Answer:

[tex]C = 43.96 \text{ miles}[/tex]

Step-by-step explanation:

The circumference (perimeter) of a circle is defined as:

[tex]C = \pi \cdot d[/tex],

where [tex]d[/tex] is the circle's diameter.

We can plug in 14 for the diameter and 3.14 for π, then solve for C.

[tex]C = 3.14 \cdot 14[/tex]

[tex]C = 43.96 \text{ miles}[/tex]

Note that we can also write the circumference formula as:

[tex]C = 2\pi r[/tex]

because [tex]d = 2\cdot r[/tex].

We would expect the size of the population to increase by 12 individuals.

Here are the terms we'll be using:
- Initial population size: 100 individuals
- Per capita birth rate: 0.25
- Per capita death rate: 0.13
To find the expected increase in population size, follow these steps:
Calculate the net per capita growth rate by subtracting the per capita death rate from the per capita birth rate:
Net per capita growth rate = Per capita birth rate - Per capita death rate
Net per capita growth rate = 0.25 - 0.13
Net per capita growth rate = 0.12.

Multiply the net per capita growth rate by the initial population size to find the expected increase in the number of individuals:
Expected increase = Net per capita growth rate × Initial population size
Expected increase = 0.12 × 100
Expected increase = 12 individuals.

Area of a parallogram is:

A=bh       here b=5 and h=3    b, base is the bottom line

                                                 h, is the straight line going up and dow

A=(5)(3)

=15 m²

Answer:

  see attached

Step-by-step explanation:

You want the graph of (x, y) = (2 -t, (t+3)²) on the interval t ∈ [-4, 0].

You can use the parametric equations to find several points on the graph, or you can write y in terms of x:

  x = 2 -t

  t = 2 -x . . . . . . . . . add t-x to both sides

Substituting into the expression for y, we have ...

  y = (t +3)²

  y = (2 -x +3)²

  y = (5 -x)² = (x -5)²

The graph of this is the parent parabola function y=x² shifted right by 5 units.

The domain of t is [-4, 0], so the domain of x is 2 -[-4, 0] = [6, 2]. The above-described parabola will be found between x=2 and x=6, on the interval [2, 6].

The range is from the minimum at (5, 0) to the maximum at (2, 9). The range is described by the interval [0, 9].

__

Additional comment

You know that x² ≡ (-x)², so we can write y = (5 -x)² in the form y = (x -5)² without changing any of the ordered pairs it describes. Having a positive x-coefficient tends to reduce anxiety (and errors), so the latter form is usually preferred.

The surface area of the rectangular prism is 166 in².

To arrive at the surface area, we will use the following formula which gets the area for the right, left, and bottom parts.

Surface Area = 2(wl+hl+hw)

Surface Area = 2 (6*2 + 9*2 + 9*6)

SA = 2(12 + 18 + 54)

SA =2(84)

SA = 166 in²

We can calculate the probabilities of getting a specific number of science majors in the class, as well as the expected number of science majors.

The number of students that are science majors can be thought of as a binomial random variable if the following conditions are met:

Under these conditions, we can model the number of science majors as a binomial random variable, which is the number of successes in a fixed number of independent trials, where each trial has the same probability of success.

In this case, each student is a trial, and the probability of success is the probability of being a science major. The binomial distribution describes the probability of getting a specific number of successes in a fixed number of trials, given a specific probability of success.

This makes the binomial distribution a useful tool for modeling situations where we are interested in the number of successes in a fixed number of independent trials, such as the number of students who are science majors in a class.

Tiffany should have expected the spinner to land in the orange section 10 more times.

To find out how many more times Tiffany should have expected the spinner to land in the orange section, we need to determine the expected number of times the spinner would land in the orange section based on the given information.

Tiffany spun the spinner 96 times, and it landed in the orange section 10 times. To find the expected number of times the spinner would land in the orange section, we can calculate the proportion of spins that landed in the orange section.

Proportion of spins in the orange section = (Number of orange spins) / (Total number of spins)

Proportion of spins in the orange section = 10 / 96

Now, to find the expected number of orange spins, we multiply the proportion by the total number of spins:

Expected number of orange spins = Proportion of spins in the orange section * Total number of spins

Expected number of orange spins = (10 / 96) * 96

A variable declared as `final` in Java cannot be changed after it is initialized and acts as a constant. Static variables are used to share a common value across all instances of a class.

In Java, the `final` keyword is used to declare a variable that cannot be changed after it is initialized. Such a variable is often referred to as a constant. If a variable is declared as `final`, it must be initialized at the time of declaration, and once initialized, its value cannot be changed. Therefore, if a `final` variable is declared and initialised , but never changed, it will effectively act as a constant throughout the program.

Static variables are used to share a common value across all instances of a class, and can be changed during the program's execution. Literals are used to represent fixed values in code, such as string or numeric literals. Formal parameters are variables used to pass values into a method, and their values can be changed by the method code.

Brenda should poll at least 847 students to create a 98% confidence interval with a margin of error of at most 4%.

To calculate the sample size needed for a 98% confidence interval with a margin of error of at most 4%, we'll need to use the following formula:
[tex]n = (Z^2 * p * (1-p)) / E^2[/tex]
where:
- n is the sample size
- Z is the Z-score corresponding to the desired confidence level (98% in this case)
- p is the estimated proportion of students with job offers before graduation (we'll use 0.5 for a conservative estimate)
- E is the margin of error (4% or 0.04)
Here's a step-by-step process to calculate the sample size using Excel:
Find the Z-score for a 98% confidence interval:

Using the NORM.S.INV function in Excel, enter "=NORM.S.INV(0.99)" to get the Z-score for a 98% confidence interval. The result is approximately 2.33.

Use the formula with the given values:

In a new cell, enter the formula with the calculated Z-score,

p=0.5,

and E=0.04:
 [tex]=(2.33^2 * 0.5 * (1-0.5)) / 0.04^2[/tex]

Press Enter to calculate the sample size:

After entering the formula, press Enter to get the sample size.

The result is approximately 846.25.
Round up the sample size:

Since you cannot poll a fraction of a student, round up the sample size to the nearest whole number. In this case, round up 846.25 to 847.

The probability that the sample mean will be larger than 49 can be calculated using the standard normal distribution.



Since we know the population mean and standard deviation, we can use the central limit theorem to assume that the distribution of sample means is normal with a mean of 52 and a standard deviation of 20/√50) = 2.83.

To find the probability that the sample mean will be larger than 49, we can standardize the distribution using the z-score formula:

z = (sample mean - population mean) / (standard deviation / √(sample size))

z = (49 - 52) / (20/√(50)) = -1.77

Using a standard normal distribution table or calculator, we can find that the probability of z being less than -1.77 is approximately 0.0384.

Therefore, the probability that the sample mean will be larger than 49 is:

1 - 0.0384 = 0.9616

or 96.16%.

Calculation:

z = (49 - 52) / (20/√50)) = -1.77

Probability of z being less than -1.77 = 0.0384

Probability of sample mean being larger than 49 = 1 - 0.0384 = 0.9616 or 96.16%.

Non-parametric methods assume the sample used is the population and do not make assumptions about the underlying distribution of the population. Results obtained from non-parametric methods are specific to the sample used and cannot be generalized to the larger population.

The methods that assume the sample used is the population, and so results cannot be extrapolated beyond that particular sample, are known as non-parametric methods. Non-parametric methods do not make any assumptions about the underlying distribution of the population, and instead rely solely on the observed data. As a result, the results obtained from non-parametric methods are specific to the sample used and cannot be generalized to the larger population.

Theorem 4.4.2 states that the only divisors of the integer 1 are 1 and -1. In other words, no other integer except 1 and -1 can divide 1.

To prove this theorem, we can use the definition of divisibility, which states that if a and b are integers, then a divides b if and only if there exists an integer k such that b = ak. Since 1 is the smallest positive integer, it has only two divisors, namely 1 and -1.

If a is a positive integer that divides 1, then a must be equal to 1, since it is the only positive integer that is smaller than or equal to 1. If a is a negative integer that divides 1, then a must be equal to -1, since it is the only negative integer that is greater than or equal to -1.

Thus, we have shown that the only divisors of 1 are 1 and -1, which proves Theorem 4.4.2. This theorem is a simple but important result in number theory, as it establishes a fundamental property of the number 1 and its divisors.
