The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.

The probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated can be calculated using the binomial probability formula.

The binomial probability formula is used to calculate the probability of a given number of successes from a given number of trials when the probability of success is constant. In this case, the number of trials is 3 (i.e. the three randomly selected people) and the probability of success is 64% (i.e. the probability that each of the randomly selected people has been vaccinated).

To calculate the probability that at least one of the three randomly selected people has been vaccinated, we first calculate the probability of none of them having been vaccinated:
P(none) = (1 - 0.64)^3 = 0.216

Then, the probability of at least one of them having been vaccinated is 1 - P(none) = 1 - 0.216 = 0.784.

In conclusion, the probability that at least one of three randomly selected people has been vaccinated in a large population where 64% of people have been vaccinated is 0.784.

If a distribution of scores is shown in a bar graph, it suggests that the scores were measured on an ordinal scale of measurement.

An ordinal scale is a type of measurement scale that categorizes and orders variables or data points based on their relative ranking or position. In this case, the bar graph represents the frequencies or counts of different categories or ranges of scores, indicating an ordered arrangement of the data. However, the bar graph alone does not provide information about the exact numerical differences between the scores or their precise magnitudes.

Therefore, the length of a side of the square is x/4 inches by the equation.

In this context, we have a wire that we need to bend into a square. A square has four equal sides, so if we let s be the length of one side of the square, then the total length of the wire must be 4s.

The equation 4s = x represents this relationship, where x is the total length of the wire.

To solve for s, we can isolate s on one side of the equation by dividing both sides by 4. This gives us:

4s / 4 = x / 4

Simplifying, we get:

s = x / 4

a) we can conclude that a¹ cannot be written in the specified form with rational numbers e, f, g, h.  b) The quotient polynomial q(x) will be a quadratic, and r(x) will be a linear polynomial. Since a is a root of p(x), r(x) must be equal to zero.

a) To determine if a¹ can be written in the form a¹ = e + f√5 + g√7 + h√35 for rational numbers e, f, g, h, we need to simplify the expression for a. Let's start by rationalizing the denominator of the term √√35:

√√35 = √(2√5)

Let's denote √5 as x for simplicity:

√(2√5) = √2x

Now we can substitute this back into the expression for a:

a = 1 + √5 + √7 - √√35

 = 1 + √5 + √7 - √2x

As we can see, the expression contains irrational terms (√5, √7, √2x). If a could be expressed in the form a = e + f√5 + g√7 + h√35, then the irrational terms would be eliminated, but this is not the case here. Therefore, we can conclude that a¹ cannot be written in the specified form with rational numbers e, f, g, h.

b) Given that a is a root of the polynomial p(x) = x³ + p₁2¹ + P3x³ + p2r² + p1x + po, we can find three further roots by using polynomial division. We divide p(x) by (x - a) to obtain the quotient polynomial:

p(x) = (x - a) * q(x) + r(x)

The quotient polynomial q(x) will be a quadratic, and r(x) will be a linear polynomial. Since a is a root of p(x), r(x) must be equal to zero. Solving for q(x) will give us the quadratic polynomial, and finding its roots will provide the three further roots.

c) Given the constraints, it appears that there may be an error in the formulation of the question. The provided polynomial p(x) does not seem to be accurately defined, as it contains terms like p₁2¹ and p2r². Without the correct definitions for these terms, it is not possible to find specific values for Po, P1, P2, P3, P4.

The missing part of the equation is \(-7.0\times10^4 s^2kg⋅m^2 / 1000000.\)

To fill in the missing part of the equation, let's analyze the given information and the desired conversion. The equation is:

\((-7.0\times 10^4 s^2g⋅m^2)\cdot \pi = ? s^2kg\cdot m^2\)

In this equation, we have a quantity expressed in\(s^2g\cdot m^2\) units on the left-hand side. To convert it to \(s^2kg\cdot m^2\) units, we need to multiply it by a conversion factor.

To perform the conversion, we can use the fact that 1 kg is equal to 1000 g. Therefore, the conversion factor we need is:

1 kg / 1000 g

To ensure that the units cancel out correctly, we need to square this conversion factor because we have \(s^2g\cdot m^2\) on the left-hand side. So the missing part of the equation is:

\((-7.0\times 10^4 s^2g\cdot m^2)\cdot \pi = (-7.0\times 10^4 s^2g\cdot m^2)\cdot (1 kg / 1000 g)^2\)

Simplifying this expression, we get:

\((-7.0\times10^4 s^2g\cdot m^2)\cdot \pi = -7.0 \times10^4 s^2kg\cdot m^2 / 1000000\)

Therefore, the missing part of the equation is \(-7.0 \times 10^4 s^2kg\cdot m^2 / 1000000.\)

The best measure of center for the given data set of eye colors from 250 randomly selected statistics students would likely be the mode, representing the most frequently occurring eye color.

To determine which measure of center would be best for the given data set, which consists of a list of eye colors from 250 randomly selected statistics students, we can consider the following options:

Mode: The mode represents the most frequently occurring eye color in the data set. If there is a clear eye color that occurs more frequently than others, the mode can be a suitable measure of center. For example, if the majority of students have brown eyes, and brown is the most common eye color in the data set, then the mode would be a relevant measure of center.

Nonzero axis: It is unclear what is meant by "nonzero axis" in this context. Please provide additional clarification if this term refers to a specific statistical measure.

Relative frequency: Relative frequency refers to the proportion or percentage of observations that fall into each category. In this case, it would involve calculating the relative frequency of each eye color category based on the 250 students. This measure of center can provide a sense of the distribution of eye colors among the students and identify any dominant categories.

Graphs: Graphical representations, such as bar charts or pie charts, can visually display the distribution of eye colors among the 250 students. These graphs can help identify any prominent eye color categories and provide a visual summary of the data.

Ultimately, the best measure of center for the data set would depend on the distribution of eye colors and whether there is a clear dominant category. It is advisable to explore all the mentioned options (mode, relative frequency, and graphs) to gain a comprehensive understanding of the data and determine the most appropriate measure of center.

Answer is the fee at bank L will be the same as P when the checking fee is 600.

(a) Since the sample size is large (n=105) and the population standard deviation is known, we can use a z-test.

The test statistic is calculated as:

z = (x - μ) / (σ / sqrt(n))

where x is the sample mean, μ is the hypothesized population mean, σ is the population standard deviation, and n is the sample size.

Plugging in the values given in the problem, we get:

z = (16 - 15.8) / (1.1 / sqrt(105)) ≈ 1.35

So the test statistic is z = 1.35.

(b) Since the sample size is small (n=20) and the population standard deviation is unknown, we can use a t-test.

The test statistic is calculated as:

t = (x - μ) / (s / sqrt(n))

where x is the sample mean, μ is the hypothesized population mean, s is the sample standard deviation, and n is the sample size.

Plugging in the values given in the problem, we get:

t = (16 - 15.8) / (1.4 / sqrt(20)) ≈ 0.76

By applying the exterior angle of a triangle theorem, m<WUV = 19°

What is an exterior angle of a triangle?

The angle created by one side of a triangle and the subsequently extended side is known as the external angle of a triangle. A triangle has three exterior angles, and the sum of those three external angles is always 360 degrees.

Here, we have

The given parameters are;

ΔUVW with side UW extended to X

m∠UVW = (x + 19)°

m∠VWX = (5x +14)°

m∠WUV = (x + 13)°

Applying the exterior angle of a triangle theorem:

m∠WUV + m∠UVW = m∠VWX

(x + 13)° + (x + 19)° = (5x +14)°

2x + 32 = 5x + 14

32 - 14 = 5x - 2x

18 = 3x

x = 6°

Now, we put the value of x in m∠WUV = (x + 13)° and we get

m∠WUV = (6+13)°

m∠WUV = 19°

Hence, by applying the exterior angle of a triangle theorem, m<WUV = 19°

The ball reaches maximum height in 3 seconds.

The maximum height of the ball is of 400 feet.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

\(f(x) = ax^{2} + bx + c\)

It's vertex is the point \((x_{v}, f(x_{v})\)

In which

\(x_{v} = -\frac{b}{2a}\)

If a<0, the vertex is a maximum point, that is, the maximum value happens at \(x_{v}\), and it's value is \(f(x_{v})\)

In this question:

The height is modeled by:

\(s(t) = -16t^2 + 96t + 256\)

So, the coefficients are:

\(a = -16, b = 96, c = 256\)

Instant of time the ball reaches maximum height:

\(t_{v} = -\frac{96}{2(-16)} = -\frac{96}{-32} = 3\)

The ball reaches maximum height in 3 seconds.

What is the maximum height of the ball?

This is s(3).

\(s(3) = -16t^2 + 96t + 256 = -16*3^2 + 96*3 + 256 = 400\)
