The systematic succession of phases that a product goes through as it develops from start to finish is known as the agile software development life cycle. Concept, conception, iteration, release, maintenance, and retirement are its six phases.
The project management approach a team decides on will have a small impact on the Agile life cycle. For instance, Scrum teams work in sprints, which are brief timeframes akin to iterations. They also have responsibilities that are precisely defined, like Scrum master. Kanban teams, on the other hand, operate more continuously and don't have set roles. Another illustration is Extreme Programming, where teams frequently work in shorter iterations and give engineering practices more attention.

using the digits $1$, $2$, $3$, $4$, $5$, how many even three-digit numbers less than $500$ can be formed if each digit can be used more than once?
The number of three-digit numbers less than $500 that cab be formed is 90.
How to form three digit numbers numbers from a set?The formation of the numbers involves the permutation of the first three even digits. Also, permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear.
The sequence include the following: $1$, $2$, $3$, $4$, $5$,
The number must be less than $500$.
In order to find the number of even digits numbers to be fixed, we select the even numbers.
So, the number of possible arrangements = [tex]6_{P_{2} }[/tex]
[tex]\frac{6!}{(6-2)!}[/tex]
=[tex]\frac{6*5*4*3*2*1}{4*3*2*1}[/tex]

The probability that a college student will get to work in 30 mins or less is 0.4 or 40%.
What does uniformly distributed probability mean?
Uniform distribution refers to a type of probability distribution in which all outcomes are equally likely to occur.
According to the given question:
Since the time is uniformly distributed, every possible travel time has the same likelihood of occurring.
Lower boundary (L) = 20 minutes
Upper boundary (U) = 45 minutes
The probability that a student finishes her trip in 30 minutes or less is:
P (t ≤ 30) = (30 - L)/(U - L)
= (30 - 20)/(45 - 20)
= 10/25

Can you use a right triangle to represent the distance between any two points on the coordinate plane?.
Yes. A leg of a right triangle can indicate the distance that separates two vertical or horizontal points, and the hypotenuse can represent the distance between two non-vertical or non-horizontal points.
We can use this theorem to calculate the distances between two locations on a coordinate grid. Consider the following example using the points:
( 3, 4 ) and ( − 2, 1 )
We can see how to make a right triangle with the hypotenuse as that of the line connecting these two spots. A right angle is formed at the coordinates ( 3, 1), where the vertical line from ( 3, 4 ) and the horizontal line from ( 2, 1 ) intersect.

Which line is the graph of y = 2x - 1?
line a
line d

line b
Answer:
Line A
Step-by-step explanation:
The slope of 2x is a positive slope so it can't be line d(which is negative) or line c(which is horizontal).
That leaves us with lines a and b. 2x is a steep slope and line a has a steep slope while line b has a shallow slope so it is line a.

How do you calculate obtuse value?.
Calculating the obtuse angle or value of a triangle.
Finding obtuse angle value:
steps:
1) Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together.
For example, if the lengths of the sides measure 4 and 2, then squaring them would result in 16 and 4. Adding the squares together results in 20.
2) Square the length of the side opposite the obtuse angle. For the example, if the length is 5, then squaring it results in 25.
3) Subtract the combined squares of the adjacent sides by the square of the side opposite the obtuse angle. For the example, 25 subtracted from 20 equals -5.
4) Multiply the lengths of the adjacent sides together, and then multiply that product by 2. For the example, 4 multiplied by 2 equals 8, and 8 multiplied by 2 equals 16.
5) Divide the difference of the sides squared by the product of the adjacent sides multiplied together then doubled. For the example, divide -5 by 16, which results in -0.3125.
The obtuse angle value is obtained by inverse of cos:
cos^-1(-0.3125)

Define Rate of change
Rate of change (ROC) refers to how quickly something changes over time.The acceleration or deceleration of changes (i.e., the rate) and not the magnitude of individual changes themselves.Formula is, Rate of change = ( f(b) - f(a) ) / (b - a)Given function is,
f(x) = 5(2) ^ x
where, x = 1 to x = 5
We know, the formula of rate of change is
Rate of change = ( f(b) - f(a) ) / (b - a)
for x = 5, for that put value of x in given function
f(x) = 5(2) ^ x
f(5) = 5(2) ^ 5
f(5) = 160
for x = 1, for that put value of x in given function
f(x) = 5(2) ^ x
f(1) = 5(2) ^ 1
f(1) = 10
Now, plug in the values in rate of change formula
Rate of change = ( f(5) - f(1) ) / (5 - 1)

What is the monthly finance charge if the average daily balance is $30, the daily periodic rate is 0.07%, and the number of days in the cycle is 30? a. 21¢ b. 63¢ c. 90¢
The monthly finance charge is 63 cents.
Here we have to find the monthly finance charge.
The given data:
Average daily balance = $30
The daily periodic rate = 0.07%
The number of days in a cycle is 30.
The formula to find the finance charge:
Finance charge = APR balance × number of days in billing cycle / 365
As it is given a daily periodic rate this means that:
APR / 365 = 0.07%
= 0.0007
Hence, putting the value in the formula we have:
Finance charge = 0.0007 × 30 × 30
= 0.63
As we know that $1 = 100 cents
So finance charge = 0.63 × 100
= 63 cents
Therefore the finance charge is 63 cents.
