Answers:

Gender = categorical, nominal variable

Sleep length = numerical, continuous

Bedtime = categorical, ordinal

Number of countries visited = numerical, discrete

Scale of dreading semester = categorical, ordinal

=========================

Explanation:

Gender is categorical because there are two categories or labels, male or female. It is nominal because we simply attach names to each label and we can't sort them or order them from highest to lowest. There is no ranking for gender.

Sleep length is numerical as it deals with numbers. I put continuous because someone could write 2.5 hours or 3.75 hours. If whole numbers are only allowed, then the variable would be discrete.

The bedtime portion is categorical as each time slot is a category. Like with the first part, they are simply labels. We can order them however from earliest to later on, which is why this variable is ordinal.

The number of countries visited is numeric as expected, and it's also discrete because we can't visit 0.1 of a country. By "visit", I mean step foot in any part of the country for any length of time. It does not mean you have to explore every square inch of the territory.

The last part is categorical and ordinal. The scale ranking is ordered for us from 1 to 5. Despite the fact we have numbers here, the data is not numerical as the numbers 1 through 5 represent labels of "very little" through "a lot".

A bank makes a car loan of $ 29,500  at 6.4 % interest and with a loan period of 5 years. The monthly payment for your car loan is $575.82.

The formula for calculating the monthly payment of a car loan is:

Monthly payment = Principal amount × Interest rate × (1 + Interest rate)^Number of payments / [(1 + Interest rate)^Number of payments - 1]  .....(a)

In your case, the principal amount is $29,500, the interest rate is 6.4%, and the number of payments is 60 (5 years × 12 months).

Plugging these values into the formula(a), we get:

Monthly payment = $29,500 × 0.064 × (1 + 0.064)^60 / [(1 + 0.064)^60 - 1]

= \$575.82

Therefore, the monthly payment for your car loan is $575.82.

Answer:

Step-by-step explanation:

Big circle:

R = radius = diameter ÷2 = 42 ÷ 2 = 21 cm

Area of big circle= πR²

                            \(=\dfrac{22}{7}*21*21=22*3*21\\\\\\= 1386 \ cm^{2}\)

Small circle:

Diameter of small circle  = radius of big circle = 21 cm

r = 21/2 = 10.5 cm

Area of small circle = πr²

                                \(=\dfrac{22}{7}*10.5*10.5 = 22 * 1.5*10.5\\\\\\= 346 .5 \ cm^{2}\)

Area of shaded region = area of big circle - area of small circle

= 1386 - 346.5

The diameter of the sphere is 14 cm.

Sphere is a three dimensional object , it has no edges or vertices and is round in shape.

The surface area of the sphere is given by 4πr²

As radius = diameter /2

Surface area =  4π r²

196 π = 4π *(d/2)²

196/4 = d²/4

49 *4 = d²

d = 14 cm

Therefore the diameter of the sphere is 14 cm.

The correct hypothesis statement would be:

H0: μ = 45 (null hypothesis)

H1: μ ≠ 45 (alternative hypothesis)

The null hypothesis (H0) represents the current belief or assumption, and states that the population mean is equal to a specific value, which in this case is 45 minutes. The alternative hypothesis (H1) is the opposite of the null hypothesis, and states that the population mean is not equal to 45 minutes.

This hypothesis statement assumes a two-tailed test, where the researcher is interested in detecting any significant deviation from the hypothesized mean in either direction. This means that the researcher will reject the null hypothesis if the sample mean is either significantly higher or significantly lower than 45 minutes, based on the level of significance chosen for the test.

Option D correctly states the null hypothesis but incorrectly states the alternative hypothesis. Option A correctly states the alternative hypothesis but incorrectly states the null hypothesis. Option C states a one-tailed alternative hypothesis, which is only appropriate if the researcher has a specific direction in mind (e.g., if they expect the average time to be longer than 45 minutes).

The wage of 2001 in terms of wage in 2012 is option A $14.97

Given,

Mack's wages in 2001 = $7 per hour

Mack's wages in 2012 = $12 per hour

The CPI in 2001 = 94

The CPI in 2012 = 201

We have to fins the wage of 2001 in terms of wage in 2012;

CPI;- Consumer Price Index

The CPI is calculated by the Bureau of Labor Statistics each month using a sample of 94,000 prices. To determine the overall change in prices, the index for each good or service is weighted according to its share of recent consumer spending.

Here,

The wage of 2001 in terms of wage in 2012 = (CPI in present year / CPI in past year) x Wage of earlier year

= (201 / 94) x 7

= 14.97

There are 60 minutes in one hour. 3 hours would be equal to 180 minutes.

How many minutes are in 3 hours?

To convert hours to minutes, we need to consider that there are 60 minutes in one hour. In this case, since we have 3 hours, we can multiply 3 by 60 to get the equivalent number of minutes.

By performing the calculation, we find that 3 hours is equal to 180 minutes. This means that if you were to measure a time period of 3 hours, it would be equivalent to 180 minutes on the clock.

Understanding this conversion is useful when dealing with time-related calculations, such as scheduling events or determining durations. It allows us to easily switch between hours and minutes to represent time in different formats.

3 hours can be expressed as 180 minutes, demonstrating the relationship between hours and minutes in the context of time measurement.

Answer: a. To create a relative frequency table, first find the frequency of each number of jobs by counting how many times each number appears in the data set. Then, divide each frequency by the total number of students in the class to find the relative frequency (or percent) of each number of jobs. The table would look something like this:

Number of jobs Frequency Relative frequency (percent)

0                        4                                  20%

1                         7                                 35%

2                         7                                 35%

3                         3                                 15%

b. To find the mean of a data set, add up all the values and divide by the number of values. In this case, the mean would be calculated like this: (1+2+0+0+1+3+1+2+1+2+1+0+3+1+2+3+1+0+1+2+0+2) / 22 = 1.3636363636363635

c. To find the median of a data set, first put the values in order from least to greatest. If the number of values is odd, the median is the middle value. If the number of values is even, the median is the average of the two middle values. In this case, the values in order are: 0, 0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3. Since there are 22 values, the median is the average of the 11th and 12th values, which is (1+1) / 2 = 1

d. To find the mode of a data set, look for the value that appears most often. In this case, the mode is 1, because it appears 7 times, more than any other value.

e. To find the range of a data set, subtract the smallest value from the largest value. In this case, the range would be 3 - 0 = 3.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence.

A sequence in mathematics is an ordered collection of numbers that is typically defined by a formula or rule. Every number in the series is referred to as a term, and its location within the sequence is referred to as its index. Depending on whether the list of terms stops or continues indefinitely, sequences can either be finite or infinite. By their patterns or uniformity, sequences can be categorised, and the study of sequences is crucial to many areas of mathematics, such as calculus, number theory, and combinatorics. Mathematical, geometrical, and Fibonacci sequences are a few examples of popular sequence types.

given

The sequence's terms are all different by 7 (i.e., 12 - 5 = 19 - 12 = 26 - 19 =... = 7).

The following is a definition of a recursive formula for the nth element of the sequence:

a 1 = 5 (the first term of the series is 5) (the first term of the sequence is 5)

For n > 1, each term is derived by adding 7 to the preceding term, so a n = a n-1 + 7.

Thus, beginning with a 1 = 5, the formula a n = a n-1 + 7 can be used to recursively find the nth term of the sequence. For instance, we have

a_2 = a_1 + 7 = 5 + 7 = 12

a_3 = a_2 + 7 = 12 + 7 = 19

a_4 = a_3 + 7 = 19 + 7 = 26
