Answer:

After 13 days (Rounded) If you dont round it's \(\frac{90}{7}\) or 12\(\frac{6}{7}\)

Step-by-step explanation:

Perry: 180 - 6x = 8x

180 - 6x + 6x = 8x + 6x

180 = 14x

180/14 = 14x/14

90/7 = x

The number of students who registered for both robotics and app development is 70.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total members = 280

The number of members who registered for the robotics class.

= 75% of 280

= 3/4 x 280

= 3 x 70

= 210

The number of members who registered for the app development class

= 50% of 280

= 1/2 x 280

= 140

We see that,

210 + 140 = 350

But we have 280 members.

So,

The number of students who registered for both robotics and app development.

= 350 - 280

= 70

Thus,

The number of students who registered for both robotics and app development is 70.

Answer:

|8|

Step-by-step explanation:

Let the integer = x

x = - 2x - 24

x + 2x = - 24

3x = - 24

x = - 24/3

x = - 8

Hence, the integer is - 8

The number could be the positive of negative of 8

Hence, it is better expressed as |8|

To differentiate the function f(x) = qx + r/sx + t, where q, r, s, and t are constants, the derivative is given by f'(x) = q - (r/s) * (1/x^2).

To differentiate the given function, we need to apply the rules of differentiation. Let's break down the steps:

1. Differentiate qx with respect to x: Since q is a constant, the derivative of qx is simply q.

2. Differentiate r/sx with respect to x: We can rewrite r/sx as r * (s * x)^(-1). Applying the power rule of differentiation, the derivative of (s * x)^(-1) is (-1) * (s * x)^(-1 - 1) * s = -s/x^2.

3. Differentiate t with respect to x: Since t is a constant, the derivative of t with respect to x is 0.

4. Combining the derivatives obtained from the previous steps, we have f'(x) = q - (r/s) * (1/x^2).

Therefore, the derivative of the given function f(x) = qx + r/sx + t, where q, r, s, and t are constants, is f'(x) = q - (r/s) * (1/x^2).

The cutoff point for the number of minutes at which the customer should be contacted is 696 minutes

To calculate the upper fence for the monthly phone use data, we need to first find the quartiles.

Step 1: Arrange the data in order from smallest to largest

307, 335, 336, 341, 371, 375, 380, 395, 413, 424, 440, 465, 467, 489, 510, 512, 515, 521, 521

Step 2: Find the median

The median is the middle value of the data set. If the data set has an odd number of values, the median is the middle value. If the data set has an even number of values, the median is the average of the two middle values.

In this case, we have an even number of values, so we take the average of the two middle values

Median = (413 + 424)/2 = 418.5

Step 3: Find the first quartile (Q1)

The first quartile is the median of the lower half of the data set. To find Q1, we first find the median of the lower half:

Lower half: 307, 335, 336, 341, 371, 375, 380, 395, 413

Median of lower half = (371 + 375)/2 = 373

Step 4: Find the third quartile (Q3)

The third quartile is the median of the upper half of the data set. To find Q3, we first find the median of the upper half:

Upper half: 424, 440, 465, 467, 489, 510, 512, 515, 521, 521

Median of upper half = (489 + 510)/2 = 499.5

Step 5: Calculate the interquartile range (IQR)

The interquartile range is the difference between Q3 and Q1

IQR = Q3 - Q1 = 499.5 - 373 = 126.5

Step 6: Calculate the upper fence

The upper fence is defined as Q3 + 1.5 × IQR

Upper fence = Q3 + 1.5 × IQR = 499.5 + 1.5 × 126.5 = 695.75

Therefore, the cutoff point for the number of minutes at which the customer should be contacted is 696 minutes (rounded to the nearest minute).

Friend functions may directly modify or access the private data members. group of answer choices are true.

A friend function in C++ is a function that is not a member of a class but has access to its private and protected members. It is declared with the keyword "friend" inside the class. One of the advantages of using friend functions is that they can directly modify or access the private data members of a class, bypassing the normal access restrictions.

Friend functions are able to do this because they are granted special privileges by the class they are declared in. This means that they can access private data members and even modify them without using the usual public member functions of the class.

This feature can be useful in certain scenarios. For example, if we have a class that represents a complex number, we may want to provide a friend function to calculate the magnitude of the complex number directly using its private data members, instead of going through a getter function..

In conclusion, friend functions in C++ can indeed directly modify or access private data members. While this can be a powerful tool in certain cases, it should be used with caution to maintain the integrity of the class's encapsulation.

Answer:

x= 25

Step-by-step explanation:

2x + 3 + 4x + 6 + 12x + 18 = 477

FIRST combine like terms

take all "x"

2+4+12= 18x

take all whole numbers

3+6+18= 27

18x+27= 477

now solve for x

-27 on both sides

18x= 450

÷18 on both sides

x= 25

yoi have to add the variables so 2x +4x+12x=18x and concombine like terms so 3 +6+18=27 so you have to put tbat together 18x+27=477 then you have to get x alone so you have to subtract 27 in both sides 27-27=0 then 477-27=450 then you have to do the oppsite of multiply so you have to divide 18x/18x and 450/18x 18÷18 is 1 so you just have to put x and then divide 450÷18=25 so x=25.

The distance between the points (-7,1) and (-7,-5) on the coordinate plane is 6 units.

The distance formula is a useful tool in many areas of mathematics and science, such as geometry, physics, and engineering. It can be used to find the distance between two points in any number of dimensions, not just two dimensions as in the coordinate plane In addition, the distance formula can also be used to find the length of a line segment in the coordinate plane, which is just the distance between its endpoints. This can be useful in finding the shortest distance between two points, or in finding the length of a path that connects two points.

The distance formula is a mathematical equation used to find the distance between two points in the coordinate plane. It makes use of the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side (the hypotenuse).

In the coordinate plane, we can represent each point by its coordinates (x1, y1) and (x2, y2). The distance between the points is then given by the equation:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

For the points (-7,1) and (-7,-5), we can plug in the values into the equation:

distance = sqrt((-7-(-7))^2 + (-5-1)^2) = sqrt(0^2 + (-6)^2) = sqrt(36) = 6

So the distance between the points (-7,1) and (-7,-5) on the coordinate plane is 6 units.

The amount of Cashew nuts is 0.205

The amoun of Peanuts is 0.295

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

Amount of Cashew nuts = x

Amoun of Peanuts = y

Now,

We can make two equations.

x + y = 1/2 ____(1)

x = 1/2 - y  _____(20

Substituting (2) in (3)

6.25x + 2.10y = 1.90 _____(3)

6.25 (1/2 - y) + 2.10y = 1.90

3.125 - 6.25y + 2.10y = 1.90

3.125 - 4.15y = 1.90

3.125 - 1.90 = 4.15y

y = 1.225/4.15

y = 0.295

And,

x = 1/2 - y

x = 1/2 - 0.295

x = 0.205

Thus,

Amount of Cashew nuts = 0.205

Amoun of Peanuts = 0.295

In terms of classical conditioning, crinkling the bag of kitty treats serves as the conditioned stimulus. Classical conditioning involves the association of a neutral stimulus (conditioned stimulus) with a naturally occurring stimulus (unconditioned stimulus) to elicit a response.

Classical conditioning is a type of learning in which a neutral stimulus becomes associated with a naturally occurring stimulus to elicit a response. In this scenario, crinkling the bag of kitty treats is the neutral stimulus that becomes associated with the naturally occurring stimulus, which is the pleasure of eating treats for the cat.

The conditioned stimulus is the previously neutral stimulus that, through repeated pairing with the unconditioned stimulus (the naturally occurring stimulus), triggers a response. In this case, the crinkling sound of the bag becomes the conditioned stimulus because it is repeatedly paired with the unconditioned stimulus (the pleasure of eating treats), leading to the cat's response of coming running when it hears the bag being crinkled.

Over time, the cat learns to associate the sound of the crinkling bag with the reward of receiving treats, and the conditioned response of coming running is elicited by the conditioned stimulus alone, even without the presence of the unconditioned stimulus (the actual treats). This demonstrates the process of classical conditioning.

The main answer is that the difference between the number of strikes thrown before and after the training program for the Little League pitchers is as follows: -7, -7, 2, 4, 3, 2, 0, 2, 3, 3, 0, 2, -2, -4, -1, -1, 1, -3, -2, -1.

The table provides the number of strikes each player threw before and after the training program. To calculate the difference between the number of strikes thrown before and after, we subtract the "After" value from the "Before" value for each player.

For example, for the first player, the difference is 35 (After) - 28 (Before) = -7. Similarly, for the second player, the difference is 36 - 29 = -7. We repeat this calculation for each player and obtain the following differences: -7, -7, 2, 4, 3, 2, 0, 2, 3, 3, 0, 2, -2, -4, -1, -1, 1, -3, -2, -1.

These differences represent the change in the number of strikes thrown by each player after undergoing the training program. A negative difference indicates a decrease in the number of strikes, while a positive difference indicates an improvement. The range of differences is from -7 to 4, showing that the impact of the training program varied among the players.

It's important to note that the claim made in the advertisements suggested that players would be able to throw strikes on at least 60% of their pitches after the training. However, the difference values alone do not provide information about the success rate in terms of percentage. To determine if the training program was effective in meeting this claim, further analysis is needed, such as calculating the strike percentage for each player before and after the training and comparing them to the expected 60% threshold.
