 and moving right to reach 7/8.
Explanation:To model the expression 1/8 - (-3/4) on a number line, we need to understand that subtracting a negative is the same as adding its positive counterpart. Therefore, the expression simplifies to 1/8 + 3/4. To add these fractions together, they must have a common denominator. The least common denominator for 8 and 4 is 8. So, we convert 3/4 to 6/8, since 3 multiplied by 2 gives us 6, and 4 multiplied by 2 gives us 8. Adding 1/8 to 6/8 gives us 7/8.
On a number line, we would start at the point representing 1/8 and then move to the right by 6/8 (which represents 3/4) to arrive at 7/8. This portrays the answer to our initial expression, 1/8 - (-3/4) = 7/8.

A high-profile consulting company chooses its new entry-level employees from a pool of recent college graduates using a five-step interview process. Unfortunately, there are usually more candidates who complete the interview process than the number of new positions that are available. As a result, cumulative GPA is used as a tie-breaker. GPAs for the successful interviewees are Normally distributed, with a mean of 3.3 and a standard deviation of 0.4. What percent of candidates have a GPA above 3.9?
Answer:
Only 0.0668 of the candidates, or 6.68%, have a GPA above 3.9.
Step-by-step explanation:
The GPA, according to the question, is a random variable normally distributed. A normal distribution is determined by its parameters. These parameters are the population mean, [tex] \\ \mu[/tex], and the population standard deviation, [tex] \\ \sigma[/tex]. The normal distribution for GPA has a [tex] \\ \mu = 3.3[/tex], and [tex] \\ \sigma = 0.4[/tex].
To find probabilities related to normally distributed data, we can use the standard normal distribution. To use it, we first need to find the corresponding standardized score or z-score for the value we want to obtain the probability. This value, in this case, is x = 3.9. The related z-score or standardized value is given by the formula:
[tex] \\ z = \frac{x - \mu}{\sigma}[/tex] [1]
A z-score tells us the distance from the mean in standard deviations units. A negative value indicates that the value is below the mean. A positive value is, conversely, above the mean.
And we already have all the necessary data to use [1].
Thus
[tex] \\ z = \frac{3.9 - 3.3}{0.4}[/tex]
[tex] \\ z = \frac{0.6}{0.4}[/tex]
[tex] \\ z = 1.5[/tex]
This value for z tells us that the "equivalent" raw score, x = 3.9, is above the mean, and it is at 1.5 standard deviations units from the population mean.
We can find the probabilities for standardized values in the cumulative standard normal table, available on the Internet or in Statistic books (we can also use statistical packages or even spreadsheets).
To use the cumulative standard normal table, we have the z-score as an entry. With this value, we find the z column on this table, and, since it is z = 1.5, we only need to select the first column (which has two decimal places, that is, .00). Then, the cumulative probability for P(z<1.50) = 0.9332.
However, we are asked for the percent of candidates that have a GPA above 3.9 (z-score = 1.50). This probability is the complement of P(z<1.50) or 1 - P(z<1.50). Mathematically
[tex] \\ P(z<3.9) + P(z>3.9) = 1[/tex]
[tex] \\ P(z<1.50) + P(z>1.50) = 1[/tex] (standardized)
[tex] \\ P(z>1.50) = 1 - P(z<1.50)[/tex]
[tex] \\ P(z>1.50) = 1 - 0.9332[/tex]
[tex] \\ P(z>1.50) = 0.0668[/tex]
That is, only 0.0668 of the candidates, or 6.68%, have a GPA above 3.9.
We can see this probability in the graph below.

The mayor of a large city claims that the average net worth of families living in this city is at most $300,000. A random sample of 25 families selected from this city produced a mean net worth $288,000. Assume that the net worth of all families in this city have a normal distribution with the population standard deviation of $80,000. What is the parameter of interest?
Answer:
Check the explanation
Step-by-step explanation:
Below are the null and alternative Hypothesis,
Null Hypothesis, H0: μ = 300000
Alternative Hypothesis, Ha: μ < 300000
Test statistic,
z = (xbar - mu)/(sigma/sqrt(n))
z = (288000 - 300000)/(80000/sqrt(25))
z = -0.75
P-value Approach
P-value = 0.2266
As P-value >= 0.05, fail to reject null hypothesis.
The parameter of interest is the average net worth of families living in the city. Hypothesis testing can be used to evaluate the mayor's claim using a random sample of households. The test statistic can be calculated using the sample mean, sample standard deviation, and sample size.
Explanation:The parameter of interest in this question is the average net worth of families living in the city. The mayor claims that the average net worth is at most $300,000. To determine if this claim is true, a random sample of 25 families is selected. The mean net worth of this sample is $288,000. This mean is an estimate of the population mean net worth.
Based on the information given, the population standard deviation of net worth for all families in the city is $80,000. This information allows us to perform hypothesis testing to evaluate the claim made by the mayor.
Null Hypothesis (H0): The average net worth of families living in the city is $300,000.Alternative Hypothesis (Ha): The average net worth of families living in the city is less than $300,000.Using the sample mean of $288,000, the sample standard deviation ($80,000), and the sample size (25), we can calculate the test statistic.The test statistic is calculated as follows:Test Statistic = (Sample Mean - Population Mean) / (Sample Standard Deviation / sqrt(Sample Size))
Plugging in the values:
Test Statistic = (288,000 - 300,000) / (80,000 / √25)
After calculating the test statistic, we can compare it to the critical value of the test (based on the desired significance level) to determine if we reject or fail to reject the null hypothesis. If the test statistic is less than the critical value, we reject the null hypothesis and conclude that there is evidence to support the claim that the average net worth of families living in the city is less than $300,000.
By providing a random sample from the population, we can use hypothesis testing to evaluate the mayor's claim and determine if there is evidence to support it.

En una granja hay 500 animales. Si hay el triple de vacas que de ovejas, ¿ cuantas animales hay de cada especie
Answer:
Hay 375 vacas y 125 ovejas
Step-by-step explanation:
Para resolver este problema simplemente tenemos que plantear una igualdad entre vacas y ovejas
b = oveja
v = vaca
v = 3b
b + v = 500
reemplazamos la b por (3v) en la segunda ecuacion
b + v = 500
b + 3b = 500
4b = 500
b = 500/4
b = 125
reemplazamos este valor en la primer ecuacion
v = 3b
v = 3(125)
v = 375
Hay 375 vacas y 125 ovejas

The first step is to subtract 6.1 on both sides.The second step is to divide by 1.4 on both sides.The solution is x = -10How to solve linear equation of one variable?Step-1: we have to balance each side by simplifing the equation
Step-2: add/substract constant term on both side of the equation to separate variable and constant term on both side
Step-3: divide the coefficient of the variable on both side to make the coefficient of the variable 1.
So according to asked question,
1.4x+6.1=-7.9
Step 1: subtract 6.1 on both sides.
1.4x+6.1-6.1=-7.9-6.1
⇒1.4x=-14
Step 2: divide by 1.4 on both of the sides.
1.4x/1.4=-14/1.4
⇒x=-10
Therefore,
