The area of circle calculated form the circumference of circle is 6.25π cm².

The circumference of circle is represented by the formula -

Circumference = 2πr, where r is the radius of the circle.

Keep the value of circumference to find the radius of circle.

5π = 2πr

Cancelling π on each side of the equation

2r = 5

r = 5/2 cm

Now, we know the area of circle is given by the formula -

Area = πr²

Keep the values of radius in the formula -

Area = π× (5/2)²

Taking square on Right Hand Side of the equation

Area = 25π/4

Performing division on Right Hand Side of the equation

Area = 6.25π cm²

Thus, the area is 6.25π cm².

Option D

The following equation could be used to represent a function w:

= w(x)=v(x-7)+7

According to the information provided,

The point of discontinuity of rational functions is at x=7.

When a rational function has a point of discontinuity, it generally occurs when,

q(x) = r(x-a), where x = a

In this case, we must pay attention to the following relationship, which is a combination of a parent rational function and a vertical translation:, (2)

If we know that a=7 and k=7.

The equation which can represent w is as follows,

w(x) = v ( x-7 ) + 7

A rational function can be represented as a polynomial split by another polynomial. Because polynomials are defined everywhere, the domain of a rational function is the set of all numbers except the zeros in the denominator.

Example: x = f(x) (x - 3). The denominator, x = 3, has only one zero. Rational functions are no longer defined when the denominator is zero.

To find the value of x, we calculate the average of the sample observations. Summing up the observations and dividing by the total number of observations, we get:

x = (125 + 122 + 126 + 100 + 155 + 132 + 121 + 118 + 114 + 125 + 142 + 2 + 130 + 110 + 140 + 129 + 3) / 17 = 114.118 seconds (rounded to three decimal places).b) To find the value of R, we calculate the range of each sample by subtracting the minimum observation from the maximum observation. Then we find the average range across all samples:R = (155 - 100 + 142 - 2 + 140 - 110 + 132 - 114 + 142 - 3) / 5 = 109.2 seconds (rounded to three decimal places).

c) The Upper Control Limit (UCL) and Lower Control Limit (LCL) using 3-sigma can be calculated by adding and subtracting three times the standard deviation from the average:UCL = x + (3 * R / d2) = 114.118 + (3 * 109.2 / 1.693) = 348.351 seconds (rounded to three decimal places).LCL = x - (3 * R / d2) = 114.118 - (3 * 109.2 / 1.693) = -120.115 seconds (rounded to three decimal places).

d) The Upper Control Limit Range (UCLR) and Lower Control Limit Range (LCLR) using 3-sigma can be calculated by multiplying the average range by the appropriate factor:UCLR = R * D4 = 109.2 * 2.115 = 231.108 seconds (rounded to three decimal places).LCLR = R * D3 = 109.2 * 0 = 0 seconds.

The quotient of (2x4 – 3x3 – 3x2 7x – 3) ÷ (x2 – 2x 1) is 2x² + x – 3.

A quotient is a quantity produced by the division of two numbers.

The quotient is most frequently encountered as two numbers, or two variables, divided by a horizontal line. The words "dividend" and "divisor" refer to each individual part, while the word "quotient" refers to the whole.

For example when 8 is divided by 2, the result obtained is 3. Thus, the quotient is 4.

To determine the quotient when (2x4 – 3x3 – 3x2 + 7x - 3) is divided by (x2 - 2x + 1), we'll apply the long division method as shown below:

              2x² + x – 3

x² - 2x + 1|2x⁴ – 3x² – 3x² + 7x - 3

              –(2x⁴ – 2x³ + 2x²)

To determine whether there is enough evidence to reject the null hypothesis, we need to compare the computed test statistic to the critical value.

In this case, the computed test statistic is 2.50 and the critical value is 2.33. If the computed test statistic falls in the rejection region beyond the critical value, we can reject the null hypothesis. Conversely, if the computed test statistic falls within the non-rejection region, we fail to reject the null hypothesis.In this scenario, since the computed test statistic (2.50) is greater than the critical value (2.33), it falls in the rejection region. This means that the observed data is unlikely to occur if the null hypothesis were true.

Therefore, based on the given information, there is enough evidence for the emergency room nurse to reject the null hypothesis. This suggests that there is sufficient evidence to support the claim that the average number of cases of upper respiratory infections per day at the hospital is over 21 cases.

There is enough evidence to reject the null hypothesis in this case because the computed test statistic (2.50) is higher than the critical value (2.33). This suggests the average number of daily respiratory infections exceeds 21, providing substantial evidence against the null hypothesis.

Yes, there is enough evidence for the emergency room nurse to reject the null hypothesis. The null hypothesis is typically a claim of no difference or no effect. In this case, the null hypothesis would be an average of 21 upper respiratory infections per day. The test statistic computed (2.50) exceeds the critical value (2.33). This suggests that the average daily cases indeed exceed 21, hence providing enough evidence to reject the null hypothesis.

It's crucial to understand that when the test statistic is larger than the critical value, we reject the null hypothesis because the observed sample is inconsistent with the null hypothesis. The statistical test indicated a significant difference, upheld by the test statistic value of 2.50. The significance level (alpha) of 0.05 is a commonly used threshold for significance in scientific studies. In this context, the finding suggests that the increase in respiratory infection cases is statistically significant, and the null hypothesis can be rejected.

A rational function is a function that can be expressed as the quotient of two polynomials, where the denominator polynomial is not zero. In general, a rational function takes the form:

f(x) = P(x) / Q(x)

Here, P(x) and Q(x) are polynomials, and Q(x) ≠ 0. The numerator polynomial P(x) and the denominator polynomial Q(x) can have various degrees and coefficients.

Rational functions often have certain characteristics, such as vertical asymptotes, horizontal asymptotes, x-intercepts, and y-intercepts. These characteristics can be identified by analyzing the behavior of the function for different values of x.

Let's look at a couple of examples:

Example 1:

Consider the rational function f(x) = (3x^2 - 2x - 8) / (x - 2).

Here, the numerator polynomial is 3x^2 - 2x - 8, and the denominator polynomial is x - 2.

To find the vertical asymptote(s), we need to determine the value(s) of x for which the denominator Q(x) equals zero. In this case, we have x - 2 = 0, which gives x = 2. Therefore, the vertical asymptote is x = 2.

To find the x-intercept(s), we need to solve the equation P(x) = 0. In this case, we solve 3x^2 - 2x - 8 = 0. The solutions are x = -1 and x = 8/3. So, the x-intercepts are x = -1 and x = 8/3.

Example 2:

Consider the rational function g(x) = (2x + 1) / (x^2 + x - 6).

Here, the numerator polynomial is 2x + 1, and the denominator polynomial is x^2 + x - 6.

To find the vertical asymptote(s), we determine the values of x for which the denominator Q(x) equals zero. In this case, we need to solve x^2 + x - 6 = 0. Factoring the quadratic equation gives us (x - 2)(x + 3) = 0. So, the solutions are x = 2 and x = -3. Therefore, the vertical asymptotes are x = 2 and x = -3.

To find the x-intercept(s), we solve the equation P(x) = 0. In this case, we solve 2x + 1 = 0, which gives x = -1/2. So, the x-intercept is x = -1/2.

These are just a few examples illustrating the basic concepts of rational functions. Depending on the specific characteristics of the numerator and denominator polynomials, rational functions can exhibit a variety of behaviors. Analyzing their properties helps us understand their graphs and behavior in different regions of the coordinate plane.
