The total volume of all 4 gumballs: V=3,620 mm³

Gumball is in the shape of a Spherical so we Use the formula for the total volume of a sphere:

Volume of Sphere = (4/3)πr³

r = Radius of Sphere

Plug the given radius into the formula, r =  6mm

Volume of 1 gumball = (4/3)π * 6³

V= 288π  mm³

The total volume of a single gumball will be 288π cubic millimeters.

Because you have 4 gumballs, multiply the total volume of a gumball by 4 to find the total volume for all 4 gumballs.

Volume of 4 gumballs = 4 *  288π

V= 1152π  mm³

In terms of π, the total volume of the 4 gumballs is 1152π cubic millimeters.

Assuming π = 3.14, multiply 1152 and 3.14 together.

1152*3.14= 3,617.28 mm³

The problem is asking us to calculate the probability that less than 200 of 500 cell phone calls selected at random will be spam, given that First Orion estimates 45% of all cell phone calls in 2019 will be spam. To solve this problem, we can use the normal approximation to the binomial distribution.

First, we need to find the mean and standard deviation of the binomial distribution. The mean is given by:

μ = n * p

where n is the number of trials (500) and p is the probability of success (i.e., a cell phone call is spam) on a single trial (0.45):

μ = 500 * 0.45 = 225

The standard deviation is given by:

σ = sqrt(n * p * (1 - p))

σ = sqrt(500 * 0.45 * (1 - 0.45)) = 11.79

Next, we can use the normal approximation to calculate the probability that less than 200 of the 500 cell phone calls selected at random will be spam. We need to standardize the value of 200 using the mean and standard deviation of the binomial distribution:

z = (x - μ) / σ

where x is the number of successes (i.e., spam calls) we're interested in (200):

z = (200 - 225) / 11.79 = -2.12

We can use a standard normal distribution table or calculator to find the probability that a standard normal random variable is less than -2.12. This probability is approximately 0.017.

Therefore, the probability that less than 200 of the 500 cell phone calls selected at random will be spam is approximately 0.017 or 1.7%.

This type of data is cross-sectional data.

In statistics and econometrics, cross-sectional data, or a cross-section of a study population, is a type of data gathered by monitoring numerous subjects (such as individuals, firms, countries, or regions) at one point or throughout the course of time. It's also possible that the analysis disregards variations in time. Cross-sectional data analysis often entails contrasting the variations among pre-selected respondents.

Time series data, in which the same small-scale or aggregate entity is seen multiple times in time, differs from cross-sectional data. A different kind of data called panel data (also known as longitudinal data) combines the concepts of cross-sectional and time series data and examines how the topics (firms, people, etc.) develop throughout a time series. Panel data differs from cross-sectional data that has been pooled over time.

To find the dimensions that will create the maximum area of the prop section, we need to analyze the given equation A = -x^2 + 40. The equation represents a quadratic function in the form of A = -x^2 + 40., where A represents the area of the prop section and x represents the dimension.

The quadratic function is in the form of a downward-opening parabola since the coefficient of is negative (-1 in this case). The vertex of the parabola represents the maximum point on the graph, which corresponds to the maximum area of the prop section.

To determine the x-coordinate of the vertex, we can use the formula x = -b / (2a), where the quadratic equation is in the form Ax^2 + Bx + C and a, b, and c are the coefficients. In this case, the equation is -x^2 + 40, so a = -1 and b = 0. Plugging these values into the formula, we get x = 0 / (-2 * -1) = 0.

Therefore, the x-coordinate of the vertex is 0. To find the corresponding y-coordinate (the maximum area), we can substitute x = 0 into the equation  A(x) = -x^2 + 40: A(0) = -(0)^2 + 40 = 40.

Hence, the equation that reveals the dimensions that will create the maximum area of the prop section is A = 40. This means that regardless of the dimension x, the area of the prop section will be maximized at 40 units.

The angle ∠MPR is an obtuse angle, ∠RPN is a right angle and ∠NPS is an acute angle.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.

Given the angles ∠of MPR, ∠RPN, and ∠NPS.

Now,

The right angle is the angle with 90° (perpendicular rays) so  ∠RPN will be the right angle.

An angle less than 90° will be an acute angle so ∠NPS will be acute angle.

An angle greater than 90° will be an obtuse angle so ∠MPR will be an obtuse angle.

Hence "The angle ∠MPR is an obtuse angle, ∠RPN is a right angle and ∠NPS is an acute angle".

The solution for the system is (0,3) as line a meets the y-axis at (0, -3) and the Intersection point of a and b is (3,0). This makes it obvious that the solution for x will be 0 when the solution for y is 3

Given that the number graph ranges from negative eight to eight on the x-axis and negative eight to eight on the y-axis.

Two lines that are perpendicular to each other intersect at (three, zero). The line with a positive slope is labeled a, and the line with a negative slope is labeled b.

The system is given byx – y = 3 (line a)x + y = 3 (line b)We know that both the lines a and b pass through (3,0).

Let's first find the points of intersection of the line a with the x-axis and the y-axis.

To find the point of intersection of the line a with the x-axis, put y = 0 in the equation x - y = 3x - 0 = 3x = 3So, the point of intersection of line a with the x-axis is (3,0).

To find the point of intersection of the line a with the y-axis, put x = 0 in the equation x - y = 3 0 - y = 3y = -3So, the point of intersection of line a with the y-axis is (0,-3).

Similarly, let's find the points of intersection of the line b with the x-axis and the y-axis.

To find the point of intersection of the line b with the x-axis, put y = 0 in the equation x + y = 3x + 0 = 3x = -3So, the point of intersection of line b with the x-axis is (-3,0).

To find the point of intersection of the line b with the y-axis, put x = 0 in the equation x + y = 3 0 + y = 3y = 3So, the point of intersection of line b with the y-axis is (0,3).

Now, we can plot the graph of the two lines a and b and then find the points of intersection as follows:

Therefore, the solution for the system is (0,3) as line a meets the y-axis at (0, -3) and the intersection point of a and b is (3,0). This makes it obvious that the solution for x will be 0 when the solution for y is 3.

It will take Jamie 31 months to recoup her investment in the solar panels.

To calculate the time it takes to recoup the investment, we can use the formula for the number of periods needed to reach a future value with compound interest. In this case, the future value is the cost of the solar panels ($33,588.0), and the interest rate is 12% per year, compounded monthly.

We need to find the number of months it takes to reach a future value of $33,588.0 with monthly contributions of $1,200 and a monthly interest rate of 1% (12% divided by 12).

Using the formula for the number of periods (n) needed to reach a future value (FV) with monthly contributions (PMT) and monthly interest rate (r), we have:

FV = PMT * [(1 + r)ⁿ - 1] / r

$33,588.0 = $1,200 * [(1 + 0.01)ⁿ - 1] / 0.01

Solving for n, we find n ≈ 31 months. Therefore, it will take Jamie 31 months to recoup her investment in the solar panels.

Answer:

It is 36

Step-by-step explanation:

Answer:

\((a)\ Area = 195\pi\)

\((b)\ Volume = 700\pi\)

Step-by-step explanation:

Given

\(h = 12\)

\(d_1 = 10\) --- lower diameter

\(d_2 = 20\) --- upper diameter

Solving (a): The curved surface area

This is calculated as:

\(Area = \pi l(r_1 + r_2)\)

Where

\(r_1 = 0.5 * d_1 = 0.5 * 10 = 5\) --- lower radius

\(r_2 = 0.5 * d_2 = 0.5 * 20 = 10\) --- upper radius

And

\(l = \sqrt{h^2 + (r_1 - r_2)^2\) ---- l represents the slant height of the frustrum

\(l = \sqrt{12^2 + (5 - 10)^2\)

\(l = \sqrt{12^2 + (-5)^2\)

\(l = \sqrt{144 + 25\)

\(l = \sqrt{169\)

\(l = 13\)

So, we have:

\(Area = \pi l(r_1 + r_2)\)

\(Area = \pi * 13(5 + 10)\)

\(Area = \pi * 13(15)\)

\(Area = 195\pi\)

Solving (b): The volume

This is calculated as:

\(Volume = \frac{1}{3}\pi * h * (r_1^2 + r_2^2 + (r_1 * r_2))\)

This gives:

\(Volume = \frac{1}{3}\pi * 12 * (5^2 + 10^2 + (5 * 10))\)

\(Volume = \frac{1}{3}\pi * 12 * (25 + 100 + (50))\)

\(Volume = \frac{1}{3}\pi * 12 * (175)\)

\(Volume = \pi *4 * 175\)

\(Volume = 700\pi\)

h = height of the prism

Step-by-step explanation:

The correlation between X and Y, captured by the joint pmf Px,y(x,y), allows for this difference in heights and explains the seemingly contradictory result.

The given scenario states that there is a joint probability mass function (pmf) Px,y(x,y) with marginal probabilities Px(u) = Py(u) for all u. However, it also states that the probability of Y being greater than X, P(Y > X), is greater than or equal to 0.9.

This situation seems contradictory at first, as the marginals are equal but the probability of Y being greater than X is significantly high. However, it is important to note that the joint pmf Px,y(x,y) accounts for the correlation between X and Y, not just their marginals.

The correlation between X and Y allows for the possibility that Y may be greater than X with a high probability, even though the marginals are equal. This indicates a dependence between the two random variables.

To illustrate this, let's consider an example where X and Y represent the heights of two groups of individuals. The equal marginals Px(u) = Py(u) imply that the heights in each group have the same distribution. However, the high probability of Y being greater than X (P(Y > X) ≥ 0.9) suggests that, on average, the individuals in one group tend to be taller than those in the other group.

Therefore, the correlation between X and Y, captured by the joint pmf Px,y(x,y), allows for this difference in heights and explains the seemingly contradictory result.
