The correct answer is a. states that the treatment has no effect.

The null hypothesis is a statement about a population that we assume to be true until we have evidence to the contrary. In statistics, the null hypothesis is often used to test the effect of a treatment or intervention on a population. The null hypothesis typically states that there is no difference between the treatment group and the control group, or that the treatment has no effect on the population. This is denoted by the symbol H0, not H1 as stated in option b. Option c is also incorrect, as the null hypothesis is typically stated in terms of population parameters, not sample statistics. Therefore, the correct answer is option a.

Answer:

6

Step-by-step explanation:

4 1/2 divided by 3/4 is 6. so 6 pieces

The greatest number of 3/4 foot pieces that Annie can cut from the rope

is 6.

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Annie has 4 1/2 feet of rope.

Therefore, The greatest number of 3/4 foot pieces Annie can cut can be obtained by dividing the length of the total rope by the length of each piece which is,

= (4 1/2)/(3/4).

= (9/2)×(4/3).

= 36/6.

= 6.

So, 6 pieces are possible.

Step-by-step explanation:

Diameter of cone = 24 units

Radius of cone (r) = 24/2 = 12 units

Height of cone (h) = 28 units

\(V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ 3} \times 3.14 \times {(12)}^{2} \times 28 \\ \\ = \frac{1}{3} \times 3.14 \times 144 \times 28 \\ \\ = 3.14 \times 1,344 \\ \\ = 4,220.16\: {units}^{3} \)

The true statement is that you can predict whether the product will be less than or greater either of the factors, and the prediction is that the product will be less than either of the factors

The statement is given as:

Predict whether the product of two decimal numbers less than 1 will be less than or greater either of the factors

Let the product equation be represented as:

x * y = z

Where

x and y are decimal numbers less than 1

So, we have

x < 1 and y < 1

Example of such numbers are:

x = 0.1 and y = 0.2

So, we have:

x * y = 0.1 * 0.2

Evaluate the product

x * y = 0.02

The decimal number 0.02 is less than 0.1 and 0.2

This is the same for all decimal numbers with the given characteristics

Hence, the true statement is that you can predict whether the product will be less than or greater either of the factors, and the prediction is that the product will be less than either of the factors

Step-by-step explanation:

The dimensions of the box that will have the greatest volume are:

Length and width of the base: 2√3 feet

Height: h = (36 - x^2) / 8x = (√3)/2 feet

Let the length and width of the base be x, and let the height be h.

The surface area of the top is x^2, and the surface area of the remaining four sides is \(2(xh + xh) = 4xh\).

The cost of the top is \(x^2\), and the cost of the remaining four sides is \(2(4xh) = 8xh\). Therefore, the total cost is:

\(C(x,h) = x^2 + 8xh\)

We know that the total cost is $36, so we have:

\(x^2 + 8xh = 36\)

Solving for h, we get:

\(h = (36 - x^2) / 8x\)

The volume of the box is given by:

\(V(x,h) = x^2h\)

Substituting h in terms of x, we get:

\(V(x) = x^2 ((36 - x^2) / 8x)\)

Simplifying, we get:

\(V(x) = (1/8) x (36x - x^3)\)

To find the dimensions of the box that will have the greatest volume, we need to find the value of x that maximizes V(x). We can do this by taking the derivative of V(x) with respect to x, setting it equal to 0, and solving for x:

\(V'(x) = (1/8) (36 - 3x^2) = 0\)

Solving for x, we get:

x = 2√3

Therefore, the dimensions of the box that will have the greatest volume are:

Length and width of the base: 2√3 feet

Height: \(h = (36 - x^2) / 8x\) = (√3)/2 feet

The volume of the box is:

\(V = x^2h\)= (2√3)^2 ((√3)/2) = 9√3 cubic feet

Note: To confirm that this value represents the maximum volume, we can check that V''(x) < 0, which indicates a maximum point. We have:

\(V''(x) = (1/8) (-6x) = -3x/4\)

At x = 2√3, V''(x) = -3(2√3)/4 = -3√3/2 < 0, so this is indeed a maximum point.

In summary, we are given a surface S defined by the equation z = f(x, y) and asked to evaluate the surface integral over the lower side of the part of S between the planes z = 0 and z = 2. The integrand is given as [(z [(z² + x)dy / dz - zdx / dy].

To evaluate this surface integral, we need to parameterize the surface S and compute the appropriate limits of integration. The given equation z = f(x, y) can be rewritten as z = x² + y². This represents a paraboloid centered at the origin with a vertex at z = 0 and opening upwards.

The explanation would involve parameterizing the surface S by introducing suitable parameters, such as spherical coordinates or cylindrical coordinates, depending on the symmetry of the surface. We would then determine the appropriate limits of integration based on the given boundaries z = 0 and z = 2.

Once the surface S is parameterized and the limits of integration are determined, we would substitute the parameterization and limits into the integrand and perform the necessary computations to evaluate the surface integral. The result will be a numerical value representing the evaluated surface integral over the specified region of the surface S.

let's multiply both sides of the congruence equation by r, which is a positive integer. we need to show that g is a homomorphism. That is, for any cosets [a]n and [b]n, g([a]n + [b]n) = g([a]n) + g([b]n).

Let's assume [a]n = [b]n. This means that a and b are congruent modulo n, which can be written as a ≡ b (mod n).  Since k divides n (k∣n), we can write n = k * m for some positive integer m. Substituting this into the congruence equation, we get a ≡ b (mod k * m). Now, let's multiply both sides of the congruence equation by r, which is a positive integer.

This gives us ra ≡ rb (mod k * m).

Since k * m = n, we can rewrite this as ra ≡ rb (mod n).
Therefore, we have shown that if [a]n = [b]n,

then [ra]k = [rb]k, which proves that the function f is well-defined.
To prove that Zn / ⟨k⟩ ≅ Zk, we need to show that the set of cosets Zn / ⟨k⟩ is isomorphic to the set Zk.

The probability that a student, chosen at random, does not study chemistry is 20/41.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. For an experiment having 'n' number of outcomes, the number of favorable outcomes can be denoted by x. The formula to calculate the probability of an event is as follows.

Probability(Event) = Favorable Outcomes/Total Outcomes = x/n

Here, Total number of student = 41

         Student who does not study chemistry = 20

So, the probability = favorable outcome / total outcomes

             P(not studying chemistry) = 20 / 41

Thus, The probability that a student, chosen at random, does not study chemistry is 20/41.

a = 3h + 2.50b

Step-by-step explanation:

Greg picks apples to make money over the summer. He earns $3 an hour plus $2.50 for each bushel he picks. Write a formula that will help Greg determine how much money he will earn in one week.

Let

a = Total amount earned

h = Hours worked in one week

b = Number of bushels picked

Solution:

Amount earned per hour = $3

Amount earned per bushel picked = $2.50

Total amount earned = (Amount earned per hour) ( Hours worked in one week) + (Amount earned per bushel picked) (Number of bushels picked)

a = 3*h + 2.50*b

= 3h + 2.50b

a = 3h + 2.50b

Answer:

Let x be the shorter side of the rectangular house. Since the length of the house is two-and-a-half times its width, we can write this as 2.5x. The area of a rectangle is given by the formula length * width, so the area of the rectangular house in terms of x is 2.5x * x = 2.5x^2. This is the expression for the area of the rectangular house in terms of the shorter side x.

Answer:

\(2.5x^2\)

Step-by-step explanation:

Let x be the shorter side of the rectangle, which is also its width (w), so:

\(w=x\)

Given that the length of the rectangle is two-and-a-half times its width, this means the length (l) can be expressed as:

\(l=2.5x\)

The area of a rectangle (A) is the product of its length (l) and width (w):

\(A =l \cdot w\)

Substitute the expressions for length and width into the formula for area:

\(A=2.5x \cdot x\)

Simplify this expression:

\(A=2.5x^2\)

Therefore, the expression for the area of the rectangle in terms of x is:

\(\Large\boxed{\boxed{2.5x^2}}\)

Simplifying x² - 5x - 16:

To factorize this quadratic expression, we look for two numbers whose product is equal to -16 and whose sum is equal to -5. The numbers are -8 and 2.

Therefore, x² - 5x - 16 can be written as (x - 8)(x + 2).

Simplifying 6an² - 3b²n²:

To simplify this expression, we can factor out the common term n² from both terms:

6an² - 3b²n² = n²(6a - 3b²).

Simplifying 4x² - 4xy + y²:

This expression represents a perfect square trinomial, which can be factored as (2x - y)².

Simplifying n + 1 - n³ - n²:

Combining like terms, we get -n³ - n² + n + 1 = -(n³ + n² - n - 1).

Simplifying 17x³y⁴z⁶:

To simplify this expression, we can divide each exponent by 2 to simplify it as much as possible:

17x³y⁴z⁶ = (x²y²z³)².

Simplifying 12a²b³:
