The question presents a scenario where a fish is hovering at a certain depth below sea level, and then descends at a certain rate for a certain duration. So, Brenda is correct because her answer represents the new position of the fish in relation to sea level after the descent.

Brenda has provided an equation that represents the new position of the fish in relation to sea level after the descent. The equation is 2 times 8 + (negative 320) = 336. To determine if Brenda is correct, we need to understand the meaning of each term in the equation. The first term, 2 times 8, represents the distance the fish has descended, which is 16 feet (2 feet per second for 8 seconds).

The second term, negative 320, represents the initial depth of the fish below sea level. When we add these two terms together, we get the new depth of the fish below sea level, which is 336 feet.

Therefore, Brenda is correct because her answer represents the new position of the fish in relation to sea level after the descent. It is important to understand the meaning of each term in an equation to correctly interpret its result.

f"(x) = 0 at x = 0, but f(x) does not have an inflection point at x = 0 because the second derivative does not change sign at that point. In fact, f(x) is a convex function for all values of x, meaning it curves upwards and has no inflection points.

An inflection point is a point on a curve where the concavity changes, meaning that the second derivative of the function changes sign. Specifically, if f(x) is a twice-differentiable function, then a point c is an inflection point if f''(c) = 0 and the sign of f''(x) changes when x passes through c.

However, it is possible for a function to not have an inflection point at a point where f''(x) = 0. This can occur when the sign of f''(x) does not change as x passes through the point, meaning that the concavity does not change.

One simple example of such a function is f(x) = x^4. This function has a second derivative of f''(x) = 12x^2, which equals zero at x = 0. However, the sign of f''(x) is always positive, meaning that the concavity is always upward and does not change at x = 0. Therefore, f(x) does not have an inflection point at x = 0 despite f''(0) = 0.

In general, any even-degree polynomial will have a second derivative that equals zero at the origin, but the concavity will not change at the origin if the leading coefficient is positive. Other examples of functions that do not have inflection points at points where f''(x) = 0 include functions with constant concavity, such as f(x) = x^2 or f(x) = sin(x).

The z-score for which 99% of the distribution's area lies between -z and z is approximately ±2.575. This corresponds to option (-2.575, 2.575).

In statistics, the z-score represents the number of standard deviations an observation or data point is from the mean of a distribution. To find the z-score for which 99% of the distribution's area lies between -z and z, we need to determine the critical value z that leaves 0.5% of the area in each tail.

By looking up the z-score in the standard normal distribution table or using statistical software, we find that the z-score for a one-tailed 0.5% area is approximately ±2.575. Therefore, the z-score for which 99% of the distribution's area lies between -z and z is approximately ±2.575, as stated in option (-2.575, 2.575).

Answer:

39%

Step-by-step explanation:

It is given that 35 apartments have balconies in them.

While 55 apartments do not have balconies in them.

Total number of balconies is the sum of the apartments. i.e. 35 + 55

                                                                                             = 90 apartments

Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.

i.e.

\($=\frac{35}{90}$\)

= 0.38888888

Multiplying by 100, we get

= 0.388888 x 100

= 38.8888 %

We can use Bayes' theorem to find the conditional PDF of T given that the second arrival came before time t=1:

f(T|N(1) = 2) = f(N(1) = 2|T) * f(T) / f(N(1) = 2)

where f(N(1) = 2|T) is the probability that the second arrival occurs before time 1 given that the first arrival occurred at time T, f(T) is the PDF of the time of the first arrival.

f(N(1) = 2) is the probability that the second arrival occurs before time 1, which can be calculated using the Poisson distribution with rate lambda=2:

f(N(1) = 2) = (lambda*1)^2 * e^(-lambda*1) / 2! = 2e^(-2)

To find f(N(1) = 2|T), we note that this is equivalent to the probability that there is exactly one arrival in the interval (T, 1] (since the second arrival occurs before time 1).

This probability can be calculated using the Poisson distribution with rate lambda=2 and interval length 1-T:

f(N(1) = 2|T) = (lambda*(1-T))^1 * e^(-lambda*(1-T)) / 1! = 2e^(-2+2T)

To find f(T), we use the PDF of the exponential distribution with rate lambda=2, since the time of the first arrival in a Poisson process follows an exponential distribution with rate lambda:

f(T) = lambda * e^(-lambda*T) = 2e^(-2T)

Putting it all together, we have:

f(T|N(1) = 2) = f(N(1) = 2|T) * f(T) / f(N(1) = 2)

             = 2e^(-2+2T) * 2e^(-2T) / (2e^(-2))

             = e^(2-T), for 0 < T < 1

Therefore, the conditional PDF of T given that the second arrival came before time t=1 is f(T|N(1) = 2) = e^(2-T), for 0 < T < 1.

You're either asking to evaluate

1101² + 1101²

or, seeing as 1101 consists only of 0s and 1s, you're asking to compute a sum in base 2,

1101₂ + 1101₂

If you really mean 1101² + 1101², we have

1101² = (1100 + 1)²

… = 1100² + 2•1100•1 + 1²

… = 1,210,000 + 2200 + 1

… = 1,212,201

so that

1101² + 1101² = 2 • 1,212,201 = 2,424,402

I think the latter is the more likely scenario. In base 2, we have

0₂ + 0₂ = 0₂

1₂ + 0₂ = 0₂ + 1₂ = 1₂

1₂ + 1₂ = (2)₂ = (2 + 0)₂ = 10₂

So, when we add the digits of 1101₂ and 1101₂ in the same place value, we have

• in the "ones" place, 1₂ + 1₂ = 10₂

• in the "twos" place, 0₂ + 0₂ + 1₂ = 1₂, where we carry the leading 1 from the previous place sum

• in the "fours" place, 1₂ + 1₂ = 10₂

• in the "eights" place, 1₂ + 1₂ + 1₂ = 11₂, where we again carry the leading 1 from before

Then

1101₂ + 1101₂ = 11010₂

Answer:subtract to elimanate y

Step-by-step explanation:

The dot plot provided has a lower quartile of 10 and a median of 20. The student then sends 80 text messages on each of the next two days, and we need to determine the new median.

To find the new median after sending 80 text messages on each of the next two days, we need to consider the impact of these additional values on the data set. Since the dot plot does not provide the complete set of data, we cannot calculate the new exact median. However, we can make some observations.

Adding 80 to each data point would shift the entire data set upwards. This would cause the median to increase as well. The extent of the increase depends on the position of the new values within the existing data set. Without specific information about the distribution and placement of the data points, we cannot determine the exact new median.

Answer:I think it’s answer B

Step-by-step explanation:because if you measure figure 2 it will be about 451 and you need it to hold about 300 so it can’t be a or c and figure 3 holds about 321 while figure 1 holds about something so I think it’s B

Answer:

Angle F is 50° because their side lengths are different but the angle measurements did not change. All triangles add up to 180 degrees and a right angle is 90 and it gives you the other angle measurement. So you would do 40 plus 90 which would get you 130. To find the last angle you would do 180 minus 130 which is 50. Angle F is 50 degrees.

у = 12 - 4x

5x - Зу = -2

Solve the system algebraically.

Substitute the first equation into the second equation.

5x - 3( 12 - 4x) =-2

Distribute.

5x - 36 + 12x = -2

Combine like terms.

17x -36 = -2

Add 36 to each side

17x -36+26 = -2+36

17x = 24

Divide by 17

17x/17 = 34/17

x = 2

Answer:

x = 2

y = 4

Step-by-step explanation:

y = 12 - 4x  ⇒  ( 1 )

5x - 3y = -2  ⇒  ( 2 )

Let us find the value of x.

For that, take equation (2) and replace y with ( 12 - 4x ).

5x - 3y = -2

5x - 3 ( 12 - 4x ) = -2

5x - 36 + 12x = -2

Combine like terms.

17x - 36 = -2

Add 36 to both sides.

17x = -2 + 36

17x = 34

Divide both sides by 17.

x = 2

Let us find the value of y.

To find the value of y let us take equation ( 1 ) and replace x with 2.

y = 12 - 4 × 2

y = 12 - 8

y = 4

The ratio strength of the final product is 1:0.4.

One technique to indicate concentration is through ratio strength, which uses a ratio to characterize drug concentration. In this context, concentration is defined as the quantity of a solute that makes up one unit in the whole volume of a solution or combination. You should be an expert in ratio strength calculations as a pharmacy student. Ratio strength uses a ratio to describe the medication concentration. So, what it implies is, you have one unit of solute contained in the complete amount of preparation and so generally your ratio strength is expressed as one is to something. In the case of a weight-in-weight, volume-in-volume, or weight-in-volume situation, you would interpret a ratio of 1:2,000 differently.

Drug strength = 800mg

The probability of getting tails on the coin and an even number on the number cube is 1/4

Probabilities are used to determine the chances, likelihood, possibilities of an event or collection of events

The sample space of a coin is:

S = {H, T}

The sample space of a die is:

S = {1, 2, 3, 4, 5, 6}

The above means that:

A coin has 2 faces, one of which is the tail.

So, we have:

P(Tail) = 1/2

A number cube has 6 numbers, 3 or which are even.

So, we have

P(Even) = 3/6

The required probability is

P = P(Tail) * P(Even)

This gives

P = 1/2 * 3/6

Evaluate

P = 1/4

Evaluate the quotient

P = 0.25

Hence, the probability of getting tails on the coin and an even number on the number cube is 1/4 or 0.25
