Ordinal and ratio scales are two different measurement scales used in statistics. The ordinal scale represents data with a rank order, while the ratio scale includes a true zero point.

Numerical operations and descriptive statistics differ for each scale. For ordinal data, only non-parametric tests can be applied, and the most common descriptive statistic is the median. Ratio data, on the other hand, allows for a wide range of numerical operations, including addition, subtraction, multiplication, and division. Descriptive statistics for ratio data include measures such as mean, median, mode, range, and standard deviation.

The ordinal scale represents data with a rank order or hierarchy, where the values have a meaningful order but the differences between them may not be equal. Common examples of ordinal data include rankings, ratings, and Likert scale responses. Numerical operations such as addition and subtraction are not applicable to ordinal data since the differences between the ranks are not known. Therefore, only non-parametric tests, such as the Mann-Whitney U test or the Wilcoxon signed-rank test, can be used for analysis. The most appropriate descriptive statistic for ordinal data is the median, which represents the middle value in the ordered data set.

On the other hand, the ratio scale includes a true zero point, and the differences between values are meaningful and equal. Examples of ratio data include height, weight, time, and temperature measured on the Kelvin scale. Ratio data allow for a wide range of numerical operations, including addition, subtraction, multiplication, and division. Descriptive statistics commonly used for ratio data include measures such as the mean, which calculates the average of the data set, the median, which represents the middle value, the mode, which identifies the most frequently occurring value, the range, which shows the difference between the maximum and minimum values, and the standard deviation, which measures the variability of the data around the mean.

In summary, ordinal and ratio scales represent different levels of measurement in statistics. Ordinal data can only be analyzed using non-parametric tests, and the median is the most appropriate descriptive statistic. Ratio data, on the other hand, allow for a wider range of numerical operations and various descriptive statistics, including mean, median, mode, range, and standard deviation. Understanding the measurement scale of data is crucial for selecting appropriate statistical techniques and interpreting the results accurately.

a)  The probability of getting a red sedan is approximately 0.333 or 33.3%.

Explanation:

Probability of getting a red sedan:

Out of the 60 vehicles, there are 38 sedans, and we know that the rest are red. So, the number of red sedans is 38 - 18 = 20.

The probability of getting a red sedan is the ratio of the number of red sedans to the total number of vehicles:

P(red sedan) = 20/60 = 1/3 ≈ 0.333

Therefore, the probability of getting a red sedan is approximately 0.333 or 33.3%.

b)  The probability of getting a blue SUV is 0.3 or 30%.

Explanation:

Probability of getting a blue SUV:

Out of the 60 vehicles, there are 22 SUVs, and we know that 18 of them are blue.

The probability of getting a blue SUV is the ratio of the number of blue SUVs to the total number of vehicles:

P(blue SUV) = 18/60 = 3/10 = 0.3

Therefore, the probability of getting a blue SUV is 0.3 or 30%.

c)  The probability of getting an SUV given that it is red is approximately 0.778 or 77.8%.

Explanation:

Probability of getting an SUV given that it is red:

Out of the 60 vehicles, we know that 14 of the SUVs are red.

The probability of getting an SUV given that it is red is the ratio of the number of red SUVs to the total number of red vehicles:

P(SUV | red) = 14/18 ≈ 0.778

Therefore, the probability of getting an SUV given that it is red is approximately 0.778 or 77.8%.

The change in profit (ΔP) when the number of units (Δx) increases by 5, based on the given marginal profit function, is -18331.50

To find the change in profit (ΔP) when the number of units (Δx) increases by 5.

we need to evaluate the marginal profit function and multiply it by Δx.

The marginal profit function is given by dP/dx = 12.1(60 - 3x).

We are given the value of x as 121, so we can substitute it into the marginal profit function to find the marginal profit at that point.

dP/dx = 12.1(60 - 3(121))

= 12.1(60 - 363)

= 12.1(-303)

= -3666.3

Now, we can calculate the change in profit (ΔP) by multiplying the marginal profit by Δx, which is 5 in this case.

ΔP = dP/dx×Δx

= -3666.3 × 5

= -18331.5

Answer:

Step-by-step explanation:

The zeros are the values of t that make the factors zero.

  1 -t = 0   ⇒   t = 1

  8 +16t = 0   ⇒   t = -8/16 = -1/2

The equation is used to model height after the ball is thrown. We don't expect it to be a good model before the ball is thrown (t < 0), so the zero in that region is extraneous.

Only the positive zero is in the function's domain, so that is the only one that is meaningful.

__

When t = 0 (at the time the ball is thrown), the function value is ...

  h(0) = (1 -0)(8 +0) = 8

The ball is thrown from a height of 8 feet.

Charmaine pays a monthly fee of a dollars for her phone service, and she pays an additional b cents per minute of use. The least she has been charged in a month is c dollars.

Solution:The least amount of charges that Charmaine paid in a month is c dollars. It is given that the monthly fee of Charmaine's phone service is a dollars. So, the amount charged per minute is given as (c - a) cents.

So, the least number of minutes she has used her phone in a month is c - a b cents. We can write this as an inequality as below: \(b(c - a) ≤ 100c\),

where 100c is the least amount of charges in dollars she paid in a month.

This can be simplified as:\(bc - ab ≤ 100c\)  --(1)

Solving for c, we get: c ≤ (100 × b)/(100 - b × a)   --(2)

From this, it is clear that c is positive if b × a < 100.

Therefore, we can say that the possible numbers of minutes Charmaine has used her phone in a month is c minutes such that: c ≤ (100 × b)/(100 - b × a),

if b × a < 100.

Since c represents the least amount of charges paid in a month, it must be a non-negative number.

Therefore, we can say that the possible numbers of minutes Charmaine has used her phone in a month is c minutes such that: c = ⌈(100 × b)/(100 - b × a)⌉, if b × a < 100.

Here, ⌈x⌉ represents the smallest integer that is greater than or equal to x.  Therefore, the possible numbers of minutes she has used her phone in a month are: c = ⌈(100 × b)/(100 - b × a)⌉ if b × a < 100.

Answer:

The correct answer is -

x+2y = 23

2x+3y= 39

Step-by-step explanation:

given:

cost of family 1 = 23

number of adults in family one = 1

number of children = 2

cost of family 2 = 39

number of adults in family 1 = 2

number of children = 3

solution:

for the first condition of family one-

In this case, there is only one adult and 2 children and they paid 23 then if the adult cost is x and the children ticket cost is y then

number of adults*x+number of children*y = total cost

1*x + 2*y = 23

x+2y= 23 .......equation 1.

for family two:

In this case, there is two adult and 3 children and they paid 39 then if the adult cost is x and the children ticket cost is y then

number of adults*x+number of children*y = total cost

2*x + 3*y = 39

= 2x+3y = 39....... equation 2

thus, the correct equations are:

x+2y = 23

2x+3y= 39

The 95% confidence interval for the mean number of college credits completed is approximately 48.029 to 52.371.

To construct a 95% confidence interval for the mean number of college credits completed, we can use the formula:

CI = x ± z * (σ/√n)

Where:

CI represents the confidence interval

x is the sample mean (50.2 credits)

z is the z-score corresponding to the desired confidence level (95% confidence level corresponds to a z-score of approximately 1.96)

σ is the population standard deviation (8.3 credits)

n is the sample size (51 students)

Let's calculate the confidence interval:

CI = 50.2 ± 1.96 * (8.3/√51)

Using a calculator or software, we can find the standard error (σ/√n):

SE = 8.3/√51 ≈ 1.164

Now substitute the values into the formula:

CI = 50.2 ± 1.96 * 1.164

Calculating the upper and lower bounds of the confidence interval:

CI = (50.2 - 1.96 * 1.164, 50.2 + 1.96 * 1.164)

Simplifying the expression:

CI ≈ (48.029, 52.371)

Therefore, the 95% confidence interval for the mean number of college credits completed is approximately 48.029 to 52.371.

The requried first term of the sequence is $6.32.

Arithmetic progression is the series of numbers that have common differences between adjacent values

Here,
The amount of money Sally spends on breakfast each week forms an arithmetic sequence.

Let's use the formula for the sum of an arithmetic sequence to find the first term of the sequence. We know that Sally has already spent $31.64, which means that she has made 31.64/4.52 = 7 visits to the breakfast place. So the sum of the first 7 terms of the sequence is:

S₇ = 7/2 * (a₁ + a₇)

We know that a₇ = $4.52, so we can plug this into the formula and simplify

S₇ = 7/2 * (a₁ + 4.52)

a₁ = $6.32

Similarly, all the outcomes can be evaluated,
By the end of the year, Sally will have spent $891.36 on breakfast.
