Find the real zeros of each polynomial function by factoring. The number in parentheses to the right of each polynomial indicates the number of real zeros of the given polynomial function. (Enter your answers as a comma-separated list. )
P(x) = x5 − 50x3 + 49x (5)
Answers
The real zeros of the polynomial function P(x) = x⁵ − 50x³ + 49x are -1, 0, and 1.
To find the zeros of this function, we can factor it by first factoring out an x to get P(x) = x(x⁴ − 50x² + 49). Then, we can factor the quadratic expression inside the parentheses using the difference of squares formula, which gives us P(x) = x(x² − 1)(x² − 49). Simplifying further, we have P(x) = x(x − 1)(x + 1)(x - 7)(x + 7).
Therefore, the zeros of P(x) are the values of x that make each factor equal to zero. This gives us x = -7, -1, 0, 1, and 7. Since all of these values are real, we conclude that the number of real zeros of P(x) is 5.

Dry ice is solid carbon dioxide. It’s temperature is about -98°C. how much less is this temperature than room temperature, which is about 20°C
Answers
To find how much less the temperature of dry ice is than room temperature, we need to subtract the temperature of dry ice from the temperature of room temperature.
The formula is:difference = room temperature - dry ice temperature
We can plug in the given values:
difference = 20°C - (-98°C)
We can simplify the expression by adding 98°C to both sides:
difference + 98°C = 20°C + 98°C
difference = 118°C
Therefore, the temperature of dry ice is 118°C less than room temperature.

During the rebuilding after World War II, we were short of tractors. The machine and tractor stations would lend each other equipment as needed. Three machine and tractor stations were neighbors. The first lent the second and third as many tractors as they each already had. A few months later, the second lent the first and third as many as they each had. Still later, the third lent the first and second as many as they each already had. Each station now had 24 tractors.
How many tractors did each station originally have?
Answers
The number of tractors lent by the first, second and third stations results in a system of three simultaneous equations which indicates;
The first originally station had 39 tractors, the second station had 21 tractors and the third station originally had 12 tractors
What are simultaneous equations?Simultaneous equations are a set of two or more equations that have common variables.
Let x represent the number of tractors at the first station, let y represent the number of tractors at the second tractor station, and let z, represent the number of tractors at the third tractor station
According to the details in the question, after the first transaction, we get
Number of tractors at the first station = x - y - z
Number of tractors at the second station = y + y = 2·y
Number of tractors at the third station = z + z = 2·z
After the second transaction, we get;
Number of tractors at the first station = 2·x - 2·y - 2·z
Number of tractors at the second station = 2·y - (x - y - z) - 2·z = 3·y - x - z
Number of tractors at the third station = 2·z + 2·z = 4·z
After the third transaction, we get;
Number of tractors at the first station = 2 × (2·x - 2·y - 2·z) = 4·x - 4·y - 4·z
Number of tractors at the second tractor station = 6·y - 2·x - 2·z
Number of tractors at the third tractor station = 4·z - (2·x - 2·y - 2·z) - (3·y - x - z) = 7·z - x - y
The three equations after the third transaction are therefore;
4·x - 4·y - 4·z = 24...(1)
6·y - 2·x - 2·z = 24...(2)
7·z - x - y = 24...(3)
Multiplying equation (2) by 2 and subtracting equation (1) from the result we get;
12·y - 4·x - 4·z - (4·x - 4·y - 4·z) = 16·y - 8·x = 48 - 24 = 24
16·y - 8·x = 24...(4)
Multiplying equation (3) by 2 and multiplying equation (2) by 7, then adding both results, we get;
14·z - 2·x - 2·y = 48
42·y - 14·x - 14·z = 168
42·y - 14·x - 14·z + (14·z - 2·x - 2·y) = 48 + 168
40·y - 16·x = 216...(5)
Multiplying equation (4) by 2 and then subtracting the result from equation (5), we get;
40·y - 16·x - (32·y - 16·x) = 216 - 48 = 168
8·y = 168
y = 168/8 = 21
The number of tractors initially at the second station, y = 21
16·y - 8·x = 24, therefore, 16 × 21 - 8·x = 24
8·x = 16 × 21 - 24 = 312
x = 312 ÷ 8 = 39
The number of tractors initially at the first station, x = 39
7·z - x - y = 24, therefore, 7·z - 39 - 21 = 24
7·z = 24 + 39 + 21 = 84
z = 84/7 = 12
The number of tractors initially at the third station, z = 12

Create one symmetrical (normal) and one asymmetrical set of data, and explain why each fit the definition.
- Knowing the type of distribution and the skewness of the data, is it possible to draw conclusions about the mean and the median?
- Why would it be best to use particular measures of center and spread if the data is symmetrical or asymmetrical?
- What measures would you use in each case?
Answers
If the data is symmetrical, then the mean is the best measure of central tendency to use, and the standard deviation is the best spread to use.
If the data is asymmetrical, the median is the best measure of central tendency to use, and the inter-quarterly range is the best spread to use.
What are symmetrical and asymmetrical data?A histogram for symmetrical data will give a symmetrical shape, and the mean, median and mode will all be the same value. Therefore, the best measure of the central tendency to use is the mean. The standard deviation shows how far away the values in a given data set are from the mean, and since the mean is used as the measure of central tendency in this case, the standard deviation should be used as the spread.
A histogram for a an asymmetric data set will give an asymmetric shape, and the mean is not always equal to the median. Therefore, the best measure of central tendency to use is the median. The inter-quarterly range shows the range of the middle 50% of a certain data, which is considered from the median value. Since the median is used as the measure of central tendency in this case, it is wise to use the inter-quarterly range as the measure of spread.

What is percent?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement. Rather than being stated as a fraction, a percentage is a piece of a whole expressed as a number between 0 and 100. Nothing is zero percent; everything is 100 percent; half of something is 50 percent; and nothing is zero percent. You divide the part of the whole by the whole and multiply the result by 100 to get the percentage.
Here,
Market value of the stocks:
Year 1: 2,645 million
Year 2: 2,957 million
Year 3: 3,318 million
Year 4: 3,193 million
Year 5: 3,742 million

Year 2: 1,117.96
Year 3: 1,254.44
Year 4: 1,207.18
Year 5: 1,414.74
Calculations:
Year 1: 2,645 million / 2,645 million × 1,000 = 1,000.00
Year 2: 2,957 million / 2,645 million × 1,000 = 1,117.96
Year 3: 3,318 million / 2,645 million × 1,000 = 1,254.44
Year 4: 3,193 million / 2,645 million × 1,000 = 1,207.18
Year 2: 3,742 million / 2,645 million × 1,000 = 1,414.74
Since the index starts at 1,000 points, the values for the subsequent years will be Year 1: 1,000, Year 2: 1,117.96, Year 3: 1,254.44, Year 4: 1,207.18, and Year 5: 1,414.74.

Answers
The simplified equation is: \(7x^2 - 13x - 19 = 0\), its a quadratic eqution.
What is simplification ?
Simplification refers to the process of reducing a mathematical expression into a simpler or more compact form. This is often done by combining like terms, factoring out common factors, and simplifying fractions. The goal of simplification is to make expressions easier to work with and to better understand their properties and relationships. Simplification is an important skill in algebra and other branches of mathematics.
According to the question:
First, let's simplify the right-hand side of the equation by distributing the negative sign:
\((x - 5) (5 - x) = -x^2 + 5x - 5x + 25 = -x^2 + 25\)
Now, let's expand the left-hand side using FOIL (First, Outer, Inner, Last):
\((2x - 3) (3x - 2) = 6x^2 - 4x - 9x + 6\)
Simplifying this expression by combining like terms, we get:
\(6x^2 - 13x + 6 = -x^2 + 25\)
Moving all the terms to one side, we get:
\(7x^2 - 13x - 19 = 0\)
Therefore, the simplified equation is:
\(7x^2 - 13x - 19 = 0\)

a bag contains red marbles and blue marbles. zuri randomly removes marbles from the bag, one at a time and without replacement, and stops when she has removed all the red marbles from the bag. what is the expected value of the number of marbles zuri removes from the bag?
Answers
The expected value of the number of marbles Zuri removes from the bag is the sum of the number of red marbles plus the number of blue marbles.
The expected value of the number of marbles Zuri removes from the bag is the sum of the number of red and blue marbles. This is because the expected value of an event is the sum of the probability of each outcome multiplied by the associated outcome. Since Zuri is randomly removing marbles from the bag, one at a time and without replacement, the probability of each outcome (red or blue) is equal. Therefore, the expected value of the number of marbles Zuri removes from the bag is the sum of the number of red marbles plus the number of blue marbles. This is because each marble has an equal chance of being removed and, therefore, each marble has the same expected value.

a senate committee has 5 democrats, 5 republicans, and 1 independent. in how many ways can they sit around a circular table if all the members of each party all sit next to each other? (two seatings are considered equivalent if one is a rotation of the other.)
Answers
There are 7200 ways for the senate committee to sit around a circular table.
To solve this problem, we can use the formula for circular permutations: (n-1)!/d, where n is the total number of people and d is the number of ways in which they can be distinguished. In this case, n is 11 (5 democrats + 5 republicans + 1 independent) and d is 1 (since all the members of each party sit together, they are not distinguishable from one another). Plugging these values into the formula, we get
(11-1)!/1 = 10!/1 = 1098765432*1/1 = 7200.This means that there are 7200 ways for the senate committee to sit around a circular table.

Jon has a photograph that measures 4 inches wide by 6 inches long. He asked a photo shop to reproduce the photo 25% larger. What will the new dimensions be?
Answers
The new dimensions of the photograph will be 5 inches by 7.5 inches.
What is measurement?
Measurement is the process of assigning numerical values to physical quantities, such as length, mass, time, temperature, and volume, in order to describe and quantify the properties of objects and phenomena.
If the photograph is reproduced 25% larger, then each dimension will be increased by 25% of its original value.
The new width will be:
4 inches + (25% of 4 inches) = 4 inches + 1 inch = 5 inches
The new length will be:
6 inches + (25% of 6 inches) = 6 inches + 1.5 inches = 7.5 inches
Therefore, the new dimensions of the photograph will be 5 inches by 7.5 inches.
