Answer:

Step-by-step explanation:

Consider a utlity bill which shows a minimum initial cost plus variable costs dependent upon how many units are sold.

Then:  total cost ≥ (fixed cost) + (unit cost)(number of units sold)  

This involves the "equal to or greater than" concept.

There are at least two group means that are significantly different from one another, according to the alternative hypothesis (H a). The alternative hypothesis is adopted if the outcome is statistically significant.

You can use ANOVA to determine whether differences between data sets are statistically significant. It functions by examining the levels of variance present within each group using samples drawn from each.

The likelihood that the mean of a sample taken from the data will be different owing to chance increases if there is a lot of variance (spread of data away from the mean) among the data groups.

In addition to examining the variance within the data groups, ANOVA also considers sample size (the smaller the sample, the lower the likelihood that outliers will be randomly selected from it) and sample mean differences (the greater the difference between the sample means, the greater the likelihood that an outlier will be randomly selected from it).

hence, The alternative hypothesis is adopted if the outcome is statistically significant.

Answer:

Correct Answer: A.

Step-by-step explanation:

A) The height of the water increases 2 inches per minute.

Step-by-step explanation:

Slope is the rate of change of height

m = (16 - 12)/(4 - 2) = 4/2 = 2

2 inch per min

Positive slope implies increase

The formula we need to use is given above. In this formula, we will substitute the desired values. Let's start.

A) First, we can start by analyzing the first premise. The team has \(8\) wins and \(5\) losses. It earned \(8 \times 3 = 24\) points in total from the matches it won and \(1\times5=5\) points in total from the matches it drew. Therefore, it earned \(24+5=29\) points.

B) After \(39\) matches, the team managed to earn \(54\) points in total. \(12\) of these matches have ended in draws. Therefore, this team has won and lost a total of \(39-12=27\) matches. This number includes all matches won and lost. In total, the team earned \(12\times1=12\) points from the \(12\) matches that ended in a draw.

\(54-12=42\) points is the points earned after \(27\) matches. By dividing \(42\) by \(3\) ( because \(3\) points is the score obtained as a result of the matches won), we find how many matches team won. \(42\div3=14\) matches won.

That leaves \(27-14=13\) matches. These represent the matches team lost.

Finally, the answers are below.

\(A)29\)
\(B)13\)

Answer:

  a) 29 points

  b) 13 losses

Step-by-step explanation:

You want to know points and losses for different teams using the formula P = 3W +D, where W is wins and D is draws.

The number of points the team has is ...

  P = 3W +D

  P = 3(8) +(5) = 29

The team has 29 points.

You want the number of losses the team has if it has 54 points and 12 draws after 39 games.

The number of wins is given by ...

  P = 3W +D

  54 = 3W +12

  42 = 3W

  14 = W

Then the number of losses is ...

  W +D +L = 39

  14 +12 +L = 39 . . . substitute the known values

  L = 13 . . . . . . . . . . subtract 26 from both sides

The team lost 13 games.

__

Additional comment

In part B, we can solve for the number of losses directly, using 39-12-x as the number of wins when there are x losses. Simplifying 3W +D -P = 0 can make it easy to solve for x. (In the attached, we let the calculator do the simplification.)

Ninety percent of all students at private universities pay less than approximately $25,692.

To find the amount that ninety percent of all students at private universities pay less than, we need to use the cumulative distribution function of the standard normal distribution.

First, we need to find the z-value corresponding to the cumulative probability of 0.90. Using a standard normal distribution table or calculator, the z-value for a cumulative probability of 0.90 is approximately 1.28 (rounded to 2 decimal places).

Next, we can use the formula for the normal distribution to find the amount. The formula is:
Amount = Mean + (z * Standard Deviation)

Plugging in the given values, we have:
Amount = $20,132 + (1.28 * $4,450)

Calculating this, we get:
Amount ≈ $25,692

Therefore, ninety percent of all students at private universities pay less than approximately $25,692.

The mercury manometer reading is approximately 4.908 meters and

Pressure difference = 684240.14 N/m².

To calculate the mercury manometer reading, we can use the Bernoulli's equation, which relates the pressure, velocity, and elevation of a fluid in a flowing system.

Given:

Pipeline diameter (D₁) = 300 mm

= 0.3 m

Throat diameter (D₂) = 100 mm

= 0.1 m

Velocity at the throat (V₂) = 10 m/s

Coefficient of discharge (Cp) = 0.97

Specific gravity of mercury (SG) = 13.6

Step 1: Calculate the velocity at the pipeline entrance (V₁) using the continuity equation, which states that the mass flow rate is constant:

A₁V₁ = A₂V₂

A₁ = (π/4)D₁² (cross-sectional area at pipeline entrance)

A₂ = (π/4)D₂² (cross-sectional area at throat)

V₁ = (A₂/A₁) × V₂

V₁ = [(0.1)²/(0.3)²] × 10

V₁ = 1.11 m/s

Step 2: Calculate the pressure difference (ΔP) using Bernoulli's equation:

ΔP = (1/2)ρ(V₂² - V₁²) / Cp

where ρ is the density of water

ρ = SG × ρ_water

= 13.6 × 1000 kg/m³

(assuming \(\rho_{water}\) = 1000 kg/m³)

ΔP = (1/2)(13.6 * 1000)(10² - 1.11²) / 0.97

= 684240.14 N/m²

Step 3: Convert pressure to mercury manometer reading:

Since the specific gravity (SG) of mercury is 13.6, the height of the mercury column (h) in the manometer can be calculated using the equation:

\(\Delta P=\rho_{mercury}\times g\times h\)

\($h=\frac{\Delta P}{(\rho_{mercury\times g})}\)

where g is the acceleration due to gravity (9.81 m/s²) and \(\rho_{mercury\) is the density of mercury.

\(\rho_{mercury\) = SG ×  \(\rho_{water}\)

= 13.6 * 1000 kg/m³

h = (684240.14) / (13.6 × 1000 * 9.81)

= 4.908 m

Therefore, the mercury manometer reading is approximately 4.908 meters.

Conclusion: Mercury manometer reading = 4.908 m

Pressure difference = 684240.14 N/m²

The statement "Length of 'center' must equal the number of columns of 'x'" is generally false. The length of the 'center' variable does not necessarily need to equal the number of columns of 'x'.

The requirement for the length of 'center' depends on the specific context or purpose of its usage in relation to 'x'. In some cases, 'center' may represent a vector or an array containing the central values or positions of a dataset or matrix. In such cases, the length of 'center' would typically match the dimensionality of the dataset or matrix, which would correspond to the number of rows or columns in 'x'. However, there can be situations where 'center' represents something else entirely, such as a single value or a different set of values unrelated to the dimensions of 'x'. Therefore, it is not a general rule that the length of 'center' must always equal the number of columns of 'x'. The specific requirements and relationships between 'center' and 'x' would depend on the specific context and purpose of their usage.

The probability of it raining 5 days out of the week, given an average chance of rain of 36% each day, is approximately 0.036 or 3.6%.

To find the probability of it raining 5 days out of the week when the chance of rain each day is 36%, we can use the binomial probability formula.

The binomial probability formula is given by:

P(X = k) = (nCk) * p^k * (1-p)^(n-k)

Where:

P(X = k) is the probability of getting exactly k successes

n is the number of trials

k is the number of desired successes

p is the probability of success in a single trial

(1-p) is the probability of failure in a single trial

In this case, we have:

n = 5 (number of days in the week)

k = 5 (desired number of rainy days)

p = 0.36 (probability of rain each day)

Using the formula, we can calculate the probability:

P(X = 5) = (5C5) * (0.36)^5 * (1-0.36)^(5-5)

Simplifying the equation:

P(X = 5) = 1 * 0.36^5 * 0.64^0

P(X = 5) ≈ 0.036

The statement that is true is, a hypothesis can be differentiated from a theory because it is a specific prediction arising from the theory. A hypothesis is a suggested explanation of a phenomenon or observed data that is testable.

Hypotheses are more detailed, and are written to explain precisely what you think is going to occur in your research and the reason for that prediction. A hypothesis will be rejected if it does not fit the data, whereas a theory will be modified to fit the data.

A hypothesis is more like a forecast, and a theory is more like a law that explains how certain events operate. Thus, we can conclude that a hypothesis is a specific prediction arising from the theory.
