Question: Solve the equation 119 = n - 66 and the options are: a. 53, b.186, c. -185, d. 185

We get that the value of n is option (d) 185 for the equation n - 66 = 119.

We are given an equation:

n - 66 = 119.

An equation is an expression that has an equality sign in between.

For example: 3 x + 3 y = 6 or 7 x + 5 y = 9

We have to solve the equation to find the value of n.

First, we will add 66 to both the sides of the equation.

n - 66 + 66 = 119 + 66 .

Now simplifying the expression, we get that:

n = 119 + 66

Solving the expression to get the value of n:

n = 185

So, option (d) 185 is correct.

Therefore, we get that the value of n is option (d) 185

Answer:

the slope is 5. 5/1

Step-by-step explanation:

Use rise over run to find slope. It is the easiest way to find slope

You rise 5 and 1 to the right

Answer:

The slope is 5

Step-by-step explanation:

So you're just trying to find the slop. We're going to choose 2 points to use which are already marked on the graph.

(0, 2) and (-1, -3)

So to find the slope, we have to find (the difference in y) / (the difference in x)

So we're going to do

-3-2/-1-0

Which is

-5/-1

So since there are two negatives, it become positive, and it'll simplify into 5.

So the slope of the line is 5

The probability of selecting a white-tailed deer that carries the Lyme disease bacteria is 1 in 10,000, or 0.0001. This means that out of every 10,000 white-tailed deer on the east coast, only one is expected to carry the Lyme disease bacteria.

If we assume that each deer in the population has an equal chance of carrying the bacteria, then the probability of selecting a deer that carries the bacteria can be calculated using the formula for probability:

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

In this case, the number of desired outcomes is one (since we want to select a deer that carries the bacteria), and the total number of possible outcomes is the total number of white-tailed deer in the population. Since we don't know the exact number of deer in the population, we can assume that it is very large, so we can use an approximation:

Probability ≈ 1 / (Very large number)

Therefore, the probability of selecting a white-tailed deer from the east coast population that carries the Lyme disease bacteria is very close to 0.0001 or 1 in 10,000.

Answer: 148.5

Step-by-step explanation:

To find the area of this shape, comprised of a rectangle and a triangle, we can find the area of each shape and add them together.

The area of a triangle is 12⋅b⋅h. We are given the triangle's height, 13. The base of the triangle will be the same as the width of the rectangle, which we also know: 11. Now we can calculate the area of the triangle:

A = 1/2⋅b⋅h

A = 12⋅11⋅13

A = 71.5

Now we can find the area of the rectangle, which is l⋅w. The width of the rectangle is 11, which is the same as the base of the triangle; the length is 7:

A =l⋅w

A = 7⋅11

A = 77

Finally, we can add together the area of the triangle and the rectangle to find the total area:

A = 71.5 + 77 = 148.5

The total area of the front of a house will be 148.5.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

A rectangle has a width = 11

The triangle's height = 13

The rectangle's height = 7

Now,

Since, The base of the triangle will be the same as the width of the rectangle.

Hence, The area of rectangle = 7 x 11

                                              = 77

And, The area of triangle = 1/2 x 11 x 13

                                      = 71.5

Thus, The total area of the front of a house = 77 + 71.5

                                                                  = 148.5

Therefore, The total area of the front of a house will be 148.5.

The claim made by the maker of one of the video games is not supported by the given confidence interval. The interval (1.5, 3.8) represents the estimated difference in the mean number of hours per week spent playing the two games.

To determine whether the claim is supported or not, we need to examine the interval. Option A states that the claim is supported because 0 is not contained in the interval. However, the interval (-∞, ∞) contains all possible values, including 0. Therefore, option A is incorrect.

Option B, which mentions the midpoint of the interval being greater than 1, is not a valid criterion for evaluating the claim. The midpoint of the interval does not provide any information about the claim itself. Hence, option B is incorrect.

Option C suggests that the claim is supported because the margin of error for the estimate is less than 1. However, the margin of error is not provided in the question. Therefore, option C cannot be determined based on the given information.

Option D states that the margin of error for the estimate is greater than 1, but the margin of error is not given. Without this information, we cannot evaluate option D.

The correct answer is option E: No, because 0 is not contained in the interval. A confidence interval that does not contain 0 suggests that there is a statistically significant difference in the mean number of hours per week spent playing the two games.

The length of the intercepted arc is (35 - 14√2 ) units.

what is length?

Length is a physical quantity that describes the distance between two points. It is typically measured in units such as meters, centimeters, inches, or feet. In mathematics, length can refer to the size of a geometric object,

In the given question,

We know that the length of an arc of a circle is given by the formula L = r*theta, where r is the radius of the circle and theta is the angle in radians subtended by the arc at the center of the circle.

Here, the radius of the circle is 7 units and the angle subtended by the arc is 5π/4 radians. Therefore, the length of the intercepted arc is:

L = 7*(5π/4) = (35π/4) units.

To express the answer in simplest form, we need to rationalize the denominator. Multiplying both the numerator and denominator by 2√2, we get:

L = (35π/4)(2√2/2√2)

= (35*π*√2)/(8) units.

Finally, simplifying this expression, we get:

L = (35 - 14√2) units.

Therefore, the length of the intercepted arc is (35 - 14√2) units

The given statement "An algorithm is a calculation that determines how long it will take to solve a problem." is False.

An algorithm is not just a calculation that determines how long it will take to solve a problem. An algorithm is a step-by-step set of instructions or a process used to solve a problem or perform a specific task. It is a systematic approach that allows a computer or human to break down a problem into smaller, manageable parts and reach a solution effectively.

Algorithms are the foundation of computer programming and can be applied in various fields such as mathematics, data processing, and problem-solving. They can be simple, like finding the largest number in a list, or complex, like solving a Rubik's Cube.

Efficiency is a key factor in evaluating algorithms. The time and resources required for an algorithm to solve a problem can vary greatly depending on the method used. However, the primary purpose of an algorithm is to provide a clear and concise procedure to reach a solution, rather than just estimating the time needed to solve a problem.

In summary, an algorithm is a well-defined process designed to perform a specific task or solve a problem, rather than just calculating the time required to do so. Its effectiveness depends on its efficiency, accuracy, and the simplicity of the steps involved.

The area of Pac-Man to the nearest tenth mm² is 11.4 mm².

A circle's area is the area that it takes up in a two-dimensional plane. It can be simply calculated using the formula A = r2, (Pi r-squared), where r is the circle's radius.

To find the area of Pac-Man, we need to calculate the area of the sector that corresponds to the angle of his open mouth and subtract the area of the isosceles triangle formed by the two radii of the sector and the chord that represents the straight edge of his mouth.

First, we need to calculate the angle in radians that corresponds to the 60° angle given:

angle in radians = (60/360) x 2π = π/3 radians

Next, we can use the formula for the area of a sector:

Area of sector = (angle in radians / 2π) x πr²

where r is the radius of the circle.

Area of sector = (π/3 / 2π) x π(13mm)² ≈ 84.95 mm²

Now, we need to calculate the area of the triangle. We can use the formula for the area of an isosceles triangle:

Area of triangle = (1/2) x base x height

where the base is the chord that represents the straight edge of Pac-Man's mouth, and the height is half the length of the chord times the sine of half the angle of the mouth opening.

The base of the triangle is given by the formula:

base = 2r x sin(angle/2)

base = 2(13mm) x sin(30°) ≈ 22.52 mm

The height of the triangle is given by the formula:

height = (base / 2) x sin(angle/2)

height = (22.52 mm / 2) x sin(30°) ≈ 6.53 mm

Therefore, the area of the triangle is:

Area of triangle = (1/2) x base x height ≈ 73.5 mm²

Finally, we can subtract the area of the triangle from the area of the sector to get the area of Pac-Man:

Area of Pac-Man ≈ 84.95 mm² - 73.5 mm² ≈ 11.4 mm²

Therefore, the area of Pac-Man to the nearest tenth mm² is 11.4 mm².

The gradient of the tangent at x = 2 is equal to 7. This means that the slope of the tangent line to the curve at that point is 7.

To determine the gradient of the tangent when x = 2, it is necessary to use calculus methods.

This means that we need to find the derivative of the function first, and then substitute x = 2 into it to get the gradient of the tangent at that point. In other words, we are finding the slope of the tangent line to the curve at x = 2.

Suppose that the function is given by y = f(x), where f(x) is some algebraic expression that depends on x. To find the derivative of this function, we use the rules of differentiation, which tell us how to find the rate of change of y with respect to x.

For example, suppose that the function is y = x^2 + 3x. Then, the derivative of this function is given by:

y' = 2x + 3

This means that the slope of the tangent line to the curve at any point is equal to the value of the derivative at that point. For instance, if x = 2, then the slope of the tangent is:

y'(2) = 2(2) + 3 = 7

the minimum score needed to be in the top 7% is 85.48, which can be rounded to 85.4. To determine the minimum score needed to be in the top 7%, we need to use the properties of the normal distribution and the corresponding z-score.

First, we need to find the z-score that corresponds to the top 7%. This can be done by using the standard normal distribution table or a calculator with a normal distribution function. The z-score that corresponds to the top 7% is approximately 1.48.

Next, we can use the formula for transforming a z-score to a raw score:

raw score = z-score * standard deviation + mean    

Substituting the values given in the problem, we get:

raw score = 1.48 * 6.1 + 76.4

raw score = 85.48

Therefore, the minimum score needed to be in the top 7% is 85.48, which can be rounded to 85.4.

In conclusion, the minimum score needed to be in the top 7% is 85.4. This calculation was performed by finding the z-score that corresponds to the top 7%, and then transforming the z-score to a raw score using the mean and standard deviation of the distribution.

Step-by-step explanation:

Equation of the Parabola

The general form of the equation of the parabola is:

\(f(x)=ax^2+bx+c\)

We can try to find the values of a,b, and c by using the three given points (1,0),(-3,0),(-9,28).

However, we'll use an easier method. There is another form of the parabola in case we know its roots, also called zeros or x-intercepts. If p and q are the roots of f, then f can be expressed as:

\(f(x)=a(x-p)(x-q)\)

We already know the values of p=1 and q=-3, thus replacing them into the equation, we have:

\(f(x)=a(x-1)(x+3)\)

We only need to find the value of a. We do that by using the point (-9,28):

\(28=a(-9-1)(-9+3)\)

Operating:

\(28=a(-10)(-6)=60a\)

Solving for a:

\(\displaystyle a=\frac{28}{60}=\frac{7}{15}\)

Thus, the equation of the parabola is:

\(\boxed{\displaystyle f(x)=\frac{7}{15}(x-1)(x+3)}\)

The slope of the line perpendicular to the line 2x - 12y = 120 will be -6.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following equation -

2x - 12y = - 120

Rearranging the equation, we get -

2x - 12y = 120

12y = 2x - 120

6y = x - 60

y = (1/6)x - 10

The slope of the line perpendicular to the line 2x - 12y = 120 will be -

m[2] = -1 / (1/6) = - 6

m[2] = - 6

Therefore, the slope of the line perpendicular to the line 2x - 12y = 120 will be -6.
