Answer:

x=10

Step-by-step explanation:

On the basis of birthday problem or scenario, the number of people should be selected to guarantee that at least 4 were born on the same day, not considering the year is equals to the 1096.

The worst case scenario is one of the many possible cases where the desired outcome comes after every other probable outcome has already occurred. The number of people who ensure that at least 7 people have a birthday on a single day of a non-leap year (365 days) can be determined by ensuring that in the number of people selected in each trial, two people do not have a birthday on a day. the same day. There are 365 days in a year.

Assuming everyone was born on a different day, then you could have 365 people where no one was born on the same day, but those 366 people would have to be born on the same day as someone else in the group. So the minimum number of people in a group would have to be 366 to guarantee that at least 2 people were born on the same day. But we wanted to guarantee that at least 4 people were born on the same day.

So, assuming we had 3 × 365 people together, with every 3 of them being born on the same day. Then would have a total of 365× 3 = 1095 people, with no more than 3 people being born on the same day. Now as we select one more person, the number of people born on a day for one of the days in the year will increase to 4. Hence the number of people that should be selected to guarantee that at least 4 were born on the same day are 1095 +1 = 1096. Hence, required value is 1096.

Answer:

AZ = 12.80

Step-by-step explanation:

There are 2 triangles in the square XARS. Squares are always congruent, all sides are the same. Given that WT is 6, we can assume that RS is also 6 (because of congruency). RA is is the hypotenuse of the triangle ARS. To find AS, we can plug in the pythagorean theorem 6^2+x=^2=10^2. We end up getting square root of 64 which simplifies to 8. AS is now 8. We also know that ST is 6 since the square WRST has all congruent sides. 8+6=14 gives us line AT. TZ is 8 due to triangle XAR and the congruency theorem. Now we plug in pythagorean theorem to find AZ and we get 8^2+10^2=x^2. After simplifying the square root of 164, we see that AZ is equal to 12.80

The least amount is $100 and greatest amount is $140.

For given question,

We have been given the food budget is modeled by an equation,

1/2 |x - 120| = 10

where x is the amount spent on food.

We need to find the least and greatest amounts that the two friends could spend on food.

⇒ 1/2 |x - 120| = 10

⇒ |x - 120| = 20

We can observe that above equation contains absolute vale function.

⇒ x - 120 = ±20

⇒ x - 120 = -20         or          x - 120 = 20

⇒ x = 120 - 20          or          x = 120 + 20

⇒ x = 100               or         x = 140

1. When the population mean shifts to 7.8, the probability of detecting the change is approximately 0.0495 (or 4.95%).

2.  The probability of detecting the change is 0.0495 or 4.95%.

To solve this problem, we'll use the concept of control limits and the sampling distribution of the sample means.

When the population mean shifts to 7.8: First, let's calculate the standard deviation of the sampling distribution, also known as the standard error (SE). The formula for SE is given by SE = σ / sqrt(n), where σ is the standard deviation of the population (1.0 ounce) and n is the sample size (47).

SE = 1.0 / sqrt(47) ≈ 0.145

Next, we need to determine the z-score corresponding to the lower and upper tails of the sampling distribution that capture 5% each. Since the total probability in both tails is 10%, each tail will have a probability of 5%. We can find the z-scores using a standard normal distribution table or calculator.

The z-score corresponding to the lower tail of 5% is approximately -1.645.

The z-score corresponding to the upper tail of 5% is approximately 1.645.

Now, let's calculate the lower and upper control limits:

Lower Control Limit (LCL) = Population Mean - (z * SE)

Upper Control Limit (UCL) = Population Mean + (z * SE)

LCL = 7.8 - (-1.645 * 0.145) ≈ 8.026

UCL = 7.8 + (1.645 * 0.145) ≈ 9.574

To find the probability of detecting the change, we need to calculate the area under the sampling distribution curve that falls beyond the control limits. In this case, we're interested in the area above the upper control limit.

Since the distribution is assumed to be normal, we can use the standard normal distribution's cumulative distribution function (CDF) to calculate this probability.

Probability of detecting the change = 1 - CDF(z-score for UCL)

Using the z-score for the upper control limit (UCL), we can calculate the probability.

Probability of detecting the change ≈ 1 - CDF(1.645) ≈ 0.0495

Therefore, when the population mean shifts to 7.8, the probability of detecting the change is approximately 0.0495 (or 4.95%).

When the population mean shifts to 8.6: We'll follow the same steps as before.

SE = 1.0 / sqrt(47) ≈ 0.145

The z-score corresponding to the lower tail of 5% is still approximately -1.645.

The z-score corresponding to the upper tail of 5% is still approximately 1.645.

LCL = 8.6 - (-1.645 * 0.145) ≈ 8.926

UCL = 8.6 + (1.645 * 0.145) ≈ 10.274

Probability of detecting the change = 1 - CDF(z-score for UCL)

Probability of detecting the change ≈ 1 - CDF(1.645) ≈ 0.0495

Therefore, when the population mean shifts to 8.6, the probability of detecting the change is also approximately 0.0495 (or 4.95%).

In both cases, the probability of detecting the change is 0.0495 or 4.95%.

The 0-1 integer programming problem is solved using implicit enumeration to maximize the objective function 2x1 - x2 - x3, subject to three constraints.  The optimal solution to the 0-1 integer programming problem is x1 = 0, x2 = 1, and x3 = 1, with a maximum objective function value of 1.

The optimal solution is found by systematically evaluating all possible combinations of binary values for the decision variables x1, x2, and x3 and selecting the one that yields the highest objective function value.
To solve the 0-1 integer programming problem using implicit enumeration, we systematically evaluate all possible combinations of binary values for the decision variables x1, x2, and x3. In this case, there are only eight possible combinations since each variable can take on either 0 or 1. We calculate the objective function value for each combination and select the one that maximizes the objective function.
The first constraint, 2x1 + 3x2 - x3 ≤ 4, represents an upper limit on the sum of the decision variables weighted by their coefficients. We check each combination of x1, x2, and x3 to ensure that this constraint is satisfied.
The second constraint, 2x2 + x3 ≥ 2, represents a lower limit on the sum of the decision variables weighted by their coefficients. Again, we check each combination of x1, x2, and x3 to ensure that this constraint is met.
The third constraint, 3x1 + 3x2 + 3x3 ≥ 6, imposes a lower limit on the sum of the decision variables weighted by their coefficients. We evaluate each combination of x1, x2, and x3 to verify that this constraint is satisfied.
By evaluating all eight combinations and calculating the objective function value for each, we determine that the optimal solution occurs when x1 = 0, x2 = 1, and x3 = 1. This combination yields the maximum objective function value of 1. Therefore, the solution to the 0-1 integer programming problem, maximizing 2x1 - x2 - x3, subject to the given constraints, is achieved when x1 = 0, x2 = 1, and x3 = 1, resulting in an objective function value of 1.

Glow costs 16/27 dollars, which is equal to 59.3 cents per volume unit.

Let's start by assigning variables to the unknown prices and volumes of the toothpastes. Let x be the price per unit volume of Fresh, y be the price per unit volume of Glow, and z be the price per unit volume of Bright. Let v1 be the volume of Fresh, v2 be the volume of Glow, and v3 be the volume of Bright. From the information given in the problem, we can set up the following equations:

z = 1.6y (a tube of Bright is 60% more expensive than a tube of Fresh)

v3 = 0.75v2 (a tube of Bright has 25% less volume than Glow)

y = 0.75z (a tube of Glow is 25% less expensive than a tube of Bright)

v2 = v1 + 100/3 (a tube of Glow has 100/3 more volume than Fresh)

We can substitute the first equation into the second equation to eliminate z:

v3 = 0.75v2

(substitute v2 = 0.75z and v1 = 1)

0.75v2 = 0.75(0.75z + 100/3)

0.75v2 = 0.5625z + 25

(substitute z = 1.6y and v2 = v1 + 100/3)

0.75(v1 + 100/3) = 0.5625(1.6y) + 25

0.75v1 + 25/3 = 0.9y + 25

0.75v1 = 0.9y + 50/3

We can substitute the third equation into the fourth equation to eliminate y:

v2 = v1 + 100/3

(substitute y = 0.75z)

0.75z = 0.75(0.75y) + 100/3

z = y + 16/9

(substitute z = 1.6y)

1.6y = y + 16/9

y = 16/27

Therefore, the price per unit volume of Glow is 16/27 dollars, or 59.3 cents per unit of volume.

Answer:

x = 20

Step-by-step explanation:

\(\frac{10}{x}\) = \(\frac{x}{40}\)

We cross-multiply and get

400 = \(x^{2}\)

\(\sqrt{400}\) = \(\sqrt{x^{2} }\)

x = 20

So, the answer is x = 20

f(x) ≠ g(x) for all x in the real numbers.

To determine if f(x) = g(x), we need to check if they are equal for all x in the real numbers.

f(x) = 2x

g(x) = (2x^3 + 2x) / (x^3 + 1)

We can simplify g(x) by factoring out 2x from the numerator:

g(x) = 2x (x^2 + 1) / (x^3 + 1)

Now, we can see that f(x) and g(x) are not equal for all values of x in the real numbers, since g(x) has an additional factor of (x^2 + 1) in the denominator compared to f(x). Therefore, f(x) ≠ g(x) for all x in the real numbers.

In other words, the functions f and g are not the same function, as they have different formulas and produce different outputs for some (or all) values of x.
