Step-by-step explanation:

Let the "certain number" be \(x\).

(\(*\) is a symbol for multiplication).

Create a few equations and expressions:

The sum of 12 and a certain number: \(12 + x\)

The product of 3 and the number: \(3 *x = 3x\)

The sum of 12 and a certain number is equal to the product of 3 and the number:

\(12 + x\) = \(3x\)

Solve!

12=3x-x

12=2x

x=6

Step-by-step explanation:

Line passing through AB is perpendicular. A pair of angles that are linear have an angle sum of 180 degrees. The lines are therefore shown to be perpendicular to one another because the angles are 90 degrees in size.

Two lines intersect to generate perpendicular lines, and the angle formed between the two lines must be 90 degrees (right angle).

Given,

Create another line perpendicular to AB passing through C on AB..

Line passing through AB is perpendicular.

Two lines are perpendicular if they cross at a point where a pair of linear congruent angles results. In a plane, a transversal is perpendicular to the other line if it is parallel to one of the two parallel lines.

A pair of angles that are linear have an angle sum of 180 degrees. The lines are therefore shown to be perpendicular to one another because the angles are 90 degrees in size. The linear pair perpendicular theorem is demonstrated by this.

The coordinates of the image of the triangle ABC after the dilation with center (0,0) and a scale factor of 1/2 are:

A' = (1/2 * x₁, 1/2 * y₁)

B' = (1/2 * x₂, 1/2 * y₂)

C' = (1/2 * x₃, 1/2 * y₃)

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

To find the image of triangle ABC after a dilation with center (0,0) and a scale factor of 1/2, we need to multiply the coordinates of each vertex by the scale factor.

Let's suppose that the coordinates of the vertices of the original triangle ABC are:

A = (x₁, y₁)

B = (x₂, y₂)

C = (x₃, y₃)

Then, the coordinates of the image of A, B, and C after the dilation are:

A' = (1/2 * x₁, 1/2 * y₁)

B' = (1/2 * x₂, 1/2 * y₂)

C' = (1/2 * x₃, 1/2 * y₃)

Therefore, the coordinates of the image of the triangle ABC after the dilation with center (0,0) and a scale factor of 1/2 are:

A' = (1/2 * x₁, 1/2 * y₁)

B' = (1/2 * x₂, 1/2 * y₂)

The probability that there will be less than two days between manufacturing production line outages is approximately 0.553, or 55.3%.

We need to make some assumptions in order to calculate the probability that the time intervals between manufacturing production line breakdowns will be shorter than two days. Assume that the intervals between breakdowns have an exponential distribution with a mean of 3.5 days (1/2 times per week).

The probability that an interarrival time is fewer than two days can be calculated using the exponential distribution formula as follows:

P(X < 2) = 1 - e(-2/3.5)

where "X" stands for the duration in between breakdowns.

When we condense the expression, we get:

P(X < 2) = 0.553

Therefore, The probability that there will be less than two days between manufacturing production line outages is approximately 0.553, or 55.3%.

There are 792 poker hands consisting of all face cards.

To determine the number of poker hands consisting of all face cards, we need to consider the number of ways we can select 5 face cards from the 12 available face cards.

Since we are selecting a specific number of items from a larger set without considering the order, we can use combinations to calculate the number of poker hands.

The number of combinations of selecting k items from a set of n items is given by the formula:

C(n, k) = n! / (k!(n-k)!)

In this case, we want to select 5 face cards from the set of 12 face cards, so we can calculate:

C(12, 5) = 12! / (5!(12-5)!)

C(12, 5) = 12! / (5! * 7!)

Calculating the factorial terms:

12! = 12 * 11 * 10 * 9 * 8 * 7!

5! = 5 * 4 * 3 * 2 * 1

7! = 7 * 6 * 5 * 4 * 3 * 2 * 1

Plugging in the values:

C(12, 5) = (12 * 11 * 10 * 9 * 8 * 7!) / (5 * 4 * 3 * 2 * 1 * 7!)

Simplifying the expression:

C(12, 5) = (12 * 11 * 10 * 9 * 8) / (5 * 4 * 3 * 2 * 1)

C(12, 5) = 792

Therefore, there are 792 poker hands consisting of all face cards.

Answer: The number of first-year residents she must survey to be 95% confident= 263

Step-by-step explanation:

When population standard deviation (\(\sigma\))  is known and margin of error(E) is given, then the minimum sample size (n) is given by :-

\(n=(\dfrac{z^*\sigma}{E})^2\), z* = Two-tailed critical value for the given confidence interval.

For 95% confidence level , z* = 1.96

As, \(\sigma\) = 8.265, E = 1

So, \(n= (\dfrac{1.96\times8.265}{1})^2 =(16.1994)^2\\\\= 262.42056036\approx263\ \ \ [\text{Rounded to the next integer}]\)

The sum of the three even positive integers is 18.

A whole number that is greater than zero is what is meant by the term "positive integer." All counting numbers are included in the set of positive integers (that is, the natural numbers).

A set (collection of objects) whose components are numbers is known as a number set. All whole numbers on the number line to the right of zero are included in the set of positive integers. The Z, the superscript asterisk (*), and the subscript plus sign (+) all stand for the set of all positive numbers.

The  Z was chosen because it derives from the German word for numbers and signifies integers in general (positive, negative, and zero) (Zahlen). The plus sign indicates that negative numbers are eliminated, while the asterisk indicates that zero is excluded from the set of integers.

here it is given in the question that,

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.

When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.

The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.

This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.

The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit. This may enable more competitive pricing on the market or result in larger profit margins.

Second, raising returns to scale can result in better operational effectiveness and resource utilisation. As the company grows in size, it will be able to use resources more wisely and profit from production volume-related synergies.market prices that are competitive.

The domain and range of the function f(x) = 4/x-3 are ( -∞,3 ) U ( 3,∞ ) and ( -∞,0 ) U ( 8,∞ ) respectively.

The domain is simplify the portion of the x-axis that a graph covers while range is the portion of the y-axis that the graph covers.

Given the function in the question;

f(x) = 4/x-3

To find the domain, set the denominator in the function equal to zero and find where the expression is undefined.

x - 3 = 0

Add 3 to both sides

x - 3 + 3 = 0 + 3

x = 0 + 3

x = 3

Hence, the domain is all values of x that makes the expression defined.
