A person with a Z-score of -0.42 would have a raw score of 992.4 on the SAT taken in 2018.

The standard deviation is a measure of how much the data varies from the mean. A Z-score is a standardized value that represents the number of standard deviations a raw score is from the mean.

To find the raw score given a Z-score, we can use the following formula:

raw score = mean + Z-score * standard deviation

For the mean composite score of 1068 and a standard deviation of 180, we can plug in the values for the Z-score of -0.42:

raw score = 1068 + (-0.42) * 180

raw score = 1068 - 75.6

raw score = 992.4

Note: The Z-score of -0.42 indicates that the raw score is 0.42 standard deviations below the mean.

The other polygon has a 108 [tex]ft^2[/tex] area.

We are given the area overall (27 [tex]ft^2[/tex]) and the length of one side (3 ft) for the polygon on the left. With this knowledge, we can calculate the other side's length, which is 9 feet. I calculated this by multiplying 27 [tex]ft^2[/tex] by 3 ft, which gave me the answer of 9 ft.

We now need to locate the opposite side of the polygon on the right in order to calculate its area. Given that 3 * 2 = 6, it appears as though there is a scale factor of 2 between the two polygons. Knowing that the bottom side of the polygon on the left is nine, we may calculate the bottom side of the polygon on the right by multiplying nine by two. 9 × 2 = 18.

Now that we know the dimensions of the polygon on the right, we can calculate its area.

The other polygon's area is 107 [tex]ft^2[/tex] since 6*18 = 107.

What are expressions?

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.

e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

A scale of 1:900,000 is 36 times smaller than a scale of 1:24,000.

This can be expressed mathematically as a ratio: 1:900,000 = 1:24,000 / 36. To calculate the scale factor between two maps, divide the denominator of the larger scale by the denominator of the smaller scale. In this example, the scale factor is 36.

A scale of 1:900,000 means that one unit on the map represents 900,000 units of the same type in the real world. For example, one centimeter on the map could represent 900,000 centimeters in real life, or 9 kilometers. A scale of 1:24,000 would mean that one unit on the map represents 24,000 units of the same type in the real world. For example, one centimeter on the map could represent 24,000 centimeters in real life, or 0.24 kilometers.

The scale factor is the number that is used to compare the size of one map to another. In this example, a map with a scale of 1:900,000 is 36 times smaller than a map with a scale of 1:24,000. This means that the features on the 1:900,000 map are 36 times smaller than the same features on the 1:24,000 map. Therefore, the 1:900,000 map is not as detailed as the 1:24,000 map.

The average value is the intersection point between the function and the line, which is at (0,1+C).

The average value of a function on an interval can be calculated using the following formula: Average Value = (1/b-a)∫a b f(x)dx. In this case, the function is f(x) and the interval is [0,1]. To calculate the average value, we must first calculate the integral of the function on the given interval. The integral of f(x) is nx^n-1 + C, where C is a constant. Using the fundamental theorem of calculus, we can evaluate the integral from 0 to 1 to be 1 + C.

The average value of the function on the given interval is then (1/1-0)∫0 1 (1+C)dx, which simplifies to 1+C. Therefore, the average value of the function on the given interval is 1 + C.

Graphically, the average value of the function on the given interval can be seen by plotting the graph of the function, which is a parabola with a vertex at (0,0), and a line at y=1+C. The average value is the intersection point between the function and the line, which is at (0,1+C).

We can calculate the magnitude and coordinate direction angle of f3 using the vector triangle method.

We assume that the coordinate direction angle of f1 is 0° and the coordinate direction angle of f2 is 90°.

Using the law of cosines, we can determine the magnitude of f3, which is 6.403N:

f3^2 = f1^2 + f2^2 -2f1f2cos180°

f3^2 = 5^2 + 8^2 -2(5)(8)cos180°

f3^2 = 25 + 64 -80

f3^2 = 49

f3 = 6.403N

We can then use the law of sines to determine the coordinate direction angle of f3, which is 247.9°:

Answer: 3 - 4i

Step-by-step explanation:

For the given polynomial p(x) , if 3 +4i is a root then, 3 - 4i is also the root of p(x).

Consider the given polynomial equation p(x) = 0 It is given that the polynomial P(x) has one root 3 + 4i .

According to complex conjugate theorem,  if V is a polynomial and x + iy is a root of given polynomial then  its conjugate x - iy is also the root of the polynomial.

Thus, for the given polynomial p(x)  if 3 +4i is a root then, 3 - 4i is also the root of p(x).

If a polynomial equation P(x) = 0 has (3 + 4i) as a solution, the other solution it must have (3 - 4i).

What is a polynomial?

Polynomial is formed composed of the phrases Nominal, which means "terms," and Poly, which means "many." An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.

Conjugate complex numbers are those that only differ in the imaginary part's sign.

a + bi and a - bi, where a and b are real numbers, are generally conjugate, as are, for instance, 2 + 3i and 2 - 3i, -5 - 7i and -5 + 7i, and so on.

Due to the fact that their output is always a genuine number.

The general case is -

= (a + bi)(a - bi)

= a² - abi + abi - (b²)(i²)

= a² + b²

The real example is -

= (2 + 3i)(2 - 3i)

= 2² + 3²

= 4 + 9

= 13

Complex roots for a polynomial equation P(x) = 0 with real coefficients are always represented as conjugate pairs.

So, the following equation must contain (3 - 4i) as a second root if the coefficients are real.

Therefore, P(x) has second root (3 - 4i).

If the liquidity premium theory of the term structure of interest rates holds, 0.498% is the liquidity premium for year 2.

Any additional compensation that is necessary to attract investment in assets that cannot be quickly and effectively converted into cash at fair market value is known as a liquidity premium. Because it is more difficult to sell than a short-term bond, a long-term bond, for instance, will have a higher interest rate. According to the principle of the liquidity premium, bond investors favour short-dated assets that are highly liquid and have a short sales cycle over those that are longer-dated. According to another tenet of the theory, fluctuations in interest rates provide investors with compensation for greater pricing and default risks.
