Answer:

x = 3

y = 7

Step-by-step explanation:

3x - y = 2                                  Y = 2x - 1

3x - 2x - 1 = 2

x - 1 = 2

x = 3

Now put 3 in for x and solve for y

3(3) - y = 2

9 - y = 2

- y = -7

y = 7

Let's check

3(3) - 7 = 2

9 - 7 = 2

2 =2

So, x = 3 and y = 7 is the correct answer.

Number line  that represents the solution to |x − 21| < 3 is C.

Tο sοlve the inequality |x - 21| < 3, we need tο find all the values οf x that are less than 3 units away frοm 21 οn the number line.

Starting frοm 21, we can cοunt 3 units tο the left and 3 units tο the right tο find the interval οf values that satisfy the inequality:

| x - 21 | < 3 can be written as -3 < x - 21 < 3

Adding 21 tο all parts οf the inequality gives:

18 < x < 24

Therefοre, the sοlutiοn tο the inequality is the interval οf values between 18 and 24, excluding the endpοints.

Lοοking at the answer chοices, we can see that οptiοn C represents this interval οf values:

The correct answer is "The extreme value theorem applies, and f(x) has both a minimum and a maximum."

What is the extreme value theorem?

The extreme value theorem states that if a function is continuous on a closed interval, then it must have both a maximum and a minimum value on that interval. To determine whether the extreme value theorem applies to the graph of f(x), we need to check if the function is continuous on a closed interval and whether it has a highest and lowest point within that interval.

Looking at the graph of f(x), we can see that the function is continuous on the closed interval [-3, 3] since it has no breaks or jumps. Additionally, the graph has the highest point at (1, 2) and the lowest point at (-3,-2). Therefore, we can conclude that the extreme value theorem applies and that f(x) has both a minimum and a maximum value on the interval [-3, 3].

Therefore, the correct answer is (a) "The extreme value theorem applies, and f(x) has both a minimum and a maximum."

Exponentiation, sometimes known as "raising b to the nth power," is a substitution cipher that includes two numbers: a base quantity, b, and an argument, meaning power, n. Exponents represent the number of times a value has been increased by itself. As an example, 2-3 (represented as 23) represents: 2 x 2 x 2 = 8. 2 + 3 = 6 does not equal 23. Remember that an integer multiplied by one equals itself. Exponents are a method for expressing large numbers as powers. The amount that represents however many times a statistic has already been amplified by itself is called the exponent. As an example, multiplying 6 by 4 yields 6 x 6 x 6.

Using exponent principles and the square root of perfect squares, we may simplify sqrt(196y8) as follows:

[tex]\sqrt(196y8) = \sqrt((142*(y4)2) [since 196 = 142 and (y4)2 = y8]\\\sqrt(142) * \sqrt((y4)2) [using the \sqrt(ab) = \sqrt(a) * \sqrt(b) rule]\\= 14y^4[/tex]

Step-by-step explanation:

$10 per unit means 1 unit is equivalent to 10 dollars.

∴Unit multiplier = [tex]\frac{10 dollars}{unit}[/tex]

$5 per unit means 1 unit is equivalent to 5 dollars

∴Unit multiplier = [tex]\frac{5 dollars}{unit}[/tex]

Remaining units = 1000 - 100 = 900 units

The unit multipliers are arranged in such a way that the "units” in the numerator and denominator will cancel each other out leaving us with “dollars” in the numerator. Our answer should be expressed in dollars
since the question requires us to calculate the bill

Bill of the House = Charge of first 100 units + Charge of remaining units

                            = (1000 units)([tex]\frac{10dollars}{unit}[/tex]) + [(900)units][[tex]\frac{5dollars}{unit}[/tex]]

The probability that a randomly selected adult has an IQ between 93 and 117 is approximately 0.6827 or 68.27%.

What is probability?

Probability is a branch of mathematics that deals with the study of random events and their outcomes. It is the measure of the likelihood of an event occurring, expressed as a number between 0 and 1.

To find the probability that a randomly selected adult has an IQ between 93 and 117, we need to standardize the distribution using the z-score formula, and then find the area under the normal distribution curve between those two z-scores.

The z-score formula is:

z = (x - μ) / σ

where x is the IQ score we are interested in, μ is the mean IQ score, and σ is the standard deviation of IQ scores.

For the lower bound of 93, the z-score is:

z = (93 - 105) / 20 = -0.6

For the upper bound of 117, the z-score is:

z = (117 - 105) / 20 = 0.6

Now, we need to find the area under the normal distribution curve between these two z-scores. We can use a standard normal distribution table or a calculator to find this probability. Using a calculator, we can use the normalcdf function:

normalcdf(-0.6, 0.6, 0, 1)

This gives us a probability of 0.6827.

Therefore, the probability that a randomly selected adult has an IQ between 93 and 117 is approximately 0.6827 or 68.27%.

The normal probability plot is a useful tool for assessing the normality of a sample of data. By plotting the sample values against the quantiles of a normal distribution, one can quickly determine whether the data could have come from a population that is normally distributed.

Sample data is a subset of data taken from a larger population. It is used to estimate the characteristics of the larger population. Sample data is usually collected using a variety of methods such as surveys, experiments, and simulations. It is important to select a sample that accurately represents the population in order to draw reliable conclusions.

A normal probability plot is a graphical tool used to assess whether or not a sample of data could have come from a population that is normally distributed. The data is plotted on a graph, with the x-axis representing the sample values and the y-axis representing the quantiles of a normal distribution. If the points form a straight line, then the population is normally distributed.

In this situation, the sample data being studied is the wall thickness of O-rings. To create the normal probability plot, each sample value should first be converted to a standard normal deviate, which can be found using the standard normal distribution table. The standard normal deviate is then plotted against the sample values, and the points are connected to form a line. If the line is straight, then it can be concluded that the sample data could have come from a population that is normally distributed. If the line is curved, then the data does not fit the normal distribution.
