a. John's indifference map would show a preference for combinations of eggs and toast where the ratio of toast to eggs is 3:2.

b. Xi's indifference map would show an equal preference for different combinations of bread and chocolate, as she is neutral about bread but views chocolate as a good.

c. Ramesti's indifference map would show perfect substitution between tickets to the opera and baseball games, indicating that he is equally satisfied with either option.

d. Ahmad's indifference map would show a diminishing marginal utility for chocolate bars, where his satisfaction decreases after consuming a certain number of chocolate bars in a day.

which is because:

John's indifference map would consist of curves or lines that represent combinations of eggs and toast where the ratio of toast to eggs is 3:2. Each curve or line represents a different level of satisfaction or utility for John. As he moves further away from his preferred ratio of 3:2, his satisfaction decreases.

Xi's indifference map would show straight lines or curves that represent combinations of bread and chocolate where she is indifferent between different combinations. Since she views chocolate as good and is neutral about bread, the lines or curves would be parallel to the chocolate axis, indicating that she values chocolate more than bread.

Ramesti's indifference map would consist of straight lines that represent perfect substitution between tickets to the opera and baseball games. Any combination of tickets along a line would provide the same level of satisfaction for Ramesti, indicating that he is willing to trade one ticket for the other at a constant rate.

Ahmad's indifference map would show a downward-sloping curve that represents diminishing marginal utility for chocolate bars. As he consumes more chocolate bars in a day, the curve would become flatter, indicating that the additional satisfaction he derives from each additional chocolate bar decreases. This reflects his dislike for chocolates after consuming a certain quantity.

step by step explanation

We need to calculate the definite integral of the function over the interval and divide it by the width of the interval. The average value of the function cos(x) over the interval [0, 2] is approximately 0.909

In summary, to find the average value of the function f(x) = cos(x) over the interval [0, 2], we calculate the definite integral of the function over the interval and divide it by the width of the interval.

To find the definite integral of cos(x) over the interval [0, 2], we can integrate the function:

∫cos(x) dx = sin(x) + C

Evaluating the integral from 0 to 2 gives us:

∫[0 to 2] cos(x) dx = sin(2) - sin(0)

Since sin(0) = 0, we have:

∫[0 to 2] cos(x) dx = sin(2)

To find the average value, we divide this result by the width of the interval:

Average value = (1/2 - 0) * sin(2)

Rounded to three decimal places, the average value of the function cos(x) over the interval [0, 2] is approximately 0.909.

Based on the calculations on the bisector of ST, the value of ST are equal to 38 and 30 respectively.

In order to determine the bisector of a line segment with two (2) endpoints, we would add each point together and divide by two (2).

For exercise 1, we have:

ST = SM + MT

ST = 19 + 19

ST = 38.

For exercise 2, we have:

First of all, we would determine the value of x as follows;

3x - 6 = x + 8

3x - x = 8 + 6

2x = 14

x = 14/2

x = 7.

ST = SM + MT

The volume of the triangular solid is 128/3 cubic units.

The cross-sections of the triangular solid along the y-axis are equilateral triangles with side length equal to the width of the triangular base at that y-coordinate. The width of the triangular base at y = h is equal to 8 - 4h/4. So, the side length of the equilateral triangle at y = h is 8 - 4h/4.

Let's call the height of the equilateral triangle at y = h as "x". Then, using the Pythagorean theorem, we can find the relationship between x and the side length:

x^2 = (8 - 4h/4)^2 - (x/2)^2

Expanding and simplifying the right-hand side:

x^2 = 64 - 16h + h^2/16 - x^2/4

Multiplying both sides by 4:

4x^2 = 256 - 64h + h^2 - x^2

Solving for x^2:

3x^2 = 256 - 64h + h^2

Taking the square root of both sides:

x = √(256 - 64h + h^2)/√3

So, the height of the equilateral triangle at y = h is equal to x = √(256 - 64h + h^2)/√3.

The volume of the triangular solid can be found by integrating the cross-sectional area over the height of the triangular base:

V = (1/3) ∫[0, 4] x^2(y) dy

= (1/3) ∫[0, 4] (√(256 - 64h + h^2)/√3)^2 dh

= (1/3) ∫[0, 4] (256 - 64h + h^2)/3 dh

Evaluating the definite integral:

V = (1/3) * [(256h/3 - 32h^2/2 + h^3/3) |_0^4]

= (1/3) * [(256/3 * 4 - 32/2 * 4^2 + 4^3/3) - (256/3 * 0 - 32/2 * 0^2 + 0^3/3)]

= (1/3) * (256 - 128 + 64/3)

If a nonlinear system of equations contains one linear function that touches the quadratic function at its minimum, then the system has exactly one solution.

This is because the linear function intersects the quadratic function at its minimum point, where there is only one value of x that satisfies both equations.
If a nonlinear system of equations contains one linear function that touches the quadratic function at its minimum, then the system has one unique solution.
Here's a step-by-step explanation:
1. A nonlinear system is a set of equations where at least one of the equations is not linear.
2. In this case, the nonlinear system contains one linear function and one quadratic function.
3. The quadratic function has a minimum point, which is the lowest point of its parabolic graph.
4. The linear function touches the quadratic function at its minimum, which means they intersect at exactly that point.

Step-by-step explanation:

86+79+68+83=316

391-316=75

Answer:

75 newspapers

Step-by-step explanation:

391 is equal to the combination of all the newspapers Nicholas sold over those 5 days. This can be written as an equation:

391 = 86 + 79 + 68 + 83 + x

x represents the number of newspapers Nicholas sold on Thursday.

Now let's solve for x:

First, combine like terms:

391 = 316 + x

now subtract 316 from both sides to isolate x:

391 - 316 = 316 - 316 + x

75 = x

Answer:1 and 3 answer a

Step-by-step explanation:

For a marketing firm which is considering making up to three new hires.

a) The probability that the firm will make at least one hire is equals to the 0.90.

b) The expected value and the standard deviation of the number of hires are 1.57 and 0.78 respectively.

We have a marketing firm is considering making up to three new hires. Let's consider the a random variable X that represents the hiring of candidates. So, possible values of X = 0, 1, 2,3.. Now, The chances of probability of hiring at least two candidates, P( X ≥ 2) = 60% = 0.60

The chances of probability that hiring of none of them = P( X = 0) = 10% = 0.10

The chances of probability that hiring of all of them = P( X = 3) = 5% = 0.05

We have to determine probability that the firm will make at least one hire, P(X ≥ 1).

By probability law, sum of any possible probability values = 1

=> P( X≥ 1 ) = 1 - P( X = 0)

= 1 - 0.10 = 0.90

b) The expected value, E(X), or we say mean μ of a discrete random variable X, is equals to the sum of resultant of multiply each value of the random variable by its probability. The formula is, E ( X ) = μ = ∑ x P ( x )

So, Probability that hiring of exactly two candidates, P( X= 2). As we know, P( X ≥ 2) = 0.60

=> P ( 3) + P (2) = 0.60

=> P(2) = 0.60 - 0.05 = 0.55

Probability that hiring of exactly one candidates, P( X= 1). From, P( X≥ 1 ) = 0.90

=> P( 1) + P ( 3) + P (2) = 0.90

=> P(1) = 0.30

Hence, excepted value, E(X) = ∑ x P ( x )

= 0 × 0.10 + 1× 0.30 + 2× 0.55 + 3× 0.05

= 1.57

Now, standard deviations, σ =√E(X²) - (E(X))²

E(X²) = ∑ x² P ( x )

= 0² ×0.10 + 1² ×0.30 + 2²× 0.55 + 3²× 0.05

= 3.07

so, the standard deviation of the number of hires = √3.07² - 1.57² = 0.78

Hence, required value is 0.78.

The compound interest received by Matthew Westhoven is $51.80

The interest you earn on interest is known as compound interest. Simple math may be used to demonstrate this: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You'll have $110.25 after the second year is over.

Given, the principal amount (P) = $925

Compound interest percentage (r) = 5.5% = 0.055

Time period (t) = 1

Since, it is semiannually compounded (n) = 2*t = 2

Amount (A) = P(1 + r/n)^nt

= 925(1 + 0.055/2)^2

= 925(1.0275)^2

= 925(1.056)

= 976.80

Thus, Interest amount (CI) = A - P

= $976.80 - $925

= $51.80

Answer:

C

Step-by-step explanation:

This looks like a case of multiplying the number of X's by the respective number below it.

For example: the 1/2 has 3 X's, so we multiple (1/2)(3), making it (3/2) or 1.5

Next is the 1 having 2 X's, so (2)(1) is 2

Continuing that trend we get the following

1.5, 4, 2.5, and 3.

So all of our totals are 1.5, 2, 1.5, 4, 2.5, and 3.

Our last step will be adding all these answers together.

1.5 + 2 = 3.5

+ 1.5 = 6

+ 4 = 10

+ 2.5 = 12.5

and finally +3 = a grand total of 15.5 or 15 1/2
