The scale factor used to create the travel version of the piece is 1: 0.16

0.6 is the scale factor used to reduce the dimensions of the original piece having sides measuring 3 inches each.

Scale factor is calculated by dividing the new reduced scale by original scale. Hence:

0.5/3 = 0.166

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Scale Factor = New Shape Dimension / Original Shape Dimension

Enlarging a small form into a huge one is known as scaling up. Upscaling always uses a scale factor greater than 1. A scale factor 2 means the figure is enlarged twice the original figure's size.

A large number gets scaled down in order to become a smaller one. Scaling down always results in a scale factor less than 1.

The simplified numerator of the sum is 4x + 6

Given,

We have the following expression for this situation:

x / (x² + 3x + 2) + 3/(x + 1)

And here's where we can start:

x(x + 1) + 3(x² + 3x + 2) / (x² + 3x + 2) (x + 1)

We may now factor the terms x² + 3x + 2 = (x + 1) (x + 2) on the denominator and distribute the terms on the numerator to get:

x² + x + 3x² + 9x + 6 / (x + 2) (x + 1)²

4x² + 10x + 6 / (x + 2) (x + 1)²

Now, the numerator can be factored as follows:

4x² + 10x + 6 = (2x + 2) (2x + 3)

And if we substituted that, we got:

(2x + 2) (2x + 3) / (x + 2) (x + 1)²

We can now apply common factor 2 to the numerator as follows:

2(x + 1) (2x + 3) / (x + 2) (x + 1)²

Additionally, the x+1 can be cancelled on the numerator and denominator as follows:

2(2x + 3) /  (x + 2) (x + 1) = 4x + 6/ (x + 2) (x + 1)

Therefore,

The marginal revenue in the interval between six and seven jet skis is $300.

Here we are given that total revenue from six jet skis is $2,400

and total revenue from seven jet skis is $2,700

Now, marginal revenue is defined as the revenue gained or lost by producing one more additional unit of a good.

Here, the total revenue increases from $2,400 to $2,700 as we go from producing 6 jet skis to 7 jet skis.

Thus, the change in total revenue will be-

2700 - 2400

= 300

The circle is partitioned into 9 parts and arc GH is only one of the parts, therefore, the length of arc GH is a ninth of the circumference of the circle which has the radius as a factor.

The circumference of a circle is the perimeter of the circle which is equal to the product of twice the radius and π.

The circumference of the circle is C = 2·π·r

The circle is divided into 9 parts

The arc GH is the arc to one part of the circle

The length of the arc GH = 2·π·r/9

The ratio of the arc GH to the radius, r = n is therefore;

When r = n,

Measure of arc length [tex]\widehat{GH}[/tex] = 2·π·n/9

Ratio of [tex]\widehat{GH}[/tex] to r = n is obtained using the formula;

A sample of 81 business students over a one-week period with the population standard deviation is 1.2 hours. We calculate the following using the standard formulae:

a) Standard error of the mean is 0.13.

b) Margin of error is 0.975.

c) If the sample mean is 9 hours, then 95% confidence interval is (8.608 , 9.392).

Confidence Interval

The error introduced during the random sampling process is the sampling error described in the estimation procedure in the form of margin of error (MOE). MOE is expressed by the following formula:

MOE = CV ×SE

where,

CV = critical value of distribution

SE = standard error Solution

Note that, Population standard deviation(σ) is known. So we use z distribution.

we have given that

Sample size, n = 81

Standard deviations, σ = 1.2 h

a)

Standard error = σ /√n

=> S.E = 1.2/√81 = 1.2/9

=> S.E = 0.13

b) We have to construct 95% confidence interval.

therefore, c = 0.95

=> α= 1 - c = 1- 0.95 = 0.05

then, α/2 = 0.05/2 = 0.025 and 1- α/2 = 0.975

the probability or P-vale is 0.975 then from Z-table the corresponding z value is 1.96

The margin of error formula:

MOE = Zα/2 (σ/√n)

= 1.96 (0.13 )

= 0.2548

Margin of error = 0.2548

c) Now , confidence interval for mean(u) formula

(X-bar - E ) < μ < (X-bar + E)

=> ( 9 - 0.392) < μ < (9 + 0.392)

=> 8.608 < μ < 9.392

=>(8.608 , 9.392)

Hence, standard error is 0.13

Margin of error is 0.2548 and confidence interval is (8.608 , 9.392).

Such that

x = Number of years after 2003 and y is the amount of cheese

The value of x can be calculated using

x = year - 2003

Substitute 2006 for year

x = 2006 - 2003

Evaluate

x = 3

Substitute x = 3 in the equation y = 7(1.03)ˣ

y = 7(1.03)³

Evaluate

y = 7.7

In the year 2014, the value of x is calculated as

x = Current year - 2003

So, we have

x = 2014 - 2003
