Answer:

71° and 71°

Step-by-step explanation:

This is isosceles triangle.

So,

\(38 + x + x = 180 \)

\(38 + 2x = 180\)

\(2x = 180 - 38\)

\(2x = 142\)

\(x = 142 \div 2\)

\(x = 71\)

Answer:

c = 202 children use the pool, and 284 - 202, or 82 adults.

Step-by-step explanation:

Represent the number of children by c and the number of adults by a.

There are a total of 284 people using the pool, so c + a = 284.

Admission fees are $1.50/child and $2.00/adult.  $1.50c is the amount taken in through ticket sales for c children;  $2.00a for adults.

Then total ticket sales are ($1.50/child)c + ($2.00/adult)a = $467.

Going back to c + a = 284, a = 284 - c, and so the above equation becomes

($1.50/child)c + ($2.00/adult)(284 - c) = $467

After simplifying this equation in c, we get:

1.50c + 568 - 2c = 467, or

101 = 0.5c.  Thus, c = 202 children use the pool, and 284 - 202, or 82 adults.

It is possible to reach all five buildings without walking down any sidewalk more than once, even if there are no sidewalks between pairs of adjacent buildings.

In this case, since there are five buildings arranged around the edge of a circular courtyard, we can consider a path that starts from any building and moves to the next building counterclockwise. By following this path, we can visit each building exactly once without having to walk down any sidewalk more than once.

To visualize this, imagine standing at one of the buildings and facing the courtyard. From that position, you can choose to move to the building on your left. Then, from that building, you can again choose to move to the building on your left. By continuing this pattern, you will eventually visit all five buildings, forming a loop around the courtyard, without repeating any sidewalk.

Therefore, it is possible to reach all five buildings without walking down any sidewalk more than once, even if there are no sidewalks between pairs of adjacent buildings.

Answer:

\(m = -3\)

Step-by-step explanation:

-To determine the slope of the red line on the graph, you need the slope formula:

\(m = \frac{y_{2} - y_{1}}{x_{2}- x_{1}}\)

-Since the red line shows it's decreasing, then the number will be negative.  So, l picked \((0,3)\) and \((1,0)\) for the slope formula:

\(m = \frac{0 - 3}{1 - 0}\)

Then, solve:

\(m = \frac{0 - 3}{1 - 0}\)

\(m = \frac{-3}{1}\)

\(m = -3\)

so, the slope is \(-3\).

Answer:

9 and 11

Step-by-step explanation:

there is a difference of 2 between consecutive odd integers.

let n and n + 2 be the integers , then

n + n + 2 = 20

2n + 2 = 20 ( subtract 2 from both sides )

2n = 18 ( divide both sides by 2 )

n = 9

and n + 2 = 9 + 2 = 11

the two consecutive odd numbers are 9 and 11

We can utilise the five triangles in the provided heptagon and the characteristics of triangles to demonstrate that the total interior angle of a heptagon is 900 degrees.

A triangle's internal angles are always added up to 180 degrees. The inner angles of the five triangles that make up the heptagon add up to 5 * 180, or 900 degrees.

The total of the interior angles of the heptagon can be calculated using the five triangles that make up the shape. We can see that the sum of the interior angles of the heptagon equals the sum of the angles of the five triangles because the angles of the heptagon are labelled.

Moving Average and Exponential Smoothing is a method used in a forecasting model for a time series when a trend, seasonal, or cyclical effect is not significant.

When trend, seasonal, or cyclical effects are not significant in a time series, the most appropriate method for forecasting is typically the Moving Average or Exponential Smoothing method. The Moving Average method involves calculating the average of a set of previous observations to forecast the next data point.

The number of previous observations to include in the average is determined by the chosen window size, which can be adjusted based on the level of smoothing desired. On the other hand, the Exponential Smoothing method assigns more weight to recent observations and less weight to older observations. This method assumes that recent data points are more relevant for forecasting future values than older data points.

The level of smoothing can be controlled by adjusting the smoothing parameter. Linear regression and Holt-Winters methods are better suited for time series with significant trends, and seasonal, or cyclical effects. Holt-Winters is a more complex method that considers both trend and seasonal effects in addition to the level of smoothing.

Step-by-step explanation:

The amount received by Ricky in his account by the time of his retirement at 1% interest rate compounded monthly is equals to the $154,937.8.

Age of Ricky at present is 35 years and he plans to retire in age of 63 years.

Monthly deposits, PMT = $400

Interest rate = 1%

Monthly interest rate, \(r = \frac{0.01}{12}\) = 0.00083

number of years = 63 years - 35 years

= 28 yrs.

Number of time periods, n = 28 years × 12 = 336 months

Using the amount received formula, Amount received = \( PMT(\frac{ ( 1 + r)^n - 1}{r})\)

where, PMT --> present monthly deposit

r --> interest rate here monthly interest rate

Substitute all known values in above formula, Amount received= \(400 (\frac{(1 +0.00083)^{336}- 1}{ 0.00083})\) = $154,937.7680.

Hence, required value is $154,937.8.

If demand or annual usage increases by 10 percent, the Economic Order Quantity (EOQ) will increase. The EOQ model is used in inventory management to determine the optimal order quantity that minimizes total inventory costs.

The Economic Order Quantity (EOQ) is a model used in inventory management to determine the optimal order quantity that minimizes total inventory costs. It takes into account factors such as demand, holding costs, and ordering costs. When demand or annual usage increases by 10 percent, it means that more units are being consumed or sold within a given time period.

With an increase in demand, the EOQ will also increase. This is because the EOQ formula takes into consideration the trade-off between holding costs and ordering costs. Holding costs are the costs associated with holding inventory, such as warehousing and insurance, while ordering costs are the costs incurred when placing an order, such as administrative and transportation costs.

When demand increases, more units need to be ordered to meet the higher demand. This results in an increase in ordering costs, as more frequent orders will need to be placed. Consequently, the EOQ will increase to find the new optimal order quantity that balances the increased ordering costs with the holding costs.

In summary, if demand or annual usage increases by 10 percent, the EOQ will increase due to the need to order more frequently to meet the higher demand, resulting in increased ordering costs. This adjustment ensures that the inventory management system remains efficient and cost-effective.

Based on both the p-value method and the critical value method, we fail to reject the null hypothesis and cannot infer that the two groups differ in the mean number of pictures printed.

To determine if the two groups (digital camera owners and standard camera owners) differ in the mean number of pictures printed, we can conduct a hypothesis test using both the p-value method and the critical value method.

Let's define our hypotheses:

Null Hypothesis (\(H_0\)): The mean number of pictures printed is the same for both groups.

Alternative Hypothesis (\(H_1\)): The mean number of pictures printed differs between the two groups.

We'll use a significance level of 0.05 (5%).

First, let's calculate the test statistic for the two-sample t-test using the provided summary statistics:

Digital:

Mean = 18.25

Standard Deviation = 6.5

Sample Size = 8

Standard:

Mean = 16.5

Standard Deviation = 19.2

Sample Size = 8

Using the formula for the two-sample t-test, the test statistic (t) is given by:

\(t = (mean_1 - mean_2) / \sqrt{(s_1^2/n_1) + (s_2^2/n_2)}\)

Substituting the values, we have:

\(t = (18.25 - 16.5) / \sqrt{(6.5^2/8) + (19.2^2/8)}\)

t ≈ 0.75

Now, let's perform the hypothesis test using both methods:

1) P-value Method:

Using the t-distribution with \((n_1 + n_2 - 2)\) degrees of freedom, we can calculate the p-value associated with the test statistic.

The p-value is the probability of observing a test statistic as extreme as the one calculated, assuming the null hypothesis is true.

Using a t-table or statistical software, we find that the p-value corresponding to t ≈ 0.75 is approximately 0.47.

Since the p-value (0.47) is greater than the significance level (0.05), we fail to reject the null hypothesis. There is not enough evidence to conclude that the mean number of pictures printed differs between the two groups.

2) Critical Value Method:

Using the t-distribution with \((n_1 + n_2 - 2)\) degrees of freedom and a significance level of 0.05, we can find the critical value.

The critical value is the value beyond which we would reject the null hypothesis.

For a two-tailed test at a 5% significance level and 14 degrees of freedom (8 + 8 - 2), the critical value is approximately ±2.145.

Since the test statistic (0.75) does not exceed the critical value (±2.145), we fail to reject the null hypothesis. There is not enough evidence to conclude that the mean number of pictures printed differs between the two groups.

In conclusion, based on both the p-value method and the critical value method, we do not have sufficient evidence to infer that the two groups differ in the mean number of pictures printed.

The type of error that could have occurred in this scenario is a Type II error. A Type II error occurs when the null hypothesis is not rejected, even though it is false.

In this case, the null hypothesis is that the proportion of defective bulbs in the shipment is greater than or equal to 5%. By not rejecting this null hypothesis, the company is accepting the possibility that the shipment has a high proportion of defective bulbs, when in reality it does not.

The change in the nominal exchange rate, in Canada's perspective, is a depreciation of the Canadian dollar by 2.76%.

Nominal exchange rate is the price of one currency in terms of another currency. It represents the number of units of one currency that can be purchased with a single unit of another currency. In Canada's perspective, a change in nominal exchange rate means the value of the Canadian dollar in US dollars. So, to calculate the change in nominal exchange rate from Canada's perspective.

Nominal Exchange Rate = Real Exchange Rate x (1 + Inflation of Canada) / (1 + Inflation of US) Given, Real Exchange Rate of Canada

= 4.9% Inflation of Canada

= 8.5% Inflation of US

= 3.8%  Nominal Exchange Rate

= 4.9% x (1 + 8.5%) / (1 + 3.8%) Nominal Exchange Rate

= 4.9% x 1.085 / 1.038 Nominal Exchange Rate

= 5.3099 / 1.038 Nominal Exchange Rate

= 5.11 (rounded to two decimal places)

This means that if there were no inflation, the nominal exchange rate from Canada's perspective would have been 5.11 Canadian dollars per US dollar. But due to inflation, the Canadian dollar depreciated by 2.76% (calculated as (5.11 - 4.97) / 5.11 x 100%). Therefore, the change in the nominal exchange rate, in Canada's perspective, is a depreciation of the Canadian dollar by 2.76%.
