Answer: 25 + 12.5v ≥ 170

Step-by-step explanation:

We already have the 25 reward points; it also gives the information that she gets 12.5 points for each visit. Because we don't know the amount she has gone to the theater or will go we have to use a variable; 12.5v. When we add them, we get 25 + 12.5v. The inequality we use is ≥ because it says "at least". When this is used that means it has to be equal to or greater and that is why use that sign and get the full equation;

5 + 12.5v ≥ 170

The estimated product of 42,475 and 0.306 is 12,000.

To estimate the product of 42,475 and 0.306, we can round each factor to its greatest place.

42,475 rounds to 40,000 (rounded to the nearest thousand) since the digit in the thousands place is the greatest.

0.306 rounds to 0.3 (rounded to the nearest tenth) since the digit in the tenths place is the greatest.

Now we can multiply the rounded numbers:

40,000 × 0.3 = 12,000

Therefore, the estimated product of 42,475 and 0.306 is 12,000. This estimation provides a rough approximation of the actual product by simplifying the numbers and ignoring the decimal places beyond the tenths. However, it may not be as precise as the actual product obtained by performing the multiplication with the original, unrounded numbers.

If a matrix is diagonalizable then it is invertible is False.

A matrix can be diagonalizable but not invertible. For example, the zero matrix (a matrix where all entries are 0) is diagonalizable but not invertible.

What is diagonalizable metrix?

A diagonalizable matrix is a square matrix that can be transformed into a diagonal matrix through a similarity transformation. In other words, a matrix A is diagonalizable if there exists an invertible matrix P and a diagonal matrix D such that A = PDP⁻¹.

Geometrically, diagonalizable matrices represent linear transformations that stretch or shrink the space along a set of independent directions, which are called eigenvectors. The diagonal entries of the diagonal matrix D correspond to the eigenvalues of A, which represent the scaling factors along these directions.

Not all matrices are diagonalizable. A matrix is diagonalizable if and only if it has a sufficient number of linearly independent eigenvectors. In particular, symmetric matrices are always diagonalizable, and non-diagonalizable matrices are often associated with non-invertible linear transformations or defective geometric structures.

Confidence interval is the statistical range in which an unknown parameter is likely to fall. Here the confidence interval is (32.82, 38.38). So the choice 3 is correct.

Equation for confidence interval is,

 CI = X± Z × σ/√n

CI is the confidence interval

X is the mean

Z is the Z-value from the table for the chosen confidence level

σ is the standard deviation

n is the number of samples

Here X = 35.6 , σ = 8.2, n=18

Confidence level is 85%, Z-value corresponding to 85% confidence is 1.4395

CI = 35.6 ± 1.4395 × 8.2/√18

    = 35.6 ± 2.782

So the range will be (36.5- 2.782, 36.5 + 2.782)

                                  = ( 32.82, 38.38)

So the confidence interval is (32.82, 38.38)

Answer:

36/6

Step-by-step explanation:

12 x 3= 36.

2 x 3= 6.

Answer:

C. \(\frac{36}{6}\)

Step-by-step explanation:

Two values have frequency 2, so both are modes. They are 5 and 6. Therefore, the mode is 5 and 6.

Given measure: 3, 5, 4, 6, 10, 5, 6, 9, 2, 13.(D) To calculate \(x_2\), first we need to sort the data in ascending order: 2, 3, 4, 5, 5, 6, 6, 9, 10, 13

Now, we need to find the median, which is the middle value of the data. Since the data has even number of values, we will calculate the mean of middle two values, that is:(5+6)/2 = 5.5 Therefore, \(x_2 = 5.5\).\( \frac{2}{x}= \) To find the value of x, we will first cross-multiply and then take the reciprocal of both sides:\[\frac{2}{x} = y \Rightarrow 2 = xy \Rightarrow x = \frac{2}{y}\] Therefore, \( \frac{2}{x}= \frac{2}{y}\).

(b) To calculate Fried m, we will use the formula: \[f_m = L + \frac{(n/2 - F)}{f} \times c\]where L is the lower limit of the modal class, F is the cumulative frequency of the class preceding the modal class, f is the frequency of the modal class, c is the class interval, and n is the total number of values.

First, we will calculate the class interval:c = (upper limit of class - lower limit of class) = (7-6) = 1 Next, we will construct a frequency table to find the modal class:| Class Interval | Frequency ||-------------------|------------|| 2-3 | 1 || 3-4 | 1 || 4-5 | 1 || 5-6 | 2 || 6-7 | 2 || 7-8 | 1 || 9-10 | 1 || 10-11 | 1 || 13-14 | 1 |The modal class is the class with highest frequency.

Here, two classes have frequency 2, so both are modes. They are 5-6 and 6-7.

Therefore, L = 5, F = 2, f = 2, n = 10, and c = 1. Substituting the values, we get:\[f_m = L + \frac{(n/2 - F)}{f} \times c = 5 + \frac{(10/2 - 2)}{2} \times 1 = 7\] Therefore, Fried m = 7.

(c) To find the mode, we look for the value(s) with highest frequency. Here, two values have frequency 2, so both are modes. They are 5 and 6. Therefore, the mode is 5 and 6.

At this rate, the Boeing 747 airplane will fly approximately 1698.12 miles in 3 hours.

Distance traveled by a Boeing 747 in 3 hours: To determine the distance traveled by a Boeing 747 airplane in 3 hours, we can use the given information about its average speed and the time duration.

The average speed of the Boeing 747 airplane is calculated by dividing the total distance traveled by the time taken. In this case, the airplane flies 3,000 miles across the United States in 5.3 hours. Therefore, we can determine its average speed as follows:

Average speed = Total distance / Time taken

Average speed = 3,000 miles / 5.3 hours

Average speed ≈ 566.04 miles per hour (rounded to two decimal places)

Now, armed with the average speed, we can calculate the distance traveled in 3 hours by multiplying the average speed by the given time:

Distance traveled = Average speed × Time taken

Distance traveled = 566.04 miles per hour × 3 hours

Distance traveled ≈ 1698.12 miles (rounded to two decimal places)

Therefore, at this rate, the Boeing 747 airplane will fly approximately 1698.12 miles in 3 hours.

Answer:

(−4 -6.9 )= x, y  rotation 240 degree anti clockwise

Step-by-step explanation:

We are told radius = 8 so the center point or point of origin is 0.0

360/3 = 120 degree x 2 = 240 degree is where we need to be.

(8,0)  circulating anti clockwise = -8,0 at 180 = 180 degree.

This is 3 seconds.

We divide 8/3 to find the 4th and know it will be negative in the 3rd quadrant across the negative y axis, the lower and left point on the graph.

We know both are negative if going anti clockwise 240 degree.

We also know that the hands of a clock or mechanics of a mill cannot increase in length they shorten so they cannot be 8.7 even though triangles slants do increase this is independent of completing the lengths in a triangle. The lengths shorten.

-4 = x this is because it crosses -4 x axis to reach to -6.9 y coordinate.

Y= 6.9 as the length of 8 is shortened by 1.1 units between each 180 degree line we have 210deg (shows (-6.35, -2.4) also; 240 deg (-6.9, -4 ) and a 270 deg (this shows (0,8)

if 240/6.9 = 34% reduction

As 8 6.9 of 8 as a percentage = 86.25

As a ratio decrease we have 13.75% with the size of the coordinates at 240 degrees from 180 degrees the highest point is 270 degrees and is half again 1.1/2 = 0.55 increase in coordinates of y.

y would show -6.35 at 210 degrees and x would show 1.1 whole ratio change and show -2.4 at 210 degrees. The reason for this is that it is cutting the axis line and is a narrowing crossing for x axis shortly before 180 degree change.

The shortest point of the hand and central to 240 and 180 is 210 degree.

Student waiting times at bus stops are uniformly distributed between 12 and 28 minutes. The probability that a randomly selected student has a waiting time between 20 and 25 minutes is 0.313.

The waiting times at bus stops are uniformly distributed between 12 and 28 minutes. This means that any value between 12 and 28 minutes is equally likely to occur. In this case, we are interested in the probability of a waiting time between 20 and 25 minutes.

To calculate this probability, we need to determine the proportion of the total range that corresponds to the desired waiting time. The range of possible waiting times is 28 - 12 = 16 minutes. The desired waiting time range is 25 - 20 = 5 minutes.

Therefore, the probability of a waiting time between 20 and 25 minutes is equal to the desired waiting time range divided by the total range of possible waiting times:

P(20 ≤ X ≤ 25) = 5 / 16 ≈ 0.313

Rounding to 3 decimal places, the probability is approximately 0.313.

Answer:

Step-by-step explanation:

The required quarterly payment over a 13-year period at an interest rate of 9.6% per year, we can use the formula for calculating the future value of a series of equal payments.

This formula is known as the future value of an annuity. By plugging in the values for the number of periods, interest rate, and compounding frequency, we can determine the quarterly payment amount.The future value of an annuity formula is given by: FV = P * [(1 + r)^n - 1] / r

Where:
FV is the future value
P is the periodic payment
r is the interest rate per period
n is the number of periods

In this case, the interest rate is 9.6% per year, compounded quarterly. Since the compounding frequency matches the payment frequency, we can use the formula as is. The number of periods is 13 years, and since we are making quarterly payments, the number of periods will be 13 * 4 = 52.

Plugging in these values, we have:

FV = P * [(1 + 0.096/4)^(13*4) - 1] / (0.096/4)

To find the required quarterly payment, we can rearrange the formula to solve for P:

P = FV * (r / [(1 + r)^n - 1])

Substituting the known values:

P = FV * (0.096/4) / [(1 + 0.096/4)^(13*4) - 1]

Evaluating this expression will give us the required quarterly payment. Remember to round the answer to the nearest cent as specified.

To calculate the probability of properly describing at least three of your five main points, we need to consider the binomial distribution.

The probability of properly describing a point is 1 - 0.3 = 0.7 (assuming a 30% failure probability). Using the binomial distribution formula, we can calculate the probability of getting exactly three, four, or five successes (properly describing the points) out of five trials: P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5). P(X = k) = C(n, k) * p^k * (1 - p)^(n - k).  Where: n = number of trials (5). k = number of successes (3, 4, or 5). p = probability of success (0.7). Calculating the probabilities: P(X = 3) = C(5, 3) * 0.7^3 * (1 - 0.7)^(5 - 3). P(X = 4) = C(5, 4) * 0.7^4 * (1 - 0.7)^(5 - 4). P(X = 5) = C(5, 5) * 0.7^5 * (1 - 0.7)^(5 - 5). Finally, summing up these probabilities will give us the answer: P(X ≥ 3) = P(X = 3) + P(X = 4) + P(X = 5). (b) The mean and standard deviation of the number of jokes you tell can be calculated using the Poisson distribution, given an average rate of one joke per minute. The Poisson distribution is appropriate when events occur randomly and independently at a constant rate. For a Poisson distribution, the mean and standard deviation are equal to the rate parameter (λ). In this case, the mean and standard deviation of the number of jokes you tell per minute is 1. Since the pitch lasts six minutes, the mean and standard deviation of the total number of jokes you tell in the pitch will be: Mean = 1 * 6 = 6.  Standard Deviation = sqrt(1 * 6) = sqrt(6). (c) To find the probability that your first joke comes at least two minutes into your pitch, we need to calculate the complement of the probability that your first joke comes within the first two minutes. The probability that your first joke comes within the first two minutes is 2 jokes / 6 minutes = 1/3. Therefore, the probability that your first joke comes at least two minutes into your pitch is 1 - 1/3 = 2/3.(d) The mean and standard deviation of the time until the investors tell you to stop joking can be calculated using the exponential distribution, given the average rate of one joke per minute. The exponential distribution models the time between events in a Poisson process. For an exponential distribution, the mean (μ) is equal to the reciprocal of the rate parameter (λ), and the standard deviation (σ) is also equal to the reciprocal of the rate parameter (λ). In this case, the rate parameter λ is 1 joke per minute, so the mean and standard deviation of the time until the investors tell you to stop joking is 1/1 = 1 minute.

Please note that the question regarding the probability of the first joke coming at least two minutes into your pitch was already answered in part (c).
