The lower confidence level (LCL) and upper confidence level (UCL) are

a. X-Bar = 47; n = 73; 0 = 31; a = 0.05
LCL = 44.35
UCL = 49.65

b. X-Bar = 83; n = 221; 0 = 400; a = 0.01
LCL = 79.91
UCL = 86.09

c. X-Bar = 513; n = 425; 0 = 43; a = 0.10
LCL =  509.27
UCL = 516.73

a. X-Bar = 47, n = 73, σ² = 31, α = 0.05

Using the formula for a confidence interval for the mean of a normal distribution with known variance, we get:

LCL = X-Bar - z(α/2) * √(σ²/n)

= 47 - 1.96 * √(31/73)

= 44.35

UCL = X-Bar + z(α/2) * √(σ²/n)

= 47 + 1.96 * √(31/73)

= 49.65

So, the 95% confidence interval for the population mean is (44.35, 49.65).

b. X-Bar = 83, n = 221, σ^2 = 400, α = 0.01

Using the same formula, we get:

LCL = X-Bar - z(α/2) * √(σ²/n)

= 83 - 2.58 * √(400/221)

= 79.91

UCL = X-Bar + z(α/2) *√(σ²/n)

= 83 + 2.58 * √(400/221)

= 86.09

So, the 99% confidence interval for the population mean is (79.91, 86.09).

c. X-Bar = 513, n = 425, σ² = 43, α = 0.10

Again, using the same formula, we get:

LCL = X-Bar - z(α/2) * √(σ²/n)

= 513 - 1.645 * √(43/425)

= 509.27

UCL = X-Bar + z(α/2) * √(σ²/n)

= 513 + 1.645 * √(43/425)

= 516.73

So, the 90% confidence interval for the population mean is (509.27, 516.73).

a) We need to find the values of x for which the denominator, cos(x), is equal to zero. b) vertical asymptotes at x = π/2, x = 3π/2, x = -π/2, x = -3π/2, and so on.

The tangent function is periodic, with a period of π radians (or 180 degrees). This means that the tangent function repeats itself every π radians, or every 180 degrees. The tangent function is also an odd function, which means that it is symmetric about the origin.

The graph of the tangent function has a characteristic shape with multiple cycles between consecutive vertical asymptotes. The graph passes through the origin and intersects the x-axis at the vertical asymptotes. The tangent function has a maximum and a minimum value between any two consecutive vertical asymptotes. However, it does not have a maximum or minimum value over its entire domain.

a) To determine the exact location of the asymptotes of the tangent function using the identity tan(x) = sin(x)/cos(x), we need to find the values of x for which the denominator, cos(x), is equal to zero. These values of x correspond to the vertical asymptotes of the tangent function.

Since cos(x) = 0 when x = π/2 + kπ, where k is an integer, the vertical asymptotes of the tangent function occur at these values of x. We can also write this as x = kπ/2, where k is an odd integer.

b) From the graph of the tangent function, we can see that there are vertical asymptotes at x = π/2, x = 3π/2, x = -π/2, x = -3π/2, and so on. These correspond to the values of kπ/2, where k is an odd integer. We can also write the set of vertical asymptotes as:

Answer:

6 $6 books

Step-by-step explanation:

Using the information, we can create a system of equations.

We can let x represent the total number of $6 Marci bought and y represent the total number of $8 books she bought.

Because the total number of books is 10, one equation we have is x + y = 10.

Because the total cost of both types of books is $68, our other equation is 6x + 8y = 68.

We can solve with substitution by isolating y in the first equation and plugging it into the second equation:

[tex]x+y=10\\y=-x+10\\\\6x+8(-x+10)=68\\6x-8x+80=68\\-2x+80=68\\-2x=-12\\x=6[/tex]

Thus, the total number of $6 books Marci bought was 6.

The resultant of the expression (((-3/5)+(5/3))-(2-4/3)) will be 2/5.

What exactly are expressions?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations that can be evaluated to produce a value. Expressions can be as simple as a single number or variable, or they can be more complex, involving multiple numbers, variables, and operations.

For example, 3 + 5 is an expression that represents the sum of two numbers, which evaluates to 8. Another example is 2x - 5, which involves a variable (x) and two operations (multiplication and subtraction).

Now,

Let's start by simplifying (-3/5 + 5/3):

First, we need to find a common denominator between 5 and 3, which is 15

then,

-3/5 + 5/3 = -9/15 + 25/15

Next, we can add the two fractions:

-9/15 + 25/15 = 16/15

So, (-3/5 + 5/3) simplifies to 16/15.

Now, let's simplify (2 - 4/3):

We can rewrite 2 as 6/3, then subtract 4/3:

6/3 - 4/3 = 2/3

So, (2 - 4/3) simplifies to 2/3.

Finally, we can subtract 2/3 from 16/15:

16/15 - 2/3

To subtract fractions, we need a common denominator between 15 and 3, which is 15. then

16/15 - 10/15 = 6/15

So, the resulting constant is 6/15, which can be simplified by dividing both the numerator and denominator by their greatest common factor (which is 3):

6/15 = 2/5

Therefore,

                the resulting constant is 2/5.

In the following question, among the conditions given, This triangle must be a non-Euclidean triangle, which is not possible to draw on a flat plane without distorting its shape. Therefore, there are no valid angles for this triangle.

To find the angles of a triangle when given the lengths of its sides, we can use the Law of Cosines, which states that:

c^2 = a^2 + b^2 - 2ab*cos(C)

where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Using this formula, we can find the cosine of each angle and then use the inverse cosine function (cos^-1) to find the measure of each angle.

Let's use this formula to find the angles of the triangle with sides of 11, 10, and 17:

c^2 = a^2 + b^2 - 2ab*cos(C)

For the side opposite angle C = 17:

17^2 = 10^2 + 11^2 - 2(10)(11)cos(C)

289 = 121 + 100 - 220cos(C)

cos(C) = (121 + 100 - 289)/(21011)

cos(C) = -0.4

We get a negative value for the cosine of angle C. This means that the triangle cannot be a standard triangle in the Euclidean plane, as the Law of Cosines requires that the cosine of an angle be between -1 and 1. This triangle must be a non-Euclidean triangle, which is not possible to draw on a flat plane without distorting its shape.

Therefore, there are no valid angles for this triangle.

Therefore , the solution of the given problem of inequality comes out to be   y - 12 = -(3/4)(x - 2)².

Without the equal sign, an association or collection of numbers can be a disparity in mathematics. Equity always comes after equilibrium. When standards are still incompatible, inequality results. Fairness and disparity have different variable characteristics. Because parts aren't always similar or close to one another, we decided to select the most common symbol (). It is also possible to use disparities of any size to assess values.

Here,

We must recast the parabola's equation in this form in order to determine the inequality's standard form. The vertex version of a quadratic equation is as follows:

=> y = a(x - h)² + k

where (h, k) is the parabola's apex. Inputting the numbers provided yields:

=> y = a(x - 2)² + 12

We can use the information that the parabola passes through (-2, 0) and to determine the value of a. (6, 0). When we enter these values into the formula, we obtain:

=> 0 = a(-2 - 2)² + 12

=> 0 = 16a + 12

=>  a = -3/4

The parabola's solution is as follows:

=>  y = -(3/4)(x - 2)²

If a scooter was brought in April 2005 for rs. 42000 if it's value fall by 10% every year, the value of the scooter in April 2007 would be Rs. 34020.

If the value of the scooter falls by 10% every year, then its value after the first year will be 90% of its original value. Similarly, the value after the second year will be 90% of the value after the first year, or 0.9 * 0.9 = 0.81 times the original value.

To find the value of the scooter in April 2007, we need to apply this formula twice, since there are two years between April 2005 and April 2007.

Starting with the original value of the scooter, we can calculate its value after one year:

Value after 1 year = 0.9 * Rs. 42000 = Rs. 37800

Then, we can use this value to calculate the value of the scooter after two years:

Value after 2 years = 0.9 * Rs. 37800 = Rs. 34020

The solution to |x| > |x + 2| is x < -2. This can be determined by looking at the two graphs on the grid, y = |x| and y = |x + 2|.

Inequality is the concept of representing a relationship between two values using a mathematical symbol. This can be used to express various forms of comparison such as greater than, less than, and not equal to. Inequality is an important concept for understanding and applying mathematical principles, such as in algebra and calculus.

The graph of y = |x| is a straight line at y = 0, and increases as x moves further away from 0. The graph of y = |x + 2| has a minimum at x = -2, and increases as x moves further away from -2. Therefore, at all locations where x is less than -2, the value of |x| is greater than the value of |x + 2|. These locations are all solutions to the inequality |x| > |x + 2|.

To visualize this solution, we can look at the graph of the two functions and see that the value of |x| is greater than the value of |x + 2| when x is less than -2. This can also be seen by looking at the numerical values of the two functions; for any x less than -2, the absolute value of x will be greater than the absolute value of x + 2.

In conclusion, the solution to the inequality |x| > |x + 2| is x < -2. This can be seen visually on the graph of the two functions, and can also be determined by looking at the numerical values of the two functions.

Comparing the two simplified ratios, 4:3 and 10:9, we see that they are not equal, so the ratios 60:45 and 10:9 do not form a proportion.

We must examine whether the cross-products are equal in order to determine whether the ratios of 60:45 and 10:9 constitute a proportion.

60 x 9 = 540 is the cross product of 60 and 9.

45 x 10 = 450 is the cross product of 45 and 10.

The cross-products are not equal, hence the ratios of 60:45 and 10:9 do not constitute a proportion (540 is not equal to 450, for example).

Simplifying two ratios to their simplest form is another technique to determine if they constitute a proportion.

The purchase cost is $40. Question: What is the discount price of shoes if they were originally $80 and are currently on sale for 50% off.  % formula: Sale price equals 50% of $80.

The word puzzle asks you to determine the sale price of shoes that are being offered at a 50% discount. The percent equation, which asserts that the percent of the whole is equal to the part over the entire, or percent = part/whole, may be used to solve this problem. In this instance, the sale price is the component we are interested in, the initial price of $80 is the component as a whole, and 50% is the percentage. With these numbers as inputs, we can calculate the sale price as 50% of $80. When we solve for the sale price, we arrive at $40. Hence, the sneakers are $40 on sale.
