Similarities:

- both have a variable to the exponent 0 (anything to the power of 0 = 1)

         y = b(x^0)     and     x = b(y^0)     where b is any real number

- they are both in the form of a variable being equal to a number

Differences:

- they are perpendicular

- vertical lines are x = b (no y in the equation) whereas horizontal lines

The value of p-hat (the sample proportion) is 0.24, or 24% if total number of skittles in a sample is 300 out of which 72 skittles are purple.

The sample proportion, denoted by p-hat, is the proportion of purple skittles in the sample. We can calculate p-hat by dividing the number of purple skittles by the total number of skittles in the sample

p-hat = number of purple skittles / total number of skittles in sample

In this case, we have

Number of purple skittles = 72

Total number of skittles in sample = 300

Therefore,

p-hat = 72/300 = 0.24

Another possible vertex of the square is determined as (2, 1).

option B is the correct answer.

The vertex of a figure is the point of intersection of two sides of the shape.

The perimeter of the square is given as 12 units, the length of each side of the square is calculated as follows;

P = 12 units

a side length = 12 units / 4 = 3 units

To determine another possible vertex of the square, the length between the points must be equal to 3.

Let's consider point A;

A = (1, 2)

given vertex = (-1, 1)

distance between the points = √ (-1 -1)² + (1 - 2)² = √5

Let's consider point B;

B = (2, 1)

given vertex = (-1, 1)

distance between the points = √ (-1 -2)² + (1 - 1)² = √9 = 3

Thus, point B is another possible vertex of the square.

Problem involves determining expected gain or loss for NC Mutual Life Insurance based on the probability of a 60-year-old woman dying within one year and the purchase of a $10,000 one-year term policy for $600.

We need to calculate the expected gain or loss for the insurance company.To calculate the expected gain or loss, we need to consider the probability of the insured woman dying within one year and the payout from the insurance policy.

Given that the probability of the woman dying within one year is 0.5, we can assume that there is a 50% chance of a payout.If the woman dies within one year, the insurance company will have a loss of $10,000 since they have to pay out the policy amount.

If the woman does not die within one year, the insurance company will have a gain of $600 since they have received the premium amount.To calculate the expected gain or loss, we multiply the probability of a payout (0.5) by the loss amount (-$10,000) and the probability of no payout (0.5) by the gain amount ($600). Then we sum these two values:

Expected Gain or Loss = (0.5 * -$10,000) + (0.5 * $600)

Simplifying the equation gives us the expected gain or loss for North Carolina Mutual Life Insurance.

The rankings are determined by different sets of criteria and can fluctuate from week to week based on the teams' performances. Therefore, the theorem does not apply in this situation.

The Intermediate Value Theorem states that if a function is continuous on a closed interval, it must take on every value between the function's endpoints at least once. In this case, we are not dealing with a function, but rather with rankings that are determined by subjective opinions and various factors such as wins, losses, and strength of schedule. While it may seem contradictory for the football team to be ranked lower than the basketball team at one point and then ranked higher later on without ever being ranked the same, it is not a violation of the Intermediate Value Theorem since the rankings are not continuous and do not follow a specific function.

Answer:

1) 0.75

2) y = \(\frac{3}{4}\)x - 3

3) (4, 0); (0, -3)

Step-by-step explanation:

Convert to slope-intercept form (y = mx + b) by solving:

y = \(\frac{3}{4}\)x - 3

m is the slope, so \(\frac{3}{4}\) or you can write as 0.75.

To find the x and y intercepts, set the y value to zero and solve (x-intercept), and b is the y-intercept.

Answer:

θ = \(\frac{\pi }{3}\) (60° )

Step-by-step explanation:

Using the identity

sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Given

cos²θ - sin²θ = 2 - 5cosθ

cos²θ - (1 - cos²θ) = 2 - 5cosθ

cos²θ - 1 + cos²θ = 2 - 5cosθ

2cos²θ - 1 = 2 - 5cosθ ( subtract 2 - 5cosθ from both sides )

2cos²θ + 5cosθ - 3 = 0 ← in standard form

(cosθ + 3)(2cosθ - 1) = 0 ← in factored form

Equate each factor to zero and solve for θ

cosθ + 3 = 0

cosθ = - 3 ← not possible as - 1 ≤ cosθ  ≤ 1

2cosθ - 1 = 0

cosθ = \(\frac{1}{2}\) , so

θ = \(cos^{-1}\) (\(\frac{1}{2}\) ) = \(\frac{\pi }{3}\) ( or 60° )

The magazine would cost $33.93 to print a 1¾ inch ad in the "Good Ole Times" magazine.

The cost of a classified ad in the "Good Ole Times" magazine is determined by its size in column inches, with a cost of $43.50 per column inch. To determine how much the magazine would charge to print a 1¾ inch ad, we need to calculate the size of ad in column inches and then multiply that by the cost per column inch.

One way to convert 1¾ inches to column inches is to convert the fractional part (¾) to a decimal by dividing it by 4, which is the number of quarters in an inch. This gives us:

1¾ inches = 1 + ¾ inches = 1 + 0.75 inches = 1.75 inches

To express this measurement in column inches, we divide by the width of a column, which is not given in the problem. Assuming a typical newspaper column width of 2.25 inches, we get:

1.75 inches ÷ 2.25 inches per column = 0.7778 column inches

Rounding this to two decimal places, we get:

0.78 column inches

Now we can calculate the cost of the ad as follows:

Cost = Size in column inches × Cost per column inch

Cost = 0.78 column inches × $43.50 per column inch

Cost = $33.93

Therefore, the magazine would charge $33.93 to print a 1¾ inch ad.

For A₁ to have integer entries, the determinant of A must be an integer, and every entry in the first row of A must divide the determinant.

For matrix A to have integer entries, the determinant of A must be an integer. The determinant is a scalar value associated with a square matrix and is calculated using the entries of the matrix. It represents certain properties of the matrix, such as invertibility.

In the case of matrix A, if the determinant is an integer, it implies that the matrix is invertible and its inverse also has integer entries. This means that A can be row-reduced to the identity matrix using integer operations.

Additionally, for matrix A₁ (the first row of A) to have integer entries, the determinant of A must be divisible by every entry in the first row of A. If any entry in the first row is not a divisor of the determinant, the resulting row may contain non-integer elements.

The scale factor for the given dilation transformation is 1/3

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size.

Given that, a triangle ABC is being dilated to form a new triangle A'B'C'

We are asked to the scale factor,

The length of sides of triangle ABC is 6 units

And, length of sides of triangle A'B'C' is 2 units,

Since, the figure id shrinking, therefore, the dilation is a reduction, and scale factor must be less than 1,

Scale factor = 2/6

= 1/3

Hence, the scale factor for the given dilation transformation is 1/3

Given:

Lamont has purchased 20 trading cards.

He wants to have at least 50 trading cards.

To find:

The inequality for the number of trading cards Lamont needs and solve it.

Solution:

Let x be the number of trading cards Lamont needs.

He has 20 trading cards. So,

Total cards = x + 20

It is given that, he wants to have at least 50 trading cards. It means, total card must be greater than or equal to 50.

\(x+20\geq 50\)

Subtract 20 from both sides.

\(x+20-20\geq 50-20\)

\(x\geq 30\)

Therefore, the required inequality is \(x+20\geq 50\) and solution is \(x\geq 30\).

The number of trading cards that Lamont needs will be at least 30 trading cards.

From the information given, we are informed that Lamont has purchased 20 trading cards and wants to have at least 50 trading cards.

Therefore, the number that will be needed more will be:

= 50 - 20 = 30

Therefore, he'll need at least 30 more cards.

Answer:

\(k=-\frac{2}{5}\)

Step-by-step explanation:

\(k=-\frac{8}{20}=-\frac{4(2)}{4(5)}=-\frac{2}{5}\)

Answer: y = -32 and -(2/5)

Step-by-step explanation:

Let z equal to the difference,

x - z = -4

20 - z = -4

20 + 4 = z

z = 24

y - z

= -8 - 24

= -32

Therefore y = -32

For the second part of the question

-8 = k(20)

-8 = k * 20

-8/20 = k <-- Divide both sides by 20

Therefore k = -(8/20) = -(2/5)
