Answer:

[tex]728 \: {m}^{2} [/tex]

Step-by-step explanation:

Given:

l = 15 m (length)

w = 16 m (width)

h = 4 m (height)

Find: a (surface) - ?

First, let's find the area of the base:

a (base) = l × w

a (base) = 15 × 16 = 240 m^2

Since the rectangular prism has 2 bases, we multiply this number by 2:

240 × 2 = 480 m^2 (area of both bases)

Now, let's find the lateral surface area:

a (lateral) = 2(4 × 15) + 2(4×16) = 2 × 60 + 2 × 64 = 120 + 128 = 248 m^2

Finally, in order to find the whole surface area, we have to add the lateral surface area and both bases area together:

a (surface) = a (lateral) + a (base)

a (surface) = 248 + 480 = 728 m^2

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 answer to the given question about IQR is option b Bus 14, with an IQR of 6.

To determine which bus is the most consistent, we need to look at the measure of variability for each data set. In this case, we are given the interquartile range (IQR) and the range for each bus. The IQR is a better measure of variability than the range because it is less affected by outliers.

Bus 47 has an IQR of 8, which means that the middle 50% of the data falls within a range of 8 minutes. Bus 14 has an IQR of 6, which means that the middle 50% of the data falls within a range of 6 minutes.

Since Bus 14 has a smaller IQR, it is more consistent than Bus 47. This means that the travel times for Bus 14 are more similar to each other than the travel times for Bus 47. Therefore, we can conclude that Bus 14 is the most consistent of the two buses.

Therefore, the correct answer is:

Bus 14, with an IQR of 6.

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.

Step-by-step explanation:

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.

a. The scale factor of the smaller cylinder to the larger cylinder is the ratio of their radii, which is 4/6 or 2/3.

b. The circumference of the base of a cylinder is given by 2πr, where r is the radius of the base. Thus, the ratio of the circumferences of the bases of the two cylinders is:

(2π)(4)/(2π)(6) = 4/6 = 2/3

c. The lateral area of a cylinder is given by the formula 2πrh, where r is the radius of the base and h is the height. The ratio of the lateral areas of the two cylinders is:

(2π)(4)(9)/(2π)(6)(9) = 4/6 = 2/3

d. The volume of a cylinder is given by the formula πr²h. Thus, the ratio of the volumes of the two cylinders is:

(π)(4²)(9)/ (π)(6²)(9) = 16/36 = 4/9

e. If the volume of the smaller cylinder is 144π cm³, then we can use the formula for the volume of a cylinder to solve for the height of the smaller cylinder:

144π = π(4²)h

h = 9 cm

Since the two cylinders are similar, we know that the ratio of their heights is the same as the ratio of their radii, which is 2/3. Thus, the height of the larger cylinder is:

(2/3)(9) = 6 cm

Using the formula for the volume of a cylinder, we can now calculate the volume of the larger cylinder:

V = π(6²)(6) = 216π cm³

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.

To find the weight of the puppy when it is 15 weeks old, we need to substitute 15 for x in the equation of the line of best fit:

y = 2x + 1.5

y = 2(15) + 1.5

y = 31.5

Therefore, the weight of the puppy when it is 15 weeks old is 31.5 units, where the units depend on the units used to measure weight (e.g. pounds, kilograms, etc.).

Therefore , the solution of the given problem of volume comes out to be  roughly 1,814.4 cubic feet.

A three-dimensional object's volume, which is expressed in cubic units, indicates how much space it takes up. These symbols for cubic dimensions are liter and in3. However, you must be aware of an object's volume in order to calculate its dimensions. It is standard practice to translate an object's weight to mass units like grams and kilograms.

Here,

V = r2h, where r is the radius and h is the height, is the expression for a cylinder's volume.

We are informed that the cylindrical has a 9-foot height and an 8-foot radius. (since the diameter is 16 ft).

When the formula's numbers are substituted, we obtain:

=> V = π(8 ft)²(9 ft)

=> V = π(64 ft²)(9 ft)

=> V = 1,814.37 ft³

We can calculate this result as V = 1,814.4 ft³ by rounding to the nearest tenth.

The cylinder's capacity is therefore roughly 1,814.4 cubic feet.

Therefore, according to Paul's model, a student who spends 3 hours on homework is predicted to get a test score of 64.

In mathematics, a function is a rule or relationship that maps each input value (also known as the "argument" or "independent variable") to a corresponding output value (also known as the "value" or "dependent variable").

In other words, a function is a way to describe how one set of values (the inputs) are transformed into another set of values (the outputs). Functions are often represented using algebraic equations or graphical representations, such as graphs or charts.

For example, the function f(x) = 2x + 1 maps each input value x to the output value 2x + 1. So, if we input x=2, the output value would be f(2) = 2(2) + 1 = 5. Similarly, if we input x=3, the output value would be f (3) = 2(3) + 1 = 7.

(a) Based on the scatter plot, we can see a positive linear relationship between the hours spent on homework and the test scores. As the number of hours spent on homework increases, the test scores also tend to increase.

(b) To use Paul's function to predict the test score for 3 hours of homework, we can substitute x = 3 into the equation:

[tex]y = 8x + 40[/tex]

[tex]y = 8(3) + 40[/tex]

[tex]y = 24 + 40[/tex]

[tex]y = 64[/tex]

Therefore, according to Paul's model, a student who spends 3 hours on homework is predicted to get a test score of 64.

(c) In the context of the situation, the number 40 in Paul's model represents the baseline or minimum test score that a student would get if they didn't study at all. This is the y-intercept of the line and indicates that a student who does not spend any time on homework is predicted to get a score of 40.

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).

The solutions to the equation log4(x² - 2x) = log4(3x + 8) are x = 8 and x = -1.

To solve the equation log4(x² - 2x) = log4(3x + 8), we can use the property of logarithms that says if logb(a) = logb(c), then a = c.

Using this property, we can set the expressions inside the logarithms equal to each other:

x² - 2x = 3x + 8

Now we have a quadratic equation that we can solve:

x² - 2x - 3x - 8 = 0 x² - 5x - 8 = 0

We can factor this equation using the product-sum method:

x² - 5x - 8 = (x - 8)(x + 1)

Setting each factor equal to zero gives us the possible solutions:

x - 8 = 0 or x + 1 = 0

Solving for x in each case gives us:

x = 8 or x = -1

However, we need to check if either of these solutions make the argument of the logarithm negative or zero. If the argument is negative or zero, then the logarithm is undefined.

For the first solution, x = 8, we have:

log4(8² - 2(8)) = log4(3(8) + 8) log4(48) = log4(32)

Both arguments are positive, so x = 8 is a valid solution.

For the second solution, x = -1, we have:

log4((-1)² - 2(-1)) = log4(3(-1) + 8) log4(3) = log4(5)

Again, both arguments are positive, so x = -1 is also a valid solution.

Therefore, the solutions to the equation log4(x² - 2x) = log4(3x + 8) are x = 8 and x = -1.
