The composition of two isometries is an isometry.
Proof:
Let T1 and T2 be isometries. T1(A) = A' and T1(B) = B'. Therefore by isometry T1, AB = A'B'
T2(A) = A'' and T2(B) = B''. Therefore by isometry T2, AB = A''B''
T2 º T1 = T2(T1(A)) = T2(A') = A'''. T2 º T1 = T2(T1(A)) = T2(B') = B'''. Therefore under composition AB = A'''B''' and distance is preserved.
The inverse of an isometry is an isometry.
Proof:
Given T and isometry. This means T(A) = A' and T(B) = B' with AB = A'B'
The inverse of T, T⁻¹maps A' to A and B' to B, so A'B' maps to AB.
But A'B' = AB and so the inverse is an isometry

(12 × 4²) + 9/3²

Customers arrive at a checkout counter in a department store according to a Poisson distribution at an average of seven per hour. If it takes approximately ten minutes to serve each customer, find the mean use at least four digits after the decimal if rounding...)
and variance of the total service time for customers arriving during a 1-hour period. (Assume that a sufficient number of servers are available so that no customer must wait for service.) (use at least four digits after the decimal if rounding...) What is the probability that the total service time will exceed 2.5 hours? (use at least four digits after the decimal if rounding...)
The answer of this question is found to be 0.0012.
The mean total service time is 10 minutes times lambda (the average number to turn up during the hour)
Lambda is 7, since the average rate is 7 per hour and your time window is 1 hour.
mean service time = 7 × 10 = 70 minutes.
For a poisson process, lambda is both the mean and variance of the arrivals.
So the variance = 10² × lambda = 700, since we want the variance of the service time, rather than the variance of the arrival rate.
This is because:
σ(aX) = a × σ(X).
and σ = sqrt(variance)
σ(service time) = 10 σ(arrival time)
variance(service time) = (10 × σ(arrival time))²
variance(service time) = 100 × variance(arrival time) = 100 × lambda = 100 × 7
mean(servicetime) = 70
variance(servicetime) = 700
2.5 hour = 150 min
Z = [tex]\frac{(S - 70)}{\sqrt{700} }[/tex] follow N(0,1)
P(S > 150) = P( [tex]\frac{(S - 70)}{\sqrt{700} }[/tex]> [tex]\frac{(150 - 70)}{\sqrt{700} }[/tex])

Suppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards without replacement from a standard deck. If both cards are diamonds, your friend will pay you $615. Otherwise, you have to pay your friend $37.
Step 2 of 2 :
If this same bet is made 621 times, how much would you expect to win or lose? Round your answer to two decimal places. Losses must be expressed as negative values.
If this same bet is made 621 times,then we expect to lose of $4514670
Probability
A probability is a number that reflects the chance or likelihood that a particular event will occur. Probabilities can be expressed as proportions that range from 0 to 1, and they can also be expressed as percentages ranging from 0% to 100%.
The bet is done 621 times then expected value is that we may have a loss of $4514670.if the bet is that is heart comes we will get $615 and lose $37 if not comes.
$615 if hearts come and lose $37 when not comes and bet is made 621 times. Calculate the expected win after 621 times.
There are 578 hearts in the standard deck of cards.
Probability is the chance of happening an event among all the events possible. The formula of calculating probability is as under:
Probability= number of items/ total number of items.
When two cards are chosen at random without replacement then the probability of getting two hearts is 578/52*577/51
=333,506/2652
=125.75
When two cards are chosen at random without replacement then the probability of not getting two hearts is 1-125.75
=124.75
When bet is made only 1 time expected value will be 125.75*615-124.75*37
=77,336.25 - 4,615.75
=-72720.5 means we are expecting to lose $2.05.
When bet is made 762 times then the expected value will be -72720*621= 4514670.

Question 7
A light bulb used to have an averaged life time of 1000 hours. Now the
factory developed a novel technique hoping to extend its life time. We
randomly pick up 10 light bulbs produced by the new technique and the
measured life time mean value is 1077 hours with the standard deviation of
51.97 hours. If we do the t-test at the significance level of 2.5%, did the new
technology work?
(6 marks)
We can conclude that the new technique has extended the life of light bulbs. Yes it has worked
What is the t-test?Generally, To calculate the t-statistic, you would use the following formula:
t = (sample mean - hypothesized mean) / (standard deviation / √n)
Where "sample mean" is the mean life of the 10 light bulbs, "hypothesized mean" is the average life of the light bulbs before the new technique (1000 hours), "standard deviation" is the standard deviation of the sample (51.97 hours), and "n" is the number of light bulbs in the sample (10).
Plugging in the values, we get:
t = (1077 - 1000) / (51.97 / √10)
t= 77 / 5.197
t= 14.8
Now that you have calculated the t-statistic, you need to determine the critical value of t at a significance level of 2.5%.
Where
df=10-1
df=9
At a significance level of 2.5% and 9 degrees of freedom, the critical value of t is 2.262.
Since the t-statistic calculated for the sample (14.8) is greater than the critical value (2.262), you can reject the null hypothesis that the new technique did not extend the life of the light bulbs.

Part 1: The point of maxima is 21.212
Part 2: x = 21.212 is approximately equal to the year 2022
Part 3: The percentage at that time is 16.37%
Part 4: The rate of change of the percentage at that time is 0.294
Part 1:
p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236
where x is the number of years since 2000, data from 0<=x<=50
Differentiating the function with respect to x and equating it to 0
p'(x) = -0.00066x^2 + 0.028x - 0.0033
We will find the critical points of p'(x)
p''(x) = dp'(x)/dx = -0.00132x + 0.028
Critical points of p'(x) lies at x where p''(x) = 0
Thus, -0.00132x + 0.028 = 0
x = 0.028/0.00132 = 21.212
Now, p'''(x) = -0.00132<0
x = 21.212 is a point of maxima of p'(x)
Therefore, the maximum possible values of x could lie at x = 21.212 as well as the extreme points of the domain p'(x), i.e. at x = 0 and 50
p'(0) = -0.00066(0)^2 + 0.028(0) - 0.0033 = -0.0033
p'(21.212) = -0.00066(21.212)^2 + 0.028(21.212) - 0.0033 = 0.2936
p'(50) = -0.00066(50)^2 + 0.028(50) - 0.0033 = -0.2533
Hence p'(x) attains maxima at x = 21.212
Therefore, p(x) increases most rapidly at x = 21.212
Part 2:
From the given condition in the question, x = 0 corresponds to the year 2000
Thus x = 21.212 is approximately equal to year 2022
Part 3:
The percentage at that time:
p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236
p(21.212) = -0.00022(21.212)^3 + 0.014(21.212)^2 - 0.0033(21.212) + 12.236
= 16.365
= 16.37%
Part 4:
Rate of change of the percentage at that time
p(x) = −0.00022x^3 + 0.014x^2 − 0.0033x + 12.236
p'(21.212) = -0.00066(21.212)^3 + 0.028(21.212) - 0.0033

As per the data mentioned in the question,
In the form of the exponential equation.
y = [tex]ab^x[/tex]
The initial value is a, b is the growing (or decay) factor, and (b - 1) × 100% is the growth (or decay) rate,
A further point is that the equation depicts growth if b > 1 and decay if b < 1.
Taking into consideration the aforementioned, we discover that for exponential function,
y = 96(1.03)
a. Since 1.03 > 1, this show the growth in relationship.
b. the value of b = 1.03, so the growth factor is 1.03
c. The rate of growth
= ( 1.03 -1 ) × 100%
= 0.03 × 100% = 3%
d. Since 'a' has a value of 96, the starting value is also 96.

How to graph:
y= 2x - 5
Answer:
see attached
Step-by-step explanation:
You want to graph y = 2x -5.
GraphOften, the easiest way to graph a linear equation in slope-intercept form is to graph the y-intercept point, then use the slope to identify one or more additional points on the line. The graph is the line through the plotted points.
Slope-intercept formThe slope-intercept form of the equation of a line is ...
y = mx +b
where m is the slope, and b is the y-intercept.
The y-intercept is the point on the y-axis where the line crosses it. The coordinates there are (0, b).
Here, we have y = 2x -5, so m=2 and b=-5. The y-intercept point is (0, -5).
The slope is the ratio of "rise" to "run" for the line. A slope of 2 means the line rises 2 units for each 1 unit it goes to the right. That means (0 +1, b+2) will be another point on the line: (1, -3).
8. Jim hopes a park will be built within 5 miles of his
house. If a park is built at the coordinates (3, 7),
does that meet Jim's criteria? Explain.
No, he wanted a park developed within 5 miles of his residence, yet this park is 8.30 miles away.
What is coordinate?The horizontal and vertical distances from the two reference axes are used to define the location of a point on a coordinate plane. The x-value and y-value are often denoted as (x,y). To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to determine the y-coordinate. The distance between two points is known as the x-coordinate, or abscissa, while the distance between two points is known as the y-coordinate, or ordinate.
Here,
let the house be (0,0).
coordinate of park=(3,7)
distance=√3²+7²
=√21+49

find the flux through the boundary of the rectangle for fluid flowing along the vector field .
For fluid moving in a vector field, the flux through the rectangle's perimeter is 750.52.
Flux = ∫ F. X ds
Flux = ∫∫ delta. F da (by divergence theorem)
delta. F = d/dx(x³+4) + d/dy(ycos(3x))
= 3x² + cos(3x)
So flux = ∫∫ 3x² + cos(3x) dy dx
= ∫ (3x² + cos(3x)) (y)⁶₀ dx

assume that a and b are positive integers. for each statement below, determine whether the statement is true or false, and indicate your answer in the appropriate box
Given Statement (a!)b = ab! is false becuase it is not appropriate to represent factorial like this.
What is Factorial?
In mathematics, the term "Factorial" refers to the sum of all positive integers that are less than or equal to a certain positive integer, which is followed by an exclamation point. Thus, factorial seven is denoted by the symbol 7!, which stands for 1*2*3*4*5*6*7. Factorial 0 is equivalent to 1 by definition.
(a!)*b = ab!
this depends on the value of a and b.
I'm not sure if the phrase "ab!" means to multiply a by b and then compute the factorial of the resulting product, as in (ab)!, or to compute the factorial of b first and then multiply this by a, as in a(b!). Either way, the assertion is false.
