AB dotted line segment correctly represents the perpendicular bisector of line segment XY

A line is an infinitely long object with no width, depth, or curvature.

A perpendicular bisector can be defined as a line segment which bisects another line segment at 90 degrees.

In other words, a perpendicular bisector intersects another line segment at 90° and divides it into two equal parts.

In the given figure the XY is a straight line.

The perpendicular bisector to this line is AB.

Hence, AB dotted line segment correctly represents the perpendicular bisector of line segment XY

6. The probability that Flight A will have a full flight is 0.4163.

7. The probability that all passengers who show up will have a seat on the flight is 0.5731.

8. The probability that Flight B will have exactly 68 customers show up is 0.0904.

9. The probability that all passengers that show up will have a seat on the flight is 0.9707.

6. If the airline chooses not to oversell flight A and sells exactly 96 tickets, the probability that it will have a full flight can be calculated using the binomial distribution. Let X be the number of passengers who show up for the flight.

Then, X follows a binomial distribution with n = 96 and p = 0.97 (since the probability that a passenger shows up is 1 - 0.03 = 0.97). Thus, the probability that all 96 passengers show up is:

P(X = 96) = (96 choose 96) × [tex]0.97^{96}[/tex] × [tex]0.03^0[/tex] = 0.4163

So, the probability that Flight A will have a full flight is 0.4163.

7. If the airline oversells Flight A with 99 tickets sold, the probability that all passengers who show up will have a seat on the flight (i.e. 3 or more no-shows) can be calculated using the binomial distribution again. Let Y be the number of no-shows for the flight. Then, Y follows a binomial distribution with n = 99 and p = 0.03. We want to find the probability that Y is greater than or equal to 3 (i.e. there are 3 or more no-shows), which can be calculated as:

P(Y >= 3) = 1 - P(Y <= 2) = 1 - ((99 choose 0) × [tex]0.03^0[/tex] × [tex]0.97^{99}[/tex] + (99 choose 1) × [tex]0.03^1[/tex] × [tex]0.97^{98}[/tex] + (99 choose 2) × [tex]0.03^2[/tex] × [tex]0.97^{97}[/tex]) = 0.5731

So, the probability that all passengers who show up will have a seat on the flight is 0.5731.

8. If the airline oversells Flight B with 70 tickets sold, the probability that the flight will have exactly 68 customers show up can be calculated using the binomial distribution with n = 70 and p = 0.98 (since the probability that a customer shows up is 1 - 0.02 = 0.98). Let Z be the number of customers who show up for the flight. Then, the probability that exactly 68 customers show up is:

P(Z = 68) = (70 choose 68) × [tex]0.98^{68}[/tex] × 0.02² = 0.0904

So, the probability that Flight B will have exactly 68 customers show up is 0.0904.

9. If the airline oversells Flight B with 72 tickets sold, the probability that all passengers who show up will have a seat on the flight can be calculated using the binomial distribution again. Let W be the number of no-shows for the flight. Then, W follows a binomial distribution with n = 72 and p = 0.02. We want to find the probability that W is less than or equal to 3, which can be calculated as:

P(W <= 3) = (72 choose 0) × [tex]0.02^0[/tex] × [tex]0.98^{72}[/tex] + (72 choose 1) × [tex]0.02^1[/tex] × [tex]0.98^{71}[/tex] + (72 choose 2) × [tex]0.02^2[/tex] × [tex]0.98^{70}[/tex] + (72 choose 3) × [tex]0.02^3[/tex] × [tex]0.98^{69}[/tex] = 0.9707.

Step-by-step explanation:

Answer:

Step-by-step explanation:

To differentiate the function y = x^4 - x, we will use the power rule of differentiation. The power rule states that if f(x) = x^n, then the derivative of f(x) is f'(x) = nx^(n-1).

So, for y = x^4 - x, we can find the derivative as follows:

y' = 4x^3 - 1

So, the derivative of the function y = x^4 - x is y' = 4x^3 - 1.

No, it is not possible to have a function f defined on [2,4] that is continuous and has an unbounded range. This is because of the Extreme Value Theorem, which states that a continuous function on a closed interval must have a maximum and minimum value within that interval. If the range of f is unbounded, then there is no maximum or minimum value, which contradicts the Extreme Value Theorem. Therefore, it is not possible to have such a function.

If we modify the condition to allow for an unbounded range in only one direction (either unbounded from above or unbounded from below), then it is possible to have a function that is continuous on [2,4] with an unbounded range.

For example, consider the function f(x) = 1/(x-4) defined on the interval [2,4]. This function is continuous on [2,4] and has an unbounded range in the negative direction, as f(x) approaches negative infinity as x approaches 4 from the left.

Another example is the function g(x) = x^2 defined on the interval [2,4]. This function is continuous on [2,4] and has an unbounded range in the positive direction, as g(x) approaches infinity as x approaches 4 from the right.

So, it is possible to have a continuous function on [2,4] with an unbounded range in one direction, but not in both directions simultaneously.

The derivation of the critical radius(r*) as  and critical saturation(S*) as  is explained below .

To derive the critical saturation ratio (S*) and critical radius (r*),

We  use calculus to find the maximum value of the saturation ratio for a given radius on the Kohler curve.

First, let us consider the equation for the saturation ratio, S, as a function of radius, r:

that is : S = 1 + ar²/3b  ;

where a and b are constants.

Next, we find the derivative of S with respect to r:

On differentiating Curve "S" with respect to "r" ;

⇒ dS/dr = 2ar/3b  ;

Equating the derivative = 0 , we can find the critical points:

⇒ dS/dr = 0 = 2ar/3b  ;

On Solving for r, we have ;

⇒ r* = √(3b/a)

Next , to find the critical saturation ratio(S*) , we substitute r* back into the original equation for S:

⇒ S* = 1 + ar²/3b = 1 + a×(3b/a)/3b = 1 + √(4a³/27b)

Therefore , the critical saturation ratio and critical radius are written as r* = √(3b/a)  and  S* = 1 + √(4a³/27b)  .

Answer: The value of the limit of the function may not be equal to the value of the function evaluated at a particular x-value. In other words, just because a function takes on a certain value at a particular x-value doesn't mean that the limit of the function at that x-value is equal to that value. To determine the limit of the function, you may need to use different methods such as L'Hopital's Rule or other limit laws. Additionally, it's important to keep in mind that the limit of the function may not exist, in which case it wouldn't be equal to any specific value.

(a) The max speed of Gregory is, [tex]v_{max} =\frac{32}{4} =8s[/tex]

(b) distance covered in additional z seconds is [tex]distance= 4zmeter[/tex]

(c)[tex]d(x)=30m+4(x-7s)[/tex]

Velocity is defined as the rate of change position of the object with respect to the time and frame of reference.

Gregory runs a 100-meter race. 5 seconds after the race started he is 30 meters from the starting line and reaches his max speed.

(a)The max speed covered by Gregory is ,

For constant speed, we know,

[tex]v=\frac{distance}{time taken}[/tex]

distance= 62m-30m=32m.

And the time take to reach 62m will be

time =9s-5s=4s

So, Gregory's max speed is,

[tex]v_{max} =\frac{32}{4} =8s[/tex]

(b) Suppose Gregory runs for an additional z seconds after reaching his max speed,

As the velocity of Gregory's is [tex]v_{max}[/tex], the distance covered by him is,

[tex]distance=v_{max}*zs[/tex]

[tex]distance= 4zmeter[/tex]

(c) At time 5+ z seconds the distance will be the30

meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:

[tex]distance=v_{max}*z+30\\distance=4\frac{m}{s} *z s[/tex]

At time x ( x greater or equal to 5 seconds) the distance will be the 30 meters he covers in the first part of the race plus the distance he traveled at constant speed. this is:

[tex]d(x)=30m+v_{max}*(x-5s)\\ d(x)=30m+4(x-7s)[/tex]

The function's two zeros are: x = -1 and x = 6.

In mathematics, a function is a set of ordered pairs (input, output), where each input is associated with exactly one output. The input is commonly referred to as the independent variable, and the output is referred to as the dependent variable. A function can be represented algebraically, graphically, or verbally. Algebraically, a function is often represented by an equation that defines the relationship between the independent variable and the dependent variable. For example, the equation y = 2x + 1 defines a linear function, where x is the independent variable and y is the dependent variable.

Here,

The zeros of a function are the values of the independent variable for which the function equals zero. To determine all zeros for the function f(x) = (2x + 2)(x - 6), we need to find the solutions to the equation f(x) = 0.

To do this, we can set the two factors equal to zero and solve for x:

2x + 2 = 0

x = -1

x - 6 = 0

x = 6

These are the two zeros of the function: x = -1 and x = 6.

(b) The type of design being used in this study is a non-experiment. The researcher is not manipulating the type of music listened to; instead, the plant is naturally exposed to either country or classical music.

(c) The design being used in this study is within-subjects design, as the same group of individuals is exposed to both types of music. It is also a repeated measures design, as the same individuals are measured twice (once under country music and once under classical music).

(d) No, the design used in this study cannot provide an appropriate test of the research hypothesis. Since the researcher is not manipulating the type of music listened to, it is possible that other variables could be affecting the production line output, such as different environmental conditions on each week, or different levels of motivation.

Snowfall, in particular, tends to decrease as temperatures rise. Covariance units are the product of the units of the two variables, which in this case are in2 and (degrees F)2, so covariance units are degree inches.

We are given the following details:

Correlation coefficient between December snowfall and temperature in Syracuse, New York: -0.5

December snowfall variation (S): 100 in2

Temperature variation in December (T): 25 (degrees F)2

We are asked to calculate the correlation between December snowfall and temperature in degrees inches.

Cov(S,T) can be calculated using the covariance formula:

Corr(S,T) = Cov(S,T) * sqrt(Var(S)) * sqrt(Var(T))

Plugging in the values from the problem yields:

Cov(S,T) = (-0.5) * sqrt(100 in2) * sqrt(25 (degrees F)2) = (-0.5) * 10 in * 5 degrees F = -25 degree inches

We must locate the pictures of the standard basis vectors of R2 under T and translate those images into columns of a 2x2 matrix in order to get the standard matrix of T.

Let's start by thinking about the reflection along the line x2 - x1. The point (x1, x2) is mapped to the point via this reflection (x2, x1).

We apply T to the first standard basis vector, e1 = (1,0), to determine its image:

T(e1) = (0,1) (0,1)

We also use T: to determine the image of the second standard basis vector, e2 = (0,1).

T(e2) = (1,0) (1,0)
