how is the size of a sample related to the spread of the sampling distribution

Answer: The bag of seeds covers 5656 square feet and is 1/3 pound. To find how many square feet the seeds cover per pound, we can divide the total coverage by the weight of the bag.

Formula: Coverage per pound = Total coverage/weight of the bag

5656 / (1/3) = 5656*3 = 16,968 square feet per pound.

6750 [tex]{}[/tex]                20000

Based on the above data, using the Polynomial trendline option of Order 2, in MS Excel, the quadratic regression equation, obtained using the Display Equation on chart option is; y = -0.004·x² + 34.637·x -29,864

The function, f(x) = -0.004·x² + 34.637·x -29,864, indicates that at x = 0, which is the point where 0 units have produced, we get;

Initial Profits = f(0) = -0.004 × 0² + 34.637 × 0 -29,864 = -29,864

The best choice for a deep spot to take a swim is to go to a place in the river where the cross-sectional area is larger, and the water flows slower.

If you are looking for a deep spot to take a swim in a local river, the best choice is to go where the water flows slowly. The speed of the water is determined by the formula:

v=Q/A,

where v is the speed of the water, Q is the discharge rate, and A is the cross-sectional area of the river. As Q is constant for the same river, a slower water flow can be achieved by increasing A, which is the cross-sectional area of the river. Therefore, the best choice for a deep spot to take a swim is to go to a place in the river where the cross-sectional area is larger, and the water flows slower.

A 5th degree polynomial have five complex roots. This means that the polynomial can be written as the product of five linear or quadratic polynomials.

The general formula to calculate the roots of a 5th degree polynomial is:

[tex]x^5 + ax^4 + bx^3 + cx^2 + dx + e = 0[/tex]

The roots of the polynomial can be found by solving the following equation:

[tex]x^4 + (a - x)x^3 + (b - a x + x^2)x^2 + (c - bx + ax^2 - x^3)x + (d - cx + bx^2 - ax^3 + x^4) = 0[/tex]

To calculate the roots of the polynomial, we need to solve the quartic equation, which can be done by using the quadratic formula. Then, we can use the solutions of the quartic equation to find the roots of the 5th degree polynomial.

For example, if we have the polynomial x^5 + 2x^4 + 3x^3 + 4x^2 + 5x + 6 = 0, then the roots can be calculated as follows:

The width of the bookcase is 6 feet and height is 4 feet if the carpenter expects to use 28 feet of lumber to make it.

Let w = the width and h = the height of the bookcase. The width of the lumber you are using is not given.

Also, Let the height is x.

and, the width is 3x -14.

Since, we stated that this equals 28 feet and also that w = 3h - 14, we can insert this into the equation and use it to solve for h:

Now,

The total amount of lumber used to make the bookcase is:

L = 4w + 2h             -------------------------- (1)

Now Putting Width and height in the Equation (1):

⇒ 28 = 4(3h - 14) + 2h

⇒ 28 = 12h - 56 + 2h

⇒ 28 = 14h - 56

⇒ 84 = 14h

⇒ h = 84/14

      = 6 feet

Putting the value of height, h= 6 feet in

w = 3x -14

⇒ w = 3(6) - 14 = 4.

Area = 3 [tex]\sqrt{3}[/tex]/2 * [tex]side^{2}[/tex]

Each internal angle in an irregular hexagon can be greater than or less than 120 degrees, and the sides are uneven in length.

In our question it is given that the ratio of the area of two similar hexagons is 5:2. This indicates that the sides' square ratio is 5: 2.

Let x represent the corresponding side in the opposite hexagon.

Then, [tex]25^{2}[/tex] : [tex]x^{2}[/tex] = 5:2

area: 576 cm ^2

perimeter: (48 + 24π) cm

Step-by-step explanation:

the semicircle taken out of the square (the white area) is equal to the semicircle added to the left of it. thus, we just have the area of a square. we know this because both have the same diameter and are semicircles. thus, our area is 24^2 = 576 cm ^2

for perimeter:

top: 24 cm

bottom: 24 cm

right: this is equal to half the circumference of a circle. this is because we know it's a semicircle taken out. circumference = πd = 24 * π. divide this by 2 to get 12π.

left: this is also equal to half the circumference of a circle = 12π

The hybrid factor is f(w) Equals 50w + 25 according to the preceding statement. The hybrid value is measured in units of f (flowers) and w (weeks), etc. 30 weeks of Part A's synthesis function equal 1525.

A task is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is just the input value, we would state that y is a mathematical function

Given that:

f(s) = 2s + 25

s(w) = 25w

The following combination function is used to determine how many flowers will blossom over the course of w weeks: f(w)

f(s) = 2s + 25

Replace s with s(w)

f(s(w)) = 2(s(w)) + 25

Substitute s(w) = 25w

f(s(w)) = 2(25w) + 25

f(s(w)) = 50w + 25

Hence,

f(w) = 50w + 25

Flowers are used as the units of measurement for f(w).

30 weeks of flowers translates to:

w = 30

So, we have:

f(30) = 50*30+25

f(30) = 1525

Thus, there will be 1525 blossoms throughout the course of 30 weeks.

Option C connects the motion of the trumpet with Newton's first law of motion.  The trumpet starts moving because a net force overcomes the trumpet's inertia.

According to Newton's first law of motion, a body won't begin to move unless and until an outside force acts on it. When anything starts moving, it won't stop or vary its speed unless another force acts on it. The law of inertia is another name for the first law of motion.

Given, The concert band's trumpet player is Andrew. Until it is time for him to play, he keeps the instrument still at his side. He positions the trumpet next to his mouth and begins to play afterward.

First of all, there are no movements, no acceleration, and no velocity for the trumpet. Newton's first law of motion, which states that an object at rest stays at rest and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force, explains why the trumpet is in this state. The trumpet continues to move at zero velocity since there is no net force exerted on it.

The trumpet is then moved by Andrew. It indicates that Andrew pushed the trumpet with vigor. It caused the body to transition from the resting condition to the moving state.

Finally, we can draw the conclusion that Trumpet will remain at rest unless Andrew applies a net force that is different from zero in accordance with Newton's first law of motion.

= 41% (rounded to the nearest whole percent)

Elijah's debt-to-credit ratio is a measure of how much of his available credit he has used. It is calculated by dividing his total debt by his total credit limit. In this case, Elijah currently owes a total of $2,127.50 on his revolving credit account, and his total credit limit is $5,750.00. When we divide his debit of $2,127.50 by his total credit limit of $5,750.00, we get a debt-to-credit ratio of 0.37. This is equivalent to 37%.

We can use the formula A = P(1 + r/n)^(nt) to find out how long it takes for William's money to triple, where A is the final amount, P is the principal, r is the interest rate, t is the time in years and n is the number of times the interest is compounded per year.

A = P(1 + r/n)^(nt) = 550(1 + 0.02/12)^(12*t) = 3P

Solving for t we get

t = (ln(3)/ln(1+0.02/12))/12 = 49.41

For Violet's account, using the formula A=Pe^(rt) where A is the final amount, P is the principal, r is the interest rate, t is the time in years, we get:

t = ln(3) / (2 * e^-2) = 49.41

Therefore, it will take approximately 49.41 years for William's money to triple, and 49.41 years for Violet's money to triple.

So the difference in time is 0.
