The minimum score an applicant needs to qualify for the final stage 1056

In this question we have been given that students sit for a special standardized test and score on the top 10% of the test to be admitted into the final stage of hiring. the mean of the score of the test is 800 and the population standard deviation is known to be 200.

We need to find the minimum score an applicant needs to qualify for the final stage.

Z score is given by:

z = (raw score - mean) / standard deviation

here: mean = 800

and a standard deviation = 200

P(z > c) = 10% = 0.1

1 - P(z < c) = 0.1

P(z < c) = 0.9

P(z < c) = 1.282

So, substituting these values in above formula,

1.282 = (x - 800)/200

x - 800 = 256.4

x = 1056.4

x ≈ 1056

Therefore, the lowest possible score to qualify in the top 10% is approximately 1056

Answer:

150

Step-by-step explanation:

5/6= ?/180

We can use cross-products to solve.

5 * 180 = 6 * ?

Divide each side by 6.

5 * 180/6 = ?

5 * 30 = ?

150

The missing number is 150.

Answer:

150/180

Step-by-step explanation:

Solution by Cross Multiplication;

The equation:

\(\frac{5}{6} = \frac{x}{180}\)

The cross-product is:  

5(180)  =  6(x)

Solving for x:

The measure of angle A is 21°

The sine rule states that if a, b and c are the lengths of the sides of a triangle, and A, B and C are the angles in the triangle; with A opposite a, etc., then a/sinA=b/sinB=c/sinC.

Sine rule is used to find the measure of unknown angle or side of a. triangle.

Using sine rule to find the unknown angle;

a/sinA = b/sinB

19/sinA = 45/sin122

45sinA = 19sin122

45sinA = 19 × 0.840

45sinA = 16 .112

sinA = 16.112/45

sinA = 0.358

A = sin^{-1} 0.358

A = 21° ( nearest degree)

Therefore the measure of angle A is 21°.

Answer:

\(x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}\)

Step-by-step explanation:

Quadratic formula: \(x=\frac{-b\±\sqrt{b^2-4ac} }{2a}\) when the equation is \(0=ax^2+bx+c\)

The given equation is \(1=-2x+3x^2+1\). Let's first arrange this so its format looks like \(y=ax^2+bx+c\):

\(1=-2x+3x^2+1\)

\(1=3x^2-2x+1\)

Subtract 1 from both sides of the equation

\(1-1=3x^2-2x+1-1\\0=3x^2-2x+0\)

Now, we can easily identify 3 as a, -2 as b and 0 as c. Plug these into the quadratic formula:

\(x=\frac{-b\±\sqrt{b^2-4ac} }{2a}\\x=\frac{-(-2)\±\sqrt{(-2)^2-4(3)(0)} }{2(3)}\)

The uniform model assumes equal probabilities for all values within a given range when there is no reason to believe that any X-values are more likely than others.

In statistics, the uniform model assumes that all values within a given range have an equal probability of occurring. This means that there is no preference or bias towards any specific value within the range. The uniform distribution is often represented by a rectangular shape, where the probability of any particular value occurring is constant.

The uniform model is typically used when there is no reason to believe that any X-values are more likely than others. This means that there is no prior information or evidence indicating that certain values are more probable or occur more frequently than others. In other words, there is no specific distribution or pattern in the data that suggests any particular value is more likely to occur.

The correct interpretation of the logarithm of a number L to any base M is that ln_M(N) = L, where N = M^L. This corresponds to option B.

In mathematics, the logarithm function is the inverse operation of exponentiation. It helps us find the power to which a base must be raised to obtain a certain number. In this case, ln_M(N) = L means that when we take the logarithm of N with base M, the result is L.

To clarify, N represents the number we want to find the logarithm of, M is the base of the logarithm, and L is the power to which the base M must be raised to obtain N. So, N = M^L represents the exponential form of the equation.

Option B, ln_M(N) = L N = L^M, correctly captures this relationship and provides the appropriate interpretation of the logarithm of a number L to base M.

Asymptotic independence refers to the property where the sum and maximum of dependent random variables become asymptotically independent as the number of variables increases. This concept has applications in high-dimensional tests.

In statistical analysis, dependence between random variables can pose challenges when performing hypothesis testing, particularly in high-dimensional settings where there are a large number of variables. However, under certain conditions, the sum and maximum of dependent random variables can exhibit asymptotic independence, which can be leveraged in high-dimensional tests.

Asymptotic independence occurs when the dependence between variables weakens as the number of variables increases. Specifically, if the correlation between random variables decreases to zero as the number of variables increases, the sum and maximum of these variables can be considered asymptotically independent.

This property has important implications for high-dimensional tests, where controlling the family-wise error rate (FWER) or false discovery rate (FDR) is crucial. High-dimensional tests involve simultaneously testing multiple hypotheses, often in scenarios where the dimensionality (number of variables) is large. Asymptotic independence between the sum and maximum of dependent variables allows for the application of theoretical results that hold for independent variables, thereby facilitating the development of valid statistical tests in high-dimensional settings.

Calculations for asymptotic independence involve analyzing the behavior of correlation coefficients as the number of variables increases. By examining the limit of the correlation coefficients as the number of variables approaches infinity, it can be determined if the dependence weakens and asymptotic independence is achieved.

Asymptotic independence refers to the property where the sum and maximum of dependent random variables become asymptotically independent as the number of variables increases. This property has applications in high-dimensional tests, enabling the development of valid statistical tests in scenarios with a large number of variables. By understanding the concept of asymptotic independence, researchers can leverage this property to address the challenges posed by dependence in high-dimensional settings and make accurate statistical inferences.

Answer:

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

Step-by-step explanation:

Geometrically speaking, the perimeter of a rectangle (\(p\)) is:

\(p = 2\cdot b + 2\cdot h\) (1)

Where:

\(b\) - Base of the rectangle.

\(h\) - Height of the rectangle.

Let suppose that the base of the rectangle is the line segment between (4, -3) and (-1, -3). The length of the base is calculated by Pythagorean Theorem:

\(b = \sqrt{[(-1)-4]^{2}+[(-3)-(-3)]^{2}}\)

\(b = 5\)

If we know that \(p = 18\) and \(b = 5\), then the height of the rectangle is:

\(2\cdot h = p-2\cdot b\)

\(h = \frac{p-2\cdot b}{2}\)

\(h = \frac{p}{2}-b\)

\(h = 4\)

There are two possible solutions for the other two vertices of the rectangle:

(i) (4, 1), (-1, 1), (ii) (4, -7), (-1, -7)

From the question, we are to determine the statement that describes the shape of the barrier

From the given information,

The barrier is 2.5 feet from the tomato plant in every direction.

This can be likened to a circle that has a radius of 2.5 feet.

Recall: Radius of a circle is the distance from the center of the circle to any point on it's circumference

If radius of a circle is 2.5 feet, the diameter will be 2 × 2.5 feet = 5 feet

Hence, the shape of the barrier is a circle with a diameter of 5 feet. The correct option is the last option-  A circle with a diameter of 5 feet
