Step-by-step explanation:

A triangle represents 1/4 of the trapezoid, a diamond represents 1/2 of the trapezoid, and a hexagon represents 1/1 of the trapezoid.

Each shape represents a different part of the overall trapezoid.

The triangle represents 1/4 of the full trapezoid. This is because the trapezoid has four triangles, all of the same size. So each triangle is 1/4 of the whole trapezoid. The diamond represents 1/2 of the full trapezoid. This is because the trapezoid has two diamonds, each of the same size. So each rhombus is 1/2 of the whole trapezoid.

The hexagon represents 1/1 of the whole trapezoid. This is because the trapezoid has only one hexagon, which is the same size as the entire trapezoid. So the hexagon is 1/1, the whole trapezoid.

In summary, a triangle represents 1/4 of a trapezoid, a diamond represents 1/2 of a trapezoid, and a hexagon represents 1/1 of a hexagon. Using these fractions, we can determine the value of each shape relative to the overall trapezoid.

The answer is P(x < 85) = 0.1587

Given that the random variable x is normally distributed with mean μ=90 and standard deviation σ=5. We need to find the probability P(x < 85).

Normal Distribution

The normal distribution refers to a continuous probability distribution that has a bell-shaped probability density curve. It is the most important probability distribution, particularly in the field of statistics, because it describes many natural phenomena.

P(x < 85)Using z-score:

When a dataset follows a normal distribution, we can transform the data using z-scores so that it follows a standard normal distribution, which has a mean of 0 and a standard deviation of 1, as shown below:z = (x - μ) / σ = (85 - 90) / 5 = -1P(x < 85) = P(z < -1)

We can find the area under the standard normal curve to the left of -1 using a z-table or a calculator.

Using a calculator, we can use the normalcdf function on the TI-84 calculator to find P(z < -1). The function takes in the lower bound, upper bound, mean, and standard deviation, and returns the probability of the z-score being between those bounds, as shown below:

normalcdf(-10, -1, 0, 1) = 0.1587

Therefore, P(x < 85) = P(z < -1) ≈ 0.1587 (to four decimal places).Hence, the answer is P(x < 85) = 0.1587 (rounded to four decimal places).

Answer:

Scale factor = 4

Step-by-step explanation:

Scale factor = \(\frac{\text{Dimension of the larger (Image) triangle}}{\text{Dimension of the smaller (Preimage) triangle}}\)

From the given triangle,

Length of one side of the larger triangle = 8 units

Length of the corresponding side of the smaller triangle = 2 units

By substituting the values in the formula of scale factor,

Scale factor = \(\frac{8}{2}\)

Scale factor = 4

a) To find the probability that the 4th car arrives before 11 minutes, we can use the Poisson probability formula:

P(X = k) = (e^(-λ) * λ^k) / k!

where λ is the average rate of arrivals (X cars per minute) and k is the number of arrivals.

In this case, we want to find P(X = 4), given that the arrival rate is X cars per minute.

P(X = 4) = (e^(-X) * X^4) / 4!

To calculate the probability as a summation, we can express it as the sum of probabilities for each possible arrival rate (X cars per minute):

P(4th car arrives before 11 minutes) = Σ[(e^(-X) * X^4) / 4!] for all X > 0

b) To find the probability that the 1st car arrives after 2 minutes, the 3rd car arrives before 6 minutes, and the 4th car arrives between time 6 and 11 minutes, we need to consider the arrival times of each car individually.

Let A1, A2, A3, and A4 represent the arrival times of the 1st, 2nd, 3rd, and 4th cars, respectively.

Given:

- The 1st car arrives after 2 minutes: P(A1 > 2) = 1 - P(A1 ≤ 2) = 1 - (1 - e^(-X*2))

- The 3rd car arrives before 6 minutes: P(A3 < 6) = 1 - e^(-X*6)

- The 4th car arrives between 6 and 11 minutes: P(6 < A4 < 11) = P(A4 > 6) - P(A4 > 11) = e^(-X*6) - e^(-X*11)

The overall probability can be calculated by multiplying these individual probabilities together:

P(1st car arrives after 2 min, 3rd car arrives before 6 min, 4th car arrives between 6 and 11 min) = P(A1 > 2) * P(A3 < 6) * P(6 < A4 < 11)

Answer:

Step-by-step explanation:

The relationship between period and frequency is that they are inversely proportional to each other. In simpler terms, as the period of a wave or oscillation increases, its frequency decreases, and vice versa.

Mathematically, this relationship can be expressed using the formula: Frequency (f) = 1 / Period (T). Likewise, Period (T) = 1 / Frequency (f).To understand this relationship, let's first define the terms. Period (T) refers to the time it takes for one complete cycle of a wave or oscillation to occur. On the other hand, frequency (f) is the number of complete cycles that occur within a specific time interval, usually one second, and is measured in Hertz (Hz).

When a wave or oscillation has a longer period, it takes more time to complete one cycle, which means fewer cycles can occur within a given time frame. Consequently, the frequency is lower. Conversely, when the period is shorter, more cycles can fit within the same time frame, resulting in a higher frequency.

Step-by-step explanation:

L×W=A

The hydrostatic force on the window is approximately 47,481 Newtons.

We can use the formula for hydrostatic force, which is:

F = ρghA

where F is the hydrostatic force, ρ is the density of the fluid (water in this case), g is the acceleration due to gravity, h is the depth of the window, and A is the area of the window.

First, we need to find the area of the window. Since the window is a semi-circle with diameter 70 centimeters, the radius is 35 centimeters, and the area is:

A = (π/2)r^2

= (π/2)(35 cm)^2

= 1225π/2 cm^2

Next, we need to convert the depth of the window to meters:

h = 2.5 m

We also need the density of water, which is approximately:

ρ = 1000 kg/m^3

Finally, we need the acceleration due to gravity, which we can assume is:

g = 9.8 m/s^2

Now we can plug these values into the formula:

F = ρghA

= (1000 kg/m^3)(9.8 m/s^2)(2.5 m)(1225π/2 cm^2)

≈ 47,481 N

Therefore, the hydrostatic force on the window is approximately 47,481 Newtons.

True. Marginal cost refers to the additional cost incurred by producing one more unit of output.

Since the production of one more unit requires the use of additional variable factors of production (such as labor or raw materials), marginal cost always reflects the cost of those variable factors. Fixed costs, on the other hand, do not change with changes in output and are not included in marginal cost calculations. Therefore, marginal cost only reflects the change in cost associated with variable factors of production.

The domain of the function of the bidirectional arrow is option A x ≥ 2.

The collection of all feasible input values (often x) for which a function is defined is known as its domain. Knowing a function's domain is crucial since it specifies the range of x values that can be used as inputs. An undefined result will be produced if we attempt to evaluate a function at a value of x outside of its domain. If a function, for instance, contains a square root in its expression, the domain must be limited to just non-negative values of x because it is impossible to get the square root of a negative number.

The graph has a bidirectional arrow that starts at x = 2 and goes forever to the right, hence the function is defined for any values of x greater than or equal to 2. Because there is no area of the graph to the left of x = 2, the function is not defined for any values of x less than 2.

Hence, the domain of the function of the bidirectional arrow is option A x ≥ 2.

Step-by-step explanation:

We can be 99.7% confident that the true proportion of individuals with schizophrenia in the population lies between 0.44 and 0.62.

In our schizophrenia model, the rough 99.7% certainty stretch can be determined utilizing the point gauge and standard blunder of the extent. With a point gauge of 0.53 and a standard blunder of 0.03, we can involve the equation for a certainty stretch, which is point gauge ± z* (standard mistake), where z* is the z-score related with the ideal certainty level.

For a 99.7% certainty stretch, the z-score is roughly 3. Consequently, the certainty span would be:

0.53 ± 3(0.03) = (0.44, 0.62)

This implies that we can be 99.7% certain that the genuine extent of people with schizophrenia in the populace lies somewhere in the range of 0.44 and 0.62.
