The older a child, the taller they are. Identify the relationship between age and height.
Select the correct answer below:
Age and height are negatively correlated.
The younger a child is, the shorter they are.
Correlation does not prove causation.
The taller a child is, the older they are.

Answers

Answer 1

Answer:

The correct answer is: Age and height are positively correlated.

Positive correlation means that as one variable increases, the other variable also increases. In this case, as a child ages, they also get taller. There are many factors that contribute to a child's height, including genetics, nutrition, and health. However, age is one of the most important factors.

Here are some additional details about the relationship between age and height:

The correlation between age and height is positive and strong. This means that there is a strong relationship between the two variables.

The correlation between age and height is linear. This means that the relationship between the two variables is straight.

The correlation between age and height is not perfect. This means that there are some children who are taller or shorter than expected for their age.

Overall, the relationship between age and height is positive and strong. This means that as a child ages, they also get taller.

Fig. 15.20 shows a composite solid consisting of a cube of edge 28 cm and a square-based pyramid of height 16 cm. Calculate the volume of the solid.​

Answers

The volume of the composite solid consisting of a cube and a square-based pyramid will be 26,099.2 cm³.

The volume of the cube is given by;

V_cube = s³ = 28³

V = 21,952 cm³.

The volume of the pyramid is given by V_pyramid = (1/3)Bh,

where;  B = area of the base and h = height .

The base of the pyramid is a square with sides equal to the base of the cube therefore we have

B = s² = 28² = 784 cm².

Thus, V_pyramid = (1/3)(784)(16)

V  = 4,147.2 cm³.

The total volume of the composite solid is the sum of the volumes of the cube and the pyramid then we get;

V_total = V_cube + V_pyramid = 21,952 + 4,147.2

V_total = 26,099.2 cm³.

Therefore, the volume of the solid is; 26,099.2 cm³.

Answers

In inferential statistics, the objective is to determine the probability of the alternative hypothesis being true or the null hypothesis being true.

This involves using sample data to make inferences and draw conclusions about a larger population. By analyzing the data and performing statistical tests, we assess the likelihood of the alternative hypothesis or the null hypothesis being accurate.

The alternative hypothesis represents a claim or statement that contradicts the null hypothesis and suggests that there is a significant relationship or difference between variables. To determine its probability, statistical methods such as hypothesis testing and p-values are employed. These methods evaluate the strength of evidence against the null hypothesis and support the alternative hypothesis when the evidence is substantial.

Answers

The center and the radius is (h, k) = (-1, 1) and r = √3

Given is a circle equation x² + y² + 2x - 2y - 1 = 0, firstly we will change it in (x-h)² + (y-k)² = r² form and then find the center and the radius,

So,

x² + y² + 2x - 2y - 1 = 0

Add 2 to both side,

x² + y² + 2x - 2y - 1 +2 = 0 + 2

x² + y² + 2x - 2y + 1 + 1 = 2+1

many elementary school students in a school district currently have ear infections. a random sample of children in two different schools found that 11 of 40 at one school and 12 of 30 at the other have ear infections. at the 0.05 level of significance, is there sufficient evidence to support the claim that a difference exists between the proportions of students who have ear infections at the two schools?

Answers

Since the p-value is greater than the significance level of 0.05, we fail to reject the null hypothesis. Therefore, there is not sufficient evidence to support the claim that a difference exists between the proportions of students who have ear infections at the two schools.

To determine if there is sufficient evidence to support the claim that a difference exists between the proportions of students who have ear infections at the two schools, we can use a two-sample z-test for the difference in proportions.

The null hypothesis is that there is no difference between the proportions of students with ear infections at the two schools, while the alternative hypothesis is that there is a difference.

Let p1 be the proportion of students with ear infections at the first school and p2 be the proportion at the second school. The test statistic is given by:

z = (p1 - p2) / sqrt(p_hat * (1 - p_hat) * (1/n1 + 1/n2))

where p_hat is the pooled proportion, n1 and n2 are the sample sizes from the first and second schools, respectively.

The pooled proportion is given by:

p_hat = (x1 + x2) / (n1 + n2)

where x1 and x2 are the number of students with ear infections in each school.

Using the given data, we have:

n1 = 40, n2 = 30

x1 = 11, x2 = 12

p1 = x1/n1 = 11/40 = 0.275

p2 = x2/n2 = 12/30 = 0.4

p_hat = (x1 + x2) / (n1 + n2) = (11 + 12) / (40 + 30) = 0.355

The test statistic is:

z = (0.275 - 0.4) / sqrt(0.355 * 0.645 * (1/40 + 1/30)) = -1.197

Using a standard normal table or calculator, the p-value for a two-tailed test with a test statistic of -1.197 is approximately 0.231.

When Maria took her dog to the vet, she was told that a healthy weight for her breed of dog would be approximately
16 pounds plus or minus
3 pounds. Write an absolute value inequality representing the unhealthy weights for her dog’s breed

Answers

Any weight between 13 and 19 pounds, however, would be considered healthy.

The absolute value inequality can be explained as follows: the absolute value of the difference between the weight of the dog and the healthy weight of 16 pounds represents the distance between the dog's weight and the healthy weight. The inequality states that this distance should be greater than 3 pounds, which means that any weight that is more than 3 pounds away from the healthy weight of 16 pounds is considered unhealthy.

For example, if the dog weighs 12 pounds, then the absolute value of the difference between the weight and the healthy weight is 4 pounds, which is greater than 3 pounds. Therefore, 12 pounds is an unhealthy weight for the breed. Similarly, if the dog weighs 20 pounds, then the absolute value of the difference between the weight and the healthy weight is 4 pounds, which is also greater than 3 pounds. Therefore, 20 pounds is also an unhealthy weight for the breed. Any weight between 13 and 19 pounds, however, would be considered healthy.

Answers

The concurrency of the median of the triangle is P ( -1 , 0 )

Given data ,

Let the triangle be represented as ΔABC

Now , the coordinates of the triangle are A(-4,4) B(2,0) and C(-1,-4)

On simplifying , we get

Midpoint of AB:

x-coordinate: (x₁ + x₂) / 2 = (-4 + 2) / 2 = -1

y-coordinate: (y₁ + y₂) / 2 = (4 + 0) / 2 = 4/2 = 2

Midpoint of BC:

x-coordinate: (x₂ + x₃) / 2 = (2 + (-1)) / 2 = 1/2 = 0.5

y-coordinate: (y₂ + y₃) / 2 = (0 + (-4)) / 2 = -4/2 = -2

Midpoint of AC:

x-coordinate: (x₁ + x₃) / 2 = (-4 + (-1)) / 2 = -5/2 = -2.5

y-coordinate: (y₁ + y₃) / 2 = (4 + (-4)) / 2 = 0

Now, we have the midpoints of the sides of the triangle:

Midpoint of AB: (-1, 2)

Midpoint of BC: (0.5, -2)

Midpoint of AC: (-2.5, 0)

The point of concurrency of the medians is the centroid of the triangle, which can be found by taking the average of the midpoints.

x-coordinate: (-1 + 0.5 - 2.5) / 3 = -3 / 3 = -1

An closed box with a square base is to have a volume of 7500 cm3. What should the dimensions of the box be if the amount of material used is to be minimum? (Use decimal notation. Give your answers to three decimal places. ) Recall: The surface area of a rectangular box is: =2⋅⋅+2⋅⋅ℎ+2⋅⋅ℎ , where = length, = width, and ℎ= height. Hint: Draw a sketch of the box and note that the base of the box is a square

Answers

To minimize the amount of material used for the box, we want to minimize its surface area. Since the base of the box is a square, let's denote its side length as s. Then, the height of the box can be expressed as 7500/s^2, using the given volume.

Using this information, we can express the surface area of the box as a function of s: A(s) = 2s^2 + 4sh, where h is the height of the box. Substituting 7500/s^2 for h, we get A(s) = 2s^2 + 4(7500/s^2)s.

To find the minimum amount of material used, we need to find the value of s that minimizes A(s). We can do this by finding the critical points of A(s) and then using the second derivative test to determine if they correspond to a minimum. Taking the derivative of A(s) and setting it equal to zero, we get:

A'(s) = 4s - 30000/s^3 = 0

Solving for s, we get s = 15∛125 ≈ 12.247.

To confirm that this value corresponds to a minimum, we take the second derivative of A(s) and evaluate it at s = 12.247:

A''(s) = 4 + 90000/s^4

A''(12.247) ≈ 0.143

Since A''(12.247) is positive, we can conclude that s = 12.247 corresponds to a minimum of A(s). Therefore, the of the box should be approximately 12.247 cm by 12.247 cm by 41.666 cm to minimize the amount of material used.

The owner of a store buys a wooden branch for two dollars is Shemar up the place by 75% at the end of the season she sells the meaning branches for 30% off how much profit does the owner make on each branch at the end of the season

Answers

Let's calculate the profit made by the owner on each branch at the end of the season. The owner buys a wooden branch for $2. After marking up the price by 75%, the selling price becomes:

$2 + ($2 * 0.75) = $2 + $1.50 = $3.50

However, at the end of the season, the owner sells the branches for 30% off. So the selling price after the discount is:

$3.50 - ($3.50 * 0.30) = $3.50 - $1.05 = $2.45

To calculate the profit made on each branch, we subtract the original cost from the selling price:

$2.45 - $2 = $0.45

find the points on the ellipse 4x^2+y^2=4 that are farthest away from the point (1 0)

Answers

So the points on the ellipse that are farthest away from the point (1,0) are: (1/15)(2 + sqrt(394)), ±sqrt(4 - 4(1/15)(2 + sqrt(394))^2 )and (1/15)(2 - sqrt(394)), ±sqrt(4 - 4(1/15)(2 - sqrt(394))^2).

We want to find the points on the ellipse that are farthest away from the point (1,0). The distance between two points (x1, y1) and (x2, y2) is given by the distance formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

So, we need to maximize the distance d, subject to the constraint that the point (x, y) lies on the ellipse 4x^2 + y^2 = 4.

Using Lagrange multipliers, we set up the following system of equations:

f(x, y) = (x - 1)^2 + y^2 = λg(x, y) = λ(4x^2 + y^2 - 4)

Taking the partial derivatives with respect to x, y, and λ, we get:

fx = 2(x - 1) = 8λx

fy = 2y = 2λy

g(x, y) = 4x^2 + y^2 - 4 = 0

From the second equation, we can see that y = 0 or λ = 1. If y = 0, then the first equation simplifies to:

(x - 1)^2 = λ(4x^2 - 4)

Solving for λ and substituting into the equation for g(x,y), we get:

4x^2 - (x - 1)^2 - 4 = 0

Simplifying, we get:

15x^2 - 2x - 11 = 0

Using the quadratic formula, we get:

x = (1/15)(2 ± sqrt(394))

When x = 1, the series becomes (-1)^n1^n-1 = (-1)^(n-1) which also diverges.
Therefore, the interval of convergence is (-1, 1) in interval notation.

Note that the endpoints are not included in the interval of convergence because the series diverges at those points.

The radius of convergence is R = 1 and the interval of convergence is (-1, 1).

To find the radius of convergence, we can use the ratio test:
lim┬(n→∞)⁡|(-1)^(n+1)x^n|/|(-1)^(n)x^(n-1)| = lim┬(n→∞)⁡|x|/1 = |x|
The series converges if |x| < 1 and diverges if |x| > 1. So the radius of convergence is R = 1.
To find the interval of convergence, we need to test the endpoints x = -1 and x = 1. When x = -1, the series becomes (-1)^n(-1)^n = 1, which is a divergent series. When x = 1, the series becomes (-1)^n, which is an oscillating series that does not converge.
Therefore, the interval of convergence is (-1, 1), where -1 is excluded and 1 is included, since the series converges for -1 < x < 1 and diverges for x ≤ -1 and x ≥ 1.
In summary, the radius of convergence is R = 1 and the interval of convergence is (-1, 1).

A drug company claims that its new painkiller has exactly 5 mg. of codeine. You test the claim at a significance level (alpha) of 0.05. You randomly sample 100 pills made by the company and find the sample mean to be 4.7 milligrams of codeine with a sample standard deviation of 0.75 grams.
(a) What are the null and alternate hypotheses?
(b) Draw the picture of the distribution of the test statistics (under H0). Include critical value(s) and region(s) of rejection.
(c) What is the calculated (computed) value of the test statistic?
(d) What is your conclusion?

Answers

This means that there is evidence to suggest that the mean amount of codeine in the painkiller is not exactly 5 mg.

(a) The null hypothesis is that the mean amount of codeine in the painkiller is exactly 5 mg. The alternate hypothesis is that the mean amount of codeine in the painkiller is not exactly 5 mg.
(b) The picture of the distribution of the test statistics (under H0) would be a normal distribution with a mean of 5 mg and a standard deviation of 0.75 mg/sqrt(100) = 0.075 mg. The critical values for a two-tailed test at a significance level of 0.05 are -1.96 and +1.96. The region(s) of rejection are the values outside of this range. This can be represented in a graph as shaded areas on both sides of the distribution curve.
(c) The calculated value of the test statistic is (4.7 - 5) / (0.75 / sqrt(100)) = -2.67.
(d) Since the calculated value of the test statistic (-2.67) falls within the region of rejection, we reject the null hypothesis. This means that there is evidence to suggest that the mean amount of codeine in the painkiller is not exactly 5 mg.
