Probability is a measure of the likelihood that a specific event will occur in a random experiment.

What is the Probability?

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

In other words, the probability is a number that represents the chance or chance of an event occurring out of all possible outcomes.

It is expressed as a fraction, decimal, or percentage.

For example, if there is a 50% chance of rain, this means that the probability of rain is 0.5 or 1/2.

Probability is important in decision-making, risk assessment, and mathematical modeling. It helps to quantify uncertainty and provides a way to assess the likelihood of different outcomes.

Hence, Probability is a measure of the likelihood that a specific event will occur in a random experiment.

The random variable's pdf is f(x) = (3/8) x^2 , x ∈ [0, 2].

Finding the normalizing constant that equals the integral of the pdf over the support of the random variable yields the constant in the pdf (probability density function).

The random variable's support is the interval [0, 2]. The normalizing constant can be calculated as follows:

∫_0^2 x^2 dx = [x^3/3]

_0^2 = (8/3) - (0) = 8/3

So, in the pdf, the constant is 1/(8/3) = 3/8, rounded to the second decimal place.

As a result, the random variable's pdf is:

f(x) = (3/8) x^2 , x ∈ [0, 2].

The required distance between the two given cities using the distance formula is 93 miles.

Distance is the sum of an object's movements, regardless of direction.

The distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

Learn how to apply the Pythagorean theorem to find the distance between two points using the distance formula.

The Pythagorean theorem can be rewritten as d=(((x 2-x 1)2+(y 2-y 1)2) to calculate the separation between any two locations.

So, we have the points:

(53, 17) and (123, 78)

Distance formula:

d = √(x2-x1)² + (y2-y1)²

Now, calculate as follows:

d = √(x2-x1)² + (y2-y1)²

d = √(123-53)² + (78-17)²

d = √(70)² + (61)²

d = √(4,900) + (3,721)

d = √8,621

Answer:

[tex]x=\dfrac{20}{3}\; \sf cm[/tex]

Step-by-step explanation:

If a line is parallel to a side of a triangle and intersects the other two sides, then this line divides those two sides proportionally.

Applying the side-splitter theorem:

[tex]\implies \dfrac{3}{5}=\dfrac{4}{x}[/tex]

Cross multiply:

The value of vector (2u + v) is -5i +8k +5j and the value of u.v is -7.

Geometrical objects with magnitude and direction are called vectors. A line with an arrow pointing in its direction can be used to represent a vector, and the length of the line corresponds to the vector's magnitude.

As a result, vectors are depicted as arrows and have starting and ending points.

The value of the vector (2u + v) is calculated as:-

E = (2u + v)

E = 2 ( -i + 5k) +( -3i + 5j -2k)

E = -2i +10k -3i +5j -2k

E = -5i + 5j + 8k

The formula is: f(x) = 2 * sin(x * 5 / 2π) + 5

A = 5 - 3 = 2, the amplitude of the function.

Since (0,3) is the minimum, the midline is at y = 3 + 2 = 5, the average value of the maximum and minimum.

Let "c" be the shift, so the equation of the midline is y = 5 + c.

At x = 5, the function intersects its midline, so 5 = 5 + c.

Therefore, c = 0.

The period of the function is 2π / b, where b is the number of radians for one complete cycle.

Since the function intersects its midline at (5,5), b = 5.

Therefore, the period of the function is 2π / 5.

The formula of the sinusoidal function is:

f(x) = A * sin(b * (x - c)) + d,

Type of variable: quantitative-discrete

Mean mercury level in fish of all Florida lakes: Parameter of interest

Statistic that will be used: Mean (arithmetic average) of the mercury levels in the sample of 56 fish from the lake.

The sample of 56 fish from a randomly selected Florida lake represents a portion of the population of fish in all Florida lakes. The mean mercury level in these 56 fish represents a statistic, which is an estimate of the population parameter, the mean mercury level in fish of all Florida lakes.

The mean (arithmetic average) is used as the statistic because it summarizes the data by finding the central tendency of the mercury levels in the sample of 56 fish. It is a suitable measure to describe the typical mercury level in the fish from the lake because it takes into account all the observations in the sample.

Since mercury levels are measured in numerical values, the variable "mean mercury level" is quantitative. Since it is a continuous measurement, it is also a continuous quantitative variable.

In summary, the sample and the mean mercury level in the sample of 56 fish are used to make inferences about the population and its parameter, the mean mercury level in fish of all Florida lakes. The mean is used as the statistic to summarize the data and describe the central tendency of the mercury levels in the sample.

Answer:

This is the equation of the normal line at the point (2, 1) on the ellipse (x^2)/4 + y^2 = 2.

Step-by-step explanation:

The equation of the ellipse is (x^2)/4 + y^2 = 2. To find the equation of the normal line at the point (2, 1), we first need to find the slope of the tangent line at that point. To do this, we can use the formula for the slope of a tangent line:

slope = -(d/dx)(f(x)) / (d/dy)(f(y))

Where f(x) and f(y) are the equations of the ellipse.

So,

slope = -(x/2)/y = -x/2y

Now we can substitute the point (2, 1) into the equation for the slope:

slope = -(2/2)/1 = -1

We know that the slope of the normal line is the negative reciprocal of the slope of the tangent line, so the slope of the normal line is 1.

To find the equation of the normal line, we can use the point-slope form of a line:

y - y1 = m(x - x1)

Where (x1, y1) is the point on the line and m is the slope.

So,

y - 1 = 1(x - 2)

Simplifying, we get:

y = x - 1

This is the equation of the normal line at the point (2, 1) on the ellipse (x^2)/4 + y^2 = 2.

At the beginning of 2072 B.S., the population of the town was X.

Assuming the population growth rate is 10%, the population at the end of 2074 B.S. will be (X + 10% of X) + (X + 10% of X + 10% of X) = 1.1X + 1.1(1.1X) = 2.21X.

Therefore, the population of the town at the end of 2074 B.S. will be 2.21X. This is based on a linear population growth rate of 10% over two years. It is possible that the growth rate may not be constant, so the actual population may be slightly different.

In order to get a better estimate of the population at the end of 2074 B.S., it is important to consider other factors such as birth and death rates, migration, and economic and social factors.

For example, if the town is experiencing an influx of migrants, then the population growth rate may be higher than the estimated 10%. On the other hand, if the town faces an economic recession or job losses, then the population growth rate may be lower than the estimated 10%.

Overall, the population of the town at the end of 2074 B.S. is estimated to be 2.21X, based on a linear population growth rate of 10% over two years. However, this estimate may be slightly different depending on the other factors mentioned above.

The probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice is approximately 0.5949 (rounded off to third decimal place).

To find the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice, we need to find the cumulative distribution function (CDF) of a normal distribution with a mean of 500 and standard deviation 4.

Using the Z-score formula, we can calculate the Z-score for 499 ml of juice: (499-500)/4 = -0.25

Next, we use a standard normal table to find the probability of a Z-score less than -0.25, which is 0.4051.

Finally, we use the CDF formula for a normal distribution to find the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice:

P(X < 499) = 1 - P(X >= 499) = 1 - 0.4051 = 0.5949

Therefore, the probability that fewer than 10 cans in a sample of 60 contain less than 499 ml of juice is approximately 0.5949 (rounded off to the third decimal place).
