The probability of at most one price hike in one year is 0 + 0 = 0.

No price hikes in a randomly selected one and a half year:

The probability of no price hikes in one year is 0, since the average is 4. Therefore, the probability of no price hikes in one and a half years is also 0.

Four price hikes in 2 years:

The average number of price hikes in one year is 4, so the average number of price hikes in 2 years is 8. The probability of exactly 4 price hikes in 2 years is therefore 0, since it is less than the average.

At most one price hike in one year:

The probability of at most one price hike in one year is the sum of the probabilities of 0 and 1 price hikes. The probability of 0 price hikes is 0, as mentioned before. The probability of 1 price hike is also 0, since it is less than the average of 4. Therefore, the probability of at most one price hike in one year is 0 + 0 = 0.

Overall, the probability of no price hikes in a randomly selected one and a half year, four price hikes in 2 years, and at most one price hike in one year are all 0, since they are all less than the average number of price hikes.

The width of the walkway is approximately 0.343 feet or about 4.12 inches.

Let's suppose that the pathway is x feet wide.

The total length of the garden with the walkway is 8 + 2x feet (since there is a walkway on both sides of the garden), and the total width of the garden with the walkway is 12 + 2x feet.

The area covered by the garden and the walkway is the product of the length and width, which is:

[tex](8 + 2x) \times (12 + 2x) = 192[/tex]

Expanding this equation, we get:

[tex]96 + 32x + 16x + 4x^2 = 192\\4x^2 + 48x - 96 = 0[/tex]

Dividing both sides by 4, we get:

[tex]x^2 + 12x - 24 = 0[/tex]

Using the quadratic formula, we get:

x = (-12 ± [tex]\sqrt{ (12^2 - 41(-24))) / (2\times1}[/tex])

x = (-12 ±[tex]\sqrt{(288)) / 2}[/tex])

x = (-12 ± [tex]12\sqrt{(2)) / 2}[/tex]

x = -6 ± [tex]6\sqrt{(2)}[/tex]

Since the width of the walkway cannot be negative, we take the positive value of x:

[tex]x = -6 + 6\sqrt{(2)} \\x= 0.343 feet[/tex]

Therefore, the width of the walkway is approximately 0.343 feet or about 4.12 inches.

If Andy traveled 10 miles and paid a $12 tip to his drive. Sammy traveled 15 miles and paid a $9 tip to his driver. the cost per mile to ride the Uber is $0.60.

Let the cost per mile to ride the Uber be "x".

Then, Andy paid a total of 10x + 12 dollars for his 10-mile trip.

Similarly, Sammy paid a total of 15x + 9 dollars for his 15-mile trip.

Since both customers paid the same amount, we can set their total costs equal to each other and solve for "x":

10x + 12 = 15x + 9

Subtracting 10x and 9 from both sides:

3 = 5x

Dividing by 5:

x = 0.6

Therefore, the cost per mile to ride the Uber is $0.60.

The following solutions with regard to resolving or simplifying the radii of the circular pond are given below.

Part A: 5√100 + √164 meters = 5 × 10 + 2√41 meters

Part B: 5 × 10 + 2√41 meters = 50 + 2√41 meters

Part C: The radius of Pond B is 10√2 meters.

Part D: the radius of Pond B is greater than the radius of Pond A.

Part A: The mistake is in Step 1. To simplify the square root of 164, we need to find its prime factors:

164 = 2 × 2 × 41

So, we can write:

√164 = √(2 × 2 × 41) = 2√41

Using this, we can rewrite Step 1 as:

5√100 + √164 meters = 5 × 10 + 2√41 meters

Part B: Using the corrected step from Part A, we can simplify the radius of Pond A as:

5 × 10 + 2√41 meters = 50 + 2√41 meters

So, the radius of Pond A is 50 + 2√41 meters.

Part C: The radius of Pond B is already simplified, so we don't need to do any additional steps. It is:

25√200/5 meters = 5√200 meters

We can simplify this further by finding the prime factorization of 200:

200 = 2 × 2 × 2 × 5 × 5

So, we can write:

√200 = √(2 × 2 × 2 × 5 × 5)

= 2 × 5√2

Using this, we can rewrite the expression for the radius of Pond B as:

5 × 2 × √2 meters

= 10√2 meters

Thus, the radius of Pond B is 10√2 meters.

Part D: We can compare the radii of the ponds using the original expressions by writing:

√164 < 25√200/5

Simplifying both sides:

2√41 < 10√2

Dividing both sides by 2:

√41 < 5√2

Squaring both sides (since both sides are positive):

41 < 25 × 2

41 < 50

So, the inequality is true. Therefore, the radius of Pond B is greater than the radius of Pond A.

Shante rides at an average speed of 9.33 miles per hour.

We need to determine how many miles Shante rode per hour. We can set up an equation to solve this problem:

3 hours x M (miles per hour) = 29 miles

7 hours x M = 65 miles

We can then solve this equation to find out the number of miles she rode per hour:

3M = 29

M = 29/3

M = 9.67 miles per hour.

Therefore, Shante rode at an average rate of 9.67 miles per hour.

Now, we can find her average speed by dividing the total distance she has traveled by the total time she has traveled:

Therefore, Shante rides at an average speed of 9.33 miles per hour.

The measures of the angles in the triangle are A = 6.17°,B = 11.50°, C = 162.33° and that's the solution to the triangle using the Law of Sines.

To solve the triangle using the Law of Sines, we can use the following formula:

(a/sin A) = (b/sin B) = (c/sin C)

First, let's convert the given angle B from degrees and minutes to decimal form:

B = 11° 30' = 11.5°

Next, we can plug in the given values into the formula and solve for the unknowns:

(3.7/sin A) = (6.5/sin 11.5°)

Cross-multiplying and rearranging gives us:

sin A = (3.7 * sin 11.5°) / 6.5

Using a calculator, we can find the value of sin A:

sin A = 0.1076

Now, we can use the inverse sine function to find the measure of angle A:

A = sin^-1(0.1076) = 6.17°

Finally, we can use the fact that the sum of the angles in a triangle is 180° to find the measure of angle C:

C = 180° - A - B = 180° - 6.17° - 11.5° = 162.33°

So, the measures of the angles in the triangle are:

A = 6.17°
B = 11.5°
C = 162.33°

Round your answers to two decimal places, we have:

A = 6.17°
B = 11.50°
C = 162.33°

The amount that you owe will reach $15,000 after approximately 21.5 years.

Here is a step-by-step explanation of how to calculate this:
1. First, determine the number of compounds per year (n). In this case, since we are using an effective rate, n = 1.
2. Next, use the compound interest formula to find the final amount (A): A = P(1 + r/n)^(nt)
3. Plug in the given values for P ($10,000), r (0.021), n (1), and A ($15,000) and solve for t:
$15,000 = $10,000(1 + 0.021/1)^(1*t)
4. Simplify the equation and isolate t on one side:
1.5 = (1.021)^t
5. Take the natural logarithm of both sides:
ln(1.5) = t*ln(1.021)
6. Solve for t:
t = ln(1.5)/ln(1.021)
7. Use a calculator to find the value of t:
t ≈ 21.5

The cosine value of θ is approximately -0.7071.

We know that:

sin(θ) = √(3/2)

Using the trigonometric identity:

sin^2(θ) + cos^2(θ) = 1

We can find cos(θ) by first finding sin^2(θ) and then solving for cos(θ):

sin^2(θ) + cos^2(θ) = 1

cos^2(θ) = 1 - sin^2(θ)

cos(θ) = ± √(1 - sin^2(θ))

Since cos(θ) is negative, we can choose the negative square root:

cos(θ) = - √(1 - sin^2(θ))

Substituting sin(θ) = √(3/2), we get:

cos(θ) = - √(1 - 3/2)

cos(θ) = - √(1/2)

cos(θ) = - √2/2

Since cos(θ) is negative and given cos(θ) < 0, we have:

Loni needs to do 4,450 sessions in the first year to break even.

What is total revenue?

Total revenue is the total amount of money earned by a business from the sale of its products or services during a particular period of time.

To break even, the total revenue Loni makes should be equal to the total cost of running the nail salon. Let's calculate the total cost first:

Total Cost = Rent + Other expenses + Start-up cost + Cost of supplies per session x Number of sessions

Total Cost = $24,000 + $50,000 + $15,000 + $10 x Number of sessions

Total Cost = $89,000 + $10 x Number of sessions

Now, to break even, the total revenue should be equal to the total cost:

Total Revenue = Total Cost

$30 x Number of sessions = $89,000 + $10 x Number of sessions

$20 x Number of sessions = $89,000

Number of sessions = $89,000 / $20

The radius of the circle is approximately 5.861 cm, and the area of the circle is approximately 107.76 cm².

A regular polygon is one that has an equal number of sides and angles. Each vertex of a regular polygon is located on a shared circle known as the circumscribed circle or circumcircle. A circumscribed circle or circumcircle of the polygon, on the other hand, is any circle that goes through every vertex of the polygon. The circumradius of the polygon is the circumference of the circle. The circumradius is the distance from the centre to any vertex of a regular polygon with n sides, and the circumcircle's centre coincides with the polygon's centre.

Given that, the hexagon is regular, angle AOB is 60 degrees.

The side AB is given as 8cm.

Using trigonometric functions we have:

h = r * cos(30 degrees) = (√(3)/2) * r.

Now using the Pythagoras theorem:

OB² = AB² - h².

Substituting the value of h:

OB² = 8² - (√(3)/2)² * r².

OB² = 64 - (3/4) * r².

OB = √(64 - (3/4) * r²).

Here, OB is equal to the radius of the circle.

r = √(64 - (3/4) * r²) = 5.861 cm.

 The solution to the system of equations is (x, y) = (-5/3, -4/3).

What is system of linear equations?

A system of linear equations is a set of two or more equations with two or more variables that are to be solved simultaneously. Each equation in the system is linear, meaning it can be written in the form of ax + by + cz + ... = d, where a, b, c, and d are constants and x, y, z, and other variables are unknowns.

The goal of solving a system of linear equations is to find the values of the variables that satisfy all of the equations in the system. The solution of a system of linear equations is a set of values for the variables that make all of the equations true.

There are different methods to solve systems of linear equations, such as substitution method, elimination method, and matrix method. These methods involve manipulating the equations in the system to isolate one variable, substitute its value into another equation, and eventually find the values of all the variables.

Systems of linear equations are used in many areas of mathematics, science, engineering, and economics to model real-world situations and solve practical problems.

To solve the system of equations:

x + y = -3 (Equation 1)

y = 2x + 2 (Equation 2)

We can substitute Equation 2 into Equation 1 for y and solve for x:

x + (2x + 2) = -3

3x + 2 = -3

3x = -5

x = -5/3

Now that we know x, we can substitute it into either Equation 1 or Equation 2 to find y. Let's use Equation 2:

y = 2x + 2

y = 2(-5/3) + 2

y = -10/3 + 6/3

y = -4/3

Therefore, the solution to the system of equations is (x, y) = (-5/3, -4/3).

Comparing this solution to the answer choices, we see that option (b) is the correct answer:

(a) 5/3, 4/3
