Answer:

cost per day = 2.99(c)+20
sam's lessons cost $30.47 per day

Step-by-step explanation:

2.99 (price of clay used per pound) * c (pounds of clay used) + 20 (cost of lesson)
2.99(c)+20
since sam uses 3.5 pounds of clay per lesson that's 2.99(3.5)+20, which is equal to 30.47

Answer:

  y = 8

Step-by-step explanation:

Given N(-3,-7), O(-4,-2), P(1, -7), and Q(-2, y), you want to find y such that NO ║ PQ.

When we plot the points, we see that point O is 1 unit left and 5 units up from point N. Point Q is on a line 3 units left of P, so it will need to be 3×5 = 15 units up from P in order for PQ to have the same slope as NO:

  y = -7 +15 = 8

The value of y is 8; the point Q is (-2, 8).

Based on the image, it can be inferred that the temperature is 40°C.

In the image you can see a thermometer that has different temperature measurements from -10°C to 60°C. In this thermometer the temperature is marked as indicated by the liquid inside the thermometer, that is, the black part inside.

According to the above, the temperature that this thermometer marks would be 40 ° C, this means that the temperature of that place is very warm. Additionally, we know that they are °C because at the bottom it is referenced with a symbol of the letter "°C". There are other types of degrees such as Fahrenheit or Kelvin.

Step-by-step explanation:

a) To find the percentage of pregnancies that should last between 26 and 275 days, we can calculate the area under the normal curve between these two values.

Using the standard normal distribution, we need to standardize the values by subtracting the mean and dividing by the standard deviation.

For 26 days:

Z = (26 - 262) / 18 = -12.222

For 275 days:

Z = (275 - 262) / 18 = 0.722

Now, we can find the corresponding probabilities using a standard normal table or a calculator.

The probability of a pregnancy lasting less than 26 days is P(Z < -12.222) which is essentially 0.

The probability of a pregnancy lasting less than 275 days is P(Z < 0.722) = 0.766.

To find the percentage between 26 and 275 days, we subtract the probability of less than 26 days from the probability of less than 275 days:

Percentage = 0.766 - 0 = 0.766 = 76.6%

Therefore, approximately 76.6% of pregnancies should last between 26 and 275 days.

b) To find the number of days for the longest 30% of all pregnancies, we need to find the corresponding Z-score for the upper 30% of the standard normal distribution.

Z(0.30) = 0.524 (approximately)

Now, we can reverse the standardization process to find the corresponding number of days:

X = Z * σ + μ

X = 0.524 * 18 + 262

X ≈ 271.43

Therefore, the longest 30% of all pregnancies should last at least approximately 271.43 days.

c) According to the Central Limit Theorem, the distribution of the sample mean will be approximately normal with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

Mean (μ) of the sample mean (y) = Mean of the population = 262 days

Standard deviation (σ) of the sample mean (y) = Standard deviation of the population / √n

σ(y) = 18 / √80 ≈ 2.015

Therefore, the mean of the distribution of the sample mean is 262 days and the standard deviation is approximately 2.015 days.

d) To find the probability that the mean duration of the patients' pregnancies will be less than 200 days, we can standardize the value using the sample mean and standard deviation:

Z = (200 - 262) / (18 / √80) ≈ -7.150

Using a standard normal table or a calculator, we find that P(Z < -7.150) is essentially 0.

Therefore, the probability of the mean duration of the patients' pregnancies being less than 200 days is very close to 0.

The probability that the next four trials will result in at least one subscription is =\(1 - (1-p)^{4}\)under the condition that streamers' decisions are independent.

Then the  probability of at least one success in four trials is evaluated by performing the formula

\(P(at least one success) = 1 - P(failure in one trial)^{n }\)

here n =  number of trials.

Assuming that streamers' decisions are independent,

we could use this formula to evaluate the probability of at least one subscription in four trials.

Then, if we consider that the probability of a subscription is p,

then the probability of no subscription is (1-p)

Hence, the probability of at least one subscription in four trials is

P(at least one subscription) = 1 - P(no subscription in four trials)

=\(1 - (1-p)^{4}\)

Answer:

The slope is \(\frac{3}{2}\)

Step-by-step explanation:

Hi there!

We are given the points (0, 4) and (6, 13)

We want to find the slope of the line containing these two points

Slope (m) is the steepness of the line. When calculating from two points, you use the equation \(\frac{y_2-y_1}{x_2-x_1}\), where \((x_1, y_1)\) and \((x_2, y_2)\) are points

Although we have what we need to find the slope, let's label the values of the points to avoid confusion and mistakes.

\(x_1=0\\y_1=4\\x_2=6\\y_2=13\)

Substitute these values into the equation

m=\(\frac{y_2-y_1}{x_2-x_1}\)

m=\(\frac{13-4}{6-0}\)

Subtract

m=\(\frac{9}{6}\)

Since Shay's sibling is 7 years younger than twice her age, Shay is therefore 29 years old.

Mathematicians use the unitary method, also referred to as the "single unit technique," to answer problems involving proportional relationships between two or more quantities. The unitary technique entails determining the value of a single unit or quantity and using that value to calculate the values of other quantities in relation to that unit or quantity. Problems requiring ratios, proportions, percentages, and other related ideas can be solved using this approach.

given

Shay's age will be denoted by the letter S, and her sister's age will be referred to as "Sister".

The first claim informs us of the following:

Sibling = 2S – 7

And based on the second assertion, we can infer that:

Sibling + S = 80

The result of putting the first equation into the second equation is:

S + (2S - 7) = 80

When we simplify this solution, we obtain:

3S - 7 = 80

7 added to both edges gives us:

3S = 87

When we multiply both parts by 3, we get:

S = 29

Since Shay's sibling is 7 years younger than twice her age, Shay is therefore 29 years old.

Feedback control uses information about the current state to make adjustments, while feedforward control proactively adjusts the input based on anticipated disturbances.

The main difference between feedback and feedforward control lies in the timing and direction of information flow. Feedback control uses information about the current state or output of a system to adjust the input and maintain stability or achieve a desired outcome. Feedforward control, on the other hand, anticipates disturbances or changes in the system and adjusts the input before they occur.

When feedback and feedforward control work together, they can enhance the overall performance of a system. Feedback control is effective at compensating for disturbances or errors that occur after they are detected. It continuously monitors the system's output and makes corrections accordingly. Feedforward control, on the other hand, proactively adjusts the input based on anticipated disturbances or changes. By doing so, it can minimize the impact of these disturbances and improve the system's response.

To better understand this, let's consider an example of a temperature control system for a room. In this system, the desired temperature is set at 70°F.

Feedback control constantly measures the current temperature in the room and compares it to the desired temperature. If the actual temperature deviates from the desired temperature, the feedback controller adjusts the heating or cooling system to bring the temperature back to the desired level.

Feedforward control, on the other hand, takes into account external factors that can affect the room temperature. For example, if it's a sunny day, the feedforward control system can anticipate that the room temperature may increase due to solar heat gain and proactively adjust the cooling system to counteract the temperature rise before it occurs.

When feedback and feedforward control work together in this temperature control system, the feedback control continuously monitors and adjusts the temperature based on the current state, while the feedforward control anticipates and compensates for external factors. This combined approach can lead to more precise temperature control and faster response to disturbances, resulting in a more comfortable environment.

In summary, feedback control uses information about the current state to make adjustments, while feedforward control proactively adjusts the input based on anticipated disturbances. When used together, they can enhance the performance of a system by compensating for both known and unknown factors, resulting in improved stability and response.

A triangle is a polygon with three sides (three edges and three vertices). There are different types of triangles which are equilateral triangles, right triangles, scalene triangles, obtuse triangles, acute triangles, and isosceles triangles.

An equilateral triangle is a triangle in which all its sides are equal and all its angles are equal to 60°.

From the triangle, AB = BC = AC = 9.5 cm

Since the triangle is enlarged 3.25 times, hence:

new length of BC = 9.25 cm × 3.25 = 30.875

New length of BC = 31 cm to nearest cm

The rate at which the distance between the two cars is changing at this instant in time is 3 feet per second.

Using this information, we can write expressions for the positions of the two cars as functions of time. The position of car A at time t is given by:

dA(t) = 18 + 8t

Similarly, the position of car B at time t is given by:

dB(t) = 26 + 11t

To find the distance between the two cars at time t, we can subtract these expressions:

d(t) = |dB(t) - dA(t)|

The absolute value signs are necessary because we don't know which car will be farther from the intersection at any given time. We only care about the distance between them, not the direction.

Now we need to find the rate at which d is changing at a specific instant in time. We can do this by taking the derivative of d with respect to time, t:

d'(t) = |dB'(t) - dA'(t)|

where dA'(t) and dB'(t) are the velocities of cars A and B at time t, respectively. We can find these velocities by taking the derivatives of the expressions we wrote for their positions:

dA'(t) = 8

dB'(t) = 11

Plugging these values into the derivative expression for d, we get:

d'(t) = |11 - 8|

Answer:

\(x = 94\)

Step-by-step explanation:

To find the value of \(x\), we have to first find the lengths of the sides of the squares and add them.

The formula for area of a square is as follows:

\({area = (length \space\ of \space\ side)^2}\)

This means the length of a side of a square can be found by:

\(\boxed {length \space\ of \space\ side = \sqrt{area}}\)

Now we can find the lengths of sides of each of the squares:
• Length of side of larger square = \(\sqrt{8100}\)

                                                       = 90

• Length of side of smaller square = \(\sqrt{16}\)

                                                          = 4

Next we can just add the lengths of the sides to get the value of \(x\) :

\(x = 90 + 4\)

⇒ \(x \bf = 94\)
