The value of \(z_{\alpha /2}\) that corresponds to a 90% confidence interval is

The confidence level is the likelihood that, if you repeat your experiment or resample the population in the same manner, you will come close to arriving at the same estimate.

The estimate's upper and lower bounds are what make up the confidence interval for a particular level of confidence.

For 90%confidence interval = 0.9

significance level, α = 1 - 0.9 = 0.10

For two tailed test, α/2 = 0.05

using z table

0.0505 = -1.64

0.05 = x

0.0495 = -1.65

solving for x by interpolation

(0.0505 - 0.05) / (0.05 - 0.0495) = (-1.64 - x) / (x - -1.65)

0.0005(x + 1.65) = 0.0005(-1.64 - x)

x + x = -1.64 - 1.65

x = -1.645

from z tables at 90% confidence interval in two tailed test the score is found to be 1.645

The marginal revenue in the interval between six and seven jet skis is $300.

Here we are given that total revenue from six jet skis is $2,400

and total revenue from seven jet skis is $2,700

Now, marginal revenue is defined as the revenue gained or lost by producing one more additional unit of a good.

Here, the total revenue increases from $2,400 to $2,700 as we go from producing 6 jet skis to 7 jet skis.

Thus, the change in total revenue will be-

2700 - 2400

= 300

This means that the gain in revenue is $300.

Thus, the marginal revenue in the interval between six and seven jet skis is $300.

\(\large \mathfrak{Solution : }\)

let's solve for y :

value of y = 5

Answer:

\(y=5\)

Step-by-step explanation:

\(4y=38-\frac{1}{2}\left(4y+16\right)\)

→ Multiply fractions:- \(a\times\frac{b}{c} =\frac{a\times b}{c}\)

\(\frac{1\cdot \left(4y+16\right)}{2}\)

\((4y+16)=4y+16\)

\(4y=38-\frac{4y+16}{2}\)

→ Multiply both sides by 2:-

\(y\cdot \:2=38\cdot \:2-\frac{4y+16}{2}\cdot \:2\)

\(8y=76-\left(4y+16\right)\)

\(76-(4y+16)=-4x+60\)

\(8y=-4y+60\)

→ Add 4y to both sides:-

\(8y+4y=-4y+60+4y\)

\(12y=60\)

→ Now, divide both sides by 12:-

\(\frac{12y}{12}=\frac{60}{12}\)

\(y=5\)

According to the question Joe's hypothesis can be stated as follows H0: μ ≤ 568 (Null hypothesis) , H1: μ > 568 (Alternative hypothesis)

Joe's hypothesis can be stated as follows H0: The population mean (μ) of the elite school students is less than or equal to 568. H1: The population mean (μ) of the elite school students is greater than 568.To test this hypothesis, Joe would typically collect a sample from the elite school students and calculate the sample mean.

He can then compare this sample mean to the hypothesized population mean of 568. If the sample mean is significantly higher than 568, Joe would have evidence to support his hypothesis that the elite school students score higher than the general population.

To make a conclusive decision, Joe would perform a statistical test, such as a t-test or z-test, and calculate the p-value associated with the observed sample mean. If the p-value is below a predetermined significance level (e.g., 0.05), Joe can reject the null hypothesis and conclude that the elite school students score higher than the general population.

Germany and the US are sending tanks to Ukraine as a show of support for the government in Kyiv, with Germany sending 14 Leopard 2 tanks & the US delivering 31 Abrams in the coming months.

The rationale behind this military aid is to demonstrate solidarity with Ukraine in its ongoing conflict with Russia & to bolster its military capabilities in the face of aggression. This move is seen as a signal to Russia that the international community will not tolerate further military incursions into Ukrainian territory and is committed to supporting Ukraine's sovereignty & territorial integrity. It is also hoped that this aid will help stabilize the situation in Ukraine and bring about a peaceful resolution to the conflict.

The confidence intervals for Bugs Bunny and Baby Shark are [32.3%, 35.7%] and [24.7%, 27.3%] respectively, with a margin of error of 5%. Since these intervals overlap, one cannot say with certainty that more people clearly support Bugs Bunny over Baby Shark in the population based on the poll results. Further research or a larger sample size would be needed to determine the true support for each candidate.

In a heated election, people will vote for their all-time favorite cartoon. Before the election, a poll was taken to see the results and it showed that 34% of the people said they will vote for Bugs Bunny, and 26% said they will vote for Baby Shark.

Answer:

Joe's age = 25 years

Mary's age =  50 years

Bob's age   = 10 years

Step-by-step explanation:

Joe's age = x years

Mary's age = 2*x = 2x

Bob's age = x - 15

Sum of their ages = 85

x + 2x + x - 15 = 85

Combine like terms,

4x - 15 = 85

Add 15  to both sides

4x - 15 + 15 = 85 + 15

4x = 100

Divide both sides by 4

x = 100/4

x = 25

Joe's age = 25 years

Mary's age = 2*25 = 50 years

Bob's age = 25 - 15 = 10 years

Let Joe's age be x

Let Bob's age be x-15

Let Mary's age be 2x

\( \mathcal{Bob's \: age+ Joe's \: age+ Mary's \: age = 85}\)

Substitute the values we just gave ATQ

\( \sf \: x - 15 + x + 2x = 85 \\ \sf \: 4x - 15 = 85 \\ \sf \: 4x = 85 + 15 \\ \sf \: 4x = 100 \\ \sf \: x = 25\)

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies follows an approximately normal distribution with a mean and standard deviation that are not specified in the given information. We don't have the necessary information to calculate the percentile in this case.

However, we can still calculate the answer using the provided information. To find the number of chocolate chips more than 1225, we need to determine the z-score and find the corresponding area under the normal curve. The z-score formula is given by z = (x - μ) / σ, where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation. In this case, we don't know the mean and standard deviation, so we cannot calculate the exact z-score. However, we can still provide an explanation of the process. To find the z-score, we would subtract the mean from 1225 (the value we want to find the probability for) and divide the result by the standard deviation. Once we have the z-score, we can use a standard normal distribution table or a calculator to find the corresponding area. The area represents the probability of a random variable being less than or equal to the given value. Since we want the probability of having more than 1225 chocolate chips, we would subtract the obtained probability from 1. Regarding the second question, without knowing the mean and standard deviation, it is not possible to determine the exact percentile for a bag that contains 1000 chocolate chips. Percentiles represent the proportion of data points that fall below a certain value.

Answer:

7x+12y ≤ 600

7x+12y = 600

Step-by-step explanation:

Lets first call cars x and minivans y. Since they want to raise 600, you can do the sign ≤ and 600

≤ 600

Since it is $7 per car, we can do 7x.

Since it is $12 per minivan, we can do 12y.

Together, they have to add up to 600 or more.

7x+12y ≤ 600

If you provide some options, I might be able to give a better answer. Without options, I can't tell if they want an exact answer or not. So technically, the answer could also be:

Scenario: A small business owner needs to analyze their sales data to make informed decisions about pricing and profitability.

Supporting Detail 1: The concept of linear equations can be applied to determine the break-even point and set optimal pricing strategies for the business.

Worked Example 1: Let's say the small business sells a product for $10 each, and the fixed costs (expenses that don't vary with the number of units sold) amount to $500. The variable costs (expenses that depend on the number of units sold) are $2 per unit. We can use the formula for a linear cost equation (C = mx + b) to find the break-even point where revenue equals total costs:

10x = 2x + 500

Simplifying the equation, we get:

8x = 500

x = 500/8

x = 62.5

The break-even point is 62.5 units. Knowing this information, the business owner can make decisions about pricing, cost control, and production targets.

Supporting Detail 2: The concept of systems of equations can be applied to optimize the allocation of resources in the business.

Worked Example 2: Let's consider a scenario where the business owner sells two different products. Product A generates a profit of $5 per unit, while Product B generates a profit of $8 per unit. The business owner has a limited budget of $500 and wants to determine the optimal allocation of resources between the two products. We can set up a system of equations to represent the profit constraints:

x + y = 500 (total budget)

5x + 8y = P (total profit, represented as P)

By solving this system of equations, the business owner can find the optimal values of x and y that maximize the total profit while staying within the budget constraints.

Conclusion: Applying concepts from this algebra course to real-life scenarios, such as analyzing sales data for a small business, helps in understanding the material by providing practical applications. It demonstrates the relevance of algebra in making informed decisions, optimizing resources, and maximizing profitability.

These examples highlight how algebraic concepts enable problem-solving and provide valuable tools for individuals in various fields, including business and entrepreneurship.
