Faults are planar features in rocks where the two sides move past each other due to tectonic forces. However, not all planar features in rocks are faults, as there are other types of planar features that do not involve movement. A planar feature that does not involve movement is called a joint.

A planar feature refers to a surface or boundary within a rock that has a relatively consistent orientation or direction. These features can be caused by a variety of geological processes, such as deformation, metamorphism, or sedimentation. Some examples of planar features in rocks include bedding planes, foliation, and cleavage.

A fault, in particular, is a type of planar feature that forms when tectonic forces cause two sides of a rock to move past each other. This movement can be horizontal, vertical, or a combination of both. Faults can range in size from small fractures in the rock to large features that extend for kilometers. They are a common feature in regions where tectonic forces are actively shaping the Earth's crust, such as along plate boundaries or in areas with active volcanism.

On the other hand, a planar feature that does not involve movement is called a joint. Joints are fractures in rocks that do not result in any significant displacement of the rock on either side of the fracture. They can be caused by a variety of factors, such as cooling and contraction of magma or shrinkage of sediments. Joints can be important in geology because they can influence the way that rocks weather and erode over time.

In summary, a planar feature refers to a surface or boundary within a rock that has a relatively consistent orientation or direction. While faults are a type of planar feature that involves movement between two sides of a rock, joints are planar features that do not involve any significant displacement of the rock on either side of the fracture. Understanding these different planar features is important in geology, as they can provide insight into the geological history of a region and can be used to predict future geological activity.

a function means that for every input (value of x), there is only one output (value of y)

y can repeat, x cannot (unless it's with the same y value)

eg:

{(1,2), (1,3), (3,2)} is not a function because 1 has two outputs

but if it was

{(1,2), (2,3), (3,2)} it would be a function. It doesn't matter that 2 repeats in the y coordinate

The solution to the equation cos(x + 2π/3) = √2/2 over the interval

(0, 2π) is [7π/12, 3π/4]

A periodic function has a range that is determined for a fixed interval and a domain that includes all real number values.

Any function that has a positive real integer p such that f (x + p) = f (x), with all x being real values, is said to be periodic.

The given function is cos(x + 2π/3) = √2/2 over the interval (0, 2π).

(x + 2π/3) = cos⁻1(√2/2).

x + 2π/3 = π/4  or 21π/12   (As cos is +ve on I and IV)

Now,

x + 2π/3 = π/4.

x = π/4 - 2π/3.

x = (3π - 8π)/12.

x = - 5π/12.

x = π - 5π/12.

x = (12π - 5π)/12.

x = 7π/12.

And,

x + 2π/3 = 21π/12.

x = 21π/12 - 2π/2.

x = (21π - 12π)/12.

x = 9π/12.

x = 3π/4.

The probability that a student is in 4th grade given that they did not choose popular as the most important trait is 0.5 or 50%.

The probability is a concept used in statistics that measures the likelihood of an event occurring.

Let's call the event of a student being in 4th grade as A and the event of a student not choosing popular as the most important trait as B. We can find the probability of A and B happening together by dividing the number of students who are in 4th grade and did not choose popular by the total number of students. This can be represented as

P(A and B) = P(A | B) = (75 / 250) = 0.3.

Next, we can find the probability of B happening by dividing the number of students who did not choose popular by the total number of students. This can be represented as

P(B) = (150 / 250) = 0.6.

Finally, we can use Bayes' theorem to find the probability of A given B. Bayes' theorem states that

=> P(A | B) = P(A and B) / P(B).

Therefore,

=> P(A | B) = (75 / 250) / (150 / 250) = 0.3 / 0.6 = 0.5.

The exponential function is [tex]y = 1505.88(0.85)^x[/tex].

The monthly number of defective parts will be less than 500 about 7 months after Jane was hired.

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

To model the monthly number of defective parts, we can use an exponential equation of the form:

[tex]y=a(b)^x[/tex]

Where y is the number of defective parts, x is the number of months after Jane was hired, a is the initial number of defective parts, and b is the common ratio between consecutive months.

To find the values of a and b, use the two data points given -

In the first month, there were 1,280 defective parts, which means that y = 1280 when x = 1.

In the second month, there were 1,088 defective parts, which means that y = 1088 when x = 2.

Substituting these values into the exponential equation -

1280 = a(b)

1088 = a(b)²

Dividing the second equation by the first equation -

1088/1280 = (a(b)²)/(a(b))

0.85 = b

Substituting b = 0.85 into the first equation -

1280 = a(0.85)

1280 = 0.85a

a = 1505.88 (rounded to two decimal places)

So the exponential equation that models the monthly number of defective parts is -

[tex]y = 1505.88(0.85)^x[/tex]

To find when the monthly number of defective parts will be less than 500, we can set y = 500 and solve for x -

[tex]500 = 1505.88(0.85)^x[/tex]

Dividing both sides by 1505.88 -

[tex]0.332 = (0.85)^x[/tex]

Taking the logarithm of both sides (with any base) -

log(0.332) = x log(0.85)

Dividing both sides by log(0.85) -

x = log(0.332) / log(0.85)

x ≈ 6.87

Therefore,  the monthly number of defective parts will be less than 500 about 7 months after Jane was hired.

The probability of being dealt two aces and one of them being the ace of spades is 1 in 221, or 0.45%.

The probability of being dealt two aces and one of them being the ace of spades is 1/221. This is because the chance of the first card being the ace of spades is 1/52 and the chance of the second card being an ace, given that the first card is an ace, is 3/51. Thus, the probability of both cards being aces and one of them being the ace of spades is 1/221.

Mathematically, this can be expressed as P(Ace of Spades, Ace) = P(Ace of Spades) x P(Ace|Ace of Spades) = (1/52) x (3/51) = 1/221.

This means that the probability of being dealt two aces and one of them being the ace of spades is 1 in 221, or 0.45%.

A high standard deviation indicates greater variability in the data set. A low standard deviation indicates lower variability in the data set.

A standard deviation is a measure of how spread out the values in a data set are. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean. A high standard deviation indicates that the values in the data set are far from the mean and spread out over a large range of values. This suggests that there is a large amount of variation and diversity in the data. On the other hand, a low standard deviation indicates that the values in the data set are close to the mean and spread out over a smaller range of values. This suggests that there is less variability and diversity in the data. A standard deviation of zero indicates that all values in the data set are the same. This suggests that there is no variation or diversity in the data. No one set of data is more accurate than another; accuracy depends on the context and purpose of the data. For example, if the goal is to identify trends or outliers, a data set with a high standard deviation may be more useful than one with a low standard deviation.
