there is no inner product on R² such that under this inner product, the norm of a vector (x,y) is [x] + [y].

We can disprove the given statement by finding a counterexample.

A counterexample will prove that the statement is false. Here is the counterexample:Suppose there exists an inner product on R² such that under this inner product, the norm of a vector (x,y) is [x] + [y].

Now, let's consider two vectors in R² such that u = (1, 0) and v = (0, 1).Then the inner product of these two vectors will be:⟨u, v⟩ = ⟨(1, 0), (0, 1)⟩= 1*0 + 0*1 = 0

Now, if there exists an inner product such that ||(x,y)|| = [x] + [y], t

hen by the properties of inner products, we must have:||u + v||² = ||u||² + ||v||²This is known as the Pythagorean property of inner products.

But, as we have shown, this property does not hold for the given inner product.So, we have a contradiction, and hence we can conclude that there is no inner product on R² such that under this inner product, the norm of a vector (x,y) is [x] + [y]. Hence, we have disproved the given statement.

The probability that exactly n of the collection of n spins will point up is given by the Binomial distribution. The Binomial distribution is a discrete probability distribution that models the number of successes (x) in a given number of trials (n) with a fixed probability of success (p) on each trial.

In this case, we have n trials, with a fixed probability of success of 0.5 (since each spin can point up or down with equal probability). The number of successes we're interested in is n. Thus, the probability of n successes is given by:P(X = n) = (nCn)(0.5)^n = 0.5^nwhere nCn is the number of ways to choose n items from n items, which is 1.Approximation for large n:When n is large, we can use the normal approximation to the Binomial distribution.

Specifically, we use the Normal distribution with mean np and variance np(1-p). In this case, p = 0.5, so the mean and variance are both (0.5)n. Therefore, the probability of n successes is approximately:P(X = n) ≈ φ(x) = (1/σ√2π)exp[-(x-μ)^2/2σ^2]where μ = np = (0.5)n and σ^2 = np(1-p) = (0.5)n(0.5) = (0.25)n.

Plugging these values in, we get:P(X = n) ≈ φ(x) = (1/σ√2π)exp[-(n/2n)^2/2(0.25)n] = (1/σ√2π)exp[-(1/8n)] = (1/√2πn)exp[-(1/8n)]Note that for the large n approximation to be valid, we require np and n(1-p) to be at least 10. In this case, np = (0.5)n and n(1-p) = (0.5)n, so this condition is satisfied for any n.

Step-by-step explanation:

The decision between the two cities involves tradeoffs: the first city offers a wide range of class sizes but a smaller sample, while the second city has a larger sample but a narrower class size range.

The decision of which city to choose for the study involves tradeoffs. The first city allows for a wide range of class sizes, providing a comprehensive analysis of the relationship between class size and academic performance. However, the smaller sample size limits generalizability.



The second city offers a larger sample size, increasing generalizability, but with a narrower range of class sizes. Researchers should consider their specific research objectives, available resources, and constraints. If the goal is to assess the impact of extreme variations in class size, the first city is suitable. If obtaining highly generalizable results is paramount, the second city, despite the narrower range, should be chosen.



Therefore, The decision between the two cities involves tradeoffs: the first city offers a wide range of class sizes but a smaller sample, while the second city has a larger sample but a narrower class size range.

Answer:

13. Bestie literally 9+4

Answer:When solving a question like "What number is 4 less than 9?", take a close look at what it is really asking.

You have the number 9 and you are looking for a number that is 4 less than 9. In other words, if you have 9 and take away 4, then how many do you have?

You guessed it! This is a subtraction problem. 9 is the minuend and 4 is subtrahend and the answer we are looking for is the difference.

Therefore, to solve "What number is 4 less than 9?", you subtract 4 from 9 like so:

C) The two stores never charge the same rate as per the cost expression of store A and store B.

The each expression of store A and store B represent the total cost charged by them based on the number of items bought. The mentioned expressions will be equated when assuming their total cost to be same. Thus, equating the the expressions.

20x - 8 = 5 (4x + 4)

Performing multiplication on Right Hand Side of the equation

20x - 8 = 20x + 20

Since 20x is present on both the sides, it will be cancelled. The remaining expression will be :

8 = 20, which is a false case as 8 is not equal to 20.

Thus, the equation has no solution and hence, the two stores will never charge the same rate, no matter how many items are bought.

Explanation:

We can model the situation as:

Since P and R have a y-coordinate equal to 0, Q has a y-coordinate 0

Now, to calculate the x-coordinate, we can formulate the following equations:

Rx - Px = 3a

Qx - Px = 2a

Where Rx is the x-coordinate of R, Px is the x-coordinate of P and Qx is the x-coordinate of Q. So, replacing the values:

-12 - 0 = 3a

x - 0 = 2a

Now, solving for a, we get:

-12 - 0 = 3a

-12 = 3a

-12/3 = a

-4 = a

Replacing on the second equation, we get:

x - 0 = 2a

x = 2a

x = 2*(-4)

x = -8

Therefore, the coordinates of Q are (-8, 0)

Answer: (-8, 0)

The entire circle has an area of pi * r^2

Area = 3.14 * 10^2

Area = 314 cm^2

But that is the whole circle. What is shaded is 1/4 of the circle which 314/4

which = 78.5 cm^2

Answer: A

Answer:

A) 78.5 cm^2

Step-by-step explanation:

1. To find the shaded part of the circle (1/4), we can use a formula similar to the one we use to find the area of a whole circle, but in this case, for the 1/4 part that's shaded: \(\frac{1}{4} \pi r^2\). Keep in mind that pi is approximated to 3.14.

2. (Solving)

Step 1: Plug in the values.

Step 2: Simplify.

Therefore, the answer is A) 78.5 cm^2.

To establish whether findings from a sample may be extrapolated to the entire population, we use inferential statistics.

A population is the total group about which you want to reach conclusions. A sample is the specific group from which you will collect data. Always, the sample size is less than the whole population. The term "population" in research rarely refers to people. Using an office as an example, all of the employees would represent the Population, and all of the managers would represent the Sample. To create a comparison, picture your population as an ocean, and your sample as an aquarium.

Inferential statistics is a branch of statistics that uses data to draw inferences and generalizations about a certain situation or fact.

The matrix multiplication EC + BH yields the result [1 4m; -8 + n -2p; 0 -2]. This means that the resulting matrix is a 3x2 matrix, where the first row contains the values 1 and 4m, the second row contains the values -8 + n and -2p, and the third row contains the values 0 and -2.

To obtain the result, we perform matrix addition by adding the corresponding elements of matrices EC and BH. Each element in the resulting matrix is the sum of the corresponding elements in EC and BH. The resulting matrix represents the combined effect of the two matrices on each element.

In this case, the resulting matrix shows the sum of the elements from matrices EC and BH. Each element is calculated by adding the corresponding elements in EC and BH. For example, the element in the first row and first column is obtained by adding -3 and 4 from EC and BH, respectively.

The diameter of Earth in kilometers is approximately 12,682 km, making option D the correct answer.

To convert the diameter of Earth from miles to kilometers, we can multiply the given diameter in miles by the conversion factor of 1.6 kilometers per mile.

Given that Earth's diameter is 7,926 miles, we can calculate its diameter in kilometers as follows:

Diameter in kilometers = Diameter in miles × Conversion factor

Diameter in kilometers = 7,926 miles × 1.6 kilometers/mile

Diameter in kilometers = 12,681.6 kilometers

Rounding this value to the nearest whole number, we get 12,682 kilometers.

Therefore, the correct answer is option D: 12,682 km.

Option A: 49,553 km is not the correct answer. It is not consistent with the given diameter of Earth.

Option B: 120,586 km is also not the correct answer. It is not consistent with the given diameter of Earth.

Option C: 1,392,650 km is significantly larger than the actual diameter of Earth and is not a plausible value.

In conclusion, the diameter of Earth in kilometers is approximately 12,682 km, making option D the correct answer.
