The equation of the sphere will be: xz = (x-2)^2 + (z-4)^2 = -11

What is the equation of a sphere?

The general equation of a sphere is: (x - a)^2 + (y - b)^2+ (z - c)^2 = r^2, where (a, b, c) equals the center of the sphere, r= radius, and x, y, and z are the coordinates of the points on the surface of the sphere respectively.

The general equation will be

(x - 2)^2 + (y - 6)^2+ (z - 9)^2 = 25

xy plane: (x - 2)^2 + (y -+6)^2 = 9

xz plane: (x - 2)^2 + (z - 4)^2 = -11

yz plane:  (y +6)^2+ (z - 4)^2 = 21

Therefore, the equation will be xz = (x-2)^2 + (z-4)^2 = -11  because it does not intersect the XZ plane.

In conclusion, the equation of a sphere can be found using general equation.

The joint probability mass function of X and Y, representing the number of pages with moderate and high graphics output respectively, is as follows:

P(X=0, Y=0) = 0.2948, P(X=0, Y=1) = 0.3752, P(X=1, Y=0) = 0.1452, P(X=1, Y=1) = 0.1848, P(X=2, Y=0) = 0.1452, P(X=2, Y=1) = 0.1848.

To find the joint probability mass function (PMF) of X and Y, we need to consider all possible combinations of X and Y and calculate their probabilities.

Let's denote the events as follows:

A: Page with moderate graphics output

B: Page with high graphics output

Given:

P(A) = 0.33 (probability of a page having moderate graphics)

P(B) = 0.56 (probability of a page having high graphics)

P(not A) = 1 - P(A) = 0.67 (probability of a page not having moderate graphics)

P(not B) = 1 - P(B) = 0.44 (probability of a page not having high graphics)

We are selecting 2 pages with replacement, so each selection is independent.

Now, let's calculate the joint probabilities for all possible combinations of X and Y:

When X = 0 and Y = 0:

P(X = 0, Y = 0) = P(not A) * P(not B) = 0.67 * 0.44 = 0.2948

When X = 0 and Y = 1:

P(X = 0, Y = 1) = P(not A) * P(B) = 0.67 * 0.56 = 0.3752

When X = 1 and Y = 0:

P(X = 1, Y = 0) = P(A) * P(not B) = 0.33 * 0.44 = 0.1452

When X = 1 and Y = 1:

P(X = 1, Y = 1) = P(A) * P(B) = 0.33 * 0.56 = 0.1848

When X = 2 and Y = 0:

P(X = 2, Y = 0) = P(A) * P(not B) = 0.33 * 0.44 = 0.1452

When X = 2 and Y = 1:

P(X = 2, Y = 1) = P(A) * P(B) = 0.33 * 0.56 = 0.1848

All other combinations where X or Y is greater than 2 will have a probability of 0 since there are only 100 pages in total.

Therefore, the joint probability mass function of X and Y is:

P(X, Y) =

X=0, Y=0: 0.2948

X=0, Y=1: 0.3752

X=1, Y=0: 0.1452

X=1, Y=1: 0.1848

X=2, Y=0: 0.1452

X=2, Y=1: 0.1848

A perfect square trinomial factors to a binomial squared, option a.

A perfect square trinomial is a trinomial expression that can be factored into the square of a binomial. It has the form:

(ax² + bx + c)²

To factor it, you can take the square root of the first term (ax²) and the square root of the last term (c). The middle term (bx) will be twice the product of these square roots. Therefore, the factored form of the perfect square trinomial is:

(ax² + bx + c)² = (√(ax^2) + √(c))² = (√(ax^2) + √(c))(√(ax^2) + √(c))

This can be simplified to:

(ax² + bx + c)² = (√(ax²) + √(c))² = (√(a)x + √(c))²

So, a perfect square trinomial factors into the square of a binomial, where the first term of the binomial is the square root of the coefficient of the squared term, and the second term is the square root of the constant term.

Answer: $1.50

Step-by-step explanation:

      The 10% tip will be 10% of the total meal cost. Of means multiplication so we can set up an equation, keeping in mind that a percent divided by 100 becomes a decimal.

10% * $14.95 = 0.1 * $14.95 = $1.495 ≈ $1.50

The value of the perpetuity today, with an annual interest rate of 8%, is $4,125.25.

To calculate the present value of a perpetuity, we can use the formula: Present Value = Cash Flow / Interest Rate.

In this case, the cash flow is $500 per year, and the interest rate is 8% (or 0.08 in decimal form). Plugging these values into the formula, we get: Present Value = $500 / 0.08 = $6,250.

However, this calculation gives us the present value of the perpetuity starting from today. Since the payments start 5 years from today, we need to discount the value by the present value of $1 received 5 years from today.

Using the formula for the present value of a single amount, we find that the present value of $1 received 5 years from today, with an 8% interest rate, is approximately 0.6806.

To calculate the present value of the perpetuity starting 5 years from today, we multiply the present value of $6,250 by the discount factor of 0.6806: Present Value = $6,250 * 0.6806 ≈ $4,250.25.

Therefore, the value of the perpetuity today, with an 8% annual interest rate and payments starting 5 years from today, is approximately $4,125.25.

Answer: 5.15

Step-by-step explanation: I put it in my calculator(?)

There are 360 black counters and 306 white counter in 20:17 ratio.

Let's denote the number of black counters by B and the number of white counters by W. We know that the ratio of black to white counters is 20:17, which means that:

B/W = 20/17

We also know that there are 54 more black counters than white counters, which means that:

B = W + 54

We can use substitution to solve for B. Substituting the second equation into the first equation, we get:

(W + 54)/W = 20/17

Cross-multiplying, we get:

17(W + 54) = 20W

Expanding the left side, we get:

17W + 918 = 20W

Subtracting 17W from both sides, we get:

918 = 3W

Dividing both sides by 3, we get:

W = 306

Now we can use the second equation to find B:

B = W + 54 = 306 + 54 = 360

Therefore, there are 360 black counters in the bag.

The median for data set 1 is 86. The median for data set 2 is 77.5. The IQR for data set 1 is 7. The IQR for data set 2 is 6. The set with more consistent data is data set 2.

Step-by-step explanation:

Data set 1

{82, 89, 70, 85, 93, 87}

median:

step 1: place the data set numbers in order

70, 82, 85, 87, 89, 93

step 2: n + 1 / 2                     n is the number of terms

6 + 1 / 2 = 7 / 2 = 3.5            this means the 3.5 number in the data set

between 85, 87                    85 + 87 / 2 = 86

median = 86

IQR:

formula: IQR = Q3 - Q1

Q3 = median of the upper bound of 87, 89, 93

Q3 = 89

Q1 = median of the lower bound of 70, 82, 85

Q1 = 82

IQR = Q3 - Q1 → 89 - 82 = 7

Data set 2

{73, 77, 72, 79, 81, 78}

median:

step 1: place the data set numbers in order

72, 73, 77, 78, 79, 81

step 2: n + 1 / 2                     n is the number of terms

6 + 1 / 2 = 7 / 2 = 3.5            this means the 3.5 number in the data set

between 77, 78                    77 + 78 / 2 = 77.5

median = 77.5

IQR:

formula: IQR = Q3 - Q1

Q3 = median of the upper bound of 78, 79, 81

Q3 = 79

Q1 = median of the lower bound of 72, 73, 77

Q1 = 73

IQR = Q3 - Q1 → 89 - 82 = 6

other possible calculation for these data sets

Finding the mean:

formula: sum of the data set / total number of terms

sum of the data set: 82 + 89 + 70 + 85 + 93 + 87 = 506

total number of terms: there is 6 numbers in the data set

mean = 506 / 6

Dimensions of the product matrix = (3 × 3)

Step-by-step explanation:

If matrix P having dimensions (m × n) and matrix Q having dimensions (n × r) are multiplied,

Dimensions of the product matrix PQ will have the dimensions as (m × r).

That means product of the two matrices are defined when columns of first matrix P is equal to the rows of the second matrix Q.

Following this rule,

Dimensions of matrix A = (2 × 3)

[ Rows × Columns]

Dimensions of matrix B = (3 × 3)  [Rows of B = 3, columns of B = 3]

Dimensions of matrix C = (3 × 2) [Rows of C = 3, columns of C = 2]

Since columns of C and rows of A are equal.

Therefore, product of C and A is defined.

Product of the matrices C & A will have the dimensions as (3 × 3).

The measure of angle are:

m∠1 = 35°; m∠2= 125°; m∠3= 55°; m∠4 =125° ; m∠5 =55°.

What are similar triangles?

Similar triangles are triangles that have the same shape but differ in size. Similar objects include all equilateral triangles and squares with any side length. In other words, if two triangles are similar, their corresponding angles and sides are congruent and in equal proportion.

The △ABC is a right triangle.

Given that, 2AE = AC, 2CD = BD

AE/AC = 1/2; CD/BD = 1/2

∠ACD = ∠ECD = right angle

According to SAS rule, △ABC ≅ △ECD.

Thus the corresponding angles of △ABC and △ECD are congruent.

∠A = ∠E; ∠B = ∠D; ∠C = ∠C

Consider  △ABC:

∠A = 35°, ∠C =90°

The sum of all interior angles of a triangle is 180°.

∠A + ∠B + ∠C = 180°

35° +  ∠B + 90° = 180°

∠B + 125° = 180°

∠B  = 180° -  125°

∠B  = 55°

Therefore ∠1 = 55°; ∠5 = 55°; ∠3 = 55°.

The sum of the exterior angle and corresponding to the interior angle is 180°.

∠1  + ∠2 = 180°

55° + ∠2 = 180°

∠2 = 125°

Again:

∠5  + ∠4 = 180°

55° + ∠4 = 180°

∠4 = 125°

When there is a minus (-) in front of a parenthesis, all signs change inside it:

\(3y+9+14y-56-y+1)=0\\\)

Now we operate:

\(16y-46=0\)

We add 46 on both sides:

\(16y - 46 + 46 = 0 +46\)

\(16y = 46\)

And divide 16 on both sides:

Answer:

85.33ft2

Step-by-step explanation:

Given statement solution is:-The bearing of City C from City B is approximately 76.14°.

To solve this problem, we can use the law of cosines and trigonometry to find the distance and bearing between City B and City C.

Let's start with calculating the distance between City B and City C.

i. Distance between City B and City C:

We can form a triangle ABC with sides AB, BC, and AC.

Given:

AB = 22m (distance between City A and City B)

AC = 33m (distance between City A and City C)

To find BC (distance between City B and City C), we can use the law of cosines:

\(BC^2 = AB^2 + AC^2 - 2 * AB * AC *\) cos(angle BAC)

Angle BAC can be found by subtracting the bearing of City A from City C (018°) from 180° since they are on opposite sides of City B:

Angle BAC = 180° - 018° = 162°

Now, let's calculate BC using the law of cosines:

\(BC^2 = 22^2 + 33^2 - 2 * 22 * 33 *\) cos(162°)

Using a calculator, we can evaluate the right side of the equation:

\(BC^2\) ≈ 484 + 1089 + 1452.43 ≈ 3025.43

Taking the square root of both sides, we get:

BC ≈ √3025.43 ≈ 55.01m

Therefore, the distance between City B and City C is approximately 55.01m.

ii. Bearing of City C from City B:

To find the bearing of City C from City B, we need to determine the angle formed by the line connecting City B and City C with respect to the north direction.

Since we know the distances AB and BC, we can use trigonometry to find the angle.

tan(angle B) = BC / AB

Let's calculate the angle:

angle B ≈ arctan(BC / AB) ≈ arctan(55.01 / 22)

Using a calculator, we find:

angle B ≈ 68.86°

However, this gives us the bearing of City C from City B. To find the bearing of City C from City B, we need to subtract this angle from the bearing of City B.

Bearing of City C from City B = 145° - 68.86°

Bearing of City C from City B ≈ 76.14°

Therefore, the bearing of City C from City B is approximately 76.14°.
