We need to first determine how many totally odd counting numbers there are between 1 and 9. The answer is 250.

It is an integer that is not divisible by two and therefore has a remainder of 1 when divided by two. It is also referred to as an odd number, an odd integer, or an uneven number.

For this, let us consider all the digits from 1 to 9, and their respective sums.

Digit: 1 Sum: 1 (odd)

Digit: 3 Sum: 3 (odd)

Digit: 5 Sum: 5 (odd)

Digit: 7 Sum: 7 (odd)

Digit: 9 Sum: 9 (odd)

Since all the digits between 1 and 9 and their respective sums are all odd, it means that any counting number less than 10 that is composed of only these digits would be totally odd. This means that there are 5 totally odd counting numbers less than 10, i.e., 1, 3, 5, 7 and 9.

Now, since any counting number less than 1000 can be composed of any combination of these 5 digits, the total number of totally odd counting numbers less than 1000 can be calculated by multiplying the number of digits (5) by the number of combinations of those digits (999). The result of this calculation is 250, which is the answer to the question.

a polynomial of degree 5 with integer coefficients that has zeros -2, √3i, √2i, and y-intercept of 36 is

[tex]f(x) = x^{5} + 5x^{4} + 13x^{3} + 21x^{2} - 6x + 84[/tex]

Let us begin by writing the polynomial factors using the supplied zeros:

Because -2 is a zero, the polynomial has a component of (x + 2).

Because [tex]\sqrt{ 3i }[/tex] is a zero, its conjugate -[tex]\sqrt{ 3i }[/tex] is likewise a zero, implying that the polynomial has a component of (x - [tex]\sqrt{3i}[/tex])(x + [tex]\sqrt{3i}[/tex]) = (x2 + 3).

Similarly, because [tex]\sqrt{2i}[/tex] is a zero, its conjugate -[tex]\sqrt{ 2i }[/tex] is also a zero, implying that the polynomial has a component of (x - [tex]\sqrt{ 2i }[/tex])(x + [tex]\sqrt{ 2i }[/tex]) = (x2 + 2).

Finally, we know that the y-intercept is 36, which means that the polynomial's constant term is 36 when x=0.

When we add these components together, we get:

[tex]f(x) = (x + 2)(x^2 + 3)(x^2 + 2) + 36[/tex]

Extending on this, we get:

b) The number of squares that will fit on the land is 61773.

Explain square

A square is a geometric shape with four sides of equal length and four right angles. It is a type of rectangle, but all of its sides are the same length. Squares are used in mathematics to represent and calculate areas and volumes, and they also have applications in architecture and art.

According to the given information

(a) To find the area of the largest squares that will fit on the land, we need to find the greatest common divisor (GCD) of the dimensions 735 and 756, and then square it.

To find the GCD, we can use the Euclidean algorithm:

GCD(735, 756) = GCD(735, 756 - 735) = GCD(735, 21) = GCD(21, 735 - 21 * 35) = GCD(21, 210) = GCD(21, 210 - 21 * 10) = GCD(21, 90) = GCD(21, 90 - 21 * 4) = GCD(21, 6) = GCD(6, 21 - 6 * 3) = GCD(6, 3) = 3

Therefore, the GCD of 735 and 756 is 3. The largest squares that will fit on the land will have sides of length 3 meters. The area of each square is 3 * 3 = 9 square meters.

(b) To find how many squares will fit on the land, we need to divide the total area of the land by the area of each square. The total area of the land is:

735 * 756 = 555960 square meters

The area of each square is 9 square meters, as we found in part (a). Therefore, the number of squares that will fit on the land is:

555960 / 9 = 61773.333...

Since we can't have a fractional number of squares, we need to round down to the nearest integer. Therefore, the number of squares that will fit on the land is 61773.

If  an ethanol railroad tariff is a fee charged for shipments of ethanol on public railroads. The  probability is:  84.6%.

In this case, we have:

Population standard deviation (σ): $1200

Sample size (n): 400

Margin of error (E): $80

The standard deviation of the sample mean can be calculated as:

σM = σ / √n = 1200 / √400 = 60

To find the probability that the sample mean is within $80 of the population mean, we need to find the z-scores for the upper and lower limits of the interval:

Lower limit: z = (mean - E - population mean) / σM = (-80) / 60 = -1.3333

Upper limit: z = (mean + E - population mean) / σM = 80 / 60 = 1.3333

Using a standard normal distribution table or calculator, we can find the area under the curve between these two z-scores:

P(-1.3333 < Z < 1.3333) = 0.8461

Therefore, the probability that the mean tariff rate of 400 randomly selected railroad-car shipments of ethanol will be within $80 of the mean tariff rate of all railroad-car shipments of ethanol is approximately 0.846 or 84.6%.

Interpretation: This means that if we take many samples of 400 railroad-car shipments of ethanol and calculate their mean tariff rates, about 84.6% of these means will be within $80 of the true mean tariff rate of all ethanol shipments. This also means that there is a sampling error of $80, which is the maximum amount by which the sample mean may differ from the population mean due to random sampling variability.

Length is a measurement of the extent of something along its longest dimension, from one end to the other. It is often expressed in units such as meters, feet, or inches.

According to the given information:

To calculate the length of HG, we can use the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of its two legs.

First, we can identify that triangle HGN is a right triangle, with HG being the hypotenuse. Using the Pythagorean theorem, we have:

(HG)² = (NG)² + (NH)²

We can also identify that triangle INH is also a right triangle, with IN being the hypotenuse. Using the Pythagorean theorem, we have:

(IN)² = (NH)² + (NI)²

Substituting (NH)^2 from the second equation into the first equation, we get:

Answer:

g) The correct option is: p/q ≤ 6

The phrase "the quotient of p and q" means p divided by q, which is expressed as p/q. The statement "the quotient of p and q is at most 6" means that the value of p/q cannot exceed 6, but it can be less than or equal to 6. Therefore, we use the less than or equal to a symbol (≤) to represent this statement.

here is an explanation of each option:

Here's how to express each statement as an inequality in terms of 8a^2:

p/q ≤ 6:

p ≤ 6q

Step-by-step explanation:

This question might be a bit confusing since a lot of questions like this one require actually visualizing the question. The man in the lighthouse isn't trying to throw the rope directly in front of him to the birds, but rather to the boat.

The angle of depression here is the angle formed from the rope and the man's line of sight. Therefore, the angle of depression is congruent to the angle's alternate interior counterpart, which is the angle of elevation formed from the boat to the water.

From there, we solve like an angle of elevation question. We have the rope length, which is the hypothenuse, but we need to find the length of the side adjacent to the angle of elevation. So, we use cosine.

We just need to plug in the values here. The measure of the angle goes right next to the trig function we are using, and in cosine, the measure of the adjacent angle goes over the measure of the hypothenuse.

Therefore, the answer is D, or the last option.

Answer:

[tex]\textsf{D)} \quad \cos \left(24^{\circ}\right)=\dfrac{x}{45}[/tex]

Step-by-step explanation:

The angle of depression is the angle between the horizontal line of sight of the man in the lighthouse, and the direct line of sight to the boat below him.

To find how far from land the boat is, we can model the scenario as a right triangle.

The angle of depression (24°) is the angle formed by the hypotenuse and the horizontal leg of the right triangle.

If the distance to throw a rope from the top of the lighthouse to the boat is 45 feet, then the hypotenuse of the triangle is 45 feet.

The distance between the boat and the land is the side adjacent to the angle, so we can find this by using the cosine trigonometric ratio.
