a) There is not enough evidence to conclude that cars get significantly better fuel economy with premium gasoline.

In order to test the belief that premium gasoline provides better fuel economy, a study was conducted using 10 cars from a company fleet. Each car was randomly assigned either regular or premium gasoline, and the mileage for each tankful was recorded. The data was analyzed to determine if there is a significant difference in fuel economy between the two types of gasoline.

To evaluate this, a paired t-test can be used since the same cars were tested with both types of gasoline. The null hypothesis would be that there is no difference in fuel economy between regular and premium gasoline, while the alternative hypothesis would be that there is a significant difference.

The results of the study would be analyzed using the appropriate statistical test, such as a paired t-test, to determine the p-value. If the p-value is less than the chosen significance level (e.g., 0.05), then there would be evidence to reject the null hypothesis and conclude that there is a significant difference in fuel economy.

Using the given information and what we know about linear equations, we will find the sketch below.

Here we need to analyze each part separately.

In a coordinate axis where the y-axis represents distance and the x-axis represents time, we will have that:

First, we know that he rides for 30 minutes at a given speed, this will be represented with an increasing linear function.

Then he stops for 20 minutes, this is represented with a horizontal line.

Finally, he returns the motion, but slower than before, so the slope of this line will be smaller than the first one.

So for 0 to 30 we have an increasing linear equation, then for 30 to 50 we have a constant horizontal line, then for 50 to 80 we have another increasing linear equation

The value of x in the chord intersection is 16 units.

The intersecting chord theorem  states that the products of the lengths of the line segments on each chord are equal. In other words, If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal.

Therefore, lets find the value of x in the intersecting chords as follows:

15 × x = 24 × 10

15x = 240

divide both sides of the equation by 15

x = 240 / 15

It is a prime factorization because each base (2,3,5, and 11) is a prime number.

A prime number is one where the only factors of it are 1 and itself.

Instead of saying something like 11^2, we could write 11*11. Similarly, 5^4 could be written as 5*5*5*5. Though it's a good idea to use exponents so you make the prime factorization more compact and save time.

The '3' without an exponent is the same as 3^1. You'll often see that exponent of 1 left out. Again this is to save time.

Answer:

A quadratic function with a double root of -4 can be written in the form:

f(x) = a(x + 4)^2

where "a" is a constant.

Step-by-step explanation:

Since the root is double, we know that the quadratic function touches the x-axis at -4, but does not cross it. This means that the vertex of the parabola is located at x = -4.

To determine the value of "a", we need more information about the function. For example, we could be given a point on the parabola, the y-intercept, or some other information.

Without additional information, we cannot determine a unique quadratic function that has a double root of -4.

There is only 1 linearly independent subset consisting of 1 column for matrix A.

For k=2, 3, 4, and 5, there are no linearly independent subsets since the rank of matrix A is 1.

To find the number of linearly independent subsets consisting of k columns for each of the given matrices, follow these steps:

1. Determine the size and rank of the given matrix.

2. If k is greater than the rank of the matrix, there are no linearly independent subsets of k columns.

3. If k is equal to or less than the rank of the matrix, the number of linearly independent subsets of k columns is given

by the binomial coefficient: C(r, k), where r is the rank of the matrix, and k is the desired number of columns.

For example, let's find the number of linearly independent subsets consisting of k columns for the given matrix A:

Matrix A:
[ 1  2  3]
[ 2  4  6]
[ 3  6  9]

Determine the size and rank of the matrix.

The size of matrix A is 3x3. Its rank is 1, as all rows are linearly dependent.

Check if k is greater than the rank of the matrix.

For k=1, 2, ..., 5, only k=1 is less than or equal to the rank of matrix A (which is 1).

Calculate the number of linearly independent subsets of k columns.

For k=1, use the binomial coefficient formula: C(r, k) = C(1, 1) = 1.

Step-by-step explanation:

The perimeter of the rectangle.

P = 2 ( l + w)

The length of the rectangle is 2.5 m

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Width of the rectangle = w

Length of the rectangle = w - 4

The perimeter of the rectangle = 18 m

P = 2 ( l + w)

18 = 2 (w - 4 + w)

18 = 2 (2w - 4)

9 = 2w - 4

2w = 9 + 4

2w = 13

w = 13/2

w = 6.5 m

Length of the rectangle.

= w - 4

= 6.5 - 4

= 2.5 m

Thus,

The length of the rectangle is 2.5 m

The opposite sides of a parallelogram are congruent so a is 15.

3a+7a+2a=180 because the sum of the angles in the triangle BCD is 180 degrees.

3a+7a+2a=180

12a=180

a =180/12

a= 15

(I. e) 3a= 3(15)= 45

7a=7(15)=105

2a=2(15) =30

As a result, angle A=angle C (OPP. Angles of a Parallelogram are Equal) = A = B, D = A (OPP. angles of a parallelogram are equal)

In light of this, 7a=c = c = 105.

OPP sides in a parallelogram are parallel and equal, therefore AB is parallel to CD and BD is a transversal; as a result, angle d=2a (alternative internal angles are equal) translates to d=30.

Answer:

Step-by-step explanation:

This problem equals 35.4368, which has four decimal points

The standard normal curve, also known as the standard normal distribution or the z-distribution, is a specific probability distribution that follows a bell-shaped curve. The area under the standard normal curve to the right of z = 3 is approximately 0.0013.

For the area under the standard normal curve to the right of z = 3, we need to calculate the cumulative probability from z = 3 to positive infinity.

The standard normal distribution, also known as the z-distribution, has a mean of 0 and a standard deviation of 1. It is a symmetric bell-shaped curve that represents the distribution of standard scores or z-scores.

Using statistical tables or software, we can find the cumulative probability associated with z = 3, which represents the area under the curve to the left of z = 3.

The cumulative probability for z = 3 is approximately 0.9987.

For the area to the right of z = 3, we subtract the cumulative probability from 1.

Therefore, the area to the right of z = 3 is approximately 1 - 0.9987 = 0.0013.

In conclusion, the area under the standard normal curve to the right of z = 3 is approximately 0.0013.

This means that the probability of randomly selecting a value from the standard normal distribution that is greater than 3 is approximately 0.0013 or 0.13%.

Answer:

We will need to shade the region above f(x) and the region below the function g(x).

How to transform the graph into the solution set?

We have:

f(x) = x^2 - 1

g(x) = -x^2 + 4

Both of these are already graphed, and we want to transform it into:

y > f(x)

y ≤ g(x)

The first inequality means that we need to graph f(x) with a dashed line, because f(x) is not part of the solution, and then we shade all the region above f(x).

For the other inequality, we use a solid line (because the points on the line are solutions) and then we shade the part below the curve.
