The z-score of a person who scored 330 on the exam is approximately 2.7.

To find the z-score of a person who scored 330 on the exam, we can use the formula for calculating the z-score:

z = (x - μ) / σ

where:

z is the z-score

x is the raw score (330 in this case)

μ is the mean (195 in this case)

σ is the standard deviation (50 in this case)

Substituting the values into the formula, we get:

z = (330 - 195) / 50

z = 135 / 50

z = 2.7

The z-score of a person who scored 330 on the exam is 2.7.

The z-score measures the number of standard deviations a particular data point is away from the mean.

In this case, a z-score of 2.7 indicates that the person's score of 330 is 2.7 standard deviations above the mean score of 195.

The z-score is useful for comparing data points across different normal distributions or for determining the relative position of a data point within a distribution.

A positive z-score indicates a value above the mean, while a negative z-score indicates a value below the mean.

In this context, a z-score of 2.7 suggests that the person's score is relatively high compared to the average performance on the exam.

Answer:

  1 = (x/11)² +24y²/605

Step-by-step explanation:

You want the the equation of an ellipse through the point (1, 5) with ends of its major axis at (±11, 0).

The ellipse equation will have the form ...

  (x/11)² + (y/b)² = 1

for some value 'b' that causes (x, y) = (1, 5) to be a solution to this equation.

Using the given point and solving for b (or b²), we have ...

  (1/11)² +(5/b)² = 1

  25/b² = 1 -1/121 = 120/121

Inverting this equation and multiplying by 25, we have ...

  b² = 605/24

Using this value for b², we can write the equation of the ellipse as ...

  [tex]\boxed{1=\dfrac{x^2}{121}+\dfrac{24y^2}{605}}[/tex]

The average of the four odd whole numbers (12) is greater than the average of the four even whole numbers (11).

To determine which average is greater, let's calculate the average of the four even whole numbers from 8 to 15 and the average of the four odd whole numbers from 8 to 15.

The even numbers from 8 to 15 are 8, 10, 12, and 14.

To find their average, we sum them and divide by 4:

Average of even numbers = (8 + 10 + 12 + 14) / 4 = 44 / 4 = 11.

The odd numbers from 8 to 15 are 9, 11, 13, and 15.

Similarly, we find their average:

Average of odd numbers = (9 + 11 + 13 + 15) / 4 = 48 / 4 = 12.

Comparing the two averages, we find that the average of the four odd whole numbers from 8 to 15 is greater than the average of the four even whole numbers from 8 to 15.

The expected value of the game is -1/2.

This means that, on average, the player can expect to lose 1/2 dollar per game in the long run.

To find the expected value of the game, we need to calculate the probability of each outcome and multiply it by its associated value, then sum up the results.

In a standard deck of playing cards, there are 26 red cards (13 hearts and 13 diamonds) and 26 black cards (13 clubs and 13 spades).

Since drawing a card is a random event, the probability of drawing a red card is the number of favorable outcomes (red cards) divided by the total number of possible outcomes (52 cards).

Probability of drawing a red card:

P(Red) = Number of red cards / Total number of cards = 26/52 = 1/2

Now, let's calculate the expected value:

Expected Value = (Probability of winning) × (Value of winning) + (Probability of losing) × (Value of losing)

In this game, if the player wins, they gain 1 dollar, and if they lose, they lose 2 dollars.

Expected Value = (1/2) × (+1) + (1/2) × (-2) = 1/2 - 2/2 = -1/2

The general solution to the differential equation -√3 cscθ = 2 is θ = 2π/3 + nπ.

To find the general solution to the trigonometric equation -√3 cscθ = 2, where n is an integer, we need to solve for θ.

Let's start by rewriting the equation:

-√3 cscθ = 2

Since cscθ is the reciprocal of sinθ, we can rewrite the equation as:

-√3 / sinθ = 2

To solve for θ, we can take the reciprocal of both sides:

sinθ / -√3 = 1/2

Next, we can take the reciprocal of both sides again:

-√3 / sinθ = 2

Now, we can find the values of θ that satisfy this equation. The general solution is given by:

θ = arcsin(-√3/2) + nπ

θ = 2π/3 + nπ

The height of the building is 242.59 feet.

Let's denote the height of the building as h.

angle of elevation is 35 degrees.

Using the tangent function,

tan(35°) = h / x

h = x tan(35°)

From the second observation point, which is 150 feet closer to the building,

The adjacent side is now (x - 150) since we moved closer to the building.

So, tan(51°) = h / (x - 150)

In the coordinate plane, the vertices of triangle PAT are P(-1,-6), A(-4,5), and T(5,-2) forms an isosceles triangle.

To prove that triangle PAT is an isosceles triangle, we need to show that at least two sides of the triangle are congruent.

Let's calculate the distances between the vertices:

Distance between P and A:

PA = √[(x₂ - x₁)² + (y₂ - y₁)²]

= √[(-4 - (-1))² + (5 - (-6))²]

= √[9 + 121]

= √130

Distance between P and T:

PT = √[(5 - (-1))² + (-2 - (-6))²]

= √[(5 + 1)² + (-2 + 6)²]

= √[36 + 16]

= √52

= 2√13

Distance between A and T:

AT = √[(5 - (-4))² + (-2 - 5)²]

= √[(5 + 4)² + (-2 - 5)²]

= √130

We can see that PA = AT = √130, and PT = 2√13.

Since PA = AT, we have shown that two sides of the triangle are congruent.

Therefore, triangle PAT is an isosceles triangle.

To find the probability of randomly selecting a Spade or a face card given it's black, we need to determine the number of favorable outcomes and the total number of possible outcomes. Let's break it down step by step:

Step 1: Determine the number of favorable outcomes:

First, let's determine the number of black cards in a deck of 52 cards. In a standard deck, there are 26 black cards, which include 13 Spades (black suits) and 13 Clubs (black suits). Therefore, we have 26 favorable outcomes.

Next, we need to determine the number of face cards that are black. In each suit, there are three face cards: Jack, Queen, and King. So, there are a total of 12 face cards in the deck, out of which 6 are black (2 black face cards in each black suit). Therefore, we have 6 additional favorable outcomes.

Step 2: Determine the total number of possible outcomes:

In a standard deck of 52 cards, there are 52 possible outcomes.

Step 3: Calculate the probability:

The probability is the ratio of favorable outcomes to the total number of possible outcomes.

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = (26 + 6) / 52

Probability = 32 / 52

Probability = 8 / 13

So, the probability of randomly selecting a Spade or a face card given it's black is 8/13.

Please note that this calculation assumes that the selection is random and the deck of cards is well-shuffled.

Answer:

[tex]\frac{9}{48}[/tex]

Step-by-step explanation:

the 3 on the numerator has been multiplied by 3 to get the 9 on the numerator on the right.

the same operation must be applied to the 16 on the denominator of the fraction.

16 × 3 = 48

then

[tex]\frac{3}{16}[/tex] = [tex]\frac{3(3)}{16(3)}[/tex] = [tex]\frac{9}{48}[/tex]

We have shown that the path of a moving point with velocities u + ey and v + ex, parallel to the axes of x and y, is either a line (when v - [tex]e^2[/tex] ≠ 0) or a horizontal line (when v - [tex]e^2[/tex] = 0), both of which are conic sections.

To show that the path of a moving point parallel to the axes of x and y with velocities u + ey and v + ex is a conic section, we can analyze the motion of the point using the principles of calculus and conic sections.

Let's denote the position of the point at any given time t as (x, y). We are given that the velocities along the x and y axes are u + ey and v + ex, respectively. This means that the derivatives of x and y with respect to time, dx/dt and dy/dt, can be expressed as:

dx/dt = u + ey

dy/dt = v + ex

Now, let's integrate these expressions to obtain x and y as functions of t. Integrating dx/dt with respect to t gives:

x = ut + eyt + C1

Similarly, integrating dy/dt with respect to t gives:

y = vt + ext + C2

Where C1 and C2 are constants of integration.

Now, we can eliminate the parameter t by expressing t in terms of x and y. From the equation y = vt + ext + C2, we can solve for t:

t = (y - ext - C2) / v

Substituting this value of t into the equation for x, we get:

x = u[(y - ext - C2) / v] + ey[(y - ext - C2) / v] + C1

Simplifying this equation, we obtain:

vx - u - evx + ue + vy - [tex]e^2[/tex]x - eyC2 = C1v

Rearranging the terms, we get:

vx - vy + ue + evx - [tex]e^2[/tex]x = C1v + eyC2 - u

Let's define new constants A = ue + ev and B = C1v + eyC2 - u. The equation then becomes:

(v - [tex]e^2[/tex])x + (u + ev)y = A + B

This equation is in the standard form of a conic section, specifically a line. However, we can manipulate this equation further to reveal other possible conic sections.

Let's consider the case when v - [tex]e^2[/tex] ≠ 0. In this case, we can divide both sides of the equation by v - [tex]e^2[/tex], yielding:

x + [(u + ev)/(v - [tex]e^2[/tex])]y = (A + B)/(v - [tex]e^2[/tex])

Now, let's define another constant C = (u + ev)/(v -[tex]e^2[/tex]) and rewrite the equation as:

x + Cy = D

Where D = (A + B)/(v - [tex]e^2[/tex]).

This equation represents a line in the x-y plane.

On the other hand, if v - [tex]e^2[/tex] = 0, the equation becomes:

0x + (u + ev)y = A + B

This simplifies to:

(u + ev)y = A + B

Which is a horizontal line parallel to the x-axis.

Therefore, we have shown that the path of a moving point with velocities u + ey and v + ex, parallel to the axes of x and y, is either a line (when v - [tex]e^2[/tex] ≠ 0) or a horizontal line (when v - [tex]e^2[/tex] = 0), both of which are conic sections.

The reason that the point (3, 5) is not a solution to the given inequality is given below.

We are given that;

y > 2x + 1

Now,

The inequality y > 2x + 1 can be graphed by first graphing the boundary line y = 2x + 1. Since the inequality is strict (y >), we draw a dashed line to indicate that points on the line are not solutions to the inequality. Then, we shade the region above the line to indicate all points that satisfy the inequality.

If we have (3,5) as a point, we can see that it lies on the boundary line

y = 2x + 1.

Since the inequality is strict (y >), points on this line are not solutions to the inequality
