Step-by-step explanation:

the probability that he found his dog. alive is 15%.

What is probability?

The chance of an event can be calculated using the probability formula by simply dividing the favourable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anything between 0 and 1, as the favourable number of outcomes can never exceed the total number of outcomes. Probability theory is a branch of mathematics that focuses on calculating the likelihood that an event will occur. Probability measures how likely something is to happen.

if he searched in a for two days and b for two days

P(A) = 0.4

P(B) = 0.6

P(Dn D-1 F-1)= n n+2

P(FnA, Sn, F-1) = 0.25

P(FB, S, F-1) = 0.15

Hence the probability that he found his dog. alive is 15%.

0.8133 is the probability  that a randomly chosen test taker will score between 560 and 640.

Probability is the possibility that something will happen, to put it simply. We can talk about the chance or likelihood of various outcomes when we don't know how an event will turn out. Events that follow a probability distribution are the subject of statistics.

Probability is a branch of mathematics that deals with numerical representations of how likely it is for an event to occur or for a proposition to be true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates that the event is impossible and 1 indicates certainty.

P(540< x 640)

=  P ( \(\frac{560 - 560}{90}\) < \(\frac{x - mu}{sigma}\) < \(\frac{640-560}{90}\) )

By resolving this, we will obtain a probability ranging from zero to triple zero. Therefore, the likelihood will be zero. Less than zero 89 minutes our chance of being zero is zero.

Answer:

C

Step-by-step explanation:

(a) The real discrete Fourier transform (DFT) is calculated for the given data set to analyze the helicopter's acoustic signature.

(b) To obtain the ck values and illustrate the relative size of each term in the Fourier series, we calculate the magnitude of each coefficient and plot their amplitudes on a bar graph against the corresponding frequency component, k.

To analyze the helicopter's acoustic signature, the real DFT is computed for the provided data set. The DFT transforms the time-domain measurements of acoustic pressure into the frequency domain, revealing the different frequencies present and their corresponding amplitudes. This analysis helps in understanding the spectral characteristics of the helicopter's acoustic signature and identifying prominent frequency components.

Using the Fourier series representation, the amplitudes (ck's) of the different frequency components in the Fourier series are determined. These amplitudes represent the relative sizes of each term in the series, indicating the contribution of each frequency component to the overall acoustic signature. By plotting the amplitudes on a bar graph, the relative strengths of different frequency components become visually apparent, enabling a clear comparison of their importance in characterizing the helicopter's acoustic signature.

The equation of the perpendicular line in slope intercept form is

y = (-3/4)x - 9/4.

The slope is defined as the rate of change of the y-axis with respect to

x-axis.

We know equation of a line in slope intercept form is y = mx + b, where slope = m and y-intercept = b.

We also know that perpendicular lines have a slope that is negative reciprocal of each other.

Given line is 8x - 6y = -5.

-6y = - 8x - 5.

-y = (-8/6)x - 5/6.

-y = (-4/3)x - 5/6.

y = (4/3)x + 5/6.

∴ Slope(m) = 4/3.

So, the line which is perpendicular has a slope(m) = -3/4 with points (1,-3).

∴ - 3 = (-3/4)(1) + b.

- 3 = -3/4 + b.

b = 3/4 - 3.

b = -9/4.

∴ The equation of the line is y = (-3/4)x - 9/4.

Option B. The value of the data set that measures the average value of all the elements of the data set. The mean is the average of all the values in the data set.

The mean is a measure of central tendency that is used to calculate the average value of a data set. In order to calculate the mean, all of the values in the data set are added together and then divided by the number of values in the data set. The mean is a good measure of central tendency to use when the data set is symmetrical.

This is because the mean is calculated by adding all of the values in the data set together and then dividing by the number of values in the data set. This gives each value in the data set an equal weight.

Таким образом, (X-2)(3x-1) = 0 можно переписать в виде двух уравнений:

X-2=0 или 3x-1=0

Решение для

X=2

Solving for x in the second equation, we get:

3x=1

x=1/3

Therefore, the possible values of X are X=2 and x=1/3.

The exact length of the curve is 8√3 + 16√6 units long.

We are given the parametric equations x = 3 + 6t² and y = 9 + 4t³. To determine the length of the curve, we can use the formula:

L = ∫[a, b] √(dx/dt)² + (dy/dt)² dt,

where a = 0 and b = 4.

Differentiating x and y with respect to t gives dx/dt = 12t and dy/dt = 12t².

Therefore, dx/dt² = 12 and dy/dt² = 24t.

Substituting these values into the length formula, we have:

L = ∫[0,4] √(12 + 24t) dt.

We can simplify the equation further:

L = ∫[0,4] √12 dt + ∫[0,4] √(24t) dt.

Evaluating the integrals, we get:

L = 2√3t |[0,4] + 4√6t²/2 |[0,4].

Simplifying this expression, we find:

L = 2√3(4) + 4√6(4²/2) - 0.

Therefore, the exact length of the curve is 8√3 + 16√6 units long.

The final answer is 8√3 + 16√6.

An example of an optimistic explanatory style would be viewing a bad grade on a test as something that doesn't often happen, will probably not affect your final grade, and is probably because you did not get enough sleep the night before the test.

An optimistic explanatory style involves interpreting negative events or outcomes in a positive and constructive manner. It involves attributing the causes of negative events to external, temporary, or specific factors rather than internal, permanent, or global factors.

In the given example, option (a) demonstrates an optimistic explanatory style. It suggests that the bad grade on the test is not a common occurrence ("something that doesn't often happen"), indicating that it is viewed as an isolated incident. Furthermore, it minimizes the impact of the bad grade by stating that it will probably not affect the final grade. Instead of attributing the cause to personal incompetence or intelligence.

The given expressions, when A=1, B=0, and C=1, X evaluates to 1.001; when A=B=C=1, X evaluates to 1.111; and when A=B=C=0, X evaluates to 0.000. These evaluations are based on the given values of A, B, and C, and the notation ¯¯¯¯¯¯BC represents the complement of BC.

To evaluate the expression X = A.¯¯¯¯¯¯BC, we substitute the given values of A, B, and C into the expression.

(a) For A = 1, B = 0, and C = 1:

X = 1.¯¯¯¯¯¯01

To find the complement of BC, we replace B = 0 and C = 1 with their complements:

X = 1.¯¯¯¯¯¯01 = 1.¯¯¯¯¯¯00 = 1.001

(b) For A = B = C = 1:

X = 1.¯¯¯¯¯¯11

Similarly, we find the complement of BC by replacing B = 1 and C = 1 with their complements:

X = 1.¯¯¯¯¯¯11 = 1.¯¯¯¯¯¯00 = 1.111

(c) For A = B = C = 0:

X = 0.¯¯¯¯¯¯00

Again, we find the complement of BC by replacing B = 0 and C = 0 with their complements:

X = 0.¯¯¯¯¯¯00 = 0.¯¯¯¯¯¯11 = 0.000

In conclusion, when A = 1, B = 0, and C = 1, X evaluates to 1.001. When A = B = C = 1, X evaluates to 1.111. And when A = B = C = 0, X evaluates to 0.000. The evaluation of X is based on substituting the given values into the expression A.¯¯¯¯¯¯BC and finding the complement of BC in each case.

A boxplot consists of several components including a box that shows the interquartile range (IQR) of the data, a line in the box representing the median, and "whiskers" that extend out from the box to show the range of the data.

If the box part of boxplot A is shorter in length than the box part of boxplot B, it suggests that the data in the first dataset (A) has a smaller interquartile range (IQR) compared to the data in the second dataset (B).

This means that the middle 50% of the data in dataset A is more tightly clustered together compared to the middle 50% of the data in dataset B. This can be due to the presence of outliers in the second dataset.

Boxplots are commonly used in statistical analysis and data visualization, but it is not used on a daily basis in every field. They are particularly useful in fields such as finance, biology, and engineering where large amounts of data need to be analyzed and visualized to draw insights and make decisions.

In these fields, they may be used daily or several times a week, depending on the specific use case and the data that needs to be analyzed. However, in other fields such as the arts, humanities, or some service industries, boxplots may not be used as frequently.

Answer:

Step-by-step explanation:

Part A:

car 1 => exponential function

car 2=> linear function

Part B:

car 1 => the function f(x) = 45,000 • (0.9)^x

car 2= > the function f(x) = 45,000 – (3,000)x

Part C:

after 13 years, the value of :

car 1 => 45,000 • (0.9)^13 = $ 11,438.40

car 2=> 45,000 – (3,000)(13) = $ 6,000

the difference is = 11,438.40 – 6,000= $ 5,438.40

she should buy 1

The function describing the value of car 1 is exponential and that of car 2 is linear. The function for car 1 is \(f(x) =\) \(45000 (9/10)^x\) and the function for car 2 is \(f(x) = 45000 - 3000x\).

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Part A :

If a function is linear, then the function values have equal differences.

If a function is exponential, the function values have equal ratios.

For car 1 :

36450 / 40,500 = 9/10

32805 / 36450 = 9/10

Values of car have equal ratios.

This is exponential function.

For car 2 :

39000 - 42000 = -3000

36000 - 39000 = -3000

Values of car have equal differences

This is linear function.

Part B :

The initial value of car is 45,000.

For car 1 :

\(f(x) =\) \(45000 (9/10)^x\)

f(1) = 40,500, f(2) = 36,450, ............

For car 2 :

\(f(x) = 45000 - 3000x\)

f(1) = 42,000, f(2) = 39,000, ..........

Part C :

For car 1 :

f(13) =  \(45000 (9/10)^{13\) = 11438.396

For car 2 :

f(13) = \(45000 - (3000*13)\) = 6000

There is a significant difference in the values of the car after 13 years. The value of the car 1 is greater.

Hence the value of the car 1 is described by an exponential function and that of car 2 by linear function. The value of car 1 is greater after 13 years.
