The radius and the circumeference of the first semicircle is 6 inches and 18.85 inches².

Given that the diameter of the semi-circle is 12 inches.
The radius is always half the diameter. Therefore, the radius of the given semi-circle is:

Radius of the semicircle = Diameter / 2

= 12 inches / 2

= 6 inches

The circumference of the semicircle is:

Circumference = π × r

= π × 6 in.

= 18.85 in

The area of the purple semicircle:

Area = (π/8) × d²

        = (π/8) × 5²

        = 9.817 inches²

The area of the blue semicircle:

Area = (π/8) × d²

        = (π/8) × 5²

        = 16.085 inches²

Option 1 is the correct answer.

Let's look at our constraint for the y value:

[tex]0\leq y\leq 3[/tex]. Remember that these are greater/lesser than or equal to symbols.

You can tell which way they're facing by what direction they open up in.
In this case, the first opens towards y, and the second opens towards 3.
This means that y is greater than or equal to 0, but lesser than or equal to 3.

This means that y, the vertical axis, can go from anywhere to 0 to 3.
Let's look at the constraint for the x value:

It's [tex]x\geq 0[/tex]. The sign is facing towards x, which means that x is greater than or equal to 0.

This means x (the horizontal axis) can range from 0 to positive infinity.

The y axis will not go above 3, and will not go below 0.
The x axis will not go below 0.

The only graph that satisfies these conditions is Option 1.

The y value does not go past 3, and does not go under 0.

The x value does not go to the left of 0, but goes on forever to the right.

The points that represent this data are shown in the scatter plot attached below.

In this scenario, the age (in years) would be plotted on the x-axis (x-coordinate) of the scatter plot while the hair length (in inches) would be plotted on the y-axis (y-coordinate) of the scatter plot through the use of Microsoft Excel.

On the Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display an equation for the line of best fit (trend line) on the scatter plot.

From the scatter plot (see attachment) which models the relationship between the age (in years) and the hair length (in inches), a linear equation for the line of best fit is given by:

a) If the nth term of sequence 32,-8,2, aₙ = 3aₙ₋₂ - 2aₙ₋₃ and a₁ = 32.

b) If explicit formula is aₙ = -7+10(n-1), a₁ = -7 and aₙ = aₙ₋₁ + 10.

a) a₁ = 32 (the first term of the sequence is given)

aₙ = 3aₙ₋₂ - 2aₙ₋₃ (since the sequence is not arithmetic or geometric, we can use this formula to find the nth term)

So, using this formula, we get:

a₂ = 3(32) - 2(-8) = 104

a₃ = 3(-8) - 2(2) = -26

And so on.

b)

a₁ = -7 (the first term of the sequence is given by the explicit formula)

aₙ = aₙ₋₁ + 10 (since the difference between consecutive terms is 10, we can use this formula to find the nth term recursively)

So, using this formula, we get:

a₂ = a₁ + 10 = 3

a₃ = a₂ + 10 = 13

And so on.

In general, the recursive formula for a sequence gives us a way to generate each term of the sequence based on the previous terms, while the explicit formula gives us a way to calculate any term of the sequence directly.

If the manufacturer's claim is correct, the probability that the average deviation from perfect accuracy would be 34 seconds or more in the sample obtained by the consumer review website is 0.033

We can use a one-sample t-test to test the manufacturer's claim. The null hypothesis is that the true mean deviation from perfect time is equal to 30 seconds per month, and the alternative hypothesis is that the true mean deviation from perfect time is greater than 30 seconds per month.

The test statistic for this one-sample t-test is calculated as follows

t = (x - μ) / (s / √n)

where x is the sample mean, μ is the hypothesized population mean, s is the sample standard deviation, and n is the sample size.

Plugging in the values given in the problem, we have

x = 34 seconds

μ = 30 seconds

s = 15 seconds

n = 40 clocks

t = (34 - 30) / (15 / √40) = 1.89

Using a t-distribution table with degrees of freedom (df) = n-1 = 39 and a significance level of α = 0.05 (one-tailed test), the critical value is 1.686.

Since our calculated t-value (1.89) is greater than the critical value (1.686), we reject the null hypothesis and conclude that the true mean deviation from perfect time is greater than 30 seconds per month.

To calculate the probability that the average deviation from perfect accuracy would be 34 seconds or more in the sample obtained by the consumer review website, we need to find the area under the t-distribution curve to the right of t = 1.89. Using a t-distribution calculator, we find this probability to be approximately 0.033

Based on the mentioned informations and provided values, the price of a square tablecloth with 3.5 m² sides and a cost of €7.25 per square meter is €88.81.

Calculate the price of a square tablecloth with 3.5 m² sides and the square meter of the cost €7.25

The area of the square tablecloth is:

Area = side x side = 3.5 m x 3.5 m = 12.25 m²

To calculate the price of the tablecloth, we need to multiply the area by the cost per square meter:

Price = Area x Cost per square meter

     = 12.25 m² x €7.25/m²

     = €88.81

he theater sold 356 adult tickets and 144 child tickets for a certain showtime to make a total of $3157 in ticket sales.

We have,

Let's assume that the number of adult tickets sold is x, and the number of child tickets sold is y.

We know that the total number of tickets sold cannot exceed the maximum capacity of the theater, so we have the inequality:

x + y ≤ 500

We also know that the total revenue from ticket sales is $3157, so we can write another equation based on the ticket prices:

7.25x + 4y = 3157

We have two equations with two variables, so we can solve for x and y using any method of our choice.

Here, we will use substitution.

We can write,

y ≤ 500 - x.

We can substitute this into the second equation.

7.25x + 4(500 - x) = 3157

Simplifying and solving for x.

7.25x + 2000 - 4x = 3157

3.25x = 1157

x = 355.69

We can't sell a fractional number of tickets, so we must round x to the nearest whole number.

Let's assume that x = 356.

Then, from the first inequality.

356 + y ≤ 500

y ≤ 144

Therefore, we can sell at most 144 child tickets.

To check if this solution satisfies the equation 7.25x + 4y = 3157, we substitute x = 356 and y = 144 into the equation:

7.25(356) + 4(144) = 3157

This is true, so our solution is valid.

Therefore,

The theater sold 356 adult tickets and 144 child tickets for a certain showtime to make a total of $3157 in ticket sales.

To calculate the probability that the trainee class will consist entirely of men, we need to determine the total number of ways to select two people from the pool of ten applicants, as well as the number of ways to select two men from the pool of four men

The total number of ways to select two people from the pool of ten applicants is given by the combination formula

C(10, 2) = 10! / (2! × (10 - 2)!) = 45

This means that there are 45 different ways to select two people from the pool of ten applicants.

The number of ways to select two men from the pool of four men is given by the combination formula

C(4, 2) = 4! / (2! × (4 - 2)!) = 6

This means that there are 6 different ways to select two men from the pool of four men.

Therefore, the probability that the trainee class will consist entirely of men is given by the ratio of the number of ways to select two men from the pool of four men to the total number of ways to select two people from the pool of ten applicants

P(2 men) = C(4, 2) / C(10, 2) = 6/45 = 2/15

Step-by-step explanation:

Given various inscribed angles in a circle, you want the measure of central angle x.

The inscribed angle theorem tells you an arc is double the measure of the inscribed angle it subtends:

  arc JKM = 2·80° = 160°

  arc JNL = 2·126° = 252°

The sum of arcs around a circle is 360°. This tells you ...

  arc JKL = 360° -252° = 108°

An arc has a measure equal to the sum of its parts, so ...

  arc JKM = arc LM +arc JKL

  160° = x + 108°

  x = 52° . . . . . . . . . . subtract 108°
