What is 20% of 350? Please explain

Bar charts, pie charts, and stacked bar charts are commonly used for representing quantitative data.

When it comes to visually representing quantitative data, several types of charts are commonly used. One such chart is the bar chart, which uses rectangular bars of varying lengths to depict numerical values. Bar charts are effective in comparing different categories or groups and showcasing trends over time. Another popular chart is the pie chart, which divides a circle into slices to represent different proportions or percentages of a whole. Pie charts are useful for illustrating the composition or distribution of a data set. Additionally, stacked bar charts are frequently employed to display multiple variables or categories within a single bar, where each segment represents a different subset. This type of chart allows for easy comparison of subcategories while maintaining an overall total. These three chart types - bar charts, pie charts, and stacked bar charts - offer versatile options for visualizing quantitative data, enabling effective communication and analysis.

Answer:

\(P(t)=100(0.994)^t\)

Step-by-step explanation:

A calculator shows the value of \(e^{-.006} \approx 0.994\) meaning that each day, about 99.4% of the sample remains.

The formula \(P(t)=100e^{-0.006t} = 100(e^{-0.006})^t=100(0.994)^t\)

Evaluate this at t = 16 to get 91 grams remain.

You would need a sample size of 384 in order to create a population proportion with a margin of error of no more than 0.025 and a 95% confidence interval.

In order to calculate the sample size needed for a 95% confidence interval with a margin of error of no more than 0.025, the formula to use is the following:

\(n = (z-score)^2 * p * (1-p) / (margin of error)^2\)

Where n = sample size, z-score = 1.96 (for 95% confidence interval), p = 0.5 (the expected population proportion) and margin of error = 0.025.

Substituting these values into the equation, we get:

\(n = (1.96)^2 * 0.5 * (1 - 0.5) / (0.025)^2\\n = 384\)

Therefore, you would need a sample size of 384 in order to create a population proportion with a margin of error of no more than 0.025 and a 95 %  confidence interval.

Thus, the experimental probability of a hurricane striking the city in at least 1 of the next 10 years is 89.3%.

To start, we need to find the probability that a hurricane will NOT strike Rob's city in any given year. We know that the probability of a hurricane striking in a year is 20%, so the probability of a hurricane NOT striking in a year is 80% (100% - 20% = 80%).

Using this information, we can calculate the probability of no hurricane striking in 10 consecutive years:

0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 x 0.8 = 0.107 (rounded to three decimal places)

So, the probability of NO hurricanes striking in 10 consecutive years is 10.7%.

To find the probability of at least one hurricane striking in the next 10 years, we can subtract the probability of no hurricanes from 1:

1 - 0.107 = 0.893 (rounded to three decimal places)

So, Rob's experimental probability that a hurricane will strike the city in at least 1 of the next 10 years is 0.893, or 89.3% (rounded to the nearest percent).

It's important to note that this is an experimental probability, based on a simulation that Rob performed. It may not be exactly the same as the theoretical probability, which is based on mathematical calculations. However, as long as Rob's simulation was conducted correctly and with enough data points, his experimental probability should be a good estimate of the true probability.

Rob's simulation aims to find the experimental probability of a hurricane striking his city in at least 1 of the next 10 years. With a 20% probability of a hurricane in any given year, the probability of no hurricane in a year is 80% (100%-20%). To calculate the probability of no hurricanes in the next 10 years, we can multiply the probability of no hurricane each year: 0.8^10 = 0.107.

The measure of angle 1 is given as follows:

m < 1 = 150º.

From the image given at the end of the answer, we have that two Railroad tracks are transversal to the Olive Street.

Considering that Olive Street is transversal to the parallel lines, we have that the angle 2 forms a linear pair with the angle of 30º.

Linear pairs are supplementary angles, meaning that the sum of their measures is of 180º, hence the measure of angle 2 is given as follows:

m < 2 + 30º = 180º

m < 2 = 180º - 30º

m < 2 = 150º.

Now we have that angles 1 and 2 are alternate interior angles, as they are between the two parallel lines, on the opposite side of the transversal.

Alternate interior angles are congruent, meaning that the measure of angle 1 is given as follows:

m < 1 = 150º.

The equation of a vertical asymptote to the graph of y = sec(6x - π) is x = π/6. Hence, option a is correct.

The function y = sec(6x - π) has vertical asymptotes at the values of x where the denominator of sec(6x - π) becomes zero. The reciprocal of sec(θ) is cos(θ). Because the cosine function has the values π/2, 3π/2, 5π/2, we will insert such an input that we get 0 in denominator.

6x - π = π/2

Solving for x,

6x = π/2 + π

6x = 3π/2

x = (3π/2) / 6

Applying the rules for the constant, logarithm and exponents, the derivative of the given function is of:

f'(x) = 3/x - 6x² - 8/(x^5).

The function is given by:

f(x) = √2^3 + ln(x^3) - 2x^3 - log_3(729) - 2/x^4

The derivative of a sum is the sum of the derivatives, hence:

f'(x) = (√2^3)' + (ln(x^3))' - (2x^3)' - (log_3(729))' - (2/x^4)'

The derivative of a constant is of zero, hence:

Hence:

f'(x) = (ln(x^3))' - (2x^3)' - (2/x^4)'.

The derivative of the logarithm is given by:

ln(h(x))' = (1/h(x)) x h'(x).

Hence:

(ln(x^3))' = 3x²/x³ = 3/x.

The derivative of the power of x is given by:

The inequality that represents the total insurance expenses is x< 23,750.

A company's insurance costs include the cost of the insurance contract as well as any additional premium payments. The company's payment is recorded as an expense for the given accounting period.

The out-of-pocket maximum of $5,000 is the maximum amount the client will pay, which includes the deductible ($250) and the coinsurance (20% of the insured expenses). Therefore, the total insured expenses (x) must be less than the out-of-pocket maximum plus the deductible:

x < $5,000 + $250 = $5,250

Since the client has a 20% co-insurance, the client will pay 20% of the insured expenses and the insurance company will pay the rest. Therefore, the total amount the client will pay for the insured expenses is:

$250 + 0.20x

Since this amount must be less than the out-of-pocket maximum of $5,000:

$250 + 0.20x < $5,000

Step-by-step explanation:

The value of r that indicates a stronger correlation is option (C) r = -0.912 represents a stronger correlation because |-0.912|>|0.721|

The value of the correlation coefficient, denoted by "r", ranges from -1 to 1. A correlation of -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation. The absolute value of the correlation coefficient (|r|) represents the strength of the correlation, where the closer |r| is to 1, the stronger the correlation is.

In this case, r = 0.721 indicates a moderate positive correlation, while r = -0.912 indicates a strong negative correlation. The absolute value of -0.912 is greater than the absolute value of 0.721, indicating that the strength of the negative correlation is stronger than the strength of the positive correlation.

Therefore, the correct option is (C) r = -0.912 represents a stronger correlation because |-0.912|>|0.721|

The curve is y = In(sec(x)) and we have to find its length. We are given the range as 0 ≤ x ≤ π/4. So, the formula for the length of the curve is given as:

To solve for the length of the curve of y = In(sec(x)), we use the formula,

`L = ∫[a,b] √[1+(f′(x))^2] dx`.Where, `a = 0` and `b = π/4`. And `f′(x)` is the derivative of `In(sec(x))`.

We know that:`f′(x) = d/dx[In(sec(x))]`

Using the formula of logarithm differentiation, we can write the above equation as:

`f′(x) = d/dx[In(1/cos(x))]`

So,`f′(x) = -d/dx[In(cos(x))]`

Therefore,`f′(x) = -sin(x)/cos(x)`

Substituting the values, we get:

`L = ∫[a,b] √[1+(f′(x))^2] dx`

`L = ∫[0,π/4] √[1+(-sin(x)/cos(x))^2] dx`

`L = ∫[0,π/4] √[(cos^2(x)+sin^2(x))/(cos^2(x))] dx`

`L = ∫[0,π/4] sec(x) dx`

Now, `L = ln(sec(x) + tan(x)) + C` where `C` is a constant.

We calculate the constant by substituting the values of `a = 0` and `b = π/4`:

`L = ln(sec(π/4) + tan(π/4)) - ln(sec(0) + tan(0))`

`L = ln(√2 + 1) - ln(1 + 0)`

`L = ln(√2 + 1)`

Thus, the exact length of the curve is `ln(√2 + 1)` units.

Thus, the exact length of the curve of y = In(sec(x)), 0≤x≤π/4 is `ln(√2 + 1)` units.
