a. The probability that a sample of 10 people has a mean glucose level less than 84.5 is 47.48%. b. The probability that a sample of 100 people has a mean glucose level less than 84.5 is or 42.07%.

To calculate the probabilities in this scenario, we will use the properties of the normal distribution and the central limit theorem. The central limit theorem states that for a large sample size, the distribution of the sample mean approaches a normal distribution, even if the underlying population distribution is not normal. In both cases, we can use the z-score formula to find the probabilities.

a. For a sample of 10 people:

The mean of the sample mean is equal to the population mean, which is 85. The standard deviation of the sample mean (also known as the standard error) is given by the population standard deviation divided by the square root of the sample size: 25/sqrt(10) ≈ 7.9057.

To find the probability that the sample mean is less than 84.5, we calculate the z-score:

z = (84.5 - 85) / 7.9057 ≈ -0.0634

Using a standard normal distribution table or a calculator, we find that the probability corresponding to a z-score of -0.0634 is approximately 0.4748, or 47.48%.

b. For a sample of 100 people:

Similarly, the mean of the sample mean is still 85, but the standard deviation of the sample mean (standard error) is now 25/sqrt(100) = 2.5.

To find the probability that the sample mean is less than 84.5, we calculate the z-score:

z = (84.5 - 85) / 2.5 = -0.2

Using the standard normal distribution table or a calculator, we find that the probability corresponding to a z-score of -0.2 is approximately 0.4207, or 42.07%.

Therefore:

a. The probability that a sample of 10 people has a mean glucose level less than 84.5 is approximately 0.4748, or 47.48%.

b. The probability that a sample of 100 people has a mean glucose level less than 84.5 is approximately 0.4207, or 42.07%.

Answer:

In mathematics, a function is a binary relation over two sets that associates to every element of the first set exactly one element of the second set. Typical examples are functions from integers to integers or from the real numbers to real numbers.

Step-by-step explanation:

The correct option is A) No, because the center of a distribution and the spread are not related

The standard deviation is a measure of the spread or dispersion of a set of data. It is not directly related to the mean or average of the data.

The standard deviation is calculated based on the deviations of each data point from the mean, taking into account how many data points there are.

The mean does not affect the calculation of the standard deviation, as the formula for standard deviation is based solely on the data itself and not on any summary statistics like the mean.

The value of the standard deviation can remain the same even if the mean changes, and conversely, the mean can change without affecting the standard deviation.

Thus, option A) No, because the center of a distribution and the spread are not related is correct.

A geometric series is the collection of an unlimited number of terms with a fixed ratio between them. The missing value in the table below is 343. The correct option is A.

A geometric series is the collection of an unlimited number of terms with a fixed ratio between them.

The given table if closely observed forms a geometric progression, this is because the value of the dependent variable, y is increasing by a common ratio. The common ratio in the table is,

Common ratio = y₂/y₁ = 1/(1/7) = 7

Now, for any geometric progression, the value of the nth term is given as,

Tₙ = a₁ (r)⁽ⁿ⁻¹⁾

where a₁ is the first term of the geometric progression and r is the common ratio. Therefore, the nth term of the series is,

T = a₁ (r)⁽ⁿ⁻¹⁾

Tₙ = (1/7) (7)⁽ⁿ⁻¹⁾

y = (1/7)(7)⁽ˣ⁻¹⁾

Now, the value of the y when the value of x is 5 is,

y = (1/7)(7)⁽ˣ⁻¹⁾

y = (1/7)(7)⁽⁵⁻¹⁾

y = (1/7)(7)⁴

y = (1/7) × 2401

y = 343

There can be a total of 6300 different snacks created using 2 types of dried fruits, 1 granola bar, and 2 packs of nuts.

We have,

To determine the number of snacks that can be created with the given options, we need to calculate the combinations of the different components.

Number of options for granola bars: 5

Number of options for dried fruits: 8 (selecting 2)

Number of options for packs of nuts: 10 (selecting 2)

To calculate the total number of snacks, we multiply the number of options for each component together:

Total number of snacks = Number of options for granola bars × Number of options for dried fruits × Number of options for packs of nuts

Total number of snacks = 5 × C(8, 2) × C(10, 2)

Here, C(n, r) represents the combination of choosing r items from a set of n items.

Evaluating the combinations:

C(8, 2) = 8! / (2! x (8-2)!) = 8! / (2! x 6!) = (8 x 7) / (2 x 1) = 28

C(10, 2) = 10! / (2! x (10-2)!) = 10! / (2! x 8!) = (10 x 9) / (2 x 1) = 45

Substituting these values back into the equation:

Total number of snacks = 5 × 28 × 45 = 6300

Therefore,

There can be a total of 6300 different snacks created using 2 types of dried fruits, 1 granola bar, and 2 packs of nuts.

To find the values of a and b, we can use the given points p(3,0) and q(-3,4) on the line ax+by=6. Substituting the coordinates of p into the equation, we get 3a + 0b = 6, which simplifies to 3a = 6.

Dividing both sides by 3 gives a = 2. Substituting the coordinates of q, we get -3a + 4b = 6. Substituting the value of a we found, -6 + 4b = 6, which simplifies to 4b = 12. Dividing both sides by 4 gives b = 3. Therefore, the values of a and b are 2 and 3, respectively.

Given two points on the line, we substitute their coordinates into the equation ax + by = 6. This gives us two equations: 3a + 0b = 6 and -3a + 4b = 6. Simplifying these equations, we find a = 2 and b = 3. Therefore, the line equation is 2x + 3y = 6.

The unit vector that has the same direction as -5i + 9j is (-5/106)i + (9/106)j.

To find a unit vector with the same direction as a given vector, we need to:

To find a unit vector with the same direction as -5i + 9j, we need to divide this vector by its magnitude:

For the vector -5i + 9j, the magnitude is:

\(| -5i + 9j | = sqrt((-5)^2 + 9^2) = sqrt(106)\)

To find a unit vector in the same direction, we divide the vector by its magnitude:

\((-5i + 9j) / | -5i + 9j | = (-5/106)i + (9/106)j\)

First, let's calculate the Profit functions which is P(x)=R(x)-C(x)

Let's continue simplifying the function

The profit function is a polynomial function, so the domain is all the real numbers which means x can be any real number

Domain=(-∞,∞)

Calculating x=-10 doesn't make sense because x in all the functions is the number of items, and doesn't make sense to have -10 items, so x shouldn't be negative numbers.

And Calculating x=1000 doesn't make sense either because the problem says "The maximum capacity of the company is 110 items" so if we have x=1000 we are exceeding the limit of items that the company can handle.

Now let's calculate the profit when producing 40 and 50 items (we just need to evaluate those values in the function):

The profit when the company produces 50 items is 500 and the profit when the company produces 40 items is 550.

The company should choose to produce 40 items because is a higher profit in contrast to making 50 items.

According to the function, when we replace the values in X we can see that the term (X^2) grows more than the term X and as you can see the term X^2 is negative which decreases the final result of the profit. Another way to see this is by drawing the function

As you can see the function is a parable and when the number of items "X" is very high the function tends to decrease. The function starts to grow in profit until 40 items (when you find the maximum value of profit) and then the profit function decreases.

The closest option to the reorder point is 71.40 pounds.

To determine the reorder point, we need to find the demand during the lead time and the safety stock.

First, let's calculate the demand during the lead time. The mean daily rate is 15 pounds, and it takes 4 days for the order to arrive. So, the mean demand during the lead time is 15 pounds/day * 4 days = 60 pounds.

Next, let's calculate the safety stock. The pizza shop wants to limit the probability of a stockout to 7 percent. We can find this value using the z-score table.

Looking up the z-score corresponding to a 7 percent probability, we find that it is approximately 1.89.

The standard deviation is given as 6 pounds.

So, the safety stock is calculated as 1.89 * 6 pounds = 11.34 pounds.

Finally, the reorder point is the sum of the mean demand during the lead time and the safety stock.

Reorder point = 60 pounds + 11.34 pounds = 71.34 pounds.

Therefore, the closest option to the reorder point is 71.40 pounds.

The probability of drawing one blue cube and one yellow cube from the bag is 2/25 or 8%.

Determine the total number of cubes in the bag.

There are a total of 2 yellow cubes + 1 red cube + 1 blue cube + 1 green cube = 5 cubes in the bag.

Determine the number of ways to draw one blue cube and one yellow cube.

To draw one blue cube and one yellow cube, we need to consider the number of ways to choose one blue cube out of the two available blue cubes and one yellow cube out of the two available yellow cubes. The number of ways can be calculated using the multiplication principle.

Number of ways to choose one blue cube = 2

Number of ways to choose one yellow cube = 2

Using the multiplication principle, the total number of ways to draw one blue cube and one yellow cube = 2 x 2 = 4.

Determine the total number of possible outcomes.

The total number of possible outcomes is the total number of ways to draw two cubes from the bag, with replacement. Since we put the cube back into the bag after each draw, the number of possible outcomes remains the same as the total number of cubes in the bag.

Total number of possible outcomes = 5

Calculate the probability.

The probability of drawing one blue cube and one yellow cube is given by the number of favorable outcomes (4) divided by the total number of possible outcomes (5).

Probability = Number of favorable outcomes / Total number of possible outcomes = 4 / 5 = 2/25 or 8%.
