suppose the actual number of sandwiches sold today was 41 describe the number of sandwiches sold as a percent increase or decrease
The number of sandwiches sold as a percent decrease can be described as 8.89% decrease.
Given that,
Number of sandwiches sold yesterday = 45
Number of sandwiches sold today = 41
It is clear that the number of sandwiches sold has been decreased.
So there will be a percent decrease.
Percent decrease = (original value - New value) / original value
= (45 - 41) / 45
= 0.0889
= 8.89%
Hence the percent decrease is 8.89%.

Mickey and Minnie Mouse are purchasing a new home. Their annual property taxes are estimated to be $5,467, and their homeowner's insurance policy has an annual cost of $1,440. They must also purchase flood insurance, since they live in below sea level, at an additional cost of $1,262 per year. How much will they be required to put into their escrow account each month to cover these costs?
Result:
Mickey and Minnie Mouse will need to put $680.75 into their escrow account each month to cover the property taxes, homeowner's insurance, and flood insurance costs.
What is an escrow account?An escrow account is like a savings account that is managed by a mortgage servicer. The portion deposited into an escrow account usually covers estimated property taxes and your homeowners and mortgage insurance premiums.
To calculate the monthly amount Mickey and Minnie Mouse need to put into their escrow account for property taxes, homeowner's insurance, and flood insurance, we will first add up the total annual costs for these expenses:
Property taxes: $5,467
Homeowner's insurance: $1,440
Flood insurance: $1,262
Total annual costs = $5,467 + $1,440 + $1,262 = $8,169
Next, we divide the total annual costs by 12 to get the monthly escrow amount:
$8,169 / 12 = $680.75
Therefore, $680.75 is the amount they will need to put into their escrow account each month.

What is the exact value of tan(sin−1(−12))cos(tan−1(1))?
Enter your answer, as a simplified fraction, in the box.
The exact value of trigonometrical identity [tan{sin⁻¹(-1/2)]/[cos{tan⁻¹(1)}] is -(√2/√3).
Given that the trigonometrical identity is [tan{sin⁻¹(-1/2)]/[cos{tan⁻¹(1)}].
In order to solve the expression:
The known values are:
sin⁻¹(-1/2) = -π/6
tan⁻¹(1) = π/4
Now we can substitute these values into the expression:
[tan{sin⁻¹(-1/2)]/[cos{tan⁻¹(1)}] = [tan(-π/6)]/[cos(π/4)]
Using the fact that tan(-x) = -tan(x) and cos(π/4) = sin(π/4) = √2/2, we can simplify:
[tan{sin⁻¹(-1/2)]/[cos{tan⁻¹(1)}] = -tan(π/6)/[√2/2]
Using the fact that tan(π/6) = 1/√3, we can simplify further:
[tan{sin⁻¹(-1/2)]/[cos{tan⁻¹(1)}] = -[1/√3]/[√2/2]
[tan{sin⁻¹(-1/2)]/[cos{tan⁻¹(1)}] = -(√2/√3).

Suppose that you are conducting a study on the effectiveness of a new teaching method and that you wish to use a hypothesis test to support your claim regarding the mean test score under this method. What restrictions are there in the wording of the claim? Will your claim become the null hypothesis or the alternative hypothesis, or does it depend on the situation? Give an example of a claim which is incorrectly worded.
Answer & Step-by-step explanation:
In hypothesis testing, the claim being made is called the alternative hypothesis. The null hypothesis is the opposing statement, and it is presumed to be true until sufficient evidence suggests otherwise. The wording of the claim must be specific and precise, and one must clearly state the population, the parameter of interest, and the direction of the hypothesis test (i.e., one-tailed or two-tailed).
For example, a well-worded alternative hypothesis might be "The new teaching method will result in a higher mean test score for students than the traditional teaching method." In this case, the null hypothesis would be "The new teaching method will not result in a higher mean test score for students than the traditional teaching method."
An incorrectly worded claim might be "The new teaching method is better than the traditional teaching method." This claim is too vague because it does not specify in what way the new method is better, nor does it give a direction for the hypothesis test.
In summary, when conducting a hypothesis test to support a claim regarding the mean test score under a new teaching method, the wording of the claim must be specific and precise, and the claim will become the alternative hypothesis.

In a survey, 23 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $33 and standard deviation of $13. Construct a confidence interval at a 95% confidence level.
we can say with 95% confidence that the population mean of how much people spend on their child's last birthday gift is between $27.31 and $38.69.
What is confidence interval?
A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with more variability.
Since we want a 95% confidence interval, the level of significance (α) is 0.05/2 = 0.025. We can use a t-distribution table to find the t-score that corresponds to this level of significance and the degrees of freedom (df) = n - 1 = 23 - 1 = 22.
From the t-distribution table, the t-score with 22 degrees of freedom and a 0.025 level of significance is approximately 2.074.
Now we can plug in the values and calculate the confidence interval:
CI = 33 ± 2.074*(13/√23)
= 33 ± 5.693
= (27.307, 38.693)
Therefore, we can say with 95% confidence that the population mean of how much people spend on their child's last birthday gift is between $27.31 and $38.69.

2. Increasing the minimum wage has not traditionally caused massive unemployment though traditional economists have argued that it should. Why have changes to minimum wage not affected unemployment too much?
3. The US has one of the lowest federal minimum wages compared to other developed nations. Can you think of reasons why this might be?
4. The real minimum wage has fallen over time with the rise of inflation. This represents less purchasing power for minimum wage workers. Are you ok with that? Why or why not? How many people actually earn at or near minimum wage?
Despite traditional economic theory suggesting that an increase in the minimum wage should lead to unemployment, the actual impact on employment has been more nuanced. Empirical evidence suggests that moderate increases in the minimum wage have not led to massive job losses, but rather have resulted in small increases in labor costs that are offset by increased productivity and reduced employee turnover. Additionally, higher wages can increase consumer spending, leading to an increase in demand for goods and services, which can ultimately create more jobs.
There are several reasons why the federal minimum wage in the US is lower than in other developed countries. One reason is the political climate in the US, where there is often resistance to government intervention in the labor market. Additionally, many US states have their own minimum wage laws, which can be higher than the federal minimum wage. Finally, the US has a large low-skilled immigrant workforce, which can put downward pressure on wages.
I am not okay with the real minimum wage falling over time with the rise of inflation. Inflation erodes the purchasing power of workers, making it difficult for them to make ends meet. This can lead to increased financial hardship, which can have negative effects on individuals and families. Furthermore, the minimum wage was originally designed to ensure that workers earn a living wage, which is a basic necessity for a decent standard of living. As such, it is important that the minimum wage keep pace with inflation.
According to the Bureau of Labor Statistics, in 2021, about 1.9 million workers in the US earned at or below the federal minimum wage of $7.25 per hour. However, many more workers earn slightly above the minimum wage, and an increase in the minimum wage could potentially raise wages for those workers as well. Additionally, many states have higher minimum wage rates than the federal minimum wage, which means that the number of workers affected by changes to the minimum wage will vary depending on the state.

A fair coin has been tossed a thousand times and the number of heads and tails recorded. Which of the following statements describes a more likely outcome (as compared to the others)? Explain/justify your answer.
A: The number of tails is 601 and the number of heads is 399.
B: 47% of the tosses were heads.
C: There were 20 more heads tossed than tails
since the coin is fair the probability of it being heads or tails is exactly 50%. and the experimental probability should be as close as possible to 50% so we immedietly know answer A is wrong since the difference between 601 and 399 is too big. now we have to see if B or C is closer to 50%. to do that we turn C into a percentage and since there were 1000 tosses 10 tosses are 1%. and since there was a difference of 20 tosses in C the difference was 2% in C. and for B we know the experimental probability of heads was 47% and the probability of tails was 53% so the difference for B is 6%. And since 2% is less than 6% the answer C is the most correct. also pls mark as brainliest answer

What is the polar form of -2√3-6i?
The polar form of the complex number -2√3 - 6i is r , θ = (2√24 , 60°)
How to find the polar form of the complex number?The polar form of a complex number is given by r = x + iy is r , θ where r = √(x² + y²) and θ = tan⁻¹y/x
So, to find the polar form of the complex number, -2√3 - 6i we proceed as follows. -2√3 - 6i
Since r = x + iy where
x = -2√3 and y = -6So, substituting the values of the variables into the equation, we have that the magnitude r = √(x² + y²)
= √((-2√3)² + ( -6)²)
= √(4 × 3 + 36)
= √(12 + 36)
= √48
= √(24 × 4)
= 2√24
The angle θ = tan⁻¹y/x where
y = - 6 and x = -2√3So, substituting the values of the variables into the equation, we have that
θ = tan⁻¹y/x
= tan⁻¹(-6/-2√3)
= tan⁻¹(3/√3 × √3/√3)
= tan⁻¹(3√3/(√3 × √3)]
= tan⁻¹(3√3/3]

Given the line 2x + 3y=6
(i) make the subject of the formula of 2x + 3y= 6
(ii) find the gradient of the line
(iii) find the coordinates of the point at which the line cuts the x-axis.
Answer:
(i) To make 2x + 3y = 6 the subject of the formula, we need to isolate y on one side of the equation. We can do this by subtracting 2x from both sides of the equation:
2x + 3y = 6
3y = 6 - 2x
y = (6 - 2x)/3
Therefore, the subject of the formula is y = (6 - 2x)/3.
(ii) The gradient of the line can be found by rearranging the equation into slope-intercept form, y = mx + b, where m is the gradient of the line.
2x + 3y = 6
3y = -2x + 6
y = (-2/3)x + 2
Comparing this to the slope-intercept form, we see that the gradient of the line is -2/3.
(iii) To find the coordinates of the point at which the line cuts the x-axis, we need to set y = 0 in the equation of the line and solve for x:
y = (-2/3)x + 2
0 = (-2/3)x + 2
2/3x = 2
x = 3
Therefore, the point at which the line cuts the x-axis has coordinates (3, 0).
