The function that is not a function for all values of x is f(x) = -x13.

A function is a relation between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. For instance, y = x^2 is a function since every x is related to exactly one y.The function that is not a function for all values of x is f(x) = -x13.

The function f(x) = -x13 is not a function for all values of x because the function does not exist for negative values of x raised to an odd exponent. This is because the result of negative values raised to odd exponents will always be a negative value, which means the function would not be well-defined for negative values. However, the function does exist for all other values of x.

Step-by-step explanation:

With 60 random samples, the auditor should communicate the finding of the material misstatement to the appropriate level of management.

What is random sampling?

In statistics, sampling is a way of picking a subset of the population from which to draw statistical conclusions. The characteristics of the entire population may be approximated from the sample. Market research sampling may be divided into two types: probability sampling and non-probability sampling.

Now,

Based on the information provided, the auditor should evaluate whether the overstatement of $4,000 in the sample is indicative of a material misstatement in the population of purchase orders.

To do this, the auditor can calculate the projected misstatement and compare it to the tolerable misstatement for purchases.

The projected misstatement can be calculated as follows:

Projected misstatement = (Total population / Sample size) x Sample misstatement

Projected misstatement = (1,200 / 60) x $4,000

Projected misstatement = $80,000

Since the projected misstatement of $80,000 exceeds the tolerable misstatement of $50,000, the auditor should conclude that there is a material misstatement in the population of purchase orders.

As the materiality threshold of the company is $65,000, the auditor should communicate the finding of the material misstatement to the appropriate level of management and consider adjusting the financial statements accordingly. The auditor may also need to perform additional audit procedures to further evaluate the extent of the misstatement and identify the cause of the overstatements.

Optically active compounds can rotate plane-polarized light in

A - Clockwise rotation

B - Counterclockwise rotation

C - Dextrorotatory

D - Levorotatory

Optically active compounds can rotate the plane of polarization of light, which can be either clockwise or counterclockwise. The direction of rotation is usually expressed as either dextrorotatory (abbreviated as +) or levorotatory (abbreviated as -), depending on whether the compound rotates the plane of polarization to the right or left, respectively.

For example, a compound that rotates the plane of polarization to the right (clockwise) is said to be dextrorotatory (+), while a compound that rotates the plane of polarization to the left (counterclockwise) is said to be levorotatory (-).

Therefore, A corresponds to clockwise rotation, B corresponds to counterclockwise rotation, C corresponds to dextrorotatory, and D corresponds to levorotatory.

By answering the above question, we may state that  Given that they carry their lunch to work, the probability that a randomly selected physical therapist would not use the gym membership is 2/7.

Mathematicians use probability theory to determine the chance that an event will occur or a statement is true. A probability of about 0 reflects how probable an event appears to occur, whereas a risk is a value between 0 and 1, where 1 suggests certainty. Probability is a mathematical representation of the likelihood that a specific event will take place. Other ways to express probabilities are as integers between 0 and 1 or as percentages between 0% and 100%. the ratio of events among equally likely options that lead to a certain event to all other outcomes.

Brings lunch to work and doesn't use the gym = P(Brings lunch to work and doesn't use the gym) / P (Brings lunch to work)

So, there is an 18/135 chance that a physical therapist brings lunch to work and does not use their gym membership.

Given that they carry their lunch to work, the likelihood that a physical therapist would not use their gym membership is as follows:

Brings lunch to work | Does not utilise gym membership = 18/135 / 42/135

When we simplify this fraction, we obtain:

Brings lunch to work | Does not utilise gym membership = 2/7

Given that they carry their lunch to work, the likelihood that a randomly selected physical therapist would not use the gym membership is 2/7.

The time the mechanic is away from the shop is 2 hours.

To find the time the mechanic is away from the shop, we need to know either the distance of the round trip or the speed of the mechanic on one of the legs of the trip.

For example, if we know that the distance of the round trip is 30 miles, we can use the formula:

time = distance / speed

where speed is the average speed for the round trip, which is given as 15 miles per hour.

So, the time the mechanic is away from the shop would be:

time = 30 miles / 15 miles per hour = 2 hours

The probability that you will not have to wash the dishes on a given night is 3/5 or 0.6. This is because out of the five children, there are three that are not you, so the probability that one of them will be selected along with you is 3/5.

Alternatively, you could calculate the probability of having to wash the dishes (2/5) and subtract it from 1 to get the probability of not having to wash them, which also gives 3/5 or 0.6.

To calculate the probability that you will not have to wash the dishes on a given night, we need to consider the number of ways you can be excluded from the selection. There are 5 children, and 2 are selected to wash the dishes each night.

There are a total of 10 possible combinations for selecting 2 children out of 5 (using the combination formula: 5! / [2!(5-2)!]). Since you are not included in 4 of those combinations, the probability that you will not have to wash the dishes on a given night is 4 out of 10, or 40%.
