The observed and expected frequencies for the green candies is C. Observed: 93 Expected: 103.6

The number of participants or observations included in a study is referred to as the sample size. Usually, n is used to represent this number. Research results are directly impacted by sample size calculations. Very small sample sizes compromise a study's internal and external validity. Small differences frequently become statistically significant differences in very large samples.

Sample size = 518

The number of green candies observed/counted is = 93

That's an approximated value for 18% of the 518 candies

  y +3 = -x -6

  See the attachment for a graph

Step-by-step explanation:

You want the point-slope equation and graph of the line through point (-6, -3) with slope -1.

The point-slope equation of a line through point (h, k) with slope m is ...

  y -k = m(x -h)

You have (h, k) = (-6, -3) and m = -1, so the equation is ...

  y -(-3) = (-1)(x -(-6))

  y +3 = -x -6 . . . . . point slope equation

The slope is the ratio of "rise" to "run" for the line. A slope of -1 means the "rise" is -1 for each 1 unit to the right. That is, (-6+1, -3-1) = (-5, -4) will be another point on the line, in addition to the one given.

a) The monthly charge if 110 kWh of electricity is consumed in a month is $38.80.

b) limit x --> 100 C(x) = $38.80 and limit x--> 500 C(x) = $188.80.

c) Yes, C is continuous at x = 100.

d) Yes, C is continuous at x = 500.

(a) If 110 kWh of electricity is consumed in a month, then we use the second formula: C(110) = 38.80 + 0.15(110-100) = $40.30.

(b) To find the limit as x approaches 100, we can simply substitute 100 into the first formula:

lim x --> 100 C(x) = C(100) = 20 + 0.188(100) = $38.80.

To find the limit as x approaches 500,

we can use the third formula: lim x --> 500 C(x) = 98.80 + 0.30(500-500) = $98.80.

(c) Since lim x --> 100 C(x) = C(100), C is continuous at x = 100.

(d) Since lim x --> 500 C(x) = C(500), C is continuous at x = 500.

The provided questions cover various aspects of a 2-period production economy, including the household's problem, firm's problem, market clearing conditions, Social Planner's Problem, competitive equilibrium, and welfare theorems.

(a) The Household's problem is to maximize its utility over two periods subject to its budget constraint. The household's problem can be formulated as follows:

Max U(Co, C1) = log(Co) + ß log(C1)

subject to the budget constraint:

Co + (1+r)C1 ≤ (1+r)Ko + W0 + W1,

where Co and C1 are consumption in period 0 and 1 respectively, ß is the discount factor, r is the interest rate, Ko is the initial capital endowment, W0 and W1 are the wages in periods 0 and 1 respectively.

(b) The Firm's problem is to maximize its profit by choosing the optimal combination of capital and labor. The firm's problem can be formulated as follows:

Maximize F(K, L) - RK - WL,

where F(K, L) is the production function, K is capital, L is labor, R is the rental rate of capital, and W is the wage rate.

(c) The market clearing conditions are:

Capital market clearing: K1 = (1 - δ)K0 + S - C0, where δ is the depreciation rate, S is savings, and C0 is consumption in period 0.

Labor market clearing: L = L0 + L1, where L0 and L1 are labor supplies in periods 0 and 1 respectively.

(d) The Social Planner's Problem is to maximize social welfare, which is the sum of the household's utility and the firm's profit. The Social Planner's Problem can be formulated as follows:

Maximize U(C0, C1) + F(K, L) - RK - WL,

subject to the production function F(K, L) and the market clearing conditions.

(e) A Competitive Equilibrium is a situation where all markets clear and agents (household and firm) make optimal decisions based on prices and market conditions. It is characterized by the following conditions:

Household's problem is solved optimally.

Firm's problem is solved optimally.

Market clearing conditions hold.

(f) To solve the Social Planner's Problem, we need to set up the Lagrangian and solve for the optimal values of consumption, capital, and labor. The Lagrangian can be written as:

L = U(C0, C1) + F(K, L) - RK - WL + λ1[(1+r)K0 + W0 + W1 - Co - (1+r)C1] + λ2[K1 - (1 - δ)K0 + S - C0] + λ3[L - L0 - L1],

where λ1, λ2, and λ3 are the Lagrange multipliers.

(g) To solve the Competitive Equilibrium, we need to determine the prices of capital (R) and labor (W) that clear the markets. This can be done by equating the demand and supply of capital and labor, and solving the resulting equations.

(h) The First Welfare Theorem states that under certain conditions, a competitive equilibrium is Pareto efficient. It implies that a competitive equilibrium is a socially optimal allocation of resources. To verify the theorem, we need to demonstrate that the competitive equilibrium allocation is Pareto efficient.

(i) The Second Welfare Theorem states that any Pareto efficient allocation can be achieved as a competitive equilibrium with appropriate redistribution of initial endowments.

To verify the theorem, we need to show that given an initial Pareto efficient allocation, we can find prices and redistribution of endowments that lead to a competitive equilibrium that achieves the same allocation.

Answer:

3.89

Step-by-step explanation:

To find the price per quart of the window cleaner, we need to first determine how many quarts the 3-gallon container contains. We can do this by converting the number of gallons to quarts using the conversion factor that 1 gallon is equal to 4 quarts.

3 gallons * 4 quarts/gallon = 12 quarts

Next, we need to divide the total cost of the window cleaner, $46.68, by the number of quarts to find the price per quart.

Price per quart = $46.68 / 12 quarts = $3.89/quart

Therefore, the price per quart of the window cleaner is $3.89.

If a sample of 8 scores has a mean of 10 and after removing one score, the mean of the remaining scores is 11, the score that was removed is 7.

The mean of the original sample is 10. This means that the sum of the scores in the sample is 8 multiplied by 10, which equals 80. After one score is removed, the mean of the remaining scores is 11. Since there are now 7 scores remaining in the sample, the sum of those scores is 7 multiplied by 11, which equals 77.

To find the score that was removed, we need to calculate the difference between the sum of the original sample and the sum of the remaining scores. The difference is 80 minus 77, which equals 3. Therefore, the score that was removed from the sample is 3.

a. The domain is (-∞, +∞) in interval notation.

b. As x approaches positive infinity, p(x) approaches positive infinity.

As x approaches negative infinity, p(x) approaches negative infinity.

c.  the y-intercept has the coordinates (0, 0).

d. The zeros of the function are: x = 0 , x = -5, x = -1

e.  The x-intercepts are -5 and -1.

a. The domain of a polynomial function is all real numbers, so in interval notation, the domain of p(x) is (-∞, ∞).

b. To determine the end behavior of the function, we examine the highest power of x in the polynomial. In this case, the highest power is 6, so the end behavior of the function is as follows:

- As x approaches negative infinity (-∞), p(x) approaches positive infinity (+∞).

- As x approaches positive infinity (+∞), p(x) approaches positive infinity (+∞).

c. The y-intercept is the value of the function when x = 0. Substituting x = 0 into p(x), we get:

\(p(0) = -2(0)(3(0)+15)^2(0^2+2(0)+1)p(0) = -2(0)(15)^2(1)\)

p(0) = 0

Therefore, the coordinates of the y-intercept are (0, 0).

d. To find the zeros of the function, we set p(x) equal to zero and solve for x. Let's factor the polynomial to find the zeros:

p(x) = \(-2x(3x + 15)^2(x^2 + 2x + 1)\)

Setting p(x) = 0, we have:

\(-2x(3x + 15)^2(x^2 + 2x + 1)\) = 0

The zeros are obtained when any of the factors equal zero. So the zeros and their multiplicities are as follows:

Zero with multiplicity 1: x = 0

Zero with multiplicity 2: 3x + 15 = 0 ⟹ x = -5

Zero with multiplicity 2: x² + 2x + 1 = 0 ⟹ (x + 1)² = 0 ⟹ x = -1

e. The x-intercepts are the points where the graph of the function intersects the x-axis. We already found the zeros of the function in the previous step, and those are the x-intercepts. Therefore, the x-intercepts are -5 and -1.

f. To graph p(x), we can start by plotting the y-intercept (0, 0) and the x-intercepts (-5, 0) and (-1, 0). We know the end behavior is a positive curve in both directions. Based on the multiplicity of the zeros, we can determine how the graph behaves at each x-intercept:

- At x = -5, the zero has multiplicity 2, so the graph touches but does not cross the x-axis.

- At x = -1, the zero has multiplicity 2, so the graph touches but does not cross the x-axis.

The shape of the graph between the x-intercepts can be determined by the leading term of the polynomial, which is -2x⁶. It indicates that the graph is a downward-facing curve.

Putting all this information together, the graph of p(x) would look something like this:

There are actually three null hypotheses associated with a two-way ANOVA. These null hypotheses are related to the main effects of each of the two factors, as well as the interaction effect between the two factors. Each of these null hypotheses must be tested separately in order to fully understand the results of the ANOVA.

In a two-way ANOVA, there are three null hypotheses associated with the analysis. These hypotheses are used to examine the effects of two independent factors on a dependent variable. The three null hypotheses are as follows: 1. The first null hypothesis (H01) states that there is no significant effect of the first independent factor on the dependent variable, meaning that all the levels of the first factor have the same population mean. 2. The second null hypothesis (H02) states that there is no significant effect of the second independent factor on the dependent variable, meaning that all the levels of the second factor have the same population mean. 3.

The correct answer is a. single-factor, independent groups design. In this design, there is one independent variable with two or more levels, and participants are randomly assigned to these levels, making the groups independent.

A t test for independent groups is specifically used to compare the means of two independent groups in an experimental design, where participants are randomly assigned to either a control or treatment group. This design is also known as a between-subjects design, as participants are only exposed to one level of the independent variable (the treatment or control condition). The other options listed - matched groups design and nonequivalent groups design - both involve some form of matching or pairing of participants, which would require a different type of statistical test (e.g. a paired t test or ANOVA).

The coefficient matrix in this case is

A = [[0, -2, -2], [-2, 0, -2], [-2, -2, 0]].

By solving the characteristic equation det(A - λI) = 0, where λ is the eigenvalue and I is the identity matrix, we can find the eigenvalues. In this case, the eigenvalues are λ₁ = -4, λ₂ = 0, and λ₃ = 4.

Substituting the values of Y and P, we have:

[ x₁ ] [ 1 -1 -1 ] [ y₁ ]

[ x₂ ] = [ 1 1 0 ] * [ y₂ ]

[ x₃ ] [ 1 0 1 ] [ y₃ ]

Multiplying the matrices, we get:

[ x₁ ] [ y₁ - y₂ - y₃ ]

[ x₂ ] = [ y₁ + y₂ ]

[ x₃ ] [ y₁ + y₃ ]

Therefore, the solutions for the original system of differential equations are:

x₁(t) = y₁(t) - y₂(t) - y₃(t)

x₂(t) = y₁(t) + y₂(t)

x₃(t) = y₁(t) + y₃(t)

Substituting the solutions for y₁, y₂, and y₃ derived earlier, we can express the solutions for x₁, x₂, and x₃ in terms of the constants of integration c₁, c₂, and c₃:

x₁(t) = c₁e^(-4t) - c₂e^(2t) - c₃e^(2t)

x₂(t) = c₁e^(-4t) + c₂e^(2t)

x₃(t) = c₁e^(-4t) + c₃e^(2t)

The surface area of the solid pyramids are as follows;

First figure; 436 square units

Second figure; 319 square units

Third figure; 673 square units

A pyramid is a shape that consists of a polygon base and side faces that are triangular.

First figure

The figure is a pentagonal pyramid of height 8 units and side length of 10 units

The apothem, a, can be obtained from the formula;

\(a = \dfrac{s}{2\cdot tan \left(\dfrac{180}{n} \right)}\)

s = 10

n = 5

\(a = \dfrac{10}{2\cdot tan \left(\dfrac{180}{5} \right)} \approx 6.88\)

Slant height ≈ √(8² + 6.88²) ≈ 10.55

Area of the 5 triangles = 5 × (1/2) × 10 × 10.55 ≈ 263.75

Area of pentagonal base ≈ (1/2) × 6.88 × 5 × 10 = 172
Area of the figure ≈ 263.75 + 172 ≈ 436

Second figure;

Square pyramid

n = 4

When s = 8, we get;

\(a = \dfrac{12}{2\cdot tan \left(\dfrac{180}{4} \right)} =6\)

Slant height of the 8 units long side = √(6² + 10²) ≈ 11.66

Area of two of the four triangle surfaces = 2×(1/2)×8 ×11.66≈ 93.28

When s = 12 we get;

\(a = \dfrac{8}{2\cdot tan \left(\dfrac{180}{4} \right)} =4\)

Slant height of the 12 units long side = √(4² + 10²) ≈ 10.77

Area of two of the four triangle surfaces = 2×(1/2)×12 × 10.77 ≈ 129.24

Area of the rectangular base = 12 × 8 = 96

Area of the figure = 93.28 + 129.24 + 96 ≈ 319

Third figure

Octagonal pyramid

n = 8

s = 8

\(a = \dfrac{8}{2\cdot tan \left(\dfrac{180}{8} \right)}\approx 9.66\)

Slant height = √(9.66² + 6²) ≈ 11.37

Area of the 8 triangles = 8 × (1/2) × 8 × 11.37 ≈ 363.84

Area of the octagonal base = 2×(1 + √2)×s²

Therefore;

2×(1 + √2)×8² ≈ 309.02

a) The probability that all twenty customers purchase more than 10 items so the quick-check lane will not be needed is 0.00390625,
b) The probability that at least one customer purchases 10 items or less, so the quick-check lane will be needed is 0.99609375.

To calculate the probability of all twenty customers purchasing more than 10 items, we first find the probability of one customer purchasing more than 10 items. From store records, we know that the probability of a randomly chosen customer purchasing more than 10 items is 0.75. Thus, the probability of one customer purchasing more than 10 items is 0.75.

Next, we need to calculate the probability of all twenty customers purchasing more than 10 items. To do this, we use the formula for probability of independent events: P(A and B) = P(A) * P(B). In this case, we use the formula P(A and B and C and ...) = P(A) * P(B) * P(C) * .... Therefore, the probability that all twenty customers purchase more than 10 items is 0.7520 = 0.00390625.

To calculate the probability that at least one customer purchases 10 items or less, we use the formula for the probability of an event not occurring: P(not A) = 1 - P(A). In this case, the probability that at least one customer purchases 10 items or less is 1 - 0.7520 = 0.99609375.

The missing side of the triangle is x = 8

The scale factor is the size by which the shape is enlarged or reduced. It is used to increase the size of shapes like circles, triangles, squares, rectangles, etc.

Given: the triangle shown in the image, the bigger triangle has been scaled down to the smaller triangle.

In order to find the missing side of the smaller triangle just find the ratio or fraction of the known sides of the bigger triangle and equate it to the corresponding ratio of the sides of the smaller triangle. Thus:

20/15 = x/6            (Note: The scale factor is 20/15)

x/6 = 20/15

15 × x = 20 × 6

15x = 120

x = 120/15 = 8

Let h be the height of the skyscraper.

Then we have:

tan(32∘) = h / 376

Multiplying both sides by 376, we get:

h = 376 x tan(32∘)

h ≈ 214.5 meters

Therefore,

The height of the skyscraper is approximately 214.5 meters.
