There are 720 possible three-digit numbers that can be formed from the digits 0, 1, 2, 3, 4, 5, and 6 if each digit can be used only once. Thus, 6 x 5 x 4 = 120, and 120 x 6 = 720.

There are 720 possible three-digit numbers that can be formed from the digits 0, 1, 2, 3, 4, 5, and 6 if each digit can be used only once. This is because you can have 6 different choices for the first digit, 5 choices for the second digit, and 4 choices for the third digit. This means that for each of the 6 choices for the first digit, you can have 5 choices for the second digit, and for each of those 5 choices, you can have 4 choices for the third digit. This results in 6 x 5 x 4 = 120 possible combinations for each of the 6 choices for the first digit. Since there are 6 choices for the first digit, 120 x 6 = 720 possible three-digit numbers in total.

I am not able to explain to you how I achieved these results, but at least you can try and see if you can solve the equation.

Answer:

No, (2,6) is not a solution to this system of equations.

Explanation:

Okay so lets restate the question:

Is (2, 6) a solution to this system of equations?

y = x + 4

y = 9x + 10

First, you find the x and y intercepts from the equations stated above.

y=x+4

x intercept(s): (-4,0)

y intercept(s): (0,4)

So for the first equation, (2,6) is not a solution.

Now, we find the x and y intercepts for the second equation.

y=9x+10

x intercept(s): (-10/9,0)

y intercept(s): (0,10)

So for the second equation, (2,6) is not a solution.

Both equations do not have (2,6) involved.

Weight of the John increased by 10.71 percent as he is weighing 140 pounds to 155 pounds.

As given in the question,

Original weight of John is equal to 140 pounds

John's changed weight is equal to 155 pounds

155 is greater than 140 pounds

Increase in John's weight.

Change in weight = Increased weight - actual weight

Percent of change in John's increased weight

= [ | change in weight| / Actual weight ] × 100

=  [(155 - 140 ) / 140] × 100

= (15 / 140)× 100

= 10.71%

Therefore, the percent of change in John's weight is increased by 10.71%.

The term for the value that occurs most often in a series of numbers is called the mode.

The mode is one of the three main measures of central tendency, along with the mean and the median. It is a useful descriptive statistic that can provide insights into the characteristics of a dataset.

To find the mode of a set of data, you first need to arrange the data in order, either in increasing or decreasing order. Then, you simply identify the most frequent data point, which is the mode. In some cases, there may be more than one mode if multiple data points occur with the same maximum frequency.

The mode is particularly useful when dealing with categorical or nominal data, where there are distinct categories or values that cannot be ordered in a meaningful way. For example, the mode can help identify the most popular color among a group of people or the most common type of car on a given street. It can also be used for continuous data, although it may be less useful in this case than the mean or median.

collecting like terms

y = 90 - 41 = 49°

Therefore,

y = 49°

The area of the composite figure is approximately 2447.43 square millimeters to the nearest hundredth.

To find the area of the composite figure, we need to divide it into simpler shapes and then find their areas separately. The composite figure is made up of a rectangle and two semicircles.

First, let's find the area of the rectangle. The length of the rectangle is 55 mm and the width is 32.5 mm, so the area of the rectangle is:

\($$A_{rect} = length \times width = 55 \text{ mm} \times 32.5 \text{ mm} = 1787.5 \text{ mm}^2$$\)

Next, let's find the area of each semicircle. The diameter of each semicircle is equal to the width of the rectangle, which is 32.5 mm. Therefore, the radius of each semicircle is:

\($$r =\) \(\frac{32.5 \text{ mm}}{2} = 16.25 \text{ mm}$$\)

The formula for the area of a semicircle is:

\($$A_{semicircle} = \frac{1}{2} \pi r^2$$\)

So, the area of each semicircle is:

\($$A_{semicircle} = \frac{1}{2} \pi (16.25 \text{ mm})^2 \approx 329.97 \text{ mm}^2$$\)

To find the total area of the composite figure, we add the area of the rectangle to the area of the two semicircles.

\($$A_{total} = A_{rect} + 2 \times A_{semicircle} \approx 2447.43 \text{ mm}^2$$\)

Therefore, the area of the composite figure is approximately 2447.43 square millimeters to the nearest hundredth.

To solve this problem, we first need to determine the probability of drawing a face card (not including aces) on the first draw. There are 12 face cards in a standard deck, and 32 non-face, non-ace cards. So the probability of drawing a face card on the first draw is 12/44.

Next, we need to determine the probability of drawing a face card on the second draw, given that we did not draw a face card on the first draw. There are now 11 face cards left in the deck, and 43 cards total (since we removed one card on the first draw). So the probability of drawing a face card on the second draw, given that we did not draw a face card on the first draw, is 11/43.

Finally, we need to determine the probability of drawing a face card on the third draw, given that we did not draw a face card on the first or second draw. There are now 10 face cards left in the deck, and 42 cards total (since we removed two cards on the first and second draws). So the probability of drawing a face card on the third draw, given that we did not draw a face card on the first or second draw, is 10/42.

To find the expected number of face cards (not including aces) that we will draw, we need to multiply the probabilities of each draw and sum the results. So:

Expected number of face cards = (12/44) * (11/43) * (10/42) * 3
Expected number of face cards = 0.038

Therefore, the expected number of face cards (not including aces) that you will draw when drawing three cards without replacement from a standard deck is approximately 0.038.

the minimum number of individual boots that must be picked to be sure of getting a matched pair is 2.

Since there are 9 pairs of boots in the pile, we can determine that each pair has two boots. If at most one boot is chosen from each pair, the maximum number of boots chosen would be 18.

To guarantee that a matched pair of boots is chosen, we must pick at least two boots from the pile, one from each boot of the same pair. Therefore, the minimum number of individual boots that must be picked to be sure of getting a matched pair is 2.

Number of pairs of boots in the pile = 9

Probability of Maya at home P(A) = 1/3

And probability of Jim at home P(B) = 1/4

The probability that Jim is home given that maya is home P(A∪B) = 1/2

We have to find the probability when they both are at home P(A ∩ B).

As we can see that the probability of both the events are independent

So, we can use

P(A ∪ B) = P(A) + P(B) – P(A ∩ B)

Therefore,

1/2 = 1/3 +1/4 – P(A ∩ B)

P(A ∩ B) = 7/12 – 1/2

P(A ∩ B) = 1/12

There are 4 incongruent primitive roots and 6 has order 12 and it is a primitive root.

There are 12 elements of the group     \(U_{13}\)   , namely all the positive integers less than 13, as these are relatively prime to 13. Now, if there are primitive roots, there are     \(\phi (\phi (n))\)    of them. So we must compute     \(\phi (12) = \phi (4\times 3) = \phi (4) \phi (3) = 2\times 2 = 4\)   . There are 4 incongruent primitive roots.

To find them, take the powers each element in turn:

1, 2, 4, 8, 3, 6, 12, 11, 9, 5, 10, 7, 1  (2 has order 12, it is a primitive root)

Of course, the higher powers of 2 cannot be.

Proceeding this way, we get next get that 6, 7, and 11 are also primitive roots.

For example, the powers of 6 give: 6, 10, 8, 9, 2, 12, 7, 3, 5, 4, 11, 1. We see 6 has order 12 and it is a primitive root. So 2, 6, 7, 11.
