TRUE: A molecule can adopt a variety of geometries known as conformations by the rotation and bending of its bonds.

Conformational isomerism, often known as stereoisomerism, is a type of stereoisomerism in chemistry in which the isomers can be changed to one another simply by rotations about formally single bonds. Different conformations refer to any two arrangements of atoms in a molecule that differ by rotation about a single bond, whereas conformations that correspond to local minima on the potential energy surface are more specifically known as conformational isomers or conformers.

As a result, conformational isomers differ from other classes of stereoisomers (such as configurational isomers), where interconversion entails the necessary breaking and reformation of chemical bonds.

Thus, the statement, The different geometries that a molecule can attain by bond rotations and bends are called conformations is TRUE

The wait time required for 200 people are in line would be 40min.

Given that:

wait time to ride the ferris wheel for 75 people is 15 minutes.

we have given 200 people that are in line to ride.

for each person in line from the beginning is an additional 0.2 wait time.

so, the number of people in line n times = 0.2 = wait time.

Therefore,

                 [tex]\frac{15\ min}{75 \ people}=0.2\frac{min}{people} \\\\wait \ time = n*0.2\frac{min}{people} \\\\wait\ time = (200)*0.2\frac{min}{people}\\\\wait\ time = 40 min[/tex]

Answer:

Answer:

The most appropriate method for solving the first system of equations would be elimination. This can be done by adding the two equations together, which will eliminate one of the variables and leave us with an equation in terms of the remaining variable. We can then solve for the value of this variable and substitute it back into one of the original equations to find the value of the other variable.

For the second system of equations, substitution would be the most appropriate method. This is because one of the equations can be rearranged to solve for the value of one of the variables, which can then be substituted into the other equation. This will eliminate one of the variables and allow us to solve for the value of the remaining variable.

For the third system of equations, graphing would be the most appropriate method. This is because both equations are in the form "y = mx + b," which is the standard form of a linear equation. We can graph both equations on the same coordinate plane and find the point of intersection, which will give us the values of both variables.

The probability is the odds thus the probability it will rain today will be 5/9.

Probability is the concept that describes the likelihood of an event occurring.

Probability is also known as chance because, if you flip a coin, the possibilities that it will land on its head or tail are just chances that either a head will show up or not.

The odds of rain today are 5:9

Odds will be the same as probability because the probability is the same as chance.

Probability = 5/9

Hence "Since probability equals odds, the likelihood that it will rain today is 5/9.".

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

The correct options are:

The probability when the value of W = 1 is 0.1 , probability when the value of W = 10 is 0.2 and probability when the value of W = 25 is 0.7  .

In the question ,

In statistics, a regression equation is used to determine whether or not there is a relationship between two sets of data. If you measure a child's height every year, you might discover that they grow about 3 inches per year. A regression equation can be used to model that trend (growing three inches per year). In fact, most things in the real world (from gas prices to hurricanes) can be modelled mathematically, allowing us to forecast future events.

Regression equations can assist you in determining whether your data can be fit to an equation. This is extremely useful if you want to make predictions based on your data, whether they are future predictions or indications of past behaviour.

Given,

Regression equation is y=11-038x

Observed value of y = 9

predicted value of y can be determined by substituting x=2 in the equation

y=11-0.8(2)=11-1.6=9.4

The residual can be calculated by formula,

residual = observed value - predicted value

residual = 9 - 9.4
