The equation of the circle is (x - 2)²+ (y - 3)² = 169
Define circleA circle is a two-dimensional form that may be described as a collection of points that are equally spaced apart from a central fixed point. The radius of a circle is the separation between its centre and any other point on the circle. Another way to think of a circle is as the collection of all points at a certain radius from the centre.
The following is the equation for a circle with centres (a, b) and radius r:
(x - a)² + (y - b)² = r²
In this case, the center of the circle is A(2,3), and a point on the circle is B(7,15). The radius of the circle may be calculated using the distance formula:
r = √((7 - 2)² + (15 - 3)²) = √(5² + 12²) = 13
So the equation of the circle is:
(x - 2)² + (y - 3)² = 13²
(x - 2)²+ (y - 3)² = 169
Therefore, the equation of the circle is (x - 2)²+ (y - 3)² = 169

Solve the simultaneous equations:
y=x² + 3x - 18
x + 2y + 14 = 0
Answers
From the second equation, we have:
x + 2y + 14 = 0
Solving for x, we get:
x = -2y - 14
Substituting this expression into the first equation, we get:
y = (-2y - 14)^2 + 3(-2y - 14) - 18
Expanding and simplifying, we have:
y = 4y^2 + 56y + 196
Bringing all terms to one side, we have:
4y^2 + 55y + 196 = 0
We can solve for y using the quadratic formula:
y = (-55 ± sqrt(55^2 - 4(4)(196))) / (2(4))
y = (-55 ± sqrt(1081)) / 8
y ≈ -4.31 or y ≈ -11.44
Substituting each value of y into the expression we found for x earlier, we have:
x = -2(-4.31) - 14 ≈ 6.62
x = -2(-11.44) - 14 ≈ 18.89
Therefore, the solutions to the system of equations are approximately (6.62, -4.31) and (18.89, -11.44).

4. One of the players scored 13. 7 points per game with 4. 1 free throw attempts per game. How does this compare to what the model predicts for this player?
Answers
The model predicts that the player should score around 17.47 points per game based on their 4.1 free throw attempts per game. However, the player's observed score of 13.7 points per game suggests that they may be underperforming compared to what would be expected based on this relationship.
Let us assume that the model predicts a linear relationship between points per game and free throw attempts per game, we can calculate the predicted value of points per game for this player using the regression equation
points per game = slope * free throw attempts per game + intercept
From the given data, we know that the slope of the regression line is 2.6 and the intercept is 7.1. Plugging in the values for this player, we get:
points per game = 2.6 * 4.1 + 7.1 = 17.47
So the model predicts that this player should score approximately 17.47 points per game, which is higher than the observed value of 13.7 points per game. This suggests that this player may be underperforming compared to what would be expected based on their free throw attempts per game.
However, just one player and there may be other factors that could affect their performance beyond just free throw attempts per game.

A manufacturer of hard safety hats for construction workers is concerned about the mean and the variation of the forces helmets transmit to wearers when subjected to a standard external force. The manufacturer desires the mean force transmitted by helmets to be 800 pounds (or less), well under the 1000-pound legal limit, and the standard deviation to be less than 40. A random sample of 31 helmets was tested and the sample mean and variance were found to be 825 pounds and 2350 pounds2, respectively. The manufacturer wants to know if the data provides sufficient evidence to indicate that the standard deviation is significantly less than 40.
Step 1 of 5: Calculate the test statistic for this problem. Round your answer to two decimal places.
Step 2 of 5: Determine the p-value for a lower one-sided alternative hypothesis (left-tail test). The alternative hypothesis for this problem is H1: Ï2 < 1600 lbs2.
Step 3 of 5: What is the rejection region at the 10% level of significance for the test on the variance for a left-tailed alternative hypothesis? The alternative hypothesis for this problem is H1: Ï2 < 1600 lbs2.
Step 4 of 5: State your conclusion using a significance level of 0.05. The alternative hypothesis for this problem is H1: Ï2 < 1600 lbs2.
Step 5 of 5: Calculate a 90% confidence interval for the variance of force on the helmets. Round your answers to four decimal places.
Answers
Step 1: The test statistic is 56.56.
Step 2: Using a chi-square distribution table with 30 degrees of freedom (n - 1), we find that the p-value is less than 0.0001.
Step 3: The rejection region for a left-tailed test with 30 degrees of freedom at the 10% level of significance is any test statistic less than 18.307.
Step 4: The test statistic of 56.56 is greater than the critical value of 18.307.
Step 5: The 90% confidence interval for the variance of force on the helmets is [1615.46, 4123.82]
What is Variance?In statistics, variance is a measure of the spread or dispersion of a set of data points. It is calculated as the average of the squared differences from the mean.
Step 1: To test whether the standard deviation is significantly less than 40, we can use a chi-square test with the null hypothesis H0: [tex]σ^{2}[/tex] ≥ 1600 lbs² and the alternative hypothesis H1: σ² < 1600 lb[tex]s^{2}[/tex]. The test statistic is:
chi-square = (n - 1) *[tex]s^{2}[/tex] / [tex]σ^{2}[/tex]
where n is the sample size, [tex]s^{2}[/tex] is the sample variance, and [tex]σ^{2}[/tex] is the population variance under the null hypothesis.
Substituting the given values, we have:
chi-square = (31 - 1) * 2350 / 1600 = 56.56
Rounding to two decimal places, the test statistic is 56.56.
Step 2: To determine the p-value for a left-tailed test, we need to find the area under the chi-square distribution to the left of the test statistic. Using a chi-square distribution table with 30 degrees of freedom (n - 1), we find that the p-value is less than 0.0001.
Step 3: The rejection region for a left-tailed test with 30 degrees of freedom at the 10% level of significance is any test statistic less than 18.307.
Step 4: Since the test statistic of 56.56 is greater than the critical value of 18.307, we reject the null hypothesis and conclude that there is sufficient evidence to indicate that the standard deviation is significantly less than 40 at the 5% level of significance.
Step 5: To calculate a 90% confidence interval for the variance of force on the helmets, we can use the formula:
[(n - 1) * [tex]s^{2}[/tex]/ chi-square upper, (n - 1) * [tex]s^{2}[/tex] / chi-square lower]
where chi-square upper and chi-square lower are the upper and lower critical values, respectively, from the chi-square distribution table for 30 degrees of freedom at the 5% level of significance. Substituting the given values, we have:
chi-square upper = 45.722
chi-square lower = 18.307
[(31 - 1) * 2350 / 45.722, (31 - 1) * 2350 / 18.307] = [1615.46, 4123.82]

To see why they cannot be the same size, imagine drawing a line from one vertex of each triangle to the opposite side. Since both triangles are equilateral, these lines will bisect the opposite side and form two congruent right triangles.

The set of values for x that satisfies a quadratic inequality is x < -0.5 or x > 1.5
Write down a possible quadratic inequality. Can u show me working it how to do this please. Thanks
Answers
Answer:
To write a possible quadratic inequality, we first need to determine which quadratic function has roots at x = -0.5 and x = 1.5.
We know that the solution to the quadratic inequality is x < -0.5 or x > 1.5, which means that the parabola associated with our quadratic function should not intersect the x-axis between x = -0.5 and x = 1.5.
One quadratic function with roots at x = -0.5 and x = 1.5 is:
(x + 0.5)(x - 1.5) ≤ 0
To see why this is the case, we can use a graphing calculator to graph the quadratic function y = (x + 0.5)(x - 1.5) and observe that the function is negative (i.e., has a y-value less than zero) when x is less than -0.5 or greater than 1.5.
Alternatively, we can use the fact that the product of two factors is less than or equal to zero if and only if one factor is positive and the other is negative.
Since (x + 0.5) is positive for x > -0.5 and negative for x < -0.5, and (x - 1.5) is positive for x > 1.5 and negative for x < 1.5, the inequality (x + 0.5)(x - 1.5) ≤ 0 is true for x < -0.5 or x > 1.5, but false for -0.5 < x < 1.5.
Therefore, a possible quadratic inequality that satisfies the given set of values for x is:
(x + 0.5)(x - 1.5) ≤ 0

What is a measure of the differences of all observations from the mean, expressed as a single number
Answers
The measure of the differences of all observations from the mean, expressed as a single number is called the "standard deviation". It is a commonly used measure of the amount of variability or dispersion within a set of data.
The standard deviation is calculated by taking the square root of the variance, which is the average of the squared differences between each observation and the mean.
It is expressed in the same units as the data itself, and provides a way to understand how spread out the data is from the average or mean value.
A small standard deviation indicates that the data points tend to be close to the mean, while a large standard deviation indicates that the data points are more spread out.
The standard deviation can be used to compare the variability of different sets of data, and can also be used in statistical tests to determine if the difference between two sets of data is statistically significant.

At a local store, 2 bagels and 2 cups of coffee cost $4.40. The cost of 3 bagels and 4 cups of coffee is $7.80.
Part A:
Write a system of equations to represent this situation.
Part B:
Solve the system of equations by substitution and interpret its meaning.
Answers
2b + 2c = 4.40
3b + 4c = 7.80
Part B:
Solve the first equation for b:
2b + 2c = 4.40
b + c = 2.20
Substitute b = 2.20 - c into the second equation:
3(2.20 - c) + 4c = 7.80
6.60 - 3c + 4c = 7.80
c = 1.20
Substitute c = 1.20 into the equation b + c = 2.20:
b + 1.20 = 2.20
b = 1.00
The price of a bagel is $1.00 and the price of a cup of coffee is $1.20.

Students mesured different amounts of water into their beakers for an experiment. If the total amount of water is redistributed equally, how much water will be in the beaker?
1/4 x 6 + 3/4 x 2 + 1/2 + 1 1/4 + 1 1/2 + 1 3/4
Answers
However, each beaker would have the following if there were, say, five beakers: 2.5 units of water are equal to 8.5/5.
what is volume ?Typically, it is expressed in geometric units, which including cubic metres (m3), cubic centimetres (cm3), or cubic feet (ft3), depending on the length unit being used. A formula that is based on an object's shape can be used to determine its volume. The volume of such a rectangular prism, for instance, can be determined by utilizing the formula V = lwh, where l stands for length, w for width, and h for height. A cylinder's volume can be calculated using the formula V = r2h, where r denotes the circle of the base and h the height.
given
We can simply sum the numbers supplied to determine the total volume of water in all the beakers:
1/4 x 6 + 3/4 x 2 + 1/2 + 1 1/4 + 1 1/2 + 1 3/4
= 1.5 + 1.5 + 0.5 + 1.25 + 1.5 + 1.75 (converting mixed values to improper fractions)
= 8.5
8.5 units of water are therefore present in all of the beakers.
Each beaker will have 8.5 divided by the number of beakers if this water is distributed equally among them.
We are unable to provide a precise response since we are unsure of the number of beakers.

If you buy fast food 4 times per week and it costs you about $850 each time, then what should your monthly budget be for fast food?
A. $136
B. $35
C. $100
D. $148
Answers
The Monthly Budget for fast food is Option A. $136.
To determine how much money you should budget for fast food, we need to calculate the total amount of money you spend on fast food each week. To do this, we simply multiply the cost of one fast food meal by the number of meals you buy in a week, which is four in this case.
$850 x 4 = $3400 per week
Next, we need to figure out how much money you spend on fast food per month. To do this, we need to multiply the weekly amount by the number of weeks in a month. Most months have around four weeks, so we will use that as an estimate.
$3400 x 4 = $13600 per month
Therefore, the answer is Option A. $136. You should budget around $136 per month for fast food if you buy it four times a week and it costs you about $850 each time.
