The amount of money in an account at the end of 5 years will be $14,014.40.

To calculate this, we can use the continuous compounding formula: [tex]A = Pe^(rt)[/tex] where P = 10,000, r = 6.75% (0.0675), t = 5.

Now, the amount of money in an account at the end of 5 years will be:

A = 10,000*e^(0.0675*5)

A = 10,000*e^0.3375

A = 10,000*1.40143960839

A = 14014.3960839

A = $14,014.40

The probability that an individual has a total cholesterol level between 200 and 250 is calculated to be approximately 0.5020 or 50.2%.

To solve this problem, we need to find the z-scores corresponding to the lower and upper bounds of the cholesterol range, and then find the area under the normal distribution curve between these z-scores.

First, we calculate the z-score for 200:

z1 = (200 - 219) / 41.6 = -0.455

Next, we calculate the z-score for 250:

z2 = (250 - 219) / 41.6 = 0.746

Now we can use a standard normal distribution table or calculator to find the area between these two z-scores:

P(-0.455 < Z < 0.746) ≈ 0.5020

This means that the probability that an individual has a total cholesterol level between 200 and 250 is approximately 0.5020 or 50.2% (rounded to one decimal place).

The actual population mean is between 1.5 and 2.1 vehicles per household.

The median is a statistical measure that represents the middle value of a dataset. It is the value that separates the lower half of the dataset from the upper half. To find the median, the data must be arranged in order from smallest to largest, and then the middle value is identified.

If the dataset contains an odd number of values, then the median is the middle value. For example, if the dataset is {2, 4, 6, 7, 9}, then the median is 6, which is the middle value.

If the dataset contains an even number of values, then the median is the average of the two middle values. For example, if the dataset is {2, 4, 6, 7, 9, 10}, then the median is (6+7)/2 = 6.5, which is the average of the two middle values, 6 and 7.

The actual population mean is between 1.5 and 2.1 vehicles per household.

The margin of error represents the possible distance between the sample mean and the true population mean.

The lower bound is found by subtracting the margin of error from the sample mean:

1.8 - 0.3 = 1.5

The upper bound is found by adding the margin of error to the sample mean:

1.8 + 0.3 = 2.1

Therefore, we can be 95% confident that the true population mean falls between 1.5 and 2.1 vehicles per household.

Port C is approximately 148.96 kilometers to the east of Port A, at a bearing of 013.93 degrees from the positive x-axis.

How to find distance and direction?

To find the distance and direction of Port C from Port A, we can use basic trigonometry and vector analysis.

First, we need to draw a diagram of the situation. We can assume that Port A is located at the origin (0,0) of a two-dimensional coordinate system, and that the ship sails in a straight line from A to B on a bearing of 050 degrees, which means that its direction is 40 degrees clockwise from the positive x-axis. Since Port B is 80 kilometers to the east of A, we can represent it as the point (80,0) in the coordinate system.

Next, the ship sails from B to C on a bearing of 062 degrees, which is 22 degrees clockwise from its previous direction. To calculate the distance and direction of C from A, we need to find the vector that represents the displacement of the ship from B to C, and add it to the vector that represents the displacement from A to B.

To find the vector that represents the displacement from B to C, we can use basic trigonometry. Let d be the distance from B to C, and let θ be the angle between the displacement vector and the positive x-axis. Then, we have:

cos(θ) = adjacent/hypotenuse = 80/d

sin(θ) = opposite/hypotenuse = (d*sin(22))/d = sin(22)

Solving for d, we get:

d = 80/cos(θ) = 80/cos(arctan(sin(22)/cos(22))) ≈ 92.56 km

Therefore, the vector that represents the displacement from B to C is (dcos(θ), dsin(θ)) ≈ (64.39 km, 35.77 km) in the coordinate system.

To find the vector that represents the displacement from A to C, we can add the two vectors:

(80,0) + (64.39,35.77) ≈ (144.39,35.77)

Therefore, the distance from A to C is the magnitude of this vector:

|AC| = sqrt((144.39)² + (35.77)²) ≈ 148.96 km

To find the direction of C from A, we can use the inverse tangent function:

tan⁻¹(35.77/144.39) ≈ 13.93 degrees

Therefore, Port C is approximately 148.96 kilometers to the east of Port A, at a bearing of 013.93 degrees from the positive x-axis.

The probability that the average size of the fish you caught is more than 13 inches is approximately 0.0918, or about 9.18%.

We can use the Central Limit Theorem to approximate the distribution of the sample mean. According to the theorem, the sample mean of a sufficiently large sample will be approximately normally distributed with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size.

In this case, we have a sample size of 4, which may not be considered sufficiently large, but we can still use the approximation. Thus, the distribution of the sample mean can be approximated as:

mean = 11

standard deviation = 3 / sqrt(4) = 1.5

To find the probability that the average size of the fish you caught is more than 13 inches, we need to standardize the sample mean using the z-score formula:

z = (x - mean) / standard deviation

where x is the sample mean we want to find the probability for. Plugging in the values, we get:

z = (13 - 11) / 1.5 = 1.33

Now, we need to find the probability of getting a z-score greater than 1.33 in a standard normal distribution table or calculator. Using a calculator or statistical software, we find that this probability is approximately 0.0918.

Therefore, the probability that the average size of the fish you caught is more than 13 inches is approximately 0.0918, or about 9.18%.

With the help of given expression 2n + 1 = 157,  the first number is 78.

What exactly are expressions?

In mathematics, an expression is a combination of numbers, symbols, and operators that represent a value. It can be a single term, or it can be a combination of terms connected by operators. For example, 2x + 5 is an expression with two terms connected by the operator +. Expressions can also include functions, variables, and constants.

Now,

Let's assume the first number be x=n. Then the next consecutive number will be x+1.

According to the given information, the sum of the two consecutive numbers is 157.

So, we can write the equation as:

x + (x+1) = 157

Simplifying the equation, we get:

2x + 1 = 157

Subtracting 1 from both sides, we get:

2x = 156

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = (- 3, - 1 ) , then

y = a(x - (- 3) )² + (- 1)

y = a(x + 3)² - 1

to find a substitute the coordinates of any other point on the graph into the equation.

using (- 2, 0 )

0 = a(- 2 + 3)² - 1

0 = a(1)² - 1

0 = a - 1 ( ad 1 to both sides )

To find:-

Answer:-

The given coordinates of the triangle are , A(3,-4) ; B(-2,1) and C(5,0) .

To find out the coordinate of the centroid we can use the below formula ,

[tex]\longrightarrow \boxed{\rm{Centroid\ (G)}= \bigg(\dfrac{x_1+x_2+x_3}{3},\dfrac{y_1+y_2+y_3}{3}\bigg)} \\[/tex]

where ,

On substituting the respective values, we have;

[tex]\longrightarrow G =\bigg(\dfrac{3-2+5}{3},\dfrac{-4+1+0}{3}\bigg) \\[/tex]

[tex]\longrightarrow G =\bigg(\dfrac{ 6}{3},\dfrac{-3}{3}\bigg) \\[/tex]

[tex]\longrightarrow \boldsymbol{ G = (2,-1) }\\[/tex]

Hence the centroid of the given triangle is (2,-1) .

Now the given equation of the line is,

[tex]\longrightarrow x - 3y = 4 \\[/tex]

Convert this into slope intercept form of the line, which is,

Slope intercept form:-

[tex]\longrightarrow y = mx + c\\[/tex]

where, m is the slope of the line and c is the y-intercept .

So , we have;

[tex]\longrightarrow -3y = 4-x\\[/tex]

[tex]\longrightarrow 3y = x - 4 \\[/tex]

[tex]\longrightarrow y =\dfrac{x-4}{3} \\[/tex]

[tex]\longrightarrow y =\dfrac{1}{3}x-\dfrac{4}{3} \\[/tex]

On comparing it with the slope intercept form, we have;

[tex]\longrightarrow m =\dfrac{1}{3}\\[/tex]

Secondly we know that the slopes of parallel lines are equal . So the slope of the line parallel to the given line would also be ⅓ .

Now we may use point slope form of the line to find out the equation of the required line. The point slope form of the line is,

Point slope form:-

[tex]\longrightarrow y - y_1 = m(x-x_1) \\[/tex]

where the symbols have their usual meaning.

Here the line will pass through the centroid of the triangle which is (2,-1) .

On substituting the respective values, we have;

[tex]\longrightarrow y - (-1) =\dfrac{1}{3}(x-2) \\[/tex]

[tex]\longrightarrow 3( y +1) = x - 2 \\[/tex]

[tex]\longrightarrow 3y + 3 = x -2\\[/tex]

[tex]\longrightarrow x - 2 - 3 - 3y = 0 \\[/tex]

[tex]\longrightarrow\boxed{\boldsymbol{ x - 3y - 5 =0}} \\[/tex]

The correct centre measure, with a mean value of approximately 5 gallons, will be C. Coffee Ground, with a mean value of about 5 gallons, which will show which shop usually sells the most coffee per hour.

By summing up all the data points and dividing by the total number of data points, the mean is determined.

To determine which coffee shop typically sells the most amount of coffee per hour, we can compare the measures of center, specifically the mean and median, of the two datasets.

Calculating the mean for each dataset, we get:

Coffee Ground: (1.5+20+3.5+12+2+5+11+7+2.5+9.5+3+5)/12 = 6.125 gallons

Wide Awake: (2.5+10+4+18+4+3+6+5+2.5)/9 = 6.0556 gallons

Therefore, Coffee Ground has a higher mean than Wide Awake, suggesting that Coffee Ground typically sells more coffee per hour.

Calculating the median for each dataset, we get:

Coffee Ground: 5 gallons

Wide Awake: 4.5 gallons

Therefore, the median for Wide Awake is lower than that of Coffee Ground, suggesting that Wide Awake typically sells less coffee per hour.

Based on these measures of center, we can conclude that the answer is: C. Coffee Ground, with a mean value of about 5 gallons.

The probability that a randomly selected user is online less than 15 hours a week is 0.1056 (approx).

As per the given statement, u.s. internet users spend an average of 18.3 hours a week online. If 95% of users spend between 13.1 and 23.5 hours a week, we need to determine the probability that a randomly selected user is online less than 15 hours a week.

To find the probability that a randomly selected user is online less than 15 hours a week, we need to use the Z-score formula, which is defined as:

Z = (X - μ) / σ

Where Z is the z-score, X is the value of the element, μ is the mean of the population, and σ is the standard deviation. Therefore, the probability of a randomly selected user being online less than 15 hours per week can be calculated as follows:Z = (15 - 18.3) / σ

We know that 95% of users spend between 13.1 and 23.5 hours per week, which means that the standard deviation is given by:

13.1 - 18.3 = 5.4 hours (lower bound)

23.5 - 18.3 = 5.2 hours (upper bound)

Therefore, σ = (5.4 + 5.2) / 4 = 2.65 hours

Hence, the z-score can be calculated as follows:Z = (15 - 18.3) / 2.65 = -1.25

Thus, the probability that a randomly selected user is online less than 15 hours a week is P(Z < -1.25). Using a standard normal distribution table, we can find that P(Z < -1.25) = 0.1056 (approx).
