The type of sampling used to judge the appeal of the television sitcom is a b) stratified sample.

A stratified sample is a type of sampling where the population is divided into subgroups or strata based on certain characteristics, and then a random sample is taken from each of these strata. In this case, the population is divided into three age categories and a random sample of 10 people is selected from each category.

Stratified sampling is useful when the characteristics of each stratum are different and you want to make sure that the sample accurately reflects the entire population. By dividing the population into age categories, this method ensures that the sample is representative of the different age groups and their opinions on the pilot show.

Overall, stratified sampling is a useful method for accurately estimating the characteristics of a population by taking into account any relevant differences within it.

Answer: A line parallel to the x-axis and at a distance of 7 units above the x-axis.

Answer:

(a) The number of tiles Jon will use to cover the worktop is 6 * 15 = 90 tiles.

(b) To find the length of the worktop, we first need to find the length of each tile, which is 20 cm = 0.2 m.

The length of the worktop is then 0.2 m * 6 tiles = 1.2 m.

The width of the worktop is 0.2 m * 15 tiles = 3 m.

So, the length of the worktop is 1.2 m and the width is 3 m.

Income normally uses a ratio scale of measurement.

Hence, option (a) is correct choice.

A ratio scale is a numerical scale with a genuine zero and equal gaps between adjacent points. A zero on a ratio scale, unlike an interval scale, indicates the complete absence of the variable being measured. Ratio scales include length, area, and population.

A ratio scale may be used to label variables, arrange them in order, and calculate the equal distance between variables. The ratio Scale enables unit conversion. British thermal units, such as Joules, kilograms, and grams, are ratio scale units.

As several elements of a given unit, interval scale may quantify size and magnitude. A ratio scale can be used to quantify size and magnitude by dividing one designated unit by another.

The farthest point from P is point U with a distance of 6.4 units

From the question, we have the following parameters that can be used in our computation:

P = (-1, 3)

To determine the farthest point, we make use of the distance formula represented as

distance = √[(y₂ - y₁)² + (x₂ - x₁)²]

So, we have

PR = √[(4 - 3)² + (2 + 1)²] = 3.2

PS = √[(1 - 3)² + (-4 + 1)²] = 3.6

PT = √[(5 - 3)² + (0 + 1)²] = 2.2

PU = √[(-2 - 3)² + (3 + 1)²] = 6.4

a) The Nash Equilibrium is when both players put in the same effort level x1 = x2 = x.

b) The total payoff is a convex function of x1, which means that increasing x1 will always increase the total payoff.

a. Nash Equilibrium: A Nash Equilibrium is a set of strategies such that each player's strategy is a best response to the strategies of the other players.

In this game, each person i chooses their effort level x i to maximize their own payoff, which is the worth of the project divided by 2. Their individual payoff is given by:

pi = (2x1x2) / 2 = x1x2

By taking the derivative of pi with respect to xi and setting it to zero, we get the following first-order condition:

dpi/dx i = x2 - xi = 0

Since xi is in the range [0,1], we have xi = x2.

Thus, the Nash Equilibrium is when both players put in the same effort level x1 = x2 = x.

b. Total Payoff: The total payoff of the project is given by:

pt = x1x2 + x1x2 = 2x1x2

By factoring the total payoff function, we get:

pt = 2x1x2 = 2x1x1 = 2x12

So, the total payoff is a convex function of x1, which means that increasing x1 will always increase the total payoff.

Since the Nash Equilibrium is when both players put in the same effort level, there is no effort level that yields a higher total payoff than the Nash Equilibrium.

The profit function is P ( x ) = 2x² + 5x - 12 and the number of months during which the company is not making a profit is x = 1.5 years = 18 months

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the profit function be represented as P ( x )

Let the cost function of the company be C ( x ) = 17 - 8x - 2x²

Let the revenue function of the company be R ( x ) = 5 - 3x

Now , Profit = Revenue - Costs

Substituting the values in the equation , we get

P ( x ) = R ( x ) = C ( x )

P ( x ) = 5 - 3x - ( 17 - 8x - 2x² )

On simplifying the equation , we get

P ( x ) = 2x² + 5x - 12

Now , when the profit of the company is 0

2x² + 5x - 12 = 0

On factorizing the equation , we get

2x² + 8x - 3x - 12 = 0

2x ( x + 4 ) - 3 ( x + 4 ) = 0

Taking the common factors of the equation , we get

( 2x - 3 ) ( x + 4 ) = 0

The value of x cannot be negative , so

2x - 3 = 0

Adding 3 on both sides of the equation , we get

2x = 3

Divide by 2 on both sides of the equation , we get

x = 3/2 years

Answer: We can set up an equation to represent the given information:

4.563 = 4B + 127

where B is the number of residents in Town B.

To solve for B, we can first subtract 127 from both sides:

4.563 - 127 = 4B

Then divide both sides by 4:

B = (4.563 - 127) / 4

B = 1.140775

Answer:

  ±320

Step-by-step explanation:

You want the 4th term of the geometric progression that has first and third terms 5 and 80.

The general term of a geometric sequence is ...

  an = a1·r^(n-1)

for first term a1 and common ratio r.

We are given the 1st and 3rd terms, so we can find the common ratio from ...

  80 = 5·r^(3-1) . . . . . use a3 = 80, a1 = 5, n = 3

  16 = r^2 . . . . . . divide by 5

  ±4 = r . . . . . . . . take the square root

The 4th term will be the product of the 3rd term and the common ratio:

  a4 = a3·(±4) = 80·(±4) = ±320

The fourth term is -320 or +320.
