H0: The distribution of lunch preferences is 70% cafeteria, 10% hut, 10% taco wagon, and 10% pizza.

Ha: The distribution of lunch preferences is not 70% cafeteria, 10% hut, 10% taco wagon, and 10% pizza place.

In hypothesis testing, we have a null hypothesis (H0) and an alternative hypothesis (Ha). The null hypothesis represents the claim or assumption we want to test, while the alternative hypothesis represents the opposite or alternative claim.

In this case, the null hypothesis (H0) states that the distribution of lunch preferences is 70% cafeteria, 10% hut, 10% taco wagon, and 10% pizza place. The alternative hypothesis (Ha) states that the distribution of lunch preferences is not 70% cafeteria, 10% hut, 10% taco wagon, and 10% pizza place.

To test these hypotheses, a random sample of 150 students is selected, and their lunch preferences are recorded. The goal is to determine if the observed distribution of lunch preferences in the sample provides enough evidence to reject the null hypothesis in favor of the alternative hypothesis.

What exactly is a p-value?

Answer: the one on the top right

Step-by-step explanation:

With proper conclusion, we can say that the probability that Jones would get at least 20,000 additional miles out of the car is very low, almost negligible.

To find the probability that Jones would get at least 20,000 additional miles out of the car, we need to consider the distribution of the random variable.

In this case, the random variable represents the additional miles Jones would get out of the car, given that Smith claims it has been driven only 10,000 miles.
Given that the parameter is 20, we can assume that the random variable follows a Poisson distribution with parameter λ = 20.

The Poisson distribution is commonly used to model the number of events occurring in a fixed interval of time or space.

To find the probability that Jones would get at least 20,000 additional miles out of the car, we can use the cumulative distribution function (CDF) of the Poisson distribution. The CDF gives the probability that the random variable is less than or equal to a certain value. In this case, we want to find the probability that the random variable is greater than or equal to 20,000.

Using the Poisson CDF, we can calculate this probability. However, since the parameter is 20, the probability of getting at least 20,000 additional miles out of the car would be extremely low. It would be close to zero.

Therefore, with proper conclusion, we can say that the probability that Jones would get at least 20,000 additional miles out of the car is very low, almost negligible.

Step-by-step explanation:

9. H is a subspace of R3 as it contains a 2s vector [0, 2s, 0].

10. H is a subspace of R3 as it consists of the zero vector [0, 0, 0].

11. W is a subspace of R3 as it is spanned by the vectors [1,0,0] and [1,1,0].

12.W is a subspace of R4 as it is spanned by the vectors [1,2,0,0] and [0,-1,4,0].

9. To find a 2s vector v in R3 such that H is a subspace of R3, we can choose v = [0, 2s, 0]. This vector satisfies the condition of H being a subspace since it is of the form 2s, and any scalar multiple of v will also be of the form 2s, which is within H. Therefore, H is a subspace of R3.

0. Let H be the set of all vectors of the form [0, 0, 0]. To show that H is a subspace of R3, we can use the method from Exercise 9. By choosing v = [0, 0, 0],

we can see that H is closed under scalar multiplication and addition, as any scalar multiple or sum of the zero vector will still result in the zero vector. Therefore, H is a subspace of R3.

11. Let W be the set of all vectors of the form [b, c, 0], where b and c are arbitrary. To show that W is a subspace of R3, we need to find vectors u and v such that W is spanned by (u, v).

We can choose u = [1, 0, 0] and v = [0, 1, 0]. Any vector in W can be expressed as a linear combination of u and v, and therefore W is spanned by (u, v). This shows that W is a subspace of R3.

12. Let W be the set of all vectors of the form [s, 2s - t, 4t] in R4. To show that W is a subspace of R4, we can use the method from Exercise 11. By choosing u = [1, 2, 0, 0] and v = [0, -1, 4, 0],

we can observe that any vector in W can be expressed as a linear combination of u and v. Hence, W is spanned by (u, v), indicating that W is a subspace of R4.

Press fit is calculated by determining the required force to assemble two cylindrical parts, using the interference between them and their material properties.

Press fit is calculated by determining the amount of interference between two cylindrical parts and their material properties. The interference is the difference between the diameter of the shaft (male part) and the diameter of the hole (female part). The required force to assemble the parts is then calculated using the material properties of both parts and the amount of interference. The interference is typically expressed as a percentage of the shaft diameter, and the required force is expressed in pounds or newtons.

Calculating the press fit is important for ensuring that the parts are securely and correctly assembled, and for preventing excessive stress or deformation in either part. Press fit calculations are commonly used in mechanical engineering and manufacturing applications.

a ratio is a special fraction.

it is a simplified form of the rehab of both fractions of both types of items in the bag.

the sum of numerator and denominator gives us a relative number of coin units.

each unit has the exact same number of coins (but only of the corresponding type).

99 + 55 = 154 coin units.

1.

so, the fraction of coins being dimes is 55/154.

the fraction of coins being quarters is 99/154.

55 × f = 99

f = 99/55 = 1.8

Answer:

4sqrt(2) cm

a^2 + b^2 = c^2

sqrt(32) = c

c = 4sqrt(2)

The two other roots of p(x) are 8 - 4√31 and 8 + 4√31. The smaller root is 8 - 4√31 and the larger root is 8 + 4√31. We can calculate it in the following manner.

We know that the sum of the roots of a polynomial with real coefficients is equal to the negative of the coefficient of the second-to-last term divided by the coefficient of the leading term.

Therefore, the sum of the roots of p(x) is:

1 + 7 + r1 + r2 = -(-24)/1 = 24

where r1 and r2 are the two other roots of the polynomial. We can rewrite this equation as:

r1 + r2 = 16

We also know that the product of the roots of a polynomial is equal to the constant term divided by the coefficient of the leading term. Therefore, the product of the roots of p(x) is:

1 x 7 x r1 x r2 = 7/1 = 7

We can rewrite this equation as:

r1 x r2 = 7/7 = 1

Now, we can use this information to write a quadratic factor of p(x) that has r1 and r2 as its roots. We know that:

(x - r1)(x - r2) = x^2 - (r1 + r2)x + r1r2

Substituting in the values we know, we get:

(x - r1)(x - r2) = x^2 - 16x + 1

Therefore, we have:

p(x) = (x^2 - 16x + 1)(x^2 - 16x + 238)

The roots of the second quadratic factor can be found using the quadratic formula:

x = (16 ± √(16^2 - 4(1)(238))) / 2

x = 8 ± √(496)

The smaller root is 8 - √(496), which can be simplified to:

8 - √(496) = 8 - 4√31

The larger root is 8 + √(496), which can be simplified to:

8 + √(496) = 8 + 4√31

Therefore, the two other roots of p(x) are 8 - 4√31 and 8 + 4√31. The smaller root is 8 - 4√31 and the larger root is 8 + 4√31.

Answer:

Step-by-step explanation:

The formulas for cos(6θ) and sin(6θ) using de Moivre's theorem are:

cos(6θ) = Re[(cosθ + isinθ)^6]

sin(6θ) = Im[(cosθ + isinθ)^6]

To find the formulas for cos(6θ) and sin(6θ) using de Moivre's theorem, we can start by expressing (cosθ + isinθ) raised to the power of 6. According to de Moivre's theorem, this can be written as (cos(6θ) + isin(6θ)).

Expanding (cosθ + isinθ)^6 using the binomial theorem, we get:

(cosθ + isinθ)^6 = C(6, 0)(cosθ)^6(isinθ)^0 + C(6, 1)(cosθ)^5(isinθ)^1 + C(6, 2)(cosθ)^4(isinθ)^2 + C(6, 3)(cosθ)^3(isinθ)^3 + C(6, 4)(cosθ)^2(isinθ)^4 + C(6, 5)(cosθ)^1(isinθ)^5 + C(6, 6)(cosθ)^0(isinθ)^6

Simplifying this expression, we can calculate each term separately. The terms with odd powers of isinθ will be imaginary and will contribute to sin(6θ), while the terms with even powers of isinθ will be real and will contribute to cos(6θ). After evaluating the terms and combining like terms, we obtain the formulas for cos(6θ) and sin(6θ).

Answer:

Step-by-step explanation:

The system of equations is 5x + 6y = 34 and 4x + 6y = 32

A small page can fit 2 photographs, and a large one can fit 4 photographs.

Let the number of photographs on small pages be x and number of large pages be y

Emily plans to assemble 5 small pages and 6 large pages and brought a total of 34 photographs to use.

5x + 6y = 34....equation 1

Carrie brought 32 photographs, which is enough to assemble 4 small pages and 6 large pages.

4x + 6y = 32...,equation 2

Subtracting equation 2 from equation 1

5x + 6y - (4x + 6y) = 34 - 32

5x - 4x + 6y - 6y = 2

x = 2

5x + 6y = 34.

5(2) + 6y = 34

10 + 6y = 34

6y = 24

y = 4

Therefore, a small page can fit 2 photographs, and a large one can fit 4 photographs.
