Susan could save 10.4 minutes getting to class each morning if she were to ride the bike.
As per the data given:
The distance is given between the school and the apartment = 1.3 miles
Susan's walking speed = 3 miles/hr
Now we know that speed = distance ÷ time
Putting values in the above formulae, we get the time for walking situation
3 miles/hr = 1.3 ÷ time
Time = 1.3 ÷ 3 miles
Time = (13 ÷ 30 )hr
= (13 ÷ 30) × 60 minutes
= 13 × 2
= 26 minutes
The time taken when she is walking is 26 minutes.
Here we have to determine how many minutes could Susan save getting to class each morning if she were to ride the bike.
Now if she uses a bike, the speed is 5 miles/hr
Again applying same formulae speed = distance ÷ time
5 miles/hr= 1.3 ÷ time
Time= 1.3 ÷ 5 miles
= (13 ÷ 50)hr
= (13 ÷ 50) × 60 minutes
= 15.6 minutes
Time taken by bike is 15.6 minutes
Total time saved = time taken when walking - time taken using the bike
= 26 - 15.6
= 10.4 minutes
Hence, Susan could save 10.4 minutes if she uses a bike.

Assume that T is a linear transformation. Find the standard matrix of T. T: R2→R2 first reflects points through the line x2-x1 and then reflects points through the line x2-x1 A= (Type an integer or simplified fraction for each matrix element)
the standard matrix of T. T: R2→R2 is [ 0 1 ]
[ 1 0]
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)
Hence, (0,1) and (1,0) are the images of the standard basis vectors, These photos can now be expressed as columns in a matrix:
[0 1]
[1 0]
This is the standard matrix of T.

The triangle with sides 44, 73, and 86 is an obtuse triangle.
The Pythagorean Theorem states that the square of the length of the hypotenuse (the side opposite the right angle) in a right triangle is equal to the sum of the squares of the lengths of the other two sides, can be used to determine whether the triangle is right, acute, or obtuse.
In an acute triangle, the square of the hypotenuse length is less than the sum of the squares of the other two sides; in an obtuse triangle, the square of the hypotenuse length is greater than the sum of the squares of the other two sides.
Begin by calculating the square of each side:
[tex]44^2 = 1936[/tex]
[tex]73^2 = 5329[/tex]
[tex]86^2 = 7396[/tex]
Let us now see if the triangle fulfils the Pythagorean Theorem:
1936 + 5329 = 7265
We know the triangle is not obtuse because 7265 is less than 7396.
1936 + 7396 = 9332
We know the triangle is not acute because 9332 is greater than 5329.
5329 + 7396 = 12725
We know the triangle is obtuse because 12725 is greater than 7265 but less than 9332.
As a result, the triangle with sides 44, 73, and 86 is obtuse.

An airline has two flights traveling from CVG to ORD on a busy Friday evening. Flight A is scheduled to leave at 6:30 p.m. The airplane for flight A has a capacity of 96 passengers. The second flight, Flight B, leaves one hour later and has a capacity of only 68 passengers. Based on historical data, the airline knows that the probability that a passenger on Flight A will be a no-show is 0.03 and the probability that a passenger will be a no-show on Flight B is 0.02. For this exercise, we will assume that passenger no-shows are independent events. Round all answers to four decimal places. 6. If the airline chooses not to oversell flight A and sells exactly 96 tickets, what is the probability that it will have a full flight (i.e. all 96 passengers show up)? 7. If the airline oversells flight A with 99 tickets sold, what is the probability that all passengers that show up will have a seat on the flight (i.e. 3 or more no-shows)? 8. If the airline oversells flight B with 70 tickets sold, what is the probability that the flight will have exactly 68 customers show up? 9. If the airline oversells flight B with 72 tickets, what is the probability that all passengers that show up will have a seat on the flight?
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.

(b) distance covered in additional z seconds is [tex]distance= 4zmeter[/tex]
(c)[tex]d(x)=30m+4(x-7s)[/tex]
What is velocity?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:

The answer is (a) -25. The covariance is negative, indicating that the December snowfall and temperature in Syracuse NY have an inverse relationship. 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
As a result, the answer is (a) -25. The covariance is negative, indicating that the December snowfall and temperature in Syracuse NY have an inverse relationship.

(a) The research hypothesis being tested in this study is a causal hypothesis. The company president believes that the type of music listened to can predict production line output.
(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.
Therefore, it is difficult to determine if any differences in production line output are actually due to the type of music listened to. A true experiment with random assignment of workers to the two music conditions would provide a better test of the research hypothesis.

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) .

AB dotted line segment correctly represents the perpendicular bisector of line segment XY
What is Straight Line?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
