Step-by-step explanation:

The solution is, the probability is, 0.5532.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given that,

P( 31<X<35.7)

P(X>31)= P(Z>(31-μ)/σ)

           = P(Z>(31-34.6)/2.8)

           = P(Z> -1.2857)

P(X<35.7)= P(Z<(35.7-μ)/σ)

              = P(Z<(35.7-34.6)/2.8)

              =P(Z< 0.392857)

From z-distribution table

P(Z< -1.29)= 0.09853

p(Z< 0.39) = 0.65173

P( 31<X<35.7)= P(Z<0.39)- P(Z<-1.29)

                     = 0.65173- 0.09853

                     =0.5532

Hence, The solution is, the probability is, 0.5532.

The Morse Fall Scale (MFS) is a standardized tool used to assess a patient's risk of falling. It is used by healthcare professionals in a variety of clinical settings, including hospitals, long-term care facilities, and home care.

The MFS was first developed in 1987 by Dr. Morse and her colleagues as a way to identify patients at high risk for falls and to implement fall prevention measures. The MFS is a quick and simple tool that assesses six different risk factors for falls. These risk factors include history of falling, secondary diagnosis, ambulatory aids, intravenous therapy, gait, and mental status. The MFS assigns points to each risk factor based on the severity of the risk, with a maximum score of 125. Patients who score higher on the MFS are considered to be at higher risk for falls and require more intensive fall prevention interventions. The MFS is useful for healthcare professionals in identifying patients at risk for falls and in developing an individualized fall prevention plan. The MFS is also useful in measuring the effectiveness of fall prevention interventions by allowing healthcare professionals to track a patient's progress over time. However, it is important to note that the MFS is only one tool in a comprehensive fall prevention program and should not be used in isolation.

In summary, the Morse Fall Scale is a standardized tool used to assess a patient's risk of falling. It is a simple and quick tool that assesses six different risk factors and assigns points based on the severity of the risk. The MFS is useful in identifying patients at risk for falls and in developing an individualized fall prevention plan.

The standard deviation of the given data is  8.

Option B is the correct answer.

To calculate the standard deviation of the given data, we can use the following formula:

σ = √ [Σ(xi - μ)² / N

where σ is the standard deviation, xi is each data point, μ is the mean of the data, and N is the total number of data points.

We have,

The mean of the data:

μ = (24 + 28 + 32 + 36 + 40 + 44 + 48) / 7

  = 36

Now,

We can calculate the sum of squared differences from the mean.

Σ(xi - μ)²

= (24 - 36)² + (28 - 36)² + (32 - 36)² + (36 - 36)² + (40 - 36)² + (44 - 36)²

+ (48 - 36)²

= 144 + 64 + 16 + 0 + 16 + 64 + 144

= 448

And,

We can substitute these values into the formula for the standard deviation.

So,

σ = √ [Σ(xi - μ)² / N]

= √[448 / 7]

= 8.13

= 8

Therefore,

The standard deviation of the given data is  8.

Answer:

The drama club receives $9 for each ticket they sell.

Step-by-step explanation:

The total amount of money the drama club receives from selling 108 tickets is the difference between the total amount collected and the amount donated to the school.

Total amount collected = 108x + 972

Amount donated to the school = 108x

Amount received by the drama club = (108x + 972) - 108x = 972

Therefore, the drama club receives a fixed amount of $972 for selling 108 tickets.

To find how much money the drama club receives for each ticket sold, divide the total amount received by the number of tickets sold:

972/108 = $9

Therefore, the drama club receives $9 for each ticket they sell.

vertical angle theorem

angle addition postulate

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

The evidence in the proof that supports the statement that m/AOW = 45° is:

Statement 3: ZZOB ZXOA. This means that ZOB and ZOA are vertical angles, which means they are congruent.

Statement 4: m/XOA = 45°. This is the measure of ZOA, which is congruent to ZOB.

Statement 7: m/XOA + m/AOW = m/XOW. This is the angle addition postulate, which states that the sum of the measures of the angles in a triangle is 180°.

So, combining these pieces of evidence, we have:

m/XOA = 45° and m/XOA + m/AOW = m/XOW,

therefore m/AOW = m/XOW - m/XOA

                              = 90° - 45°

                              = 45°.

The zeroes of the polynomial  f(x) = 2x³ - 11x² - 20x - 7 are - 1, - 1/2, and 7.

We know that if x = a is one of the roots of a given polynomial x - a = 0 is a factor of the given polynomial.

To confirm if x - a = 0 is a factor of a polynomial we replace f(x) with f(a) and if the remainder is zero then it is confirmed that x - a = 0 is a factor.

Given, A cubic polynomial f(x) = 2x³ - 11x² - 20x - 7.

Now, If f(7) = 0 then (x - 7) is a factor of the polynomial f(x).

Therefore, f(x) = (x - 7)(2x² + 3x + 1).

Now, 2x² + 3x + 1 = 0.

2x² + 2x + x + 1 = 0.

2x(x + 1) + 1(x + 1) = 0.

(x + 1)(2x + 1) = 0.

45 pieces of 4 inch can the dressmaker cut from 5 of these rolls of ribbon.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

1 roll = 3 feet of ribbon

So, 5 rolls = 5 x 3 = 15 feet of ribbon

and, 1 foot = 12 inches

Then, 15 feet = 15 x 12 = 180 inches

The dressmaker has 180 inches of ribbon in total.

Answer: In summary, all integers can be classified as either positive, negative, or zero.

Step-by-step explanation:

There are three types of integers: positive integers, negative integers, and zero.

Positive integers: Positive integers are numbers greater than zero, such as 1, 2, 3, 4, and so on.

Negative integers: Negative integers are numbers less than zero, such as -1, -2, -3, -4, and so on.

Zero: Zero is an integer that is neither positive nor negative. It is the only integer that is neither positive nor negative, and it is often referred to as the "origin" on a number line.

In summary, all integers can be classified as either positive, negative, or zero.

Answer: The three types of integers are Zero (Neutral Integers), Negative Integers, and Positive Integers.

Step-by-step explanation:

Negative Integers are the ones that has a value less than zero, examples of these are -7, -8, -9.

Positive integers, on the other hand. Are the ones that has a value more than zero, examples of these are 10, 11, 12, 13.

Note: The key difference between Negative Integers and Positive Integers is that a negative integer has a "-" sign, while a positive integer does not.

Zero are the neutral integers which means that it's the integer that's in the middle of the positive and negative integers, it has neither a positive sign or a negative sign.

Another note: Integers do not include fractions or decimals, only whole numbers.

4 ounces is equal to 0.25 pounds. Since 1 pound is equal to 16 ounces, to convert ounces to pounds, you need to divide the number of ounces by 16. So, 4 ounces divided by 16 equals 0.25 pounds.

One pound is equivalent to 16 ounces. To convert 4 ounces to pounds, you need to divide 4 by 16. This gives the result of 0.25 pounds, since 4 ounces is one-quarter of a pound. The conversion factor between ounces and pounds is useful when working with small weights, as ounces are commonly used to express small quantities of weight, while pounds are used for larger quantities. Knowing the conversion factor can help in many situations, such as when cooking, measuring ingredients or mailing a package, where it may be necessary to convert between different units of weight.

The angle is formed by a secant and tangent line is GSE.

NS is a secant, whereas SE is a tangent line. Thus, they combine to form the angle GSE.

Tangents to circles are lines that cross the circle at a single point. Point of tangency refers to the location where a tangent and a circle converge. The circle's radius, where the tangent crosses it, is perpendicular to the tangent. Any curved form can be considered a tangent. Tangent has an equation since it is a line. A line that touches a circle just once is said to be tangent to it. A point to circle can only have one tangent. The intersection of the tangent and the circle is known as the point of tangency.

The required the average speed must be at least 52.5 mph to travel 420 miles in 8 hours.

A difference between two values indicates whether one is smaller, larger, or simply not equal to the other. A B indicates that a and b are not equal. When a b, an is said to be less than b. A > B indicates that an is superior to b. These two constitute tight inequity.

Let the average speed of the trip "x" in miles per hour. To find out what the average speed must be, we need to write an inequality based on the given information and then solve it.

The formula for distance, speed, and time is:

distance = speed * time

So, the distance traveled can be written as:

distance = x * 8 hours

And the inequality based on the given information that the distance must be at least 420 miles is:

x * 8 ≥ 420

To solve for x, we need to divide both sides of the inequality by 8:

x ≥ 420 / 8

x ≥ 52.5

So, the average speed must be at least 52.5 mph to travel 420 miles in 8 hours.

Answer:

Step-by-step explanation:

The sum of the interior angles in a polygon can be calculated using the following formula:

(n - 2) * 180 degrees

where n is the number of sides in the polygon.

To understand why this formula works, let's consider a single interior angle in the polygon. Each interior angle is split into two equal angles that form a straight line. The sum of these two angles is 180 degrees. Now, if we look at all the interior angles in the polygon, we can see that they are divided into (n - 2) pairs of angles that form straight lines. This means that the sum of all the interior angles in the polygon is (n - 2) * 180 degrees.

For a hexagon, which has 6 sides, we can plug in n = 6:

(6 - 2) * 180 = 4 * 180 = 720 degrees

So, the sum of the interior angles in a hexagon is 720 degrees.

  b. Square the number of the next term, n

Step-by-step explanation:

You want to know the pattern of the sequence 1, 4, 9, 16, 25, ... and why it tells you the next number is 36.

Usually we look for a common difference or a common ratio when we're trying to identify a sequence as arithmetic or exponential. This sequence has neither, as the differences are 3, 5, 7, 9, and the ratios are 4, 9/4, 25/16.

Neither of these are constant sequences. However, we do notice that the sequence of differences has a common difference of 2. The fact that "second differences" are common (all the same) means the sequence can be described by a second-degree polynomial.

Looking at the sequence values, we see they are ...

  1 = 1², 4 = 2², 9 = 3², 16 = 4², 25 = 5²

so we expect the 6th term to be the square of 6, 6² = 36. This is in line with the predicted next number.

The pattern is ...
