The appropriate "Null-Hypothesis" would be (a) population proportion is equal to 0.60.

In hypothesis testing, the null-hypothesis (H₀) represents the default assumption or claim that is being tested. It is generally stated as an equality or a specific value that is being tested against an alternative hypothesis (H₁).

In this case, the null-hypothesis is stating that the population proportion is equal to a specific value of 0.60. The alternative hypothesis, which is not provided in the options, would state a different relationship or inequality, such as the population proportion being greater than or less than 0.60.

The other options (b) the population proportion is not equal to 0.60 and (c) the sample-proportion is equal to 0.60, are not appropriate null hypotheses because they do not directly test population proportion.

B. 2 and OD. 15 are not possible lengths for the third side of the triangle.

To determine the possible values for the length of the third side of a triangle, we need to consider the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Given that two sides have lengths 6 and 9, we can analyze the possibilities:

6 + 9 > x

x > 15 - The sum of the two known sides is greater than any possible third side.

6 + x > 9

x > 3 - The length of the unknown side must be greater than the difference between the two known sides.

9 + x > 6

x > -3 - Since the length of a side cannot be negative, this inequality is always satisfied.

Based on the analysis, the possible values for the length of the third side are:

The two types of control charts for variables are the X-bar chart and the R-chart.

Control charts are widely used in statistical process control to monitor and analyze the variability and stability of processes over time. They are used for variables data, which are measurements or observations that can be quantified.

1. X-bar Chart: The X-bar chart is used to monitor the central tendency or average of a process. It tracks the sample means over time to detect any shifts or trends. It helps in assessing whether the process is in control or if there are any systematic variations from the target value.

2. R-chart (Range chart): The R-chart is used to monitor the variability or dispersion within a process. It tracks the ranges (the difference between the highest and lowest values) of samples over time. By analyzing the range values, it helps in understanding whether the process is stable and consistent or if there are any unusual variations or outliers.

Together, the X-bar chart and the R-chart provide valuable insights into process performance and allow for early detection of any deviations or abnormalities, helping organizations maintain quality standards and take appropriate corrective actions when necessary.

The sample size of the poll was 100.

We can use the formula for the standard error of a proportion to solve for the sample size:

standard error = √[(p * (1 - p)) / n]

where p is the proportion and n is the sample size.

Substituting the given values:

0.0458 = √[(0.70 * (1 - 0.70)) / n]

Squaring both sides and simplifying, we get:

0.0021 = (0.70 * 0.30) / n

0.0021 = 0.21 / n

There are nC2 different votes possible, where n is the number of bands on the list and nC2 represents the number of ways to choose 2 bands out of n.

To calculate nC2, we can use the formula for combinations, which is given by n! / (2! * (n-2)!), where ! represents factorial.

Let's say there are m bands on the list. The number of ways to choose 2 bands out of m can be calculated as m! / (2! * (m-2)!). Simplifying this expression further, we get m * (m-1) / 2.

Therefore, the number of different votes possible is m * (m-1) / 2.

In the given scenario, we don't have the specific number of bands on the list, so we cannot provide an exact number of different votes. However, you can calculate it by substituting the appropriate value of m into the formula m * (m-1) / 2.

In Paul's design, C=60°, 2C=120°. These lines cannot be parallel because the angles of the lines must be the same.

An angle in Euclidean geometry is the figure formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle. Angles generated by two rays are in the plane in which the rays are located. The intersection of two planes also produces angles. These are called dihedral angles.

Angle can also refer to the measurement of an angle or rotation. This metric is the length of a circular arc divided by its radius. In the case of a geometric angle, the arc is defined by its sides and is centered at the vertex.

Answer:

(5, 38)

Step-by-step explanation:

To find the vertices of the quadratic function f(x) = x^2 - 10x + 13 using squared interpolation, do the following:

step 1:

Group the terms x^2 and x.

f(x) = (x^2 - 10x) + 13

Step 2:

Complete the rectangle for the grouped terms. To do this, take half the coefficients of the x term, square them, and add them to both sides of the equation.

f(x) = (x^2 - 10x + (-10/2)^2) + 13 + (-10/2)^2

= (x^2 - 10x + 25) + 13 + 25

Step 3:

Simplify the equation.

f(x) = (x - 5)^2 + 38

Step 4:

The vertex form of the quadratic function is f(x) = a(x - h)^2 + k. where (h,k) represents the vertex of the parabola. Comparing this to the simplified equation shows that the function vertex is f(x) = x^2 - 10x + 13 (h, k) = (5, 38).

So the vertex of the quadratic function is (5, 38).

The maximum profit is achieved when approximately 312.5 units of lab equipment are sold.

The revenue function R(x) represents the amount of money the company earns from selling x units of lab equipment. It is given by the equation:

R(x) = -0.32x^2 + 270x

The costs function C(x) represents the expenses incurred by the company for producing and selling x units of lab equipment. It is given by the equation:

C(x) = 70x + 52

To determine the company's profit, we subtract the costs from the revenue:

Profit = Revenue - Costs

P(x) = R(x) - C(x)

Substituting the given revenue and costs functions:

P(x) = (\(-0.32x^2 + 270x)\) - (70x + 52)

Simplifying the equation:

P(x) = -0.32x^2 + 270x - 70x - 52

P(x) = -\(0.32x^2\)+ 200x - 52

The profit function P(x) represents the amount of money the company makes from selling x units of lab equipment after deducting the costs. It is a quadratic function with a negative coefficient for the x^2 term, indicating a downward-opening parabola. The vertex of the parabola represents the maximum profit the company can achieve.

To find the maximum profit and the corresponding number of units sold, we can use the vertex formula:

x = -b / (2a)

For the profit function P(x) = -\(0.32x^2 + 200x\)- 52, a = -0.32 and b = 200.

x = -200 / (2 * -0.32)

x = 312.5

Therefore, the maximum profit is achieved when approximately 312.5 units of lab equipment are sold.
