Phillips percentage loss on the trousers is 45.7%.

What is loss percentage?

The term "loss percentage" describes the proportion of loss on any given commodity. Additionally known as percentage loss. When a loss is represented or quantified as a percentage, it is referred to as a loss percentage. The formula for calculating loss percentage is the ratio of losses incurred to costs multiplied by 100 because percentage losses are expressed as a percentage of real cost price.   The area of basic mathematics known as "profit and loss" is concerned with the analysis of the gains and losses incurred in commercial transactions.

Here the cost price of 5 trousers = £ 14 each

Then , Total cost price = 14*5 = £70.

Now he sells 2 pairs for £10 each.

Then selling price of 2 pairs = 2*10 =£20

Now 3 pairs for £6 for each .Then,

Selling price of 3 pairs = 3*6 = £18.

Total selling price of 5 trousers = 20+18=£38.

Now using loss percentage formula ,

=> loss percentage = ( cost price-selling price)/ cost price *100

=> loss percentage = (70-38)/70 *100

=> Loss percentage = 32/70 *100

=> loss percentage = 45.7%.

Therefore Phillips percentage loss on the trousers is 45.7%.

When x is equal to 1, the Function f(x) = -4x - 5 yields a value of -9.

The find ƒ(1) for the function f(x) = -4x - 5, we need to substitute x = 1 into the function and evaluate the expression.

Replacing x with 1, we have:

ƒ(1) = -4(1) - 5

Simplifying further:

ƒ(1) = -4 - 5

ƒ(1) = -9

Therefore, when x is equal to 1, the value of the function f(x) = -4x - 5 is ƒ(1) = -9.

Let's break down the steps taken to arrive at the solution:

1. Start with the function f(x) = -4x - 5.

2. Replace x with 1 in the function.

3. Evaluate the expression by performing the necessary operations.

4. Simplify the expression to obtain the final result.

In this case, substituting x = 1 into the function f(x) = -4x - 5 gives us ƒ(1) = -9 as the output.

It is essential to note that the notation ƒ(1) represents the value of the function ƒ(x) when x is equal to 1. It signifies evaluating the function at a specific input value, which, in this case, is 1.

Thus, when x is equal to 1, the function f(x) = -4x - 5 yields a value of -9.

\(\lim\limits_{h\to 0}\frac{f(6+h) - f(6)}{h} = 2\)

A piecewise function is a function with rules or definition of the function based on the interval of the function.

The equation representing the piece wise function at x → 2⁺, can be found as follows;

Points on the graph of the function are; (3, 2), and (4, 1)

Slope of the graph of the function = (1 - 2)/(4 - 3) = -1

Equation of the function is; y - 2 = -1·(x - 3) = 3 - x

y = 3 - x + 2 = 5 - x

y = 5 - x

y = f(x) = 5 - x

f(x) - 1 = 5 - x - 1 = 4 - x

f(x) - 1 = 4 - x

f(x + 4) = 5 - (x + 4) = 5 - x - 4 = 1 - x

f(x - 4) = 1 - x

\(\frac{f(x) - 1}{f(x + 4)} = \frac{4 - x}{1 - x}\)

The coordinate points on the piecewise function at x → 1⁻ are; (0, 3), and (1, 4)

The slope of the graph is; (4 - 3)/(1 - 0) = 1

The equation is; y - 3 = x

y = f(x) = x + 3

f(f(x) + 1) = f((x + 3) + 1) = f((x + 3) + 3 + 1) = f(x + 7)

f(x + 7)  = (x + 7 + 3) = x + 10

The points on the piecewise function at x = 6 are; (5, 2), and (7, 6)

The slope is; (6 - 2)/(7 - 5) = 2

The interval containing the middle 95% of the data based on the simulation results is approximately (0.35, 0.65), and the observed proportion of 0.55 falls within this interval, indicating that it is within the margin of error of the simulation results.

To create an interval containing the middle 95% of the data based on the simulation results, we can calculate the lower and upper bounds of the interval.

Let's analyze the simulation results and find the appropriate values.

Out of 200 simulations, we observe that the proportion of students who preferred Candidate A ranges from a minimum of 0.35 (35%) to a maximum of 0.65 (65%).

Since the simulations assume a 50-50 split, we can consider these values as the lower and upper bounds for the middle 95% of the data.

To find the range of the middle 95% of the data, we calculate the difference between the upper and lower bounds.

Upper bound: 0.65

Lower bound: 0.35

Range: 0.65 - 0.35 = 0.30  

To find the interval containing the middle 95% of the data, we divide the range by 2 and add/subtract it from the midpoint.

The midpoint is the average of the upper and lower bounds.

Midpoint: (0.65 + 0.35) / 2 = 0.50

Range / 2: 0.30 / 2 = 0.15

Lower bound of the interval: 0.50 - 0.15 = 0.35

Upper bound of the interval: 0.50 + 0.15 = 0.65

Therefore, the interval containing the middle 95% of the data based on the simulation results is approximately (0.35, 0.65).

Now let's compare the observed proportion from the poll to this interval. The poll indicates that out of a random sample of 80 students, 44 students said they would vote for Candidate A.

To calculate the observed proportion, we divide the number of students who preferred Candidate A (44) by the sample size (80).

Observed proportion: 44/80 = 0.55

The observed proportion of 0.55 is within the margin of error of the simulation results.

It falls within the interval (0.35, 0.65), indicating that the observed proportion is consistent with the simulation and aligns with the assumption of a 50-50 split in the population.

Step-by-step explanation:

An equation of the new graph is: A. y = ∣x - 4∣ - 9.

In Mathematics and Geometry, the translation of a graph to the right simply means a digit would be added to the numerical value on the x-coordinate of the pre-image:

g(x) = f(x - N)

Conversely, the translation of a graph downward simply means a digit would be subtracted from the numerical value on the y-coordinate (y-axis) of the pre-image:

g(x) = f(x) + N

Since the parent function y = ∣x∣ was translated 4 units to the right and 9 units down in order to produce the graph of the image, we have:

Step-by-step explanation:

The best estimate for the rate of change of the voltage over the interval will be 3.5 volts. Then the correct option is B.

It is the average amount by which the function is modified per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph that represents the function. The average rate of change of the function is given as,

Average rate = [f(x₂) - f(x₁)] / [x₂ - x₁]

The graph shows the voltage in a circuit changing as temperature increases from 100° to 600°.

We know that v = 1750 at t = 600° and v = 0 at t = 100°. Then the Average rate of change is given as,

Average rate = (1750 - 0) / (600 - 100)

Average rate = 1750 / 500

Average rate = 3.5

  d(t) = 12.133 +2.883sin(2π(t-80)/365.25)

  1.79 fewer hours on Feb 10

Step-by-step explanation:

a) The independent variable is the day number of the year (t), and the dependent variable is daylight hours (d).

__

b) The average value of the sinusoidal function for daylight hours is given as 12 hours, 8 minutes, about 12.133 hours. The amplitude of the function is given as 2 hours 53 minutes, about 2.883 hours. Without too much error, we can assume the year length is 365.25 days, so that is the period of the function,

March 21 is day 80 of the year, so that will be the horizontal offset of the function. Putting these values into the form ...

  d(t) = (average value) +(amplitude)sin(2π/(period)·(t -offset days))

  d(t) = 12.133 +2.883sin(2π(t-80)/365.25)

Answer:

A) - Value that corresponds to surviving the year would be: $-197

- Value Corresponding to not surviving = $98803

B) $-88.1

C) Yes, because the insurance company expects to make an average profit of $88.1 on every 29 year-old male that it insures for 1 year.

Step-by-step explanation:

A) We are told that the life insurance company charges $197 for insuring that the male will live through the year.

Thus, the value that corresponds to surviving the year would be: $-197 since amount that's paid out is $-197

We are told that the policy pays out $100,000 as a death benefit.

Therefore, the value that corresponds to not surviving the year is:

$100000 - 197 = $98803

B) From complement rule in probability;

P(not surviving) = 1 - P(surviving) = 1 - 0.9989 = 0.0011

Expected value would be;

μ = Σx•P(x) = (98803 × 0.0011) + (-197 × 0.9989) = $-88.1

C) Yes, because the insurance company expects to make an average profit of $88.1 on every 29 year-old male that it insures for 1 year.
