Answer:

p = 22/5

Step-by-step explanation:

50p+5=225

Subtract 5 from each side

50p+5-5=225-5

50p = 220

Divide by 50

50p/50 = 220/50

p = 22/5

Answer:

50p+5=225

(50p+5) + (-5) =225 + (-5)

50p + 5 - 5 = 225 - 5

50p = 220

2.(-2,5)

Step-by-step explanation:

y=2x+1

2x-3y =21

Take the first equation and substitute into the second

2x-3(2x+1) =21

Distribute

2x -6x-3 = 21

Combine like terms

-4x -3 = 21

Add 3 to each side

-4x-3+3 =21+3

-4x = 24

Divide by -4

-4x/4 = 24/-4

x = -6

Then find y

y = 2x+1 = 2(-6) +1 =-12+1 = -11

Elimination for problem 2

2x+3y=11 4x-3y=-23

Add the two equations together to eliminate y

2x+3y=11

4x-3y=-23

-----------------

6x = -12

Divide by 6

6x/6 = -12/6

x = -2

Multiply the first equation by -2

-4x+-6y=-22

4x-3y=-23

-----------------

 -9y = -45

Divide by -9

-9y/-9 = -45/-9

y = 5

Step-by-step Explanation:

If the average pain score after hypnotism is lower than the average pain score before hypnotism, it indicates that hypnotism is effective in reducing pain, on average.

To determine if the sensory measurements, on average, are lower after hypnotism, we need to analyze the data from the study. The table showing the results for randomly selected subjects can be used to calculate the mean scores for the group before and after hypnotism. If the mean score is lower after hypnotism, then we can conclude that hypnotism is effective in reducing pain. However, we need to ensure that the sample size is large enough and that the study was conducted properly to minimize any potential biases or confounding factors. Therefore, further investigation may be required before making any conclusive statements about the effectiveness of hypnotism in reducing pain. To investigate the effectiveness of hypnotism in reducing pain, we need to compare the sensory measurements before and after hypnotism. Here's a step-by-step explanation:
1. Obtain the data of randomly selected subjects' pain scores before and after hypnotism.
2. Calculate the average pain score for the subjects before hypnotism.
3. Calculate the average pain score for the subjects after hypnotism.
4. Compare the average pain scores before and after hypnotism.

Answer:

Step-by-step explanation:

True.The given statement "If the alternative hypothesis includes the symbol <, the rejection region is in the upper tail" is true.

If the alternative hypothesis involves less than the symbol <, the rejection region would be in the upper tail.There are two possibilities for the alternative hypothesis, one is that it is two-sided (≠), and the other is that it is one-sided (< or >).

When the null hypothesis is true, a one-tailed test is more efficient than a two-tailed test because it is more likely to detect a real difference. A one-tailed test is appropriate when we want to test whether a parameter is greater than or less than a certain value.

The hypothesis test's alternative hypothesis is a statement that is accepted if the null hypothesis is rejected. A one-tailed test is a hypothesis test in which the region of rejection is located on only one side of the distribution.As a result, if the alternative hypothesis includes the symbol <, the rejection region is in the upper tail. The alternative hypothesis is typically denoted by H1, while the null hypothesis is denoted by H0.

It is necessary to specify the rejection region in the alternative hypothesis, which can be one-tailed (one-sided) or two-tailed (two-sided).If the alternative hypothesis involves less than the symbol <, the rejection region would be in the upper tail. The null hypothesis and the alternative hypothesis must be mutually exclusive and collectively exhaustive; that is, they must cover all possibilities. We cannot test both hypotheses at the same time because they are contradictory; instead, we must determine which hypothesis is more likely to be true based on the sample data.The null hypothesis assumes that there is no distinction between the population parameters and the sample statistics. The alternate hypothesis assumes that the sample statistics vary from the population parameters.

As a result, the alternative hypothesis can be written as Ha: µ < µ0 or Ha: µ > µ0 if the rejection region is one-sided.

Answer:

The new expression is \(p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}\).

Step-by-step explanation:

A polynomial is a sum of algebraic monomials such that:

\(p = \Sigma_{i=0}^{n} c_{i}\cdot x^{i}\)

Where \(n\) is the degree of the polynomial and \(c_{i}\) is the i-th coefficient of the polynomial. A 22nd degree polynomial has \(n = 22\), so that given polynomial must added by a monomial with grade 22. Thus:

If \(p = 5\cdot x^{2} + 11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}\) and \(q = 12\cdot x^{22}\), then we have:

\(p' = p+q\)

\(p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}\)

The new expression is \(p' = 5\cdot x^{2}+11\cdot x^{4}-9\cdot x^{15}+14\cdot x^{19}+12\cdot x^{22}\).

Answer:

DE ≈ 40

Step-by-step explanation:

Using the Sine rule in Δ DEF

∠ D = 180° - (58 + 87)° ← sum of angles in a triangle

∠ D = 180° - 145° = 35° , then

\(\frac{DE}{sin87}\) = \(\frac{EF}{sin35}\) = \(\frac{23}{sin35}\) ( cross- multiply )

DE × sin35° = 23 × sin87° ( divide both sides by sin35° )

DE = \(\frac{23sin87}{sin35}\) ≈ 40 units ( to the nearest whole number )

The pair of hypotheses used to test if the mean of the first population is smaller than the mean of the second population, using independent random sampling, is H0: µ1-µ2 ≥ 0 and HA: µ1-µ2 < 0.

The given pair of hypotheses represents a one-tailed test where we are interested in determining if the mean of the first population (µ1) is smaller than the mean of the second population (µ2).

The null hypothesis (H0) states that the difference between the means, represented by (µ1-µ2), is greater than or equal to zero. This means that there is no significant difference between the means or that the mean of the first population is equal to or greater than the mean of the second population.

The alternative hypothesis (HA) states that the difference between the means, represented by (µ1-µ2), is less than zero. This suggests that there is a significant difference between the means and specifically indicates that the mean of the first population is smaller than the mean of the second population.

By conducting a statistical test, such as a t-test or z-test, and analyzing the results, we can evaluate the evidence and make an inference regarding the relationship between the means of the two populations based on the given pair of hypotheses.

Answer:

The probability that exactly five students out of 12 contract a stomach virus while visiting Mexico is approximately 0.2707 or 27.07%.

Step-by-step explanation:

To find the probability that exactly five students out of 12 contract a stomach virus while visiting Mexico, we can use the binomial probability formula.

The formula is P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

where X is the number of students who contract the virus, k is the specific number we're interested in (in this case, 5), n is the total number of students (12), p is the probability of one student contracting the virus (0.23), and "n choose k" is the binomial coefficient - the number of ways to choose k objects out of n, which can be calculated using the formula n!/(k!(n-k)!).

Using these values, we get:

P(X=5) = (12 choose 5) * 0.23^5 * (1-0.23)^(12-5)

= 792 * 0.0009765625 * 0.3457171406

= 0.2706918748

Therefore, the probability that exactly five students out of 12 contract a stomach virus while visiting Mexico is approximately 0.2707 or 27.07%.

The distance of the jot air balloon to ground is 21.62 ft.

Here, we have,

In triangle ACB:

tan36° = x/y

x  = y tan36°

In triangle ADB:

tan25° = x/y + 12

x  = y+12 * tan25°

Therefore equating both equations gives:

y tan36°  =  y+12 * tan25°

y tan36°  =  y tan25° + 12tan25°

so, we get,

y = 21.50 ft

Therefore x = 21.50*tan(36) = 15.62 ft

The distance of the jot air balloon to ground = 15.62 + 6 = 21.62 ft

Hence, The distance of the jot air balloon to ground is 21.62 ft.

The number of tiles that will fit along the edge of the square mosaic is 28 tiles.

The concept used here is finding the square root of an area to determine the length of a side of a square and then using simple division to determine the number of tiles that will fit along the edge of the square. This involves using the formulas for finding the area of a square and the perimeter of a square.

To determine the number of 2 in x 2 in tiles that will fit along the edge of a square mosaic, you need to determine the length of one side of the square mosaic. You can do this by finding the square root of the total area:

sqrt(196) = 14

So one side of the square mosaic is 14 inches. The perimeter of the square is 4 * 14 = 56 inches.

Since each tile is 2 inches wide, the number of tiles that will fit along the edge of the square mosaic is 56 / 2 = 28 tiles.

Thus, the number of tiles that will fit along the edge of the square mosaic is 56 / 2 = 28 tiles.

Required area of the composite figure is 69 cm²

What is area of a composite shape?

the area covered by any composite shape. A composite shape is a shape in which some polygons are put together to form the required shape is called the area of composite shapes . These figures can consist of combinations of triangles, rectangles, squares etc. To determine the area of composite shapes, divide the composite shape into basic shapes such as square, rectangle,triangle, hexagon, etc.

Basically, a compound shape consists of basic shapes put together. This is also called a "composite" or "complex" shape. This mini-lesson explains the area of compound figures with solved examples and practice questions.

Here in this figure, we have two figures.

First one is rectangle and second one is triangle.

Length and breadth of the rectangle are 12 cm and 4 cm respectively.

So, area = Length × Breadth = 12 × 4 = 48 cm²

Again height of the triangle is (11-4) = 7 cm and base of the triangle is (12-6) = 6 cm.

So, area of the triangle = 1/2 × 7 × 6 = 3×7 = 21 cm²

Now if we add both area of rectangle and triangle then we will get area of the composite figure.

So, required area of the composite figure is ( 48+21) = 69 cm²

Therefore, option A is the correct option.

An angle is a measure of a turn or a rotation. It is usually measured in degrees, radians, or gradians. An angle is formed by two rays that share a common endpoint, called the vertex. Angles can be measured in a variety of ways, including the degree of rotation between the two rays, the ratio of the lengths of the sides of the angle, or the angle between two lines. An angle can also be used to describe the orientation of an object relative to another object or point.

There are 907,200 ways to arrange the letters of "hudsonicus" that begin with vowels or end with consonants.

The word "hudsonicus" has 10 letters, including 3 vowels (u, o, i) and 7 consonants (h, d, s, n, c). To find the number of ways to arrange the letters such that the word begins with a vowel or ends with a consonant, we can use the principle of inclusion-exclusion.

Let A be the set of arrangements that begin with a vowel, and let B be the set of arrangements that end with a consonant. We want to find the size of the set A ∪ B, which is the set of arrangements that satisfy either condition.

To find the size of A, we can fix the first letter to be a vowel (either "u", "o", or "i") and arrange the remaining 9 letters in any order. There are 3 choices for the first letter and 9!/(2!2!2!) ways to arrange the remaining letters (dividing by 2!2!2! to account for the repeated letters "d", "s", and "u"). Therefore, the size of A is 3 * 9!/(2!2!2!).

To find the size of B, we can fix the last letter to be a consonant (any letter except "u", "o", or "i") and arrange the remaining 9 letters in any order. There are 7 choices for the last letter and 9!/(2!2!2!) ways to arrange the remaining letters. Therefore, the size of B is 7 * 9!/(2!2!2!).

However, we have counted the arrangements that both begin with a vowel and end with a consonant twice, so we need to subtract the size of the set A ∩ B from the sum of the sizes of A and B. To find the size of A ∩ B, we can fix the first and last letters to satisfy both conditions and arrange the remaining 8 letters in any order. There are 3 choices for the first letter, 7 choices for the last letter, and 8!/(2!2!2!) ways to arrange the remaining letters. Therefore, the size of A ∩ B is 3 * 7 * 8!/(2!2!2!).

Using the principle of inclusion-exclusion, the number of ways to arrange the letters of "hudsonicus" such that the word begins with a vowel or ends with a consonant is:

|A ∪ B| = |A| + |B| - |A ∩ B|

= 3 * 9!/(2!2!2!) + 7 * 9!/(2!2!2!) - 3 * 7 * 8!/(2!2!2!)
