Determine the number of proper subsets contained in P if P={x| x is an odd, positive integer and x < 20}.

There is no whole number by which you can multiply or divide 16087 to make it a perfect square.

To determine by which number you should multiply or divide 16087 to make it a perfect square, we can analyze its prime factorization. The prime factorization of 16087 is 13 × 1237.

In order to make 16087 a perfect square, we need each prime factor to have an even exponent. However, when we examine the prime factors of 16087, we find that both 13 and 1237 have an exponent of 1.

To make the exponents even, we need to multiply or divide 16087 by additional prime factors and their respective exponents. However, since 16087 is a product of two prime numbers (13 and 1237), we cannot introduce any additional prime factors to make the exponents even.

A perfect square is a number that can be expressed as the product of two equal factors. In the case of 16087, it cannot be transformed into a perfect square by multiplying or dividing by any whole number. The prime factors 13 and 1237 remain with an exponent of 1 each, indicating that there is no integer that can be applied to make them equal and convert 16087 into a perfect square.

Therefore, there is no whole number by which you can multiply or divide 16087 to make it a perfect square.

The blue shaded portion on the top left side is described as forming lines pass through (6, 0) and (0, -2) and intersect at (0, -2).

This corresponds to the shaded portion W. D.

To graph the system of inequalities y ≥ 1/3x - 2 and y ≤ -4x - 2, we will plot the lines corresponding to each inequality and shade the region that satisfies both inequalities.

First, let's graph the line y = 1/3x - 2.

We can find two points on this line and connect them with a straight line:

Using (6, 0):

y = 1/3(6) - 2

y = 2 - 2

y = 0

So we have the point (6, 0).

Using (0, -2):

y = 1/3(0) - 2

y = -2

So we have the point (0, -2).

Plotting these two points and drawing a line through them, we get a line labeled as Line 1.

Next, let's graph the line y = -4x - 2 using the same process:

Using (0.5, 0):

0 = -4(0.5) - 2

0 = -2 - 2

0 = -4

So we have the point (0.5, 0).

Using (0, -2):

-2 = -4(0) - 2

-2 = -2

So we have the point (0, -2).

Plotting these two points and drawing a line through them, we get a line labeled as Line 2.

Now, we need to shade the region that satisfies both inequalities.

The shaded region will be the region where Line 1 is above Line 2.

Based on the given descriptions of the shaded portions W, X, Y and Z we can determine the correct option.

The blue shaded portion on the top left side is described as forming when lines pass through (0.5, 0) and (0, -2) and intersect at (0, -2).

This corresponds to the shaded portion X.

The blue shaded portion on the left side is described as forming when lines pass through (0.5, 0) and (0, -2) and intersect at (0, -2).

This corresponds to the shaded portion Y.

The blue shaded portion on the bottom left side is described as forming when lines pass through (6, 0) and (0, -2) and intersect at (0, -2).

This corresponds to the shaded portion Z.

Answer:

The upper 20% of the weighs are weights of at least X, which is \(X = 0.84\sigma + \mu\), in which \(\sigma\) is the standard deviation of all weights and \(\mu\) is the mean.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Upper 20% of weights:

The upper 20% of the weighs are weighs of at least X, which is found when Z has a p-value of 0.8. So X when Z = 0.84. Then

\(Z = \frac{X - \mu}{\sigma}\)

\(0.84 = \frac{X - \mu}{\sigma}\)

\(X = 0.84\sigma + \mu\)

The upper 20% of the weighs are weights of at least X, which is \(X = 0.84\sigma + \mu\), in which \(\sigma\) is the standard deviation of all weights and \(\mu\) is the mean.

Answer:

a. ordinal

Step-by-step explanation:

A level of measurement refers to a classification which is used to illustrate the attributes of the values assigned to variables. Basically, there are four (4) levels of measurement for a variable and these are;

1. Ratio: data can be arranged in an ordering scheme and subtracting its differences is meaningful with respect to the value of true zero. Examples are height, price, weight, distance etc.

2. Nominal: is characterized by data that are non-numerical, comprises of categories, labels or names and can't be arranged in an ordering scheme.

3. Interval: data can be arranged in an ordering scheme and subtracting its differences is meaningful. Examples are year, temperature, time etc.

4. Ordinal: data can be arranged in an ordering scheme but subtracting its differences is meaningless or impossible. Examples are happy, sad etc.

Therefore, the data are at the ordinal level of measurement because mood levels were represented as 0 for bad, 1 for OK, and 2 for good.

However, what is wrong with these given calculation; "average​ (mean) of the 637 mood levels is 0.9." is that the data presented in the question cannot be used to find an average (mean) because the various mood levels were not stated or given, which is a prerequisite for calculating the average (mean) of a population.

Answer:

Length of all 3 sides: 7, 7, and 9

Length of the two sides that have the same length: 7

Step-by-step explanation:

Let the two sides with equal lengths have a length of \(x\). We can write the third side as \(2x-5\).

The perimeter of a polygon is equal to the sum of all its sides. Since the perimeter of the triangle is 23 meters, we have the following equation:

\(x+x+2x-5=23\)

Combine like terms:

\(4x-5=23\)

Add 5 to both sides:

\(4x=28\)

Divide both sides by 4:

\(x=\frac{28}{4}=\boxed{7}\)

Therefore, the three sides of the triangle are 7, 7, and 9 and the length of the two sides that have the same length is 7.

The value of x in the parallelogram is 112°.

In a parallelogram, adjacent angles are always supplementary. This means that the sum of two adjacent angles in a parallelogram is always 180 degrees.

To understand this concept, let's consider a parallelogram ABCD. The opposite sides of a parallelogram are parallel and equal in length, and the opposite angles are congruent. Adjacent angles are those that share a side. Let's say angle A and angle B are adjacent angles in the parallelogram.

Since opposite angles of a parallelogram are congruent, we have angle A is congruent to angle C, and angle B is congruent to angle D.

Now, let's consider angle A and angle B. The sum of angle A and angle B is equal to the sum of angle C and angle D because opposite angles are congruent.

Therefore, we can conclude that angle A + angle B = angle C + angle D = 180 degrees.

This property holds true for all parallelograms. So, in any parallelogram, the adjacent angles are always supplementary, meaning their sum is 180 degrees.

For the given question, we know x° + 68° = 180°.

Then x° = 180° - 68°

x° = 112°

Answer:

after 13 hours, there would be approximately 1,252 bacteria in the petri dish.

Step-by-step explanation:

Here are the steps to solve this problem:

Identify the given information. We are told that there are 830 bacteria in a petri dish and that the number of bacteria can double every 28 hours.

Write the formula for exponential growth. In this case, we are dealing with exponential growth because the number of bacteria is doubling over time. The formula for exponential growth is:

N = N0 * 2^(t/k)

where N0 is the initial amount, N is the amount after time t, and k is the time it takes for the amount to double.

Substitute the given values into the formula. We can plug in N0 = 830, t = 13, and k = 28 into the formula to get:

N = 830 * 2^(13/28)

Solve the equation. We can use a calculator or perform the calculation by hand to get:

N ≈ 1,251.7

Round to the nearest whole number. Since we're asked to round to the nearest whole number, we can look at the decimal part of the answer and round up or down as appropriate. In this case, the decimal part is 0.7, which is greater than or equal to 0.5, so we round up to get:

N ≈ 1,252

Therefore, after 13 hours, there would be approximately 1,252 bacteria in the petri dish.

Explanation:

The formula we use is

y = a*2^(x/b)

where,

So we update things to get y = 830*2^(x/28)

The last step is to plug in x = 13 to get

y = 830*2^(13/28) = 1145.09631988669 approximately

That rounds to 1145 when rounding to the nearest whole number.

The number of pounds when the costs of shipping with UPS and FedEx are the same is 31.25 pounds.

Based on the information given, the cost for ground shipping with FedEx will be 9.50 + 0.16x

The cost for ground shipping with UPS will be 8.25 + 0.20x

Therefore, in order to know the number of pounds when the costs of shipping with UPS and FedEx are the same, we'll have to equate both equations and this will be:

8.25 + 0.20x = 9.50 + 0.16x

Collect like terms

0.20x - 0.16x = 9.50 - 8.25

0.04x = 1.25

x = 1.25/0.04

x = 31.25
