The number of  brownies have nuts is 3.

We are given that;

Number of brownies=15

Number of boxes he handed out=1 4/5

Now,

To find the number of brownies that have nuts, we need to multiply the total number of brownies he handed out by the fraction of brownies that have nuts.

First, we need to find the total number of brownies he handed out. He handed out 1 4/5 boxes, which is equal to 9/5 boxes. To find the number of brownies in 9/5 boxes, we need to multiply 9/5 by 15, which is the number of brownies in one box. This gives us 9/5 * 15 = 27 brownies.

Next, we need to find the fraction of brownies that have nuts. The problem tells us that 1/9 of the brownies have nuts. This means that for every 9 brownies, one has nuts.

Finally, we need to multiply the total number of brownies by the fraction of brownies that have nuts. This gives us 27 * 1/9 = 3 brownies.

Therefore, by the unitary method the answer will be 3.

Data set A is the correct match for the shape depicted in the image, where the mean, median, and mode are all equal to 40.

The first data set, A, matches with the shape depicted in the image. The mean, median, and mode are all equal to 40.
To understand what these measures represent, let's break them down:
- Mean: The mean is the average of all the values in a data set. In this case, all the values in data set A must add up to 40 when divided by the number of values.
- Median: The median is the middle value in a data set when arranged in ascending order. In this case, the median is also 40, which means that half of the values in data set A are below 40 and half are above 40.
- Mode: The mode is the value that appears most frequently in a data set. Here, 40 is the mode because it occurs more often than any other value in data set A.
Therefore, data set A is the correct match for the shape depicted in the image, where the mean, median, and mode are all equal to 40.

It is false, that the margin of error of a confidence interval is the error from biased sampling methods.

The margin of error of a confidence interval is the amount of accuracy in a sample with respect to the population. It is calculated by taking the sample standard deviation and dividing it by the square root of the sample size. The margin of error helps to quantify the reliability of estimates and provides a range within which the population parameter is likely to fall. It does not refer to errors in sampling methods, which are typically a result of bias. Bias is a systematic error that arises from the sampling procedure, resulting in estimates that are not an accurate representation of the population.

Answer: 2 2/3 miles

Step-by-step explanation:

From the question, we are informed that three runners in a relay race share the 8-mile distance equally.

The number of miles that each runner travel will be the total miles divided by number of runners. This will be:

= 8/3

Note that the angles of the triangle whose vertexes are the centers of the circles are  50.48°, 58.99°, 70.53°.

Three circles with radii 4, 5, and 6 from a triangle whose sides are the sum of their radii in pairs.

Thus, the sides of the triangle are

4 + 5, 4 + 6, and 5+6.

⇒ 9,, 10, 11.

To find the interior angles

CosC = a² + b² + c²/ 2ab

Cost C = (9² + 10² -11²) / (2 x9x10)

= 81 + 100 -121/180

= 60/180

= 1/3

C = 70.53°

The probability of adding either ground beef or onion as the first ingredient  0.25 or 25%.

If there are a total of 8 ingredients and 2 of them are either ground beef or onion, then the probability would be:

Probability = (Number of desired outcomes) / (Total number of possible outcomes)

           = 2 / 8

           = 1 / 4

           = 0.25

So, the probability of adding either ground beef or onion as the first ingredient is 0.25 or 25%.

In this case, we have a total of 8 ingredients, out of which 2 are either ground beef or onion. When selecting the first ingredient, there are 8 possible outcomes. Since we want to calculate the probability of adding either ground beef or onion as the first ingredient, we count the number of desired outcomes, which is 2 (either ground beef or onion). Dividing the number of desired outcomes by the total number of possible outcomes gives us the probability.

The probability of adding either ground beef or onion as the first ingredient is 0.25 or 25%. This means that there is a 25% chance that either ground beef or onion will be the first ingredient added, assuming the ingredients are added randomly without any specific order.

To solve the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0, we can use algebraic methods and the unit circle to determine the values of x that satisfy the equation.

1. Start by rearranging the equation to a quadratic form: \(6sin^2(x)\) + 6sin(x) + 1 = 0.

2. Notice that the equation resembles a quadratic equation in terms of sin(x). Let's substitute sin(x) with a variable, such as u: \(6u^2\) + 6u + 1 = 0.

3. Solve this quadratic equation for u. You can use the quadratic formula or factorization methods to find the values of u. The solutions are u = (-3 ± √3) / 6.

4. Since sin(x) = u, substitute back the values of u into sin(x) to obtain the values for sin(x): sin(x) = (-3 ± √3) / 6.

5. To find the values of x, we can use the inverse sine function. Take the inverse sine of both sides: x = arcsin[(-3 ± √3) / 6].

6. The arcsin function has a range of [-π/2, π/2], so the values of x lie within that range. Use a calculator to find the approximate values of x based on the values obtained in step 5.

7. Plot the obtained x-values on the graph to show the solutions of the equation \(6sin^2(x)\) + 6sin(x) + 1 = 0. The graph will illustrate the points where the curve intersects the x-axis.

To calculate the volume of a 1.420M NaOH solution required to titrate 25mL of a 4.500M H2SO4 solution, we can use the stoichiometry of the balanced chemical equation and the concept of molarity.

The balanced chemical equation for the reaction between NaOH and H2SO4 is:

2NaOH + H2SO4 -> Na2SO4 + 2H2O

From the equation, we can see that 2 moles of NaOH react with 1 mole of H2SO4 to form 1 mole of Na2SO4 and 2 moles of H2O.

To find the volume of the NaOH solution required, we can use the molar ratios between NaOH and H2SO4. Since the molarity of the H2SO4 solution is given as 4.500M, it represents the number of moles of H2SO4 per liter.

By using the molar ratios from the balanced equation, we can calculate the moles of NaOH required to react with the given moles of H2SO4. Then, by dividing the moles of NaOH by the molarity of the NaOH solution, we can find the volume in liters. Finally, we convert the volume to milliliters.

Please provide the volume of the H2SO4 solution used in milliliters, as it is needed to perform the calculation.

So the area of the rectangle (or lane) whose length is 19 feet and whose width is the free throw line, together with the two circles at each end of the court that surround the free throw line, is approximately 450.39 square feet.

Since the circle at each end of the court that surrounds the free throw line is the same size as the jump ball circle, they both have the same radius. Let's call this radius "r".

The diameter of the circle is equal to the width of the lane, which is the same as the width of the free throw line. Therefore, the diameter of the circle is also 12 feet (the width of the free throw line is always 12 feet).

We know that the area of a circle is given by the formula A = πr^2, so the area of each circle is πr^2.

The rectangle (or lane) has a length of 19 feet and a width of 12 feet. Therefore, its area is simply the product of its length and width, which is:

A = 19 feet * 12 feet

A = 228 square feet

Since there are two circles, the total area of the circles is 2πr^2.

We know that the diameter of the circle is equal to the width of the lane, which is 12 feet. Therefore, the radius is half of the diameter, or:

r = 12 feet / 2

r = 6 feet

Now we can calculate the area of the circles:

A = 2πr^2

A = 2π(6 feet)^2

A = 72π square feet

Therefore, the total area of the rectangle and circles (or lane and circles) is:

A_total = A_rectangle + A_circles

A_total = 228 square feet + 72π square feet

A_total ≈ 450.39 square feet

So the area of the rectangle (or lane) whose length is 19 feet and whose width is the free throw line, together with the two circles at each end of the court that surround the free throw line, is approximately 450.39 square feet.
