The equation of circles that have a diameter of 12 units and a center that lies on the y-axis is (x-0)² + (y-3)² = 6²

The standard form for finding the equation of a circle is expressed as;

(x-a)² + (y-b)²=r²

where;

(a, b) is the center of the circle

r is the radius of the circle

Given the following diameter = 12 units

radius = 12/2 = 6 units

If the centre lies on the y-axis, the center will be at (0, 3)

Substituting into the formula, we will have (x-0)² + (y-3)² = 6² equivalent to x²+ (y-3)² = 36

Hence, the equation of circles that have a diameter of 12 units and a center that lies on the y-axis is (x-0)² + (y-3)² = 6²

a) The total amount of money earned is 7.30 dollars.

b) Max is wrong, it is possible to divide the money equally between Gwen and Max, even though the total amount is an odd number.

a) To find the total amount of money earned, we need to convert the number of quarters and dimes to dollars.

6 quarters = 6 * 0.25 = 1.50 dollars

8 dimes = 8 * 0.10 = 0.80 dollars

The total amount of money earned is:

5 dollars + 1.50 dollars + 0.80 dollars = 7.30 dollars

b) Max is incorrect. The total amount of money earned is an odd number ($7.30), which means it is impossible to divide it equally between two people in whole dollar amounts. However, it is possible to divide the total amount equally if we allow for fractions of a dollar.

For example, if we split the money equally, Gwen and Max would each get $3.65. This means that Gwen would get 3 dollars and 65 cents, while Max would also get 3 dollars and 65 cents.

Therefore, it is possible to divide the money equally between Gwen and Max, even though the total amount is an odd number.

The requried coordinate locations of the respective checkpoints at the Reflections of You obstacle course are A' (0,5), B' (9,5), and C' (4,5).

To find the reflected coordinates of each checkpoint in the y-axis, we need to negate the x-coordinate while keeping the y-coordinate the same.

For checkpoint A(0,5), the reflected coordinates A' will be (-0,5) or just (0,5) since reflecting a point over the y-axis does not change its y-coordinate.

For checkpoint B(-9,5), the reflected coordinates B' will be (9,5) since negating -9 gives us 9 and the y-coordinate remains the same.

For checkpoint C(-4,5), the reflected coordinates C' will be (4,5) since negating -4 gives us 4 and the y-coordinate remains the same.

Answer:

If a = -2 and b = 3, then b^a can be calculated as follows:

b^a = 3^(-2)

To find the value of 3^(-2), we can use the rule that says:

a^(-b) = 1 / a^(b)

Thus,

3^(-2) = 1 / 3^2 = 1 / 9

Therefore, the value of b^a, or 3^(-2) is 1/9.

Step-by-step explanation:

a. The solution to the equation f - 13 = 51 is f = 64.

b. The solution to the equation x/10 = 4 is x = 40.

a. f - 13 = 51

Step 1: Add 13 to both sides to isolate f.

f - 13 + 13 = 51 + 13

Step 2: Simplify.

f = 64

Step 3: Check the answer by substituting f = 64 back into the original equation.

64 - 13 = 51

51 = 51

The answer checks out.

b. (x/10) = 4

Step 1: Multiply both sides by 10 to isolate x.

10(x/10) = 4(10)

Step 2: Simplify.

x = 40

Step 3: Check the answer by substituting x = 40 back into the original equation.

40/10 = 4

(–2, 6) are the points that justify the shaded area

We can substitute the values of x and y from each point into the inequality and check if the inequality is satisfied or not.

Let's check each point:

For points (12, 6):

[tex](y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (12+2)^2/24 \\= 49/6 - 196/3 \\= -57.33[/tex]

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

For points (–2, 6):

[tex](y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (-2+2)^2/24 \\= 49/6[/tex]

Here, the value of the expression is greater than or equal to 1, so this point does justify the shaded area.

For points (8, –6):

[tex](y+1)^2/6 -(x+2)^2/24 \\= (-6+1)^2/6 - (8+2)^2/24 \\= 25/6-100/24[/tex]

Here, the value of the expression is greater than or equal to 1, so this point does not justify the shaded area.

For point (–1, –2):

[tex](y+1)^2/6 -(x+2)^2/24 \\= (-2+1)^2/6 - (-1+2)^2/24 \\= 1/6 - 1/24 \\= 1/8[/tex]

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

Answer:

1) The sum of the distances between the points on the ellipse and the foci is constant, whereas the difference between the distances between the points on the hyperbola and the foci is constant.

2) The equation of an ellipse is in the form (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axes, respectively. In contrast, the equation of a hyperbola is in the form (x^2/a^2) - (y^2/b^2) = 1, where a and b are also the lengths of the semi-major and semi-minor axes, respectively, but the difference between a and b determines the shape of the hyperbola.

Step-by-step explanation:

(a) To approximate P(15 < ΣXi < 22), we can use the Central Limit Theorem (CLT) since we have a large enough sample size (n = 30) and the mean and variance of the Poisson distribution are both finite.

First, we need to find the mean and variance of the sample mean, which is also the mean and variance of the Poisson distribution:

μ = λ = 2/3

σ^2 = λ = 2/3

Next, we can standardize the random variable Z = (ΣXi - nμ) / sqrt(nσ^2) to have a standard normal distribution:

Z = (ΣXi - 30(2/3)) / sqrt(30(2/3)) = (ΣXi - 20) / sqrt(20)

Then, we can use a standard normal table or calculator to find the probability:

P(15 < ΣXi < 22) ≈ P(-2.74 < Z < -1.77) ≈ 0.038

Therefore, the approximate probability is 0.038.

(b) To approximate P(21 < ΣXi < 27), we can use the same method with the CLT.

First, we need to find the mean and variance of the sample mean:

μ = λ = 2/3

σ^2 = λ = 2/3

Next, we can standardize the random variable Z = (ΣXi - nμ) / sqrt(nσ^2) to have a standard normal distribution:

Z = (ΣXi - 30(2/3)) / sqrt(30(2/3)) = (ΣXi - 20) / sqrt(20)

Then, we can use a standard normal table or calculator to find the probability:

P(21 < ΣXi < 27) ≈ P(-0.68 < Z < 0.68) ≈ 0.495

Therefore, the approximate probability is 0.495.

Independent-samples t test. This test is used to compare the means of two independent groups. The correct answer is a.

To determine whether the average number of matching characteristics the defense attorney observed (M = 9.8) differs significantly from that reported by fingerprint analysts (16 matching characteristics), she should use a "Single-sample t test".
Here's why:
- The defense attorney is comparing a sample (her 30 cases) to a known population mean (16 matching characteristics).
- The standard deviation of the sample is provided (s = 1.2), but the population standard deviation is not known.

To construct the incenter of a triangle, construct the angle bisectors of each angle of the triangle. Here are the steps to construct the incenter of a triangle:

Draw the three sides of the triangle using a straightedge.

Choose one of the angles of the triangle and draw its bisector. To do this, place the point of your compass on the vertex of the angle, and draw an arc that intersects both sides of the angle. Without changing the width of your compass, place it on each of the two points where the arc intersects the sides of the angle, and draw two more arcs that intersect. The point where these two arcs intersect is the point where the angle bisector meets the opposite side of the triangle.

Repeat step 2 for the other two angles of the triangle. You should now have three lines that intersect at a single point.

The point where all three angle bisectors intersect is the incenter of the triangle.
