7.) Jessica took her parents out to dinner. The total
bill was $48.55. She left an 18% tip. What was
Jessica's total cost for dinner?

Answers

Answer 1
57.29 you do 48.55 times .18 which =8.74 then add the tip with the initial cost 8.74+48.55 =57.29 to get your answer 57.29
Answer 2

Answer:

$57.289

Step-by-step explanation:

18% of 48.55

48.55 × 18 ÷ 100

= 8.739

48.55 + 8.739

=$57.289

24.1 let fn(x) = 1 2 cos2 √ nx n . prove carefully that (fn) converges uniformly to 0 on r.

Answers

We need to prove that the sequence of functions fn(x) = (1/2)cos^2(√nx) converges uniformly to 0 on the real numbers.

To prove uniform convergence, we need to show that for any ε > 0, there exists a positive integer N such that |fn(x) - 0| < ε for all n > N and for all x in the real numbers.

Given fn(x) = (1/2)cos^2(√nx), we observe that as n increases, the argument √nx inside the cosine function becomes larger, causing the cosine to oscillate more rapidly between 0 and 1. Since we are multiplying the cosine by (1/2) and taking its square, fn(x) gradually approaches 0 as n increases.

To formally prove uniform convergence, we can start by fixing ε > 0 and then choose N such that √Nx > 1/ε. By selecting this N, we can show that for all n > N, |fn(x) - 0| < ε for any x in the real numbers. This demonstrates that the sequence of functions fn(x) converges uniformly to 0 on the real numbers.

Answers

The confidence interval estimate of the population mean is (0.37, 0.75). The correct option is B No. Based on the confidence interval, it is not possible to say that the mean mercury level in tuna sushi is greater than 1 ppm.

How to explain the information

The confidence interval includes 1 ppm, so the true mean could be 1 ppm or less. Additionally, at least one of the sample values is less than 1 ppm, so at least some of the fish are safe.

The sample standard deviation is calculated by finding the square root of the sum of the squared deviations from the mean for each value in the sample. The sample size is the number of values in the sample.

Confidence interval = sample mean ± 1.645 * (sample standard deviation / ✓(sample size))

Confidence interval = 0.51 ± 1.645 * (0.24 / ✓(7))

= (0.37, 0.75)

As you can see, the confidence interval includes 1 ppm, so the true mean could be 1 ppm or less.

b. Use the frequency distribution on the previous page to construct a histogram for these data.

Answers

To analyze the motor fuel octane ratings data, we can start by constructing a frequency distribution and then use it to create a histogram.

The frequency distribution will provide information about the distribution of the data across different octane rating ranges, while the histogram visually represents the distribution graphically.

a. To construct a frequency distribution, we divide the data into bins and count the frequency of values falling within each bin. In this case, we will use 8 bins. We determine the lower and upper limits for each bin and calculate the midpoint by averaging the limits. Then, we count the number of values within each bin and calculate the relative frequency by dividing the frequency by the total number of values.

b. Once the frequency distribution is constructed, we can use it to create a histogram. The histogram represents the frequency or relative frequency of values within each bin as vertical bars. The bins are plotted along the x-axis, and the height of the bars represents the frequency or relative frequency on the y-axis. The histogram allows us to visualize the distribution pattern of the motor fuel octane ratings data, showing if it is skewed, symmetric, or has other characteristics.

By constructing a frequency distribution and creating a histogram, we can gain insights into the distribution of the motor fuel octane ratings data. The frequency distribution table provides a summarized view of how the data is spread across different octane rating ranges, while the histogram visually represents the same information in a graphical form. Both the frequency distribution and the histogram aid in understanding the distribution pattern, identifying potential outliers or gaps, and informing further analysis or decision-making related to the data.

a local ice cream shop has a special deal on thursdays: buy a waffle cone for $3 and get each scoop of ice cream for $1.50. what would be the rate of change in this word problem?

Answers

In the given word problem, the rate of change is the change in the cost of the ice cream concerning the change in the number of scoops.

That is, the rate of change is the ratio of the change in the cost of ice cream and the change in the number of scoops. Let's first calculate the initial rate of change or slope of the given deal: When we buy a waffle cone, the cost is $3, and we can buy one scoop of ice cream for $1.50.So, for one scoop of ice cream, the total cost would be 3 + 1.50 = $4.50.

We can represent the cost of one scoop of ice cream with the help of a linear equation: y = mx + b. Here, the slope or the rate of change, m = Change in cost of ice cream/ Change in the number of scoops= 1.5/1= 1.5Therefore, the rate of change of the ice cream with respect to the number of scoops is $1.50/scoop.

Consider the curve defined by the equation y = 47° +10x. Set up an integral that represents the length of curve from the point (-3,6) to the point (2,36).

Answers

The integral that represents the length of the curve from the point (-3,6) to the point (2,36) is L = ∫[-3 to 2] √101 dx.

To find the length of the curve defined by the equation y = 47° + 10x from the point (-3,6) to the point (2,36), we can use the arc length formula for a curve:

L = ∫[a to b] √(1 + (dy/dx)^2) dx

First, let's find dy/dx by taking the derivative of the given equation:

dy/dx = d/dx(47° + 10x) = 10

Now we can substitute this value into the arc length formula:

L = ∫[-3 to 2] √(1 + (10)^2) dx

Simplifying:

L = ∫[-3 to 2] √(1 + 100) dx

L = ∫[-3 to 2] √101 dx

Thus, the integral that represents the length of the curve from the point (-3,6) to the point (2,36) is:

L = ∫[-3 to 2] √101 dx

Answers

The sample mean of the given data series is 33.7 and the population mean is 35.86. The difference between the two quantities, rounded to two decimal places, is -2.16.

Sample mean and population mean are important terms in statistics. The sample mean is the average of a set of data taken from a larger population, while the population mean is the average of an entire population.

To find the sample mean of the given data series, we add up all the values and divide by the total number of values. Therefore,

Sample mean = (15+26+25+23+26+28+20+20+31+45+32+41+54+23+45+24+90+19+16+75+29) / 21
Sample mean = 33.7

To find the population mean, we use the same formula but with all the values of the population included. Therefore,

Population mean = (15+26+25+23+26+28+20+20+31+45+32+41+54+23+45+24+90+19+100+75+29) / 21
Population mean = 35.86

Finally, to find the difference between the two quantities, we subtract the sample mean from the population mean. Therefore,

Difference = Population mean - Sample mean
Difference = 35.86 - 33.7
Difference = -2.16 (rounded to two decimal places)

Therefore, the difference between the sample mean and population mean is -2.16.

Use the Singapore Bar Method, including drawings, to solve the following problem. Identify the unit value when appropriate, including labels. The sides of the triangle are in the ratio 5:7:8 and the longest side is 36 cm longer than the shortest side. Find the perimeter of the triangle.

Answers

When the sides of the triangle are in the ratio 5:7:8 and the longest side is 36 cm longer than the shortest side, the perimeter is 240cm.

How to calculate the perimeter

Let's assume the shortest side of the triangle has a length of x cm. According to the given ratio, the sides of the triangle are in the ratio 5:7:8. Therefore, the lengths of the sides can be expressed as:

Shortest side: 5x

Second side: 7x

Longest side: 8x

We are also given that the longest side is 36 cm longer than the shortest side. So we can set up the following equation:

8x = 5x + 36

Now, let's solve this equation to find the value of x:

8x - 5x = 36

3x = 36

x = 36 / 3

x = 12

Now we can substitute this value back into the expressions for the side lengths to find their actual lengths:

Shortest side: 5x = 5 * 12 = 60 cm

Second side: 7x = 7 * 12 = 84 cm

Longest side: 8x = 8 * 12 = 96 cm

Finally, we can calculate the perimeter of the triangle by adding the lengths of all three sides:

Perimeter = Shortest side + Second side + Longest side

= 60 cm + 84 cm + 96 cm

= 240 cm

Therefore, the perimeter of the triangle is 240 cm.
