Draw an irregular 14-sided polyhedron which has two congruent bases.
An irregular 14-sided polyhedron which has two congruent bases is as shown in the attached file.
What is a Polyhedron?
A polyhedron is a three dimensional solid shape made by joining together polygons.
For example we can consider a prism having 12-sided regular polygons as bases because then there would be 2 bases and 12 lateral sides for a total of 14 sides for the polyhedron.
Since the lateral faces are rectangles and not 12-sided polygons like the bases, the polyhedron is an irregular polyhedron.
Applying the above, we can draw an irregular 14-sided polyhedron which has two congruent bases as shown in the attached file.

Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
and the sum of all angles around a single point on one side of a line is also always 180° (because that line is like a diameter of any circle with that point as center, and half a circle is 180°).
3)
the third inner angle of the triangle is
180 = 63 + 51 + angle = 114 + angle
angle = 66°.
x = 180 - 66 = 114°
4)
the third inner angle of the triangle is
180 = 86 + 45 + angle = 131 + angle
angle = 49°
x + 30 = 180 - 49 = 131°
x = 101
a rectangular plot of land measures 40.0 m by 120.0 m, with a parcel 10.0 m by 12.0 m out of one corner for an electrical transformer. what is the area, in meters squared, of the remaining plot?
The area of the remaining rectangular plot of land is 4680m²
Area of rectangle:
Area of rectangle means the area covered by the rectangle.
The formula for area of rectangle is
A = l x b
where,
l is the length of the rectangle
b is the breadth or width of the rectangle
Given,
A rectangular plot of land measures 40.0 m by 120.0 m, with a parcel 10.0 m by 12.0 m out of one corner for an electrical transformer.
Here we need to find the remaining area of the rectangular plot land.
For that first, we have to find the area of each separately,
Like,
The area of the rectangular plot is,
A₁ = 40.0 x 120.0 m²
A₁ = 4800m²
Similarly, the area of the electric transformer is,
A₂ = 10.0 x 12.0 m²
A₂ = 120m²
Now the remining area is,
A = A₁ - A₂
A = 4800 - 120 m²
A = 4680m²
Therefore, the area of the remaining rectangular plot is 4680m².

Distributionally robust stochastic optimization (DRSO) is a framework for decision-making problems under certainty, which finds solutions that perform well for a chosen set of probability distributions.
Review on r. gao and a. j. kleywegt. distributionally robust stochastic optimization with wasserstein distance -
A paradigm for decision-making under certainty called distributionally resistant stochastic optimization (DRSO) seeks solutions that function well for a specified set of probability distributions. There have been many different methods offered for describing a set of distributions. The decision is significant since it has an impact on the outcomes, and the relative effectiveness of various options depends on the traits of the issues. In this study, we take into account issues where various random variables show some degree of reliance, but the precise values of the parameters describing the dependence are unknown.We also get the DRSO problem in a dual reformulation. The formulation also has the advantage of avoiding a problem related to the one-sided moment constraints in moment-based DRSO issues, which is a desirable result.Learn more about DRSO

Your friend has $100 when he goes to the fair. he spends $10 to enter the fair and $20 on food. rides at the fair cost $2 per ride. which function can be used to determine how much money he has left over after x rides? f(x) = −2x 70 f(x) = 2x 70 f(x) = −2x − 70 f(x) = −30x $100
The function which can be used to determine the amount of money he has left over after x rides is f(x)=-2x+70.
This function is linear. A linear variable function can be written in the form of y=f(x)=a+bx, where a and b are integers and x, is the variable. This function has one independent variable and one dependent variable. In the above given function y=f(x)=a+bx; y is the dependent variable and x is the independent variable.
Here since x number of rides are taken and the cost per ride is x so the total cost of x rides is given as 2x.
Since there is a total of $100 and an amount of ($10+$20=$30) is spent on entry and food respectively.
Therefore, total amount left after all the expenses can be expressed as:
f(x)=100-(30+2x)
f(x)=70-2x
f(x)=-2x+70
Therefore, function which can be used to determine the amount of money he has left over after x rides is f(x)=-2x+70.

How can you use surveys, experiments and observational studies to make inferences about a population?
Surveys, Experiments, and Observational studies are some common methods of data collection in statistical studies that involve people.
A survey is a means to gather information about a group of individuals by asking some of them to respond to questions. A survey may require participants to fill out forms, respond to online questionnaires, take part in in-person interviews, or respond to questions over the phone.
In an experiment, as opposed to an observational study, different treatments are purposefully applied to several groups, and the groups are then compared to see whether there are any differences in a certain variable of interest termed a response. Researchers can determine whether various treatments have distinct effects by using a well-designed experiment.
In an observational study, a researcher utilizes data from observations to learn about a group of people. Aside from assessing their replies, the people being watched are particularly not hampered.

Hiroshi and Giulio share a common investment goal and once they reach their goals, they will withdraw their money.

times as much money as Hiroshi and it takes Hiroshi 5
5
times longer than Giulio to reach this goal.
They both use the same bank that provides a 5
5
% annual interest rate compounded quarterly.
Work out how long it takes Hiroshi to reach his investment goal?
Give your answer correct to the nearest year.
It takes Hiroshi 30 years to reach his investment goal.
The formula for calculating the amount received on the principal amount (P) after t years at r% rate of interest is-
Amount = P(1 + r/100)^t
Let the principle amount with Hiroshi be P
then, the amount that Giulio starts with = 3P
Let time period for Giulio's investment = t
Then, the time period for Hiroshi's investment = 5t
Rate = 5%
As the investment goals of both the people are equal, they will get the same amount.
Therefore, we get the following equation-
P(1 + 20/100)^5t/4 = 3P(1 + 20/100)^t/4
(1 + 20/100)^5t/4 = 3(1 + 20/100)^t/4
[(1 + 20/100)^5t/4] /[(1 + 20/100)^t/4] = 3
(1 + 20/100)^(5t/4- t/4) = 3
(1 + 20/100)^(4t/4) = 3
(1 +0.2)^t = 3
(1.2)^t = 3
Taking log on both sides-
Log (1.2)^t = log 3
t log 1.2 = log 3
t = log 3/ log 1.2
t = 6.025
Time taken by Hiroshi to reach his investment goal = 5t
= 5(6.025)
= 30.128
Thus, it takes Hiroshi 30 years to reach his investment goal.

Convert 99 grams into pounds. Round your answer to the nearest hundredth.
Convert 99 grams into pounds is 0.22.
In the US, the pound is the unit of mass that is utilized. It is symbolized by the letter lbs. Therefore, we must calculate the estimated number of grams in a pound. Both pounds and grams can be converted into one another as units of mass.
Since both systems of units may carry the same mass, the fundamental conversion rate between pounds and grams is crucial for international trade. Because just writing the numbers makes no sense, units should always be written after the final solution has been evaluated. The method of transposition may be used to discover the conversion of a given number of values from one unit to another by multiplying or dividing both sides of the equation by the same number.
Covert the unit = 99 gram
