By using empirical rule, approximately 34% of the students have grade point averages that are greater than 2.11.

The empirical rule, also known as the 68-95-99.7 rule, states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, approximately 95% falls within two standard deviations, and approximately 99.7% falls within three standard deviations.

We want to find the percentage of students with a GPA greater than 2.11. To do so, we need to calculate the number of standard deviations that separate 2.11 from the mean of 2.56:z = (2.11 - 2.56) / 0.45 = -1

Here, z represents the number of standard deviations away from the mean. A negative z-value indicates that the value of interest is below the mean.

Now that we have calculated the z-value, we can use the empirical rule to determine the percentage of students with a GPA greater than 2.11. Since the value of interest is below the mean, we need to calculate the percentage of students who fall within one standard deviation below the mean:

68% - 34% = 34%

Approximately 4.174 grams of ammonium phosphate ((NH₄)₃PO₄) will be produced by the reaction of 2.8 grams of phosphoric acid (H₃PO₄).

The mole idea is a useful way to indicate how much of a substance there is. Any measurement can be divided into two components: the magnitude in numbers and the units in which the magnitude is expressed.

To determine the mass of ammonium phosphate produced by the reaction of 2.8g of phosphoric acid (H₃PO₄), we need to consider the balanced chemical equation and the molar masses of the compounds involved.

The balanced chemical equation for the reaction is as follows:

H₃PO₄ + 3NH₃ -> (NH₄)₃PO₄

From the balanced equation, we can see that one mole of phosphoric acid (H₃PO₄) reacts with three moles of ammonia (NH₃) to produce one mole of ammonium phosphate ((NH₄)₃PO₄).

Step 1: Calculate the molar mass of H₃PO₄:

H = 1.00794 g/mol (1 hydrogen atom)

P = 30.97376 g/mol (1 phosphorus atom)

O = 15.999 g/mol (4 oxygen atoms)

Molar mass of H3PO4 = (1.00794 * 3) + 30.97376 + (15.999 * 4) = 97.995 g/mol

Step 2: Determine the number of moles of H₃PO₄:

Number of moles = mass / molar mass

Number of moles = 2.8g / 97.995 g/mol ≈ 0.028 moles

Step 3: Use stoichiometry to find the number of moles of ammonium phosphate:

From the balanced equation, we know that the ratio of moles of H₃PO₄ to moles of (NH₄)₃PO₄ is 1:1.

Therefore, the number of moles of (NH₄)₃PO₄ produced is also approximately 0.028 moles.

Step 4: Calculate the mass of (NH₄)₃PO₄:

Molar mass of (NH₄)₃PO₄:

N = 14.0067 g/mol (3 nitrogen atoms)

H = 1.00794 g/mol (12 hydrogen atoms)

P = 30.97376 g/mol (1 phosphorus atom)

O = 15.999 g/mol (4 oxygen atoms)

Molar mass of (NH₄)₃PO₄ = (14.0067 * 3) + (1.00794 * 12) + 30.97376 + (15.999 * 4) = 149.086 g/mol

Mass of (NH₄)₃PO₄ = number of moles * molar mass

Mass of (NH₄)₃PO₄ = 0.028 moles * 149.086 g/mol ≈ 4.174 g

Therefore, approximately 4.174 grams of ammonium phosphate ((NH₄)₃PO₄) will be produced by the reaction of 2.8 grams of phosphoric acid (H₃PO₄).

Step-by-step explanation:

The fraction of regions with speed limits less than 70 mph is 11/25.

To find the fraction of regions with speed limits less than 70 mph, we can subtract the fraction of regions with 70 mph speed limits from the fraction of regions with maximum speed limits up to and including 70 mph.

Fraction of regions with speed limits less than 70 mph = Fraction of regions with maximum speed limits up to and including 70 mph - Fraction of regions with 70 mph speed limits

= 39/50 - 17/50

To subtract fractions, we need a common denominator, which in this case is 50:

d. The price of the home in the first area is lower.

In Mathematics and Financial accounting, continuous compounding interest can be determined or calculated by using this mathematical equation (formula):

\(A(t) = P_{0}e^{rt}\)

Where:

Part a.

Based on an exponential growth rate of 3.8% in the first area, the cost of this home in t years can be written as follows;

\(A(t) = P_{0}e^{rt}\\\\C_1 = 250000e^{0.038t}\)

Part b.

Based on an exponential growth rate of 2.2% in the second area, the cost of this home in t years can be written as follows;

\(A(t) = P_{0}e^{rt}\\\\C_1 = 275000e^{0.022t}\)

Part c.

At a price of $320,000 for the home, the number of years to reach this price is given by:

\(C_1 = 250000e^{0.038t}\\\\320000 = 250000e^{0.038t}\\\\1.28= e^{0.038t}\)

ln(1.28) = 0.038t

Time, t = 0.24686007793/0.038

Answer:  C) as x → -∞, y → 3

                    as x→ ∞ , y → ∞

Step-by-step explanation:

see graph

Notice that as x approaches negative infinity (goes to the left), the y value approaches the asymptote of y = 3.

And as x approaches positive infinity (goes to the right), the y-value increases without bound so goes to infinity.

As x decreases without bound f(x) approaches but never reaches 3. As x increases without bound f(x) increases without bound. the option C is correct.

When the expression of function is such that it involves the input to be present as an exponent (power) of some constant, then such function is called exponential function.

Their usual form is specified below. They are written in several such equivalent forms.

From the graph, we can see that as x approaches negative infinity (goes to the left), the y value approaches the asymptote of y = 3.

As x approaches more negative the function will approach the horizontal asymptote,

so lim(f(x)) = 3 as x → -∞.

As x approaches more positive, so does the function,

so lim(f(x)) → +∞ as x → +∞.

As x decreases without bound f(x) approaches but never reaches 3. As x increases without bound f(x) increases without bound.

On average, there are approximately 1 customer in the bakery from 8 a.m. to 10 a.m.

To find the average number of customers in the bakery from 8 a.m. to 10 a.m., we need to divide the total time spent by all customers by the duration of the bakery's operating hours.

First, we need to convert all the times from minutes to hours. We can do this by dividing each time by 60:

10/60 = 0.1667

15/60 = 0.25

20/60 = 0.3333

11/60 = 0.1833

8/60 = 0.1333

12/60 = 0.2

25/60 = 0.4167

18/60 = 0.3

29/60 = 0.4833

32/60 = 0.5333

Next, we can sum all of these values to get the total time spent by customers:

0.1667 + 0.25 + 0.3333 + 0.1833 + 0.1333 + 0.2 + 0.4167 + 0.3 + 0.4833 + 0.5333 = 2.0766 hours

Since the bakery is open for 2 hours (from 8 a.m. to 10 a.m.), we can divide the total time spent by customers by the operating hours to get the average number of customers:

For various levels of output, businesses in a competitive market have the following production costs. Right now, the price on the market is $4. Total Cost Quantity 0 1 10 2 13 3 18 4 25 34. Therefore,

1. Each firm maximizes profit by supplying 2 units where MR = MC.

2. At $4 market price, market not in long-run equilibrium as ATC ($6.5) > price.

3. Market reaches long-run equilibrium at $6, the minimum point of ATC curve.

To determine the units each firm will supply to maximize profit and calculate the profit, we need to examine the cost and revenue associated with each quantity of output.

Quantity                    Total Cost

0                                       1

1                                       10

2                                      13

3                                      18

4                                     25

1. To find the quantity that maximizes profit for each firm, we need to compare the marginal cost (MC) and marginal revenue (MR) at each quantity level.

Quantity   Total Cost   MC       MR

0                  1                   -       -

1                  10                 9       4

2                  13                 3       4

3                  18                 5       4

4                  25                 7       4

To maximize profit, a firm will produce where MR equals MC. Looking at the table, we can see that at a quantity of 2, the MR and MC are equal. Therefore, each firm will supply 2 units to maximize profit.

2. To determine if the market is in long-run equilibrium at a market price of $4, we need to compare the market price with the average total cost (ATC) for each firm. If the market price is equal to or greater than the ATC, the market is in long-run equilibrium.

Let's calculate the ATC for each firm at a quantity of 2:

\(ATC = \frac{Total Cost}{Quantity}\)

\(ATC = \frac{13}{2}\)

ATC = 6.5

The ATC for each firm is $6.5, which is greater than the market price of $4. Therefore, the market is not in long-run equilibrium because firms are not covering their costs and would not continue to operate in the long run.

3. To determine the price at which the market will be in long-run equilibrium, we need to find the minimum point of the average total cost (ATC) curve. This point represents the price at which firms can cover their costs and earn a normal profit in the long run.

Looking at the table, we can observe that the minimum ATC occurs at a quantity of 3. Let's calculate the ATC at this quantity:

\(ATC = \frac{Total Cost}{Quantity}\)

\(ATC = \frac{18}{3} = 6\)

Therefore, the market will be in long-run equilibrium at a price of $6, which corresponds to the minimum point of the ATC curve.

The small boxes weigh 30 pounds, and the large boxes weigh 45 pounds.

Let the weight of the small box be x, and the weight of the large box be y. Then we have the following system of equations:x + y = 75 - Equation 1
We can see from the question that the truck is transporting 55 large boxes and 50 small boxes.
Therefore:55y + 50x = 3975 - Equation 2
We can use equation 1 to solve for x in terms of y, by subtracting y from both sides:x = 75 - y - Equation 3
We can substitute equation 3 into equation 2, to obtain:
55y + 50(75 - y) = 3975
This simplifies to:55y + 3750 - 50y = 3975
Simplifying further:5y + 3750 = 3975
Subtracting 3750 from both sides:5y = 225
Dividing both sides by 5:y = 45
Substituting y = 45 into equation 3, we can solve for x:x = 75 - 45x = 30

To solve this, we need to use the binomial probability distribution to find the probability of getting exactly six out of eight baseballs with straight stitching, given that the proportion of baseballs with straight stitching is 0.938.

The probability of getting exactly k successful outcomes out of n independent trials, where each trial has probability of success p, is given by the formula:

P(k) = (n choose k) * p^k * (1-p)^(n-k)

where "n choose k" is the binomial coefficient, which is the number of ways to choose k items from a set of n items.

In this case, the number of independent trials is 8, the probability of success is 0.938, and the number of successful outcomes is 6.

so, P(6) = (8 choose 6) * (0.938^6) * (1-0.938)^2

The equation x² + y² = 1/cos²(θ) represents a circle centered at the origin with a radius of 1/cos(θ).

In a two-dimensional or three-dimensional plane, the cartesian form is useful for representing a point, a line, or a plane. The x, y, and z axes are correspondingly used to express the cartesian form with regard to the three-dimensional cartesian system.

To find a Cartesian equation for the curve described by the polar equation r²cos(2θ) = 1, we can use the conversion formulas:

x = r cos(θ)

y = r sin(θ)

Substituting these into the given equation, we have:

(x² + y²)cos(2θ) = 1

Expanding the cosine term using the double-angle formula, cos(2θ) = cos²(θ) - sin²(θ), we get:

(x² + y²)(cos²(θ) - sin²(θ)) = 1

Simplifying further, we have:

x²cos²(θ) + y²cos²(θ) - x²sin²(θ) - y²sin²(θ) = 1

Using the identity cos²(θ) + sin²(θ) = 1, we can substitute it in the equation:

x² + y² - x²sin²(θ) - y²sin²(θ) = 1

Rearranging terms, we obtain:

x²(1 - sin²(θ)) + y²(1 - sin²(θ)) = 1

Using the identity 1 - sin²(θ) = cos²(θ), we can simplify further:

x²cos²(θ) + y²cos²(θ) = 1

Finally, dividing both sides by cos²(θ), we get:

x² + y² = 1/cos²(θ)

a) For 99.0:

Percent uncertainty = (1 / 99.0) * 100% = 1.01%

b) For 4.0√2:

Percent uncertainty = (1 / 4.0√2) * 100% = 17.8%

So, the percent uncertainties for the given numbers are approximately 1.01% and 17.8% respectively.

To determine which is a more meaningful way to express the accuracy of these two numbers, we need to consider the context and the desired level of precision.

Both significant figures and percent uncertainties have their merits and are used in different contexts. If the emphasis is on the precision of the measurement, significant figures are more appropriate.

The correct statement about their work is: Both Adler and Erika solved for k correctly because either the addition property of equality or the subtraction property of equality can be used to solve for k.

Adler started with the equation (13/8) = k(1/2) and subtracted 1/2 from both sides to get (13/8) - (1/2) = k(1/2) - (1/2). Then simplifying, Adler obtained (9/8) = k.

Erika started with the equation (13/8) = k(1/2) and multiplied both sides by -1/2 to get (13/8)(-1/2) = k(1/2)(-1/2). Simplifying, Erika obtained (9/8) = k.
