The volume of a frustum of a pyramid with given dimensions is 6260 cubic units.
What is frustum of pyramid?
The top of a conventional pyramid is removed to create the frustum, which is a pyramid. It is known as a truncated pyramid for this reason. The height of a pyramid is represented by the letter h and is the distance from its base to its summit. Similar to it, it has two bases and a slant height indicated by the letter "s" (top and bottom).
We are given frustum of a pyramid with square base of side 22, square top of side 13 and height 20.
We know that volume of frustum of pyramid(V) = h(b^2 + a^2 + ab)/3
We are given b = 22, a = 13 and h = 20
From this, we get
⇒V = h(b^2 + a^2 + ab)/3
⇒V = 20(22^2 + 13^2 + 22*13)/3
⇒V = 20(484 + 169 + 286)/3
⇒V = 20(939)/3
⇒V = 20*313
⇒V = 6260 cubic units
Hence, the volume of a frustum of a pyramid with given dimensions is 6260 cubic units.

What is a function?
A function is described as a relationship between a group of inputs with one output each. A function is, to put it simply, a relationship between inputs in which each input is connected to exactly one output. Every function has a domain and a codomain, or range. A function is typically represented by the notation f(x), where x represents the input. A function is typically shown as y = f(x).
The equation ax + by + c = 0 [1] represents the line in question. A list of pairs of coordinates for each intersection point and the number of intersections (count) should be returned by the function (list).
A list of items can be sent to the function count list, which will return the total number of objects in the list. The function returns the number of objects in the specified list after accepting an array or list of objects.
Hence, the equation that determines the intersection of line with a clipping triangle is ax + by + c = 0 [1].

Use the graph to determine if Malia can buy 75 water bottles
and 100 pairs of socks. Explain.
Malia can't buy 75 water bottles and 100 pairs of socks because it is not a solution to the system.
System of Inequalities:
The term "system of inequalities" refers to a collection of two or more disparities in one or more variables. When a problem demands a variety of solutions and those solutions must satisfy many constraints, systems of inequalities are used.
Now in the given question,
Here we have a graph of inequalities, and we just need to see if the pair (75, 100) is a solution.
The solutions of the system are all the points in the intersection of the two shaded areas (in this case are all the points in the green area)
Now, clearly the point (75, 100) is not a solution
Even if you evaluate that in the first inequality:
x + y ≥ 200
we get:
75 + 100 ≥ 200
175 ≥ 200
which is false.
So no, Malia can't buy 75 water bottles and 100 pairs of socks.

Let X be a random variable whose distribution is Normal, with a mean of 100 and a standard deviation of 10. The proportion of observations above 115 is equal to the proportion below what value? Use the fact that the normal distribution is symmetric about the mean.
The value for which the proportion of observations below it is equal to the proportion of observations above 115 is 85.
The normal distribution, also known as the Gaussian distribution or the bell curve, is a continuous probability distribution that describes the distribution of many real-world phenomena such as height, weight, IQ scores, and financial returns. It is a symmetric distribution with a bell-shaped curve that is centered on the mean and characterized by its mean and standard deviation.
Since the normal distribution is symmetric about the mean, the proportion of observations above 115 is equal to the proportion of observations below 100 - (115 - 100) = 85.
So, the value for which the proportion of observations below it is equal to the proportion of observations above 115 is 85.

The angles in a straight line are X degree, 3x degree and 6x degree. find the measure of each angle.
Answer:
"18", "54", and "108"
Step-by-step explanation:
Angles:A straight line has an angle of 180 degrees. It can be seen as "half a circle", which has an angle of... 360 degrees, and since it's half, it's just 180 degrees.
Now we're also given the angles that compose the straight line (x, 3x, and 6x), and by adding these angles together, we should get the angle of the straight line. So that means that: [tex]x+3x+6x=180[/tex]
Now from here we can just combine them all into one term:
[tex]10x=180[/tex]
Now divide both sides by 10:
[tex]x=18[/tex]
Our angles are equal to "x", "3x", "6x", and to calculate their value, we just plug in "18" as x giving us: "18", "3(18)", "6(18)" which simplifies to the angles: "18", "54", "108"

Ana opened a bank account with $1000 that earns interest, compounded continuously, at an annual rate of r. To calculate the amount of money in the account after t years, we can use the formula:
[tex]A = P * e^{(rt)}[/tex]
where A is the amount in the account after t years, P is the initial deposit (in this case, $1000), r is the annual interest rate, and e is the mathematical constant approximately equal to 2.718.
For example, if the interest rate is 5% (r = 0.05), after 1 year, the amount in the account would be:
[tex]A = \$1000 * e^{(0.05 * 1)} = \$1000 * 1.0517[/tex]

What does the result suggest about the accuracy of estimates of s found using the range rule of thumb? Assume the estimate is accurate if it is within 1.4 cm.
Therefore , the solution of the given problem of standard deviation comes out to be the range rule of thumb is only an approximation and does not take into account the shape of the distribution .
The standard deviation is defined.Variance is a measure of variation used in statistics. To calculate the average variance between the data and the mean, use the algorithm below. In opposition to other numerical measures of variability, it incorporates all data points into calculations by comparing each data point's value to the mean. Among the differences are unintentional errors, irrational expectations, and changing market or economic conditions.
Here,
According to the range rule of thumb, the range of the data set is roughly four times the standard deviation. Therefore, we can estimate the standard deviation by dividing the range by 4:
range = 196.9 - 154 = 42.9
estimated standard deviation = range / 4 = 10.725
Comparing this estimate to the actual standard deviation of 8.04 cm calculated using the 149 heights, we see that the estimate is off by about 2.685 cm.
This suggests that the estimate obtained using the range rule of thumb is not very accurate in this case, as it is outside the 1.4 cm threshold for accuracy.
This is not surprising, as the range rule of thumb is only an approximation and does not take into account the shape of the distribution or the sample size.

The slope of the least-squares regression line is not directly related to the fraction of the variation in the response variable that is explained by the explanatory variable.
The slope of the least-squares regression line is a numerical measure of the rate of change in the response variable for a unit change in the explanatory variable. It does not directly relate to the fraction of the variation in the response variable that is explained by the explanatory variable. This is because the fraction of the variation in the response variable that is explained is determined by the correlation coefficient, which is a measure of how well the regression line fits the data. The slope of the least-squares regression line is unitless, meaning it does not have any specific unit such as meters, seconds, or degrees. The slope of the least-squares regression line is simply a numerical measure of the rate of change in the response variable per unit change in the explanatory variable.

Step-by-step explanation:
the mean is an inappropriate measure of central tendency when the distribution is severely skewed because
The mean is sensitive to outliers and will not accurately represent the center of the data if the distribution is significantly skewed.
The mean is a measure of central tendency that is calculated by adding up all values in a dataset and dividing by the number of values. It is often used as a measure of average since it takes into account all values in the dataset. However, it is an inappropriate measure of central tendency when the data distribution is severely skewed. A skewed distribution is one in which the data is not distributed evenly around the mean, and the data is either concentrated in the lower or higher end of the range. Since the mean is sensitive to outliers, it will be greatly affected by these values and not accurately represent the center of the data. In this case, it is more appropriate to use the median as a measure of central tendency since it is not affected by outliers. The median is the middle value of a dataset when the data is sorted from smallest to largest and is a better representation of the true center of the data in a skewed distribution.
