An object's initial position

The initial velocity of an object

Step-by-step explanation:

That equation is used to solve for an object's final position.

The correct answer is False because, If the sample size is large enough (n greater than or equal to 30) the sampling distribution is approximately normal regardless of the shape of the population.

The sample fraction, often called the "p-hat", is the ratio of the number of sample successes to the size of the sample. The standard deviation of (p) decreases as the sample size n increases. This is because n is included in the denominator of the standard deviation formula. That is, (p has) has fewer variables for larger samples. The P-hat (must be a lowercase p with a caret (^) circumflex) indicates the percentage of the sample (this is the x-bar, the average of the samples).

A p-hat (proportion) sampling distribution is a collection of equal-sized repeated sample proportions drawn from the same population to represent it. According to the central limit theorem, the sampling distribution of p-hat is approximately normally distributed for large sample sizes.

Answer:

Completely Randomized Design would be the most appropriate experimental design for this scenario since it involves randomly assigning participants to different groups without any blocking factors present. Each subject represents an independent observation in the study, so treating them separately as units rather than blocks or paired observations makes sense. By comparing pre-treatment measures of sleep length against post-treatment measures taken after receiving Lunesta, researchers can evaluate its effectiveness in promoting better sleep patterns among those experiencing insomnia.

The most appropriate design for the described clinical trial of Lunesta drug, which measures sleep amounts before and after the treatment, is the Matched Pairs Design where each subject serves as their own control.

The design most appropriate for this experiment with the Lunesta drug should be the Matched Pairs Design. In a matched pairs design, each subject serves as their own control, which would apply here as sleep amounts are being measured for each subject before and after they have been treated with the drug. This is important because it means the experiment controls for any individual differences among participants. In other words, the same person's sleep is compared before and after taking the drug, so the effect of the drug is isolated from other factors that could potentially affect sleep.

Answer: 7*(x-4)

Step-by-step explanation: Since we have 28=7*4 we can write

7x-28=7*(x-4)

Each row has 3 chairs, and the total number of chairs is 17.

Let x be the number of chairs in each row.

According to the problem, Hue can form 3 rows of length x with 8 chairs left over.

This can be expressed as:

3x + 8 = n (where n is the total number of chairs)

Similarly, if she gets 10 more chairs, she can form 9 rows of length x, which can be expressed as:

9x = n + 10

Since both equations represent the same number of chairs, we can set them equal to each other:

3x + 8 = 9x - 10

Simplifying and solving for x, we get:

6x = 18

x = 3

Therefore, each row has 3 chairs, and the total number of chairs is:

n = 3x + 8

n = (3 x 3) + 8

n = 17 chairs

The unit vector with positive x-component that is orthogonal to both p(0) and p′(0) is \(v_u_n_i_t\) = v / ||v|| = ⟨-1,0,0⟩.

First, we need to find the vector that represents the position of the curve at t=0, which is p(0) = ⟨-1,0,0⟩.

Then we need to find the vector that represents the velocity of the curve at t=0, which is p'(t) = ⟨2t,2,4t⟩, so p'(0) = ⟨0,2,0⟩.

To find a unit vector that is orthogonal to both p(0) and p'(0), we can use the cross product:

v = p(0) x p'(0)

where "x" denotes the cross product. This will give us a vector that is perpendicular to both p(0) and p'(0), but it may not be a unit vector. To make it a unit vector, we need to divide by its magnitude:

\(v_u_n_i_t\) = v / ||v||

where "||v||" denotes the magnitude of v.

So let's calculate v:

v = p(0) x p'(0) = ⟨0,0,2⟩ x ⟨0,2,0⟩ = ⟨-4,0,0⟩

And the magnitude of v is:

||v|| = sqrt((-4)^2 + 0^2 + 0^2) = 4

So the unit vector that is orthogonal to both p(0) and p'(0) and has a positive x-component is:

\(v_u_n_i_t\) = v / ||v|| = ⟨-1,0,0⟩

The approximate number of price increases needed to maximize profit is 2.5

From the question, we have the following parameters that can be used in our computation:

x = number of price increases

y = Profit

Also from the question, we have

Begins at (0, 50)

Increases to (2.5, 81.25)

Decrease through (6.531, 0)

This means that

Maximum = (2.5, 81.25)

Recall that

Step-by-step explanation:

The set of vectors in R2 whose span is set s is : {[ -5 s-4 s][ 1 0], [ -5 s-4 s][ 0 1]}, for the given set of vector in R2.

Given set s of all vectors of the form [-5s, -4s].

To find a set of vectors in R2 whose span is s.

Such vectors can be obtained by applying matrix multiplication, such that set of vectors in R2 must look like[x, y] which can be transformed into the vectors of set s using matrix multiplication

[ -5 s-4 s][ x y]

Now, expanding this, the above matrix multiplication gives

-5sx - 4sy

So we can obtain a vector in set s with linear combination of the vector

[ -5 s-4 s][ 1 0]

gives[-5s, 0]

which is a vector in set s

Also, the vector[ -5 s-4 s][ 0 1] gives [-4s, 0]which is a vector in set s.

Now, any vector in set s can be represented as linear combination of above two vectors.

So the set of vectors in R2 whose span is set s is

{[ -5 s-4 s][ 1 0], [ -5 s-4 s][ 0 1]}

A set of vectors in R2 whose span is S is {[-5, -4], [0, 0]}.

To find a set of vectors in R2 whose span is S, we need to express the given set S in terms of a basis for R2.
The given set S is defined as the set of all vectors of the form [-5s, -4s].
In order to express this set in terms of a basis for R2, we need to find two vectors that span S. Let's call these vectors v1 and v2.
To find v1, we can set s = 1 and calculate:
v1 = [-5(1), -4(1)] = [-5, -4]
To find v2, we can set s = 0 and calculate:
v2 = [-5(0), -4(0)] = [0, 0]
Now we have two vectors, v1 = [-5, -4] and v2 = [0, 0], which form a basis for S. These vectors span S because any vector in S can be expressed as a linear combination of v1 and v2.
