Answer:
(-6, 4/3, 7)
Step-by-step explanation:
To solve the system of equations, we can use elimination or substitution. Here, we will use elimination:
First, we can eliminate z by adding the first and third equations:
x - 3y - 5z = 7
6x + 5y - 6z = 85
7x + 2y = 92
Next, we can use the second equation to eliminate z from the second equation:
6y + z = 27
-6z from both sides:
6y = -6z + 27
Divide both sides by 6:
y = -z/6 + 9/2
Now, we can substitute y = -z/6 + 9/2 into the equation 7x + 2y = 92:
7x + 2(-z/6 + 9/2) = 92
7x - z/3 + 9 = 92
7x - z/3 = 83
Multiplying both sides by 3 to eliminate the fraction:
21x - z = 249
We now have two equations:
7x + 2y = 92
21x - z = 249
To eliminate x, we can multiply the first equation by 3 and subtract it from the second equation:
21x - z = 249
- (3 * (7x + 2y = 92))
-----------------------------------------------------------------
-13x - 6z = -215
Solving this equation for z, we get:
-13x - 6z = -215
6z = 13x + 215
z = (13/6)x + 35 + 1/3
Now we can substitute this value of z into one of the equations to solve for y. Let's use the second equation:
6y + z = 27
6y + [(13/6)x + 35 + 1/3] = 27
6y + (13/6)x + 35 + 1/3 - 27 = 0
6y + (13/6)x + 8 + 1/3 = 0
6y + (13/6)x = -25/3
y = (-13/36)x - (25/18)
Finally, we can substitute these values for x, y, and z into one of the original equations to check our work. Let's use the first equation:
x - 3y - 5z = 7
x - 3[(-13/36)x - (25/18)] - 5[(13/6)x + 35 + 1/3] = 7
x + (13/12)x + (25/6) - (65/6)x - 175 - (5/3) = 7
-51x/12 - 215/6 = 7
-17x/4 - 35/2 = 7
-17x/4 = 21/2
x = -6
Substituting this value of x into the expressions we found for y and z, we get:
y = (-13/36)x - (25/18) = (13/6) - (25/18) = 4/3
z = (13/6)x + 35 + 1/3 = -(13/6)*6 + 35 + 1/3 = 7

Explain why a rating of 6 is not a good description of the center of this data set.
After answering the provided question, we can state that As a result, expression rather than a rating of 6, it would be more appropriate to use the median to describe the centre of this data set.
what is expression ?An expression in mathematics is a collection of interpretations, digits, and transnational corporations that resemble a causative link or regimen. A real number, a mutable, or a combination of the two can be used as an expression. Mathematical operators include extension, subtraction, rapid spread, separation, and exponentiation. Expressions are widely used in arithmetic, mathematics, and shape. They are used in the representation of mathematical formulas, the solution of equations, and the simplification of mathematical relationships.
Because the dot plot is not symmetrical and the distribution appears to be skewed towards higher ratings, a rating of 6 may not be a good description of the centre of this data set. The numbers 8, 9, and 10 are more common than the numbers 0-7, indicating that the data set has a right skew.
As a result, the centre of the data set may be better described by a measure of central tendency that accounts for data skewness, such as the median.
As a result, rather than a rating of 6, it would be more appropriate to use the median to describe the centre of this data set.

The table shows the temperature of a pizza over four-minute intervals after it is removed from the oven.
Time, (x) 0 4 Temperature, (y) 450 340
Create a model describing the data and use it to predict the temperature after 20 minutes
The temperature of the pizza after 20 minutes will be 25 degrees.
Define the term slope?the slope refers to the measure of the steepness or inclination of a line.
We can create a linear model to describe the relationship between time and temperature.
So, slope (m) = [tex]\frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Using the temperature and time values from the first and last data points:
m = [tex]\frac{(145 - 450)}{(16 - 0)}[/tex]
m = -305/16
Using the point-slope form of the equation of a line, we can now ascertain the equation of the line:
y - y₁ = m(x - x₁)
Using the first data point (0, 450);
y - 450 = (-305/16)(x - 0)
Simplifying, y = (-305/16)x + 450
To predict the temperature after 20 minutes, we can plug in x = 20 and solve for y:
y = (-305/16)(20) + 450
y = -950/16 + 450
y = 25
Therefore, we can predict that the temperature of the pizza after 20 minutes will be approximately 25 degrees.

Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $2,600 was collected on the sale of 1,160 tickets. How many of each type of ticket were sold?
Answer:
360 adult tickets and 800 student tickets were sold.
Step-by-step explanation:
Let's use a system of equations to solve this problem.
Let x be the number of adult tickets sold, and y be the number of student tickets sold. We know that a total of 1,160 tickets were sold, so:
x + y = 1160
We also know that the total amount collected was $2,600. The amount collected from adult tickets is $5 times the number of adult tickets sold, and the amount collected from student tickets is $1 times the number of student tickets sold. So:
5x + 1y = 2600
Now we have a system of two equations:
x + y = 1160
5x + y = 2600
We can solve for one of the variables in terms of the other, and substitute into the other equation to solve for the remaining variable. For example, we can solve the first equation for y:
y = 1160 - x
Now substitute this expression for y into the second equation:
5x + (1160 - x) = 2600
Simplifying and solving for x:
4x + 1160 = 2600
4x = 1440
x = 360
So 360 adult tickets were sold. To find the number of student tickets sold, we can use either equation. Let's use the first equation:
x + y = 1160
360 + y = 1160
y = 800
So 800 student tickets were sold.
Therefore, 360 adult tickets and 800 student tickets were sold.

suppose that iq scores have a bell-shaped distribution with a mean of 96 and a standard deviation of 17 . using the empirical rule, what percentage of iq scores are greater than 79 ? please do not round your answer.
Using the empirical rule, the percentage of IQ scores that are greater than 79 is 84%.
The empirical rule, also known as the 68-95-99.7 rule, states that for a normal distribution:
Approximately 68% of the data falls within one standard deviation of the mean.Approximately 95% of the data falls within two standard deviations of the mean.Approximately 99.7% of the data falls within three standard deviations of the mean.Since we know that the mean is 96 and the standard deviation is 17, we can calculate how many standard deviations away from the mean an IQ score of 79 is:
(79 - 96) / 17 = -1
This means that an IQ score of 79 is one standard deviation below the mean. This also means that approximately 68% of the data falls between 79 and (96 + 17) = 113.
Meanwhile, approximately 32% of the data falls outside of one standard deviation. We can say that half of this 32% are scores less than 79 and the other half are scores greater than 113. So the percentage of IQ scores greater than 79 is:
100 - (1/2 of 32) = 84%

The minimum sample size required to ensure that the estimate has an error of at most 0.15 at the 99% level of confidence = 426
Here, the population variance is σ² = 1.44
The mean is [tex]\bar{x}[/tex] = 6
And the margin of error is E = 0.15
The standard deviation is given by,
⇒ σ = [tex]\sqrt{1.44}[/tex]
⇒ σ = 1.2
Here, the confidence level is 99%
So, the level of signoficance would be,
⇒ α = (100 - 99)%

On a recent quiz, the class mean was 77 with a standard deviation of 2. Calculate the z-score (to 2
decimal places) for a person who received score of 72.
Z-score:
Is this unusual?
O Not Unusual
O Unusual
The answer is that the z score is unusual. We can calculate it in the following manner.
To calculate the z-score for a score of 72, we can use the formula:
z = (x - μ) / σ
where x is the individual score, μ is the mean, and σ is the standard deviation.
Substituting the given values, we get:
z = (72 - 77) / 2 = -2.5
Rounding to two decimal places, the z-score is -2.50.
To determine if this z-score is unusual, we need to compare it to a standard normal distribution. In a standard normal distribution, about 95% of the data falls within 2 standard deviations of the mean (i.e., between a z-score of -2 and +2). A z-score beyond this range is generally considered unusual.
Since the z-score for a score of 72 is beyond this range (i.e., it is less than -2), it is considered unusual.
Therefore, the answer is:
Unusual

In an inverse variation as one value increases, the other decreases. Option D
what happens to the values of the two variables in an inverse variationInverse variation is a mathematical relationship between two variables in which the product of the two variables is a constant. In other words, if the value of one variable increases, then the value of the other variable decreases in such a way that their product remains constant.
For example, if y is inversely proportional to x, then we can write it as y = k/x, where k is the constant of variation. As x increases, y must decrease to keep the product of x and y constant.
So, the correct answer is D, as one value increases, the other decreases. As one value decreases, the other increases to maintain the constant product. Inverse variation is also called inverse proportionality.

The function to represent the average cost of each satellite television subscription per month would be:
f(x) = (140 + 30x) / 60 for the Orbit company
f(x) = (20 + 35x) / 60 for the Vision company
What is time complexity?
Time complexity refers to the amount of time an algorithm or program takes to run as the input size increases. It is a measure of the efficiency of an algorithm, and it is usually expressed in terms of the "big O" notation.
Cost of Orbit company subscription
= $140 + ($30/month * 12 months * 5 years) = $2140
Cost of Vision company subscription
= $20 + ($35/month * 12 months * 5 years) = $2120
Therefore, the average cost of each satellite television subscription per month for the given period is:
(Cost of Orbit subscription + Cost of Vision subscription) / (12 months * 5 years) = ($2140 + $2120) / (12 * 5) = $35.67 per month
Time complexity O(1), and space complexity V(1) because the calculation only involves basic arithmetic operations and a fixed number of variables.
So, the function to represent the average cost of each satellite television subscription per month would be:
f(x) = (140 + 30x) / 60 for the Orbit company
f(x) = (20 + 35x) / 60 for the Vision company

What is the cοst?The cοst οf anything is the sum οf mοney οr resοurces that must be used up in οrder tο acquire οr manufacture it. It is a measurement οf the cοsts incurred tο attain a specific οbjective οr result.
The expressiοn tο represent the cοst οf Karina's theme park trip wοuld be:
38 + 10 + 4h + (1/2)r
This includes the $38 entry price, the $10 lunch expense, and the $4 per hοur parking expense fοr the 72 hοurs. Given that Karina and her friend are splitting the cοst οf the hοtel rοοm, the final phrase (1/2)r denοtes Karina's pοrtiοn οf the expense.
If the hοtel rοοm fοr Karina and her friend cοsts $86 and they park fοr 7 hοurs, we can change these values intο the fοrmula tο make it simpler:
= 38 + 10 + 4(7) + (1/2)(86)
= 38 + 10 + 28 + 43
= $119
Therefοre, Karina will pay $119 fοr her theme park trip.

All exponential functions can be written in many forms. Write the function
f(t) = 750(0.65) ^t\35 in the form f(t) =ab^t. Round all coefficients to four decimal
places.
The final form of the exponential function is: f(t) = 750(0.8825)raise to the power t
what is exponential function?
An exponential function is a mathematical function of the form f(x) = a to the power x, where "a" is a positive constant (called the base of the exponential function) and "x" is a variable that can take on any real number value.
The key property of an exponential function is that the output value (or "y" value) grows or decays at a constant rate as the input value (or "x" value) increases or decreases. This constant rate of growth or decay is determined by the base "a" of the function.
When the base "a" is greater than 1, the function represents exponential growth, where the output value increases rapidly as the input value increases. When the base "a" is between 0 and 1, the function represents exponential decay, where the output value decreases rapidly as the input value increases.
Exponential functions are commonly used to model natural phenomena such as population growth, radioactive decay, and compound interest. They also have many applications in science, engineering, economics, and finance.
Starting with the given exponential function:
f(t) = 750(0.65)raise to the power (t/35)
We can rewrite 0.65 as 0.65, and 35 as 5 * 7. Then we have:
f(t) = 750(0.65)raise to the power (t/(5*7))
Using the exponent rule that (a to the power b)to the power c = a to the power (bc), we can simplify the expression inside the parentheses:
f(t) = 750(0.65 to the power (t/5))⁷
Letting a = 750 and b = 0.65 to the power(1/5), we can write the function in the desired form:
f(t) = ab to the power , where a ≈ 750 and b ≈ 0.8825 (rounded to four decimal places)
Therefore, the final form of the exponential function is:
f(t) = 750(0.8825) to the power t

For each of the following story problems, determine whether the problem can be solved by subtracting 1 2 − 1 3. If not, explain why not, and explain how the problem should be solved if there is enough information to do so. If there is not enough information to solve the problem, explain why not. Zelha pours 1 2 cup of water into an empty bowl and then pours out 1 3. How much water is in the bowl now? Zelha pours 1 2 cup of water into an empty bowl and then pours out 1 3 cup of water. How much water is in the bowl now? Zelha pours 1 2 cup of water into an empty bowl and then pours out 1 3 of the water that is in the bowl. How much water is in the bowl now? Yesterday James ate 1 2 of a pizza, and today he ate 1 3 of a pizza of the same size. How much more pizza did James eat yesterday than today? Yesterday James ate 1 2 of a pizza, and today he ate 1 3 of the whole pizza. Nobody else ate any of that pizza. How much pizza is left? Yesterday James ate 1 2 of a pizza, and today he ate 1 3 of the pizza that was left over from yesterday. Nobody else ate any of that pizza. How much pizza is left?
For problem (A), subtracting A and B alone cannot solve the problem as the result does not provide the amount of water left in the bowl, and for problem (B), subtracting A and B can solve the problem as it provides the amount of pizza left after James ate.
(A) This problem cannot be solved by subtracting A and B. If we subtract 1/3 from 1/2, we get 1/6, which is the amount of water that was poured out. However, this does not tell us how much water is left in the bowl. To solve the problem, we need to subtract 1/3 from 1/2 and then subtract the result from 1/2. This gives us
1/2 - 1/3 = 1/6
1/2 - 1/6 = 1/3
Therefore, there is 1/3 cup of water left in the bowl.
(B) This problem can be solved by subtracting A and B. If James ate 1/2 of the pizza yesterday and 1/3 of the pizza today, then he ate a total of
1/2 + 1/3 = 5/6
of the pizza. Therefore, the amount of pizza left is:
1 - 5/6 = 1/
