Solve the system for x and y:
Answer:
x = 6, y = -3
Step-by-step explanation:
[tex]\frac{x}{y + 1} = -3\\\frac{y}{x-3} = -1[/tex]
x = -3(y+1) - Isolate for x or y (I chose x)
x = -3y -3
Plug in x into y
[tex]\frac{y}{x-3} = -1\\\frac{y}{(-3y -3) - 3} = -1\\\frac{y}{-3y -6} = -1\\y = -1(-3y - 6)\\y = 3y + 6\\-2y = 6\\y = -3[/tex]
Plug y back into equation
[tex]\frac{x}{y+ 1} = -3\\\frac{x}{(-3)+ 1} = -3\\\frac{x}{-2} = -3\\x = -3(-2)\\x = 6[/tex]

Determine if the correlation between the two given variables is likely to be positive or negative, or if they are not likely to display a linear relationship.
your daily calorie intake and your GPA
The correlation between your daily calorie intake and your GPA is not likely to be immediately apparent, and it would require further investigation to determine whether there is a positive or negative correlation, or no linear relationship between the two variables.
It is difficult to predict the correlation between your daily calorie intake and your GPA as they are not obviously related variables. However, it is possible that there may be a weak or indirect relationship between the two variables.
If a person is consuming a well-balanced diet with the right amount of nutrients, vitamins, and minerals, they may have the energy and focus necessary to perform well academically. In this case, there may be a positive correlation between calorie intake and GPA. Alternatively, if a person is consuming an excessive amount of calories from unhealthy foods, they may be more likely to experience health problems that could impact their academic performance. In this case, there may be a negative correlation between calorie intake and GPA.
On the other hand, there may be no direct linear relationship between the two variables, and other factors such as sleep, stress, exercise, and overall health may have a greater impact on academic performance than daily calorie intake.

In the U.S., shoe sizes are defined differently for men and women, but in Europe, both sexes use the same shoe size scale. The accompanying histogram shows the European shoe sizes of 269 male and female college students, converted from their reported U.S. shoe sizes. What might be the problem with either the mean or the median as a measure of center?
To accurately represent the shoe sizes for men and women separately, it would be better to compute the mean or median shoe size for each group separately and compare them.
The problem with either the mean or the median as a measure of center in this case is that the data is not separated by gender, and the shoe size distributions for men and women are likely to be different. Therefore, computing the mean or median shoe size across all students may not accurately represent the typical shoe size for men or women separately.
For example, if the men in the sample have, on average, larger shoe sizes than the women, then the mean shoe size across all students may be biased towards the larger sizes, even though the majority of the students are women. On the other hand, if there are a few male students with very large shoe sizes, then the median shoe size across all students may be biased towards the larger sizes as well, even if most of the students are women with smaller shoe sizes.
To accurately represent the shoe sizes for men and women separately, it would be better to compute the mean or median shoe size for each group separately and compare them. Alternatively, a better measure of center might be to report the mode, which represents the most common shoe size in the data.

how many ways can baseball players and basketball players be selected from baseball players and basketball players?
There are many ways that baseball players and basketball players can be selected from a group of athletes who play both sports.
One way is to use a selection process that allows for both players to be chosen based on their individual merits. For example, a team could use a combination of criteria such as previous performance, physical fitness, athleticism, and skill level to select the most suitable players for each sport. This could be done by assigning each player a score based on these criteria and then selecting the highest scoring players for each position.Another way to select players from a group of athletes playing both sports is to use a draft system. This system would allow teams to choose players based on the team's needs, rather than individual merits. This could be done by assigning each player an overall ranking and then allowing teams to select players in order of their ranking. A third way to select players from a group of athletes playing both sports is to have a tryout or combine where players can showcase their skills and abilities. This allows teams to evaluate players in a more comprehensive way and make sure they are selecting the best players for their team. Finally, teams can also use a combination of the above methods to select players. For example, they could use a combination of a draft system, individual merit selection, and a tryout/combine to get a better idea of which players are the best fit for their team.

$190 is invested in an account earning 7.1% interest (APR), compounded quarterly. Write a function showing the value of the account after t years, where the annual growth rate can be found from a constant in the function. Round all coefficients in the function to four decimal places. Also, determine the percentage of growth per year (APY), to the nearest hundredth of a percent.
Answer:
Value of account after t years is
[tex]A = \boxed{190( 1.0178)^{4t}}[/tex]
Percentage of growth per year
CAGR = [tex]\boxed{7.31\%}[/tex]
Step-by-step explanation:
The generalized equation for the accrued value of an amount P(the principal) deposited at i% annual interest compounded n times a year for t years is
[tex]A = P\left(1 + \dfrac{r}{n}\right)^{nt}[/tex]
where r = i/100, the interest rate expressed as a decimal
Given P = $190
i = 7.1% ==> r = 7.1/100 = 0.071
Since the interest is compounded quarterly and there are 4 quarters in a year, the interest is compounded 4 times a year so n = 4
[tex]A = 190 \left(1 + \dfrac{0.071}{4}\right)^{4t}[/tex]
[tex]A = 190\left(1 + 0.01775\right)^{4t}}\\\\A = 190( 1.01775)^{4t}[/tex]\
Rounding the annual growth rate to 4 decimal places gives

Compound Annual Growth = = 203.89 - 190 = $13.89
Compound Annual Growth Rage(CAGR) = $13.89/$190 = 0.073105

For lunch, Joan bought a glass of milk for $1. 20, a turkey sandwich for $4. 70, as well as some sherbet for $3. 30. The tax came out to $1. 80, and Joan paid with $19. 0. How much change should Joan receive?
Joan paid with $19.00, she should receive $19.00 - $12.00, which equals $11.30 in change.So Joan should receive 11.30 in change.
Joan should receive $11.30 in change. To calculate this, we must start with the total cost of her items, which comes to $10.20 ($1.20 for the milk, $4.70 for the sandwich, and $3.30 for the sherbet). To this we must add the tax, which was $1.80. This brings the total cost to $12.00. Joan should receive $11.30 in change. To get this answer, we can use the following formula: Change = Total Payment - (Cost of Items + Tax). In this case, the formula would look like this: Change = 19.00 - (1.20 + 4.70 + 3.30 + 1.80). After calculating, the answer is 11.30. So Joan should receive 11.30 in change.

after conducting a one-sample z test, you arrived at a value of 0.2 for the z value. what is your conclusion?
The z value of 0.2 indicates the standardized difference between the sample mean and population mean
The z value is a standardized score that tells us how many standard deviations a sample mean is from the population mean. In other words, it helps us determine the likelihood that the difference between the two means is due to chance or some other factor.
Typically, we use a significance level (often denoted by alpha) to determine if the z value is significant or not. If the z value falls within the critical values for the chosen significance level, we reject the null hypothesis and conclude that there is a significant difference between the two means. If the z value falls outside the critical values, we fail to reject the null hypothesis and conclude that there is not a significant difference.
In your case, with a z value of 0.2, it is important to consider what significance level was used in the test. If the chosen significance level was 0.05. Since 0.2 falls within this range, we would fail to reject the null hypothesis and conclude that there is not a significant difference between the sample mean and population mean.

a standard pair of six-sided dice is rolled. what is the probability of rolling a sum less than or equal to 6 ? express your answer as a fraction or a decimal number rounded to four decimal places.
The probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice is 5/18 or approximately 0.2778.
To calculate the probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice, we need to find the number of ways the dice can be rolled to get a sum less than or equal to 6 and divide it by the total number of possible outcomes.
There are 6 x 6 = 36 possible outcomes when rolling a pair of dice, since there are 6 possible outcomes for each die. To get a sum less than or equal to 6, the only possible outcomes are:
1+1 = 2
1+2 = 3
1+3 = 4
1+4 = 5
2+1 = 3
2+2 = 4
2+3 = 5
3+1 = 4
3+2 = 5
4+1 = 5
There are 10 possible outcomes that result in a sum less than or equal to 6. Therefore, the probability of rolling a sum less than or equal to 6 is:
P(sum less than or equal to 6) = number of favorable outcomes / total number of possible outcomes
P(sum less than or equal to 6) = 10 / 36
Simplifying this fraction, we get:
P(sum less than or equal to 6) = 5 / 18
Therefore, the probability of rolling a sum less than or equal to 6 when rolling a pair of six-sided dice is 5/18 or approximately 0.2778 when rounded to four decimal places.
