There are three values in the interval [60,65) which satisfy the mentioned criteria.

The number of times, a data point occurs in the data set is called its frequency .

For eg - If I visit market twice a week, so my frequency of going to the market in a week is 2.

Now, here given 4 data column and data points in interval [60,65) means that 60 and less than 65 will included included but 65 not included in interval i.e. its an open interval at 65 and a closed interval at 60.

So, from the given data we can say that the values  (64.1, 60, 64.83) are lying in the interval [60,65).

So, the frequency is 3.

The point on the x-axis that lies on the line passing through point C and parallel to line AB is (4, 0).

A line that is parallel to line AB and passes through point C has the same slope as line AB. The slope of line AB can be found using the formula:

m = (y2 - y1) / (x2 - x1),

where (x1, y1) and (x2, y2) are the coordinates of the two points on the line.

In this case, (x1, y1) = (negative 4, 0) and (x2, y2) = (2, negative 3).

Substituting these values into the formula, we get:

m = (-3 - 0) / (2 - -4) =  -3 / 6 = -1/2

Since the slope of line AB is -1/2,

the slope of the line through point C and parallel to line AB is also -1/2.

A line with slope -1/2 and passing through (negative 2, 2) has the equation:

y - 2 = -1/2 (x - -2),

Rearranging this equation to solve for y, we get:

y = -1/2 x + 2

The x-axis has y-coordinate 0, so substituting 0 for y in the equation, we get:

0 = -1/2 x + 2

Solving for x, we get:

x = 4

hence the point is (4, 0)

The relationship between x and y is that x is equal to twice the value of y.

The relationship between x and y can be expressed as a logarithmic equation. The first equation states that Log(c) = X/2, where c is a constant. The second equation states that Log(c^2) = Y. We can solve for the relationship using the two equations given. For equation 1, we can isolate X on one side of the equation to get X = 2*Log(c). For equation 2, we can isolate Y on one side of the equation to get Y = Log(c^2). Plugging the expression for X into equation 2, we get Y = Log(c^2) = Log(c)*2 = 2*Log(c) = X. Therefore, the relationship between X and Y is X = Y.To calculate the relationship between x and y, we can use the power law equation, which states that c^(x/2) = c^y. This can be rewritten as x/2 = y, so we can conclude that the relationship between x and y is x = 2y. Therefore, the relationship between x and y is that x is equal to twice the value of y.

The statement is True. Mean normalization scales data to have a mean of 0, which allows the gradient descent algorithm to more quickly identify the optimum point.

Mean normalization is a feature scaling technique used to speed up the learning process of gradient descent algorithms. It works by mapping the values of a dataset to a range of [-1, 1], or [0, 1], by subtracting the mean from each data point and dividing by the standard deviation. This scaling process helps to reduce the impact of the outliers and normalize the data, allowing the gradient descent algorithm to more quickly converge on the optimal solution.

The probability that it takes 10 circuit boards to be inspected before a defective board is found is approximately 0.16777216%.

The probability that it takes 10 circuit boards to be inspected before a defective board is found can be calculated using the cumulative distribution function (CDF) of the geometric distribution. The CDF of the geometric distribution is given by the formula:

where p is the probability of success (in this case, the probability of finding a defective circuit board) and k is the number of trials (in this case, the number of circuit boards inspected). Since the probability of finding a defective circuit board is 0.02, we can calculate the CDF as follows:

Rhoxy is the chemical symbol for Rhodium (Rh).

Rhodium is a transition metal found in group 9 of the periodic table, and its atomic number is 45. Its atomic mass is 102.90550 g/mol. Its atomic radius is 1.36 angstroms and its oxidation state is +3.

Rhoxy can be calculated by taking the atomic mass of Rhodium and converting it to moles. This is done by dividing the atomic mass of Rhodium by the molar mass constant, which is 1.00794 g/mol. This results in 0.1022 moles of Rhodium. The formula for moles of a substance is n = m/M, where n is the moles, m is the mass of the substance, and M is the molar mass constant.

To calculate the amount of Rhoxy, divide the moles of Rhodium by Avogadro’s number (6.02 x 10^23). This results in 1.68 x 10^-24 moles of Rhoxy. The formula for this calculation is n = n/N, where n is the moles of the substance, and N is Avogadro’s number.
