The prοbability that a persοn chοsen at randοm has nο credit cards is:

P(nο credit cards) = 8/20 = 0.4 οr 40%

Prοbability is a measure οf the likelihοοd οr chance οf an event οccurring. It is a number between 0 and 1, with 0 representing an impοssible event and 1 representing a certain event. The prοbability οf an event is calculated by dividing the number οf ways the event can οccur by the tοtal number οf pοssible οutcοmes.

Since we knοw the tοtal number οf credit cards and the number οf peοple whο οwn them, we can find the prοbability that a persοn chοsen at randοm has nο credit cards by dividing the number οf peοple with nο credit cards by the tοtal number οf peοple in the grοup:

Number οf peοple with nο credit cards: 8

The balance of the loan after 2 monthly payments is $246,778 (rounded to the nearest dollar).

Compounding refers to the process of earning interest on both the principal amount and the interest earned on that principal over time. In other words, it is the process of reinvesting earnings so that those earnings can also earn money, creating a compounding effect.

Compound interest is calculated on the initial principal amount and also on the accumulated interest of previous periods. This means that the interest earned in each period is added to the principal, and the interest for the next period is calculated on the new total.

To find the balance of the loan after 2 monthly payments, we first need to calculate the total number of payments over the life of the loan. Since the loan is paid over 25 years with monthly payments, the total number of payments is:

25 years x 12 months/year = 300 months

Next, we can use the formula for the present value of an ordinary annuity to calculate the remaining balance after 2 monthly payments. The formula is:

PV = PMT x ((1 - (1 + r)⁻ⁿ) / r)

where PV is the present value or remaining balance, PMT is the monthly payment, r is the monthly interest rate, and n is the total number of payments.

The monthly interest rate is the annual interest rate divided by 12, so in this case, it is:

6% / 12 = 0.005

Plugging in the values, we get:

PV = $1,610.75 x ((1 - (1 + 0.005)⁻³⁰⁰) / 0.005)

PV = $240,902.43

This is the remaining balance after 2 monthly payments. To find the balance after the second monthly payment, we need to subtract two monthly payments from the original loan amount:

$250,000 - ($1,610.75 x 2) = $246,778.50

Therefore, the balance of the loan after 2 monthly payments is $246,778 (rounded to the nearest dollar).

The equation that relates C to R, given the number of cars that Latoya has to rent and the number of cars left after renting, is C = 23 - R.

The number of cars left after 8 cars have been rented is 15 cars.

To write an equation relating the number of cars left (C) to the number of cars rented (R), we can use the total number of cars available (23) and subtract the number of cars rented:

C = 23 - R

Now, to find the number of cars left after renting 8 of them, we can substitute R = 8 into the equation:

C = 23 - 8

C = 15

So, Latoya would have 15 cars left after renting 8 of them.

the probability of picking 3 red marbles if each marble is NOT returned to the bag before the next marble is picked is14/285.

Probability is a measure of the likelihood or chance that a particular event will occur, expressed as a number between 0 and 1. A probability of 0 means that the event is impossible, while a probability of 1 means that the event is certain.

After the first red marble is drawn, there will be 19 marbles left in the bag, of which 7 are red.

So, the probability of picking a red marble on the second draw, given that the first marble was red and not returned to the bag, is 7/19.

Similarly, after the second red marble is drawn, there will be 18 marbles left in the bag, of which 6 are red.

So, the probability of picking a red marble on the third draw, given that the first two marbles were red and not returned to the bag, is 6/18 or 1/3.

Therefore, the probability of picking 3 red marbles in a row is:

Statistical inference is the process of using data from a sample to make generalizations or draw conclusions about a larger population.

Based on the sample data, assumptions are made about the fundamental traits of the population, and the uncertainty in those assumptions is quantified using statistical techniques.

Because it enables us to forecast the future and make judgements based on incomplete data, statistical inference is crucial. For instance, with a sample of data, it enables us to confidently estimate population parameters such as averages and proportions. This can be helpful in a variety of contexts, including marketing analysis, surveys of public opinion, clinical trials, and manufacturing quality control.

By comparing the results of several groups or treatments, statistical inference also enables us to assess the efficacy of interventions or treatments.This can inform decisions about which treatments are most effective or which interventions should be implemented.

An arithmetic progression (AP) is a series of numbers where each term is created by multiplying the previous term by a fixed constant (also known as the common difference). In other words, an AP is a set of numbers whose any two consecutive terms' differences are always the same.  For instance, the mathematical progression 2, 5, 8, 11, and 14 has a common difference of 3. An algebraic progression generally takes the following form: "a," "a+d," "a+2," "a+3,"... where a denotes the sequence's first word, d is its common difference, and the ellipsis (...) denotes that the series is infinite. Mathematical progressions are crucial and are utilised in many disciplines, such as algebra, calculus, and number theory.

given

We can use the arithmetic sum formula to determine the sum of the mathematical series with initial term a=2 and common difference d=3:

Sn = (n-1)d/2(2a + n-1)a

where Sn is the sequence's initial n phrases added together.

The value of the nth term can be determined by substituting n into the arithmetic calculation, a = 3n - 1:

We can use the following words to get the value of n for the final term in the sequence:

a n = 14 = 3n - 1

3n = 15

n = 5

Answer:

Let's use "x" to represent the number of animals in the shelter.

The fixed weekly expenses of the animal shelter are $750, and each animal costs an additional $6 per week. Therefore, the total weekly expenses of the animal shelter would be:

Total Weekly Expenses = Fixed Weekly Expenses + (Cost Per Animal * Number of Animals)

Total Weekly Expenses = 750 + 6x

We know that during the winter month, the weekly expenses are at most $900. So we can write the following inequality to represent this situation:

Total Weekly Expenses ≤ 900

Substituting the expression for the total weekly expenses, we get:

750 + 6x ≤ 900

Simplifying this inequality, we get:

6x ≤ 150

Dividing both sides by 6, we get:

x ≤ 25

Therefore, the inequality that represents the number of animals in the shelter for expenses to be at most $900 a week is:

x ≤ 25

This means that the shelter can have at most 25 animals during the winter month for the expenses to be within the limit of $900 a week.

Therefore, the probability that a randomly selected light bulb will last between 750 and 900 hours is 0.4772, or 47.72%.

What is deviation?

The degree to which anything deviates from a norm or expected value is referred to as its deviation. The deviation of a collection of data from the average or mean value in statistics is a measurement of how dispersed the data are. Absolute deviation and standard deviation are the two different types of variance.

We may determine that, according to the 68-95-99.7 rule, 68% of the data is within one standard deviation of the mean, 95% is within two standard deviations, and 99.7% is within three standard deviations.

Here, we're trying to determine the likelihood that a randomly chosen light bulb would live between 750 and 900 hours. One standard deviation to two standard deviations above the mean define this range.

First, we need to standardize the values using the formula:

z = (x - μ) / σ

where x is the value, we want to standardize, μ is the mean, and σ is the standard deviation.

For x = 750

z = (750 - 750)/75 = 0

For x = 900

z = (900 - 750)/75 = 2

Now we need to find the area under the standard normal distribution curve between z = 0 and z = 2. We can use a table or calculator to find this area, which is approximately 0.4772.

A. To construct a grouped frequency distribution for the given data, we first need to determine the range of the data:

Range = Maximum value - Minimum value

Range = 39 - 5

Range = 34

Next, we need to decide on the width of each class interval. A common rule is to choose the number of classes to be between 5 and 20, and then choose a class width that is a convenient number. In this case, we will choose 8 classes and a class width of 5.

Class width = Range / Number of classes

Class width = 34 / 8

Class width ≈ 4.25

We can round up the class width to 5 to get a convenient number. The class intervals are:

5 - 9.99

10 - 14.99

15 - 19.99

20 - 24.99

25 - 29.99

30 - 34.99

35 - 39.99

40 - 44.99

Next, we count the number of observations that fall into each class interval. This gives us the frequency of each interval. The grouped frequency distribution is:

Class Interval Frequency

5 - 9.99 5

10 - 14.99 8

15 - 19.99 9

20 - 24.99 16

25 - 29.99 7

30 - 34.99 6

35 - 39.99 1

40 - 44.99 0

B. To draw the histogram, frequency polygon, and cumulative frequency curves, we first need to calculate the cumulative frequencies. The less than cumulative frequency is the running total of the frequencies up to each class interval, while the more than cumulative frequency is the running total of the frequencies from each class interval to the end.

Class Interval Frequency Less than Cumulative Frequency More than Cumulative Frequency

5 - 9.99 5 5 62

10 - 14.99 8 13 57

15 - 19.99 9 22 49

20 - 24.99 16 38 40

25 - 29.99 7 45 24

30 - 34.99 6 51 17

35 - 39.99 1 52 11

40 - 44.99 0 52 10

The measure of ∠U to the nearest degree using Cosine rule is 154⁰.

The Cosine Rule says that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

The law of cosines states that:

c² = a² + b² - 2ab cos(C)

where a, b, and c are the lengths of the sides of the triangle, and C is the angle opposite to the side c.

According to our figure,

UW²=UV²+VW²-2(UV).(VW).Cos V

UW²=1²+2.8²-2(1)(2.8).Cos 17⁰

UW²=3.49

Taking square root on both sides, we get

UW=√3.49

UW=1.87

Now,

Cos U=(UW²+UV²-VW²)/2(UV)(UW)

Cos U=(1.87²+1²-2.8²)/2·(1)·(1.87)

Cos U=-3.34/3.74

Cos U=-0.89

There are approximately 720 blue balls, 1080 red balls, 360 green balls, 540 orange balls, and 900 yellow balls in the bin.

To predict how many of each color are in the bin, we can assume that the ratio of each color in the bin is the same as the ratio in the sample of 20 balls.

First, we calculate the total number of each color in the sample:

Blue: 4 balls

Red: 6 balls
