Answer:

A) doubling time growth model

Step-by-step explanation:

Doubling time growth model can be defined as the total or overall number of time it takes for a specific quantity to increase by doubling in value or size at a constant growth rate.

Mathematically, the doubling time growth model is given by the rule of 70;

\(dt = \frac{70}{r}\)

Where,

dt represents the doubling time.

r is the growth rate.

Hence, a doubling time growth model would best describe the population of a city if it increases in size by a factor of two every 29 years. The doubling time growth model is typically used to study or model the human population growth.

6.56 × 1.2= 7.872 = 7.9 [ to 2 significant figures]

Significant figure

Significant figures are the number of digits in value, often measurement, that contribute to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit. Calculate the number of significant figures for an assortment of numbers.

fewest; the same significant figures with; measured numbers

Without mincing words let us dive straight into the solution to the above question. In order to be able to use the significant figures properly one must know the rules attached to it uses. This is so, because they contributes to the precision of measurements.

When performing multiplication or division calculation, the number of significant figures in the answer[result] will be determined by the one with the smallest number of significant figure in the problem.

Therefore, if we have 6.56 which is three[3] significant figures and 1.2 which is two[2] significant figures, then the number of significant figures will be two[2].

6.56 × 1.2= 7.872 = 7.9[ to 2 significant figures].

4th degree polynomial with 4 terms

Step-by-step explanation:

Given:

3n²(n²+ 4n - 5) - (2n² - n⁴ + 3)

Open parenthesis

= 3n⁴ + 12n³ - 15n² - 2n² + n⁴ - 3

Collect like terms

Number 1 term is 4n²

Number 2 term is 12n³

Number 3 term is -17n³

Number 4 term is -3

The highest degree of the polynomial is 4th degree

By following these steps, we can easily find the slope of a normal line based on the equation of a tangent line.

To find the slope of a normal line based on the equation of a tangent line.

Identify the slope of the tangent line:

Look at the equation of the tangent line, which will usually be in the form y = mx + b, where m is the slope of the tangent line and b is the y-intercept.

Extract the value of m from the equation.
Calculate the negative reciprocal:

To find the slope of the normal line, we'll need to calculate the negative reciprocal of the tangent line's slope.

The negative reciprocal of a number is found by flipping the fraction and changing the sign (from positive to negative, or from negative to positive).

For example, if the slope of the tangent line (m) is 3, the negative reciprocal will be -1/3.

If the slope of the tangent line is -2/3, the negative reciprocal will be 3/2.
The slope of the normal line:

The negative reciprocal calculated in step 2 is the slope of the normal line.

This slope will be perpendicular to the tangent line, meaning that the angle between the normal and tangent lines is 90 degrees.

Step-by-step explanation:

The median number of siblings for all the 300 students selected randomly from two schools and surveyed is equals to the 1. So, the correct choice for this problem is option (b).

The median of a data set is the middle value when the data points are sorted in either ascending or descending order. In case of odd number of data values, the middle value is median but in case of even number of values the arithmetic mean two middle value is median. We have a total of 600 data points provided, which is even so the median will be the average of the 300ᵗʰ and 301ᵗʰ data points. When the data points are sorted in order

Therefore, both the 300ᵗʰ and 301ˢᵗ values are 1, and hence the median is 1.

So, here choices A, C, and D are incorrect . Hence, required value is 1.

The subshell designated by each set of quantum numbers is as follows:

a) n=3, l=1 -> 3p subshell

b) n=4, l=2 -> 4d subshell

c) n=2, l=0 -> 2s subshell

d) n=5, l=3 -> 5f subshell

In the electron configuration of an atom, each electron is described by a set of four quantum numbers, which includes the principal quantum number (n), the angular momentum quantum number (l), the magnetic quantum number (m), and the spin quantum number (s). The second quantum number (l) determines the shape of the subshell, which in turn influences the energy level and chemical behavior of the atom. The letter designation for each subshell is based on the value of the angular momentum quantum number (l): s (l=0), p (l=1), d (l=2), f (l=3), and so on. Therefore, for a given set of quantum numbers, we can determine the subshell designation by identifying the value of l.

The most reasonable formula to find the interval is

0.35 ± 2.576 (√ (0.35 × 0.65)/100).

The subset chosen from the larger set to make assumptions is known as a random sample. A range of values is a confidence interval.  

According to the given problem, n =100 and x = 35

To estimate the true population of students who travelled outside the US using a 99% confidence interval:

p   =   x / n

    =   35 / 100

p   =   0.35

At 99% confidence,

α   =   1 - 0.99

α   =   0.01

α/2   =   0.01/2

α/2   =   0.005

∴  z(α/2)   =   \(z_{0.005}\)   =   2.576

99% confidence interval (CI) is,

CI    =   p ± z(α/2) * √(p(1-p)/n)

      =   0.35 ± 2.576 * \(\sqrt{\frac{0.35(1-0.35)}{100} }\)

      =   0.35 ± 2.576 * \(\sqrt{\frac{0.35(0.65)}{100} }\)

      =   0.35 ± 2.576 * \(\sqrt{\frac{0.2275}{100} }\)

      =   0.35 ± 2.576 * \(\sqrt{0.002275}\)

      =   0.35 ± 2.576 * 0.0476969600

      =   0.35 ± 0.122867391

      =   ( 0.35 - 0.1229,0.35 + 0.1229 )

CI    =   ( 0.2271,0.4729 )

Therefore, the most reasonable formula to find the interval is,

0.35 ± 2.576 × \(\sqrt{\frac{0.35 * 0.65}{100} }\)

The blank space is 0.27 approximately

Step-by-step explanation:

Here is a multiplication problem in which we are to fill in the blank.

Let’s represent the blank by x

So we have ;

3.7 * x * 3.7 = 3.719

13.69 * x = 3.719

x = 3.719/13.69

x = 0.27 approximately

The hiker used approximately 56.88 Watts of power in climbing the hill.

Power is defined as the rate at which work is done or energy is transferred. To calculate the power used by the hiker in climbing the hill, we need to know the amount of work done and the time it took.

The work done can be calculated as the product of the force applied and the distance moved. In this case, the force applied is equal to the weight of the hiker, which can be calculated as the mass multiplied by the acceleration due to gravity (9.8 m/s²).

Weight of the hiker = mass * acceleration due to gravity

Weight of the hiker = 51.7 kg * 9.8 m/s² = 506.66 N

The work done is equal to the force applied multiplied by the distance moved. In this case, the distance moved is 43.2 meters.

Work done = force * distance

Work done = 506.66 N * 43.2 m = 21,868.35 J (Joules)

Next, we need to determine the time it took to climb the hill, which is given as 384 seconds.

Now, we can calculate the power using the formula:

Power = Work done / Time

Power = 21,868.35 J / 384 s

Power ≈ 56.88 Watts

Therefore, the hiker used approximately 56.88 Watts of power in climbing the hill.
