Step-by-step explanation:

The expression 18 + π is "irrational."

The expression 18 + π is a sum of a rational number (18) and an irrational number (π).

To understand why the sum of a rational number and an irrational number is always irrational, we need to consider the properties of rational and irrational numbers.

A rational number can be expressed as the ratio of two integers, such as 1/2, 3/4, or -5/6.

These numbers can be written as fractions or terminating decimals.

On the other hand, an irrational number cannot be expressed as the ratio of two integers.

Irrational numbers include π (pi), √2 (square root of 2), or e (Euler's number).

These numbers cannot be represented as fractions or terminating decimals and have non-repeating, non-terminating decimal representations.

We add a rational number and an irrational number, the resulting sum cannot be expressed as a fraction or terminating decimal.

It will have a decimal representation that continues infinitely without repeating, just like the irrational number involved in the sum.

The Z scores a way to standardize and compare data, as well as to identify outliers.

In simple terms, Z bases give information about how far a data point is from the means of the data set in standard deviation units. The original non-standardized heights, on the other hand, did not guarantee this information.

Z scores are used to standardize data and are useful when comparing two or more different data sets. By converting the original data to Z scores, we can compare data that is on different scales or has different units.

For example, suppose we have two data sets: one with heights measured in inches and the other with weights measured in pounds. We cannot compare these data sets directly as they are at different scales. However, by converting them to Z scores, we can compare them on the same scale.

In addition, the obtained Z's provided a way to identify outliers in the data set. Outliers are data points that are unusually far from the means of the data set. Z scores greater than 3 or less than -3 are generally considered outliers.

In general, the obtained bases are a way to standardize and compare data, as well as to identify outliers.

The coordinates of the image are given as:

The dilation rule is given as:

(x,y) -> 4(x,y)

So, we have:

(-8,4) = 4 * g

Divide both sides by 4

g = (-2,1)

The area under the standard normal curve between z=-2.95 and z=2.61 is approximately 0.9942.

What is curve?

A curve is a geometrical object that is made up of points that are continuous and connected to form a line or a path. It can be defined mathematically by an equation or parametrically by a set of equations that describe the x and y coordinates of points on the curve as a function of a parameter such as time or distance along the curve.

Using a standard normal distribution table, we can find the area under the curve between z=-2.95 and z=2.61 as follows:

Area = Phi(2.61) - Phi(-2.95)

Where Phi(z) represents the cumulative distribution function of the standard normal distribution.

From the standard normal distribution table, we find:

Phi(2.61) = 0.9959

Phi(-2.95) = 0.0017

Therefore, the area under the curve between z=-2.95 and z=2.61 is:

Area = 0.9959 - 0.0017 = 0.9942

Rounding to four decimal places, we get:

Area ≈ 0.9942

Therefore, the area under the standard normal curve between z=-2.95 and z=2.61 is approximately 0.9942.

The work done in stretching the spring from its natural length to 0.9 feet beyond its natural length is 3 foot-pounds.

This can be calculated using the equation W = F * d, where W is the work done, F is the force applied, and d is the distance the spring is stretched. In this case, F is 6 pounds and d is 0.5 feet (0.9 feet - 0.4 feet). Thus, W = 6 * 0.5 = 3 foot-pounds.

Force is a concept in physics that describes the influence that can change the motion of an object. Work done is the amount of energy transferred to or from an object when a force acts on it and causes it to move through a distance.

Multiply the second equation by −2 to get −4x − 12y = −48.

Step-by-step explanation:

Given:

4x + y = 4 (1)

2x + 6y = 24 (2)

Multiply the second equation by −2 to get −4x − 12y = −48.

4x + y = 4 (1)

−4x − 12y = −48 (3)

Variable x can be eliminated by adding the equations

4x + (-4x) + y + (-12y) = 4 + (-48)

4x - 4x + y - 12y = 4 - 48

0 - 11y = -44

-11y = -44

Divide both sides by -11

y = -44/-11

625 numbers can be formed using the digits 0, 2, 5, 7, and 8, with repetition allowed.

The number of four-digit numbers that can be formed from the digits 0, 2, 5, 7, and 8 with repetition allowed can be calculated by considering the number of choices for each digit position. Since repetition is allowed, each digit can be selected from the given set of digits independently for each position.

For the thousands place, any of the five digits can be chosen, so there are 5 choices. Similarly, for the hundreds, tens, and units places, there are also 5 choices each. Therefore, the total number of four-digit numbers that can be formed is calculated by multiplying the number of choices for each position: 5 × 5 × 5 × 5 = 625.

Hence, 625 numbers can be formed using the digits 0, 2, 5, 7, and 8, with repetition allowed.

The minimum number of integers that must be odd, then, is (A) 1.

So, it is conceivable for the initial two integers to both be even, as in the case of 10 + 16 = 26.

The next two numbers, however, when added together, result in an odd 15 increase, thus one of them must be odd and the other must be even. For instance, 3 + 12 equals 15.

Last but not least, the following two integers add up to 16, which is even, therefore we can have both be even: for instance, 2 + 14 = 16.

The number of months for which the company made no profit is 18 months.

Generally speaking, a product's profit is defined as the sum received from sales, which should exceed the product's cost price. It is the gain from any type of commercial activity. In other words, if a product's selling price (SP) is higher than its cost price (CP), there has been a gain or profit. It explains the monetary gain realised if the revenue from the company activity is greater than the costs, such as taxes and expenses, involved in maintaining the business activity.

The cost function is given as: C(x) = 17- 8x - 2x²

The revenue function is given as: R(x) = 5 - 3x

Profit = Revenue - Cost

For no profit the equation becomes:

5 - 3x - 17 + 8x + 2x² = 0

2x² + 5x - 12 = 0

2x² + 8x - 3x - 12 = 0

2x(x + 4) - 3(x + 4) = 0

2x - 3 = 0 and x + 4 = 0

x = 3/2 and x = -4

Since, month cannot be a negative quantity we have x = 3/2.

That is 3/2 (12) = 18 months.

The number of months for which the company made no profit is 18 months.

Answer:

23: 21\(\frac{23}{55}\)  25: 1\(\frac{44}{45}\)

Step-by-step explanation:

Question 23:

1) add the whole numbers together: 15+5=20

2)To add fractions, both need to have the same denominator. Find a number that is a multiple of both denominators (in this case 55)

\(\frac{9}{11}\) → \(\frac{45}{55}\) (multiply the numerator and denominator by 5)

\(\frac{3}{5}\) → \(\frac{33}{55}\) (multiply the numerator and denominator by 11)

3) add the fractions together

\(\frac{45}{55}\) + \(\frac{33}{55}\) = \(\frac{78}{55}\) (add the numerators)

4) Turn the improper fraction into a mixed number

Divide 78 by 55. You'll get a whole number and a remainder. The remainder is the new numerator: In this case 55 enters 78 once with a remainder of 23. Therefore:

1\(\frac{23}{55}\)

5) Add the whole numbers together to get the final answer:

20+1= 21

Answer: 21\(\frac{23}{55}\)
