In ΔWXY, w = 880 cm, ∠X=33° and ∠Y=38°. Find the length of y, to the nearest centimeter.
Answers
Answer:
[tex]y\approx573cm[/tex]
Step-by-step explanation:
First, take a look to the picture that I attached, however please note the triangle is not drawn to scale, the figure is just to provide visual aid. As you can see the value of [tex]\angle W =109^{\circ}[/tex] this is because of the sum of the interior angles in a triangle is always equal to 180°. So:
[tex]\angle W + \angle X + \angle Y =180\\\\\angle W = 180- \angle X -\angle Y\\\\\angle W =180-38-33\\\\\angle W=109[/tex]
Now, we can use the law of sines, which states:
[tex]\frac{w}{sin(W)} =\frac{x}{sin(X)} =\frac{y}{sin(Y)}[/tex]
Hence:
[tex]\frac{w}{sin(W)} =\frac{y}{sin(Y)}\\\\\frac{880}{sin(109)} =\frac{y}{sin(38)}\\\\Solving\hspace{3}for\hspace{3}y\\\\y=\frac{880*sin(38)}{sin(109)} \\\\y=572.9999518\approx 573 cm[/tex]

Your Cabaret nightspot "Jazz on Jupiter" has become an expensive proposition: You are paying monthly costs of $70,000 just to keep the place running. On top of that, your regular cabaret artist is charging you $2900 per performance, and your jazz ensemble is charging $800 per hour. Set up a (monthly) cost function for the scenario. (Let C represent the monthly cost in dollars, x represent the number of performances by the cabaret artist per month and y represent the number of hours of jazz per month.) C(x, y)
Answers
Answer:
The monthly cost function for the scenario C(x,y) is;
C(x,y) = 70,000 + 2900x + 800y
Step-by-step explanation:
Let C represent the monthly cost in dollars.
x represent the number of performances by the cabaret artist per month
and y represent the number of hours of jazz per month
Given;
monthly costs of $70,000
regular cabaret artist is charging you $2900 per performance.
Per month = $2900x
your jazz ensemble is charging $800 per hour.
Per month = $800y
The monthly cost function for the scenario C(x,y) is the sum of all the costs;
C(x,y) = 70,000 + 2900x + 800y

8. p-value=0.0047
Decision:
Because p-value less than Alpha=0.05, we reject null hypothesis.
Conclusion:
The data support the claim that the proportion has changed.
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
p = 3/4 = 0.75
For the alternative hypothesis,
p ≠ 0.75
Considering the population proportion, probability of success, p = 0.75
q = probability of failure = 1 - p
q = 1 - 0.75 = 0.25
Considering the sample,
Sample proportion, P = x/n
Where
x = number of success = 480
n = number of samples = 600
P = 480/600 = 0.8
We would determine the test statistic which is the z score
z = (P - p)/√pq/n
z = (0.8 - 0.75)/√(0.75 × 0.25)/480 = 2.53
Recall, population proportion, P = 0.75
The difference between sample proportion and population proportion(P - p) is 0.8 - 0.75 = 0.05
Since the curve is symmetrical and it is a two tailed test, the p for the left tail is 0.75 - 0.05 = 0.7
the p for the right tail is 0.75 + 0.05 = 0.8
These proportions are lower and higher than the null proportion. Thus, they are evidence in favour of the alternative hypothesis. We will look at the area in both tails. Since it is showing in one tail only, we would double the area
From the normal distribution table, the area above the test z score in the right tail 1 - 0.9943 = 0.0057
We would double this area to include the area in the left tail of z = - 2.53. Thus
p = 0.0057 × 2 = 0.0114
Because alpha, 0.05 > than the p value, 0.0114, then we would reject the null hypothesis.
Therefore, at 5% significance level, this data provide evidence that the proportion has changed.

Final answer:
The relationship between 1 and 2 in mathematics can refer to causality, ratios, probability, physical properties in physics, or reciprocal relationships, depending on the context.
Explanation:
The relationship between 1 and 2 can refer to various mathematical concepts, depending on the context in which these numbers are being used. Here are a few examples:
Causality: In a simple model with objects A and B, an arrow from A to B implies that A is the cause and B is the effect. It's a directional relationship.
Ratio: When we say the ratio between two quantities is 1:2, it implies for every unit of the first quantity, there are two units of the second quantity. In this case, RP1 to Rp2 is 1:2.
Probability: In the context of dice, if the first value is 2, the ratio could describe the possible outcomes when rolling two dice.
Physical properties: Mathematical relationships can be determined for variable pairs in physics such as Pressure (P) versus number of moles (n), or volume (V) versus temperature (T).
Reciprocity: In some mathematical expressions, swapping the subscripts '1' and '2' does not change the relationship, indicating a reciprocal or bidirectional relationship between the two.
Understanding these relationships requires recognizing the context and the mathematical principles that govern them.

What is the domain of the function Y equals cube root x
Answers
Final answer:
The domain of the function y = x^(1/3) (cube root of x) is all real numbers, which is expressed as (-∞, +∞).
Explanation:
The domain of a function describes all the possible values of 'x' for which the function is defined. In the case of the function y = cubic root of x, which is written as y = x^(1/3), the function is defined for all real numbers because you can take the cubic root of any real number, negative, positive, or zero. Hence, the domain of the function y = x^(1/3) is all real numbers, which mathematically is expressed as (-∞, +∞). This is different from the function y = x^2, where the domain must often be restricted to nonnegative numbers to have a well-defined real inverse function.

074 Inches.
Reset

Answers
Answer:
If the side length of a square is 4 inches, it's Area is 16 inches, and Perimeter is 16 inches.
Step-by-step explanation:
Given that the Area = s²
Perimeter = 4s
Side length of the square = s
If the length of a square is 4 inches, then applying the above formulas, we have
s = 4 inches
Area = 4² = 16 inches
Perimeter = 4s = 4×4 = 16 inches
Final answer:
The area of a square with a side length of 4 inches is 16 square inches and its perimeter is 16 inches. Doubling the side length to 8 inches yields an area that is four times greater, 64 square inches, due to the squared relationship between side length and area.
Explanation:
Understanding Square Area and Perimeter
A student has posed a question about the properties of squares. We are given that the side length of a square is 4 inches. From this, we can calculate the square's area and perimeter. The area of a square is found by squaring the length of its side (s2), which in this case would be 4 inches × 4 inches = 16 square inches. The perimeter is the length around the square, calculated by multiplying the side's length by 4, yielding 4 inches × 4 = 16 inches.
By understanding the formulas for area (s2) and perimeter (4s), students can solve many geometrical problems related to squares. For instance, if the dimensions of a square are to be doubled, the new side length would be 4 inches × 2 = 8 inches, resulting in an area of 8 inches × 8 inches = 64 square inches, which is four times the original area, demonstrating that the area scales with the square of the linear dimensions.

You are interested in purchasing a new car. One of the many points you wish to consider is the resale value of the car after 5 years. Since you are particularly interested in a certain foreign sedan, you decide to estimate the resale value of this car with a 99% confidence interval. You manage to obtain data on 17 recently resold 5-year-old foreign sedans of the same model. These 17 cars were resold at an average price of $ 12 comma 260 with a standard deviation of $ 800. Suppose that the interval is calculated to be (11693 comma 12827 ). How could the sample size and the confidence coefficient be altered in order to guarantee a decrease in the width of the interval?
Answers
Answer:
If we want to guarantee a decrease in the width of the confidence interval we need to analyze the margin of error given by:
[tex] ME = t_{\alpha/2} \frac{s}{\sqrt{n}}[/tex]
The width of the confidence interval is just defined as two times the margin of error:
[tex] Width = 2ME[/tex]
And then we can decrease this width of the interval we need to increase the sample size in order to have a greater number in the denominator for the margin of error and that implies a reduction in this width for the confidence interval at the confidence level fixed of 99%
By the other hand if we increase the confidence level then the width would be larger and in the other case when we decrease the confidence level the width would be lower.
Step-by-step explanation:
For this case w ehave the following info given from the problem
[tex] n =17[/tex] represent the sample size for the cars selected
[tex]\bar X = 12260[/tex] represent the average price for the cars sold
[tex] s= 800[/tex] represent the standard deviation for the solds
And we have a 99% confidence interval for the true average price for the cars given:
[tex]11693 \leq \mu \leq 12827[/tex]
And we know that the confidence interval for the true mean is given by this formula:
[tex] \bar X \pm t_{\alpha/2} \frac{s}{\sqrt{n}}[/tex]
If we want to guarantee a decrease in the width of the confidence interval we need to analyze the margin of error given by:
[tex] ME = t_{\alpha/2} \frac{s}{\sqrt{n}}[/tex]
The width of the confidence interval is just defined as two times the margin of error:
[tex] Width = 2ME[/tex]
And then we can decrease this width of the interval we need to increase the sample size in order to have a greater number in the denominator for the margin of error and that implies a reduction in this width for the confidence interval at the confidence level fixed of 99%.
By the other hand if we increase the confidence level then the width would be larger and in the other case when we decrease the confidence level the width would be lower.

A company issues 7% bonds with a par value of $200,000 at par on January 1. The market rate on the date of issuance was 6%. The bonds pay interest semiannually on January 1 and July 1. The cash paid on July 1 to the bond holder(s) is:
Answers
Answer:
The cash paid to the bondholder on July 1 is Z = $7000
Step-by-step explanation:
From the question we are told that
The percentage bond issued by the company is [tex]n = 7[/tex]%
The par value of the bond is [tex]V =[/tex]$200,000
The market rate is [tex]r = 6[/tex]%
So we are told that the bonds pay interest semiannually on January 1 and July
So the cash paid to the bondholder on July 1 is mathematically evaluated as
Z = [tex]V * \frac{7}{100} * \frac{1}{2}[/tex]
substituting value
Z = [tex]200000 * \frac{7}{100} * \frac{1}{2}[/tex]
Z = $7000
Final answer:
The cash paid on July 1 to bondholders for the company's 7% bonds with a par value of $200,000 is $7,000. This is calculated by first determining the annual interest payment and then dividing by two for the semiannual payment.
Explanation:
Understanding Bond Interest Payments
The question revolves around how much cash is paid to bondholders on July 1 for a company that issued 7% bonds with a par value of $200,000 at par when the market rate was 6%. Since the bonds were issued at par, this implies that the bond's stated interest rate matches the market interest rate at the time of issuance. However, the market rate later does not affect the fixed payments of a bond issued at par.
The interest payment for this bond would be calculated using the face value and the stated annual interest rate, which is then divided by two since interest is paid semiannually. The calculation is as follows:
Calculate the annual interest payment: $200,000 (par value) × 7% (interest rate) = $14,000.Divide the annual interest by two for the semiannual payment: $14,000 ÷ 2 = $7,000.Therefore, the cash paid on July 1 to the bond holder(s) is $7,000.

Answer:
64
Step-by-step explanation:
16 *4 is 64 so 64 divide by -4 equals -16.
Hope this helps.
Answer: 64
Step-by-step explanation: Since x is being divided by -4, to solve for x, multiply both sides of the equation by -4.
On the left side, the -4's will cancel
and on the right side, -16(-4) is 64.
So x = 64.

A major building contractor has 10 new floor plans that she would like to start using in the homes she builds. She wants to know whether her homes will sell for a higher price in the city or the suburbs. She builds two homes—one in the city and one in the suburbs—for each of the 10 floor plans. She uses the same real estate agency to sell all 20 homes and then she calculates the difference in selling price (city – suburb) for each of the floor plans. What is the most appropriate test to analyze her data? a. Two Proportion Z Test b. One Sample T Test c. One Proportion Z Test d. Independent Samples T Test e. Paired T Test
Answers
Answer: d. Independent Samples T Test
Step-by-step explanation: Independent Samples T Test is commonly used when you want to compare the means of two independent groups and determine if there is evidence that the the associated means are significantly different.
For this test, the data must have: continuous dependent variable; independent variable is categorical (two or more groups); cases that have values on both variables; the obervations are independent, i.e. the groups don't interfere on each other; random sample of data for the population; normal distribution of the dependent variable for each group; homogeneity of variances and no outliers.
Each groups should have at least 6 subjects and have the same number of individuals in each group.
The hypothesis in this test can be expressed as:
H₀: μ1 = μ2 or μ1 - μ2 = 0
H₁: μ1 ≠ μ2 or μ1 - μ2 ≠ 0
