Is this not 2? I got 2 and it was wrong

Answer:

30%

Step-by-step explanation:

Original price (100%) = $130

Discounted price = $91

Discount = 130-91 = $39

$130 = 100%

$1 = 100/130

$39 = 100/130 × 39 = 30 %

% discount = 30%

Answer:

61.13

Answer: A. 0

Step-by-step explanation: To determine the number of solutions for the system of equations x - y = 7 and y = sqrt(3x + 3) - 2, we can substitute y in the first equation with the expression for y in the second equation, giving us x - (sqrt(3x + 3) - 2) = 7. Simplifying this equation, we get sqrt(3x + 3) = -x + 9.

Since the square root of a number is always non-negative, we can conclude that there are no solutions to this system of equations. Therefore, the answer is A. 0.

One-half of the dogs in each shelter are between the weights represented by the first and third quartiles, which are approximately 20-55 pounds for the first shelter and 25-65 pounds for the second shelter, respectively.

A box plot is a visual representation of a set of data that shows the median, quartiles, and outliers of the data. The box represents the middle 50% of the data, with the bottom and top edges of the box representing the first and third quartiles, respectively. The line inside the box represents the median, or the middle value of the data set. The "whiskers" extend from the edges of the box to the minimum and maximum values of the data set, but outliers beyond the whiskers are represented as individual points.

Now, let's look at the two box plots showing the weights of dogs in two different animal shelters. One-half of the dogs in each shelter are between the first and third quartiles, which are represented by the edges of the box in each plot.

If we take the first box plot, we can see that the first quartile is approximately 20 pounds and the third quartile is approximately 55 pounds. Therefore, one-half of the dogs in this shelter weigh between 20 and 55 pounds.

The volume of the spherical cap is approximately 186624π cubic units.

A spherical cap is a portion of a sphere that lies between two parallel planes that intersect the sphere. To find the volume of a spherical cap with radius and height , we can use the following formula:

V = \(\frac{\pi h^{2}}3(3r-h)\)

where is the radius of the sphere.

Substituting the given values of and , we get:

V=\(\frac{\pi (24)^{2}}3(3*37-24)\)

Simplifying this expression, we obtain:

V= \(\frac{\pi (576)}3(81)\)

V=186624\(\pi\)

We do not have enough evidence to conclude that the average height of 7th graders has increased.

Null Hypothesis (H0): The average height of 7th graders has not increased (μ <= 145 cm)

Alternative Hypothesis (Ha): The average height of 7th graders has increased (μ > 145 cm)

We will use a one-tailed test since we are testing for an increase in height.

We need to compute the test statistic to make a decision.

z = (X - μ) / (σ / √n)

where X is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Here, X = 147 cm, μ = 145 cm, σ = 20 cm, and n = 200.

z = (147 - 145) / (20 / √200) = 1.41

Using a one-tailed table with a significance level of 0.01, the critical value is 2.33.

Since the calculated test statistic (1.41) is less than the critical value (2.33), we fail to reject the null hypothesis.

Therefore, we do not have enough evidence to conclude that the average height of 7th graders has increased.

From the complete question, the shape is a regular hexagon.

This means that n = 6.

So, we have:

Let x be the coefficient of y^2 in the expression 2x^2y+15xy^2-7y. So x=0.

What is co-efficient?

A coefficient is a multiplicative factor in a polynomial, series, or expression in mathematics. It is typically a number, although it can also be any expression (including variables such as a, b and c). They may also be referred to as parameters if the coefficients are variables in and of themselves.

Write an example of co-efficient.

As an illustration, 6z stands for 6 times z. Since z is a variable, 6 is a coefficient. For variables without a value, the coefficient is 1.

The given algebraic expression is 2yx^2+15xy^2-7y.

The terms are xy^2, yx^2 any y^2

So the co-efficient of y^2 is 0

By using Chebyshev's inequality, n = (o² * δ) / e² samples are sufficient to guarantee that P(|Sn - u| > e) < δ for the sample mean estimator.

In order to solve this question we need to consider Optimal Mean Estimation via Concentration Inequalities and use sample mean and median of means estimator.

To find the sample size n that guarantees P(|û - u| > e) < δ using Chebyshev's inequality, follow these steps:

1. Define Sn as the sample mean estimator:

Sn = (1/n) * Σ(Xi) for i = 1 to n.

2. We know the variance o² is known, and Chebyshev's inequality states that P(|X - E(X)| > k * σ) ≤ 1/k², where X is a random variable, E(X) is the expected value of X, σ is the standard deviation, and k is a constant.

3. Apply Chebyshev's inequality to Sn - u:

P(|Sn - u| > k * (o / sqrt(n))) ≤ 1/k², where k = e * sqrt(n) / o.

4. We want P(|Sn - u| > e) < δ, so we can rewrite Chebyshev's inequality as 1/k² < δ. Substitute k with e * sqrt(n) / o: 1/((e * sqrt(n) / o)²) < δ.
5. Solve for n: n = (o² * δ) / e².

By using Chebyshev's inequality, n = (o² * δ) / e² samples are sufficient to guarantee that P(|Sn - u| > e) < δ for the sample mean estimator.

The 95% confidence interval for the proportion of horses with enteroliths that are fed at least two flakes of alfalfa per day is approximately 0.597 to 0.834.

To calculate the confidence interval, we can use the formula for proportions. The point estimate for the proportion is calculated by dividing the number of horses fed two or more flakes of alfalfa (42) by the total sample size (62), resulting in a point estimate of 0.677.

To determine the margin of error, we use the formula:

Margin of Error = Critical Value * Standard Error

The critical value is obtained from the standard normal distribution, corresponding to a 95% confidence level. For a two-tailed test, the critical value is approximately 1.96.

The standard error is calculated using the formula:

Standard Error = √[(p * (1 - p)) / n]

where p is the point estimate and n is the sample size.

Plugging in the values, we find that the standard error is approximately 0.064.

Next, we calculate the margin of error:

Margin of Error = 1.96 * 0.064 ≈ 0.125

Finally, we construct the confidence interval by subtracting and adding the margin of error to the point estimate:

Lower bound = 0.677 - 0.125 ≈ 0.552

Upper bound = 0.677 + 0.125 ≈ 0.80

Therefore, the 95% confidence interval for the proportion of horses with enteroliths that are fed at least two flakes of alfalfa per day is approximately 0.597 to 0.834.

The the equation of a line that passes through the point (2, −10) and is parallel to 14x+2y=6 is 7x + y + 8 = 0.

A straight line is just a line with no curves. So, a line that extends to both sides till infinity and has no curves is called a straight line.

The equation of a line parallel to a given line will have the same slope as the given.

The equation of a line having a slope m and passing through the point (x', y') is written as

y - y' = m (x - x').

This is called point - slope equation of a straight line.

In the given equation,

14x+2y=6

⇒ 2y = -14x + 6

⇒ y = -7x + 3

Comparing it with standard equation of a straight line; y = m x + c, the slope m of the given line = -7

Therefore equation of the line parallel to the given line and passing through point (x', y') = (2, -10) would be:

y - (-10) = -7x + 2

⇒ y + 10 = -7x + 2

⇒ 7x + y + 8 = 0

Hence the required equation of line 7x + y + 8 = 0

Check the picture below.

let's recall that on an isosceles triangle, twin sides make twin angles.

====================================================

Explanation:

See the diagram below. We're looking for the area of the shaded region in blue.

This is known as an inscribed circle since the circle is inside the square, touching each side at one point. This circle is as large as possible without spilling outside the square. Think of a balloon that has been inflated as much as possible to fill the room (it touches every wall at a tangent point).

The square has area s^2 = 6^2 = 6*6 = 36 square inches.

The circle has area pi*r^2 = pi*3^2 = 9pi square inches exactly. Note how I cut the diameter (6) in half to get the radius (3).

The blue shaded area is the difference of the square and circle areas, so we have 36 - 9pi as the exact area of the shaded region.

Using your calculator, you should find that 36-9pi = 7.72566611769187 approximately. I'm using my calculator's stored version of pi as opposed to something like pi = 3.14; but you may need to ask your teacher for clarification about what version of pi to use.

When rounding to the nearest tenth, we then get roughly 7.7 square inches as our final answer.
