Answers
Together, Bob and John will need 10 hours to finish the computer program with the given rate of working.
How to solve rate of change based problems?We divide the change in y (output) by the change in x to determine the average rate of change (input).
How is work completed measured?The amount of work finished in a single day if a task takes x days to complete is equal to 1/x.
It is given that In 30 hours, Bob can write a computer program. John can write a computer program in half the time that Bob takes.
Bob's rate = B
John 's rate = J
B × 30 = J × 15
Rate of Bob = 1/30 h
Rate of John = 1/15 h
Total time(1/30 + 1/15) = Computer Program
(1/30 + 1/15) = Computer Program/Total time
0.099 = Computer Program/Total time
So, total time = 1/0.099 = 10 hours/computer program
Therefore, Bob and John will finish the computer program in a total of 10 hours.

Step-by-step explanation:
Find and classify the global extrema of the following function:
f(x) = -x^3 + 5 x^2 + x
Find the critical points of f(x):
Compute the critical points of -x^3 + 5 x^2 + x
To find all critical points, first compute f'(x):
d/(dx) (-x^3 + 5 x^2 + x) = -3 x^2 + 10 x + 1:
f'(x) = -3 x^2 + 10 x + 1
Solving -3 x^2 + 10 x + 1 = 0 yields x = 1/3 (5 - 2 sqrt(7)) or x = 1/3 (5 + 2 sqrt(7)):
x = 1/3 (5 - 2 sqrt(7)), x = 1/3 (5 + 2 sqrt(7))
f'(x) exists everywhere:
-3 x^2 + 10 x + 1 exists everywhere
The critical points of -x^3 + 5 x^2 + x occur at x = 1/3 (5 - 2 sqrt(7)) and x = 1/3 (5 + 2 sqrt(7)):
x = 1/3 (5 - 2 sqrt(7)), x = 1/3 (5 + 2 sqrt(7))
The domain of -x^3 + 5 x^2 + x is R:
The endpoints of R are x = -∞ and ∞
Evaluate -x^3 + 5 x^2 + x at x = -∞, 1/3 (5 - 2 sqrt(7)), 1/3 (5 + 2 sqrt(7)) and ∞:
The open endpoints of the domain are marked in gray
x | f(x)
-∞ | ∞
1/3 (5 - 2 sqrt(7)) | -0.0490425
1/3 (5 + 2 sqrt(7)) | 21.9009
∞ | -∞
The largest value corresponds to a global maximum, and the smallest value corresponds to a global minimum:
The open endpoints of the domain are marked in gray
x | f(x) | extrema type
-∞ | ∞ | global max
1/3 (5 - 2 sqrt(7)) | -0.0490425 | neither
1/3 (5 + 2 sqrt(7)) | 21.9009 | neither
∞ | -∞ | global min
Remove the points x = -∞ and ∞ from the table
These cannot be global extrema, as the value of f(x) here is never achieved:
x | f(x) | extrema type
1/3 (5 - 2 sqrt(7)) | -0.0490425 | neither
1/3 (5 + 2 sqrt(7)) | 21.9009 | neither

a university found that 14% of its students withdraw without completing the introductory statistics course. assume that 20 students registered for the course. if required, round your answer to four decimal places. (a) compute the probability that 2 or fewer will withdraw
Answers
The Probability that 2 or fewer will withdraw without completing the introductory statistics course is 0.4547 .
The Binomial Distribution formula is
P(X=x) = C(n,x)*pˣ*qⁿ⁻ˣ
where ,
n is the number of trials
x is the number of times success occurs
p is the probability of success
q is the probability of failure .
In the given question ;
it is given that
students that are registered for the course = 20
so , n=20
Let x denote the number of students that withdraw without completing the course .
given that 14 % students withdraw without completing the course ,
hence p = 14% = 0.14
So , q= 1-p = 1-0.14 = 0.86
the probability that 2 or fewer will withdraw from the course is denoted by P(X ≤ 2) and is calculated using
the formula , P(X≤2)=P(X=0)+P(X=1)+P(X=2) ...(i)
using Binomial Probability we get
P(X=x) = C(n,x)*pˣ*qⁿ⁻ˣ
P(X=0) = C(20,0)*(0.14)⁰*(0.86)²⁰⁻⁰
= C(20,0)*(0.14)⁰*(0.86)²⁰
= 1*1*(0.0489)
= 0.0489
So , P(X=0)=0.0489 ...(ii)
P(X=1) = C(20,1)*(0.14)¹*(0.86)¹⁹
= 20*0.14*0.0569
= 0.1593
So , P(X=1)=0.1593 ...(iii)
P(X=2) = C(20,2)*(0.14)²*(0.86)¹⁸
= 190*0.0196*0.0662
= 0.2465
So , P(X=2)=0.2465 ...(iv)
Substituting the values of (ii) , (iii) and (iv) in (i) , we get
P(X≤2)=P(X=0)+P(X=1)+P(X=2)
P(X ≤ 2) = 0.0489 + 0.1593 + 0.2465
= 0.4547
Therefore , the Probability that 2 or fewer will withdraw without completing the introductory statistics course is 0.4547 .

If there are 200 people in a cinema and the probability of choosing a person eating popcorn is 0.25, how many people in the cinema are eating popcorn?
Answers
800 people in the cinema are eating popcorn by probability.
What does math probability mean?
Probability is the study of possible outcomes of events, along with their comparative probabilities and distributions.Probability is the measure of how probable something is to happen. As an illustration, since there is only one way to get a head and a total of two potential outcomes, the probability of flipping a coin and getting heads is one in two. a tail or a head. We write P(heads) = 12 here.Total people in cinema = 200
probability of choosing a person eating popcorn is = 0.25
people in the cinema are eating popcorn = 200/0.25
people in the cinema are eating popcorn = 800

Are the ratios 5:3 and 6:4 equivalent?
Answers
Answer:
I believe so but I'm nor 100% sure
The ratios 5:3 and 6:4 are not equivalent.
What are ratios?A ratio in mathematics illustrates how many times one number contains another. For example, if a dish of fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Equivalent ratios are those that are the same when compared. Two or more ratios can be compared to determine whether they are equal. For example, the ratios 1:2 and 2:4 are equal.
The given two ratios are 5:3 and 6:4. We can write them as 5/3 and 6/4
Let us apply subtraction, if we get 0 then these are equivalent.
6/4-5/3
The LCM of 4 and 3 is 12
=(18-20)/12
The value of 18-20 is -2
=-2/12
We have to divide 2 by 12 we get -1/6.
=-1/6 not equal to 0
Therefore, it can be concluded that the ratios 5:3 and 6:4 are not equivalent.

Triangle A'B'C' is the image of ABC under a dilation with a scale factor of 2.
What is the length of segment
——
A’B’?
Answers
After dilation, the length of line segment A'B' is 6 units.
What is dilation?Resizing an object uses a transformation called dilation. Dilation is used to enlarge or contract objects. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. A dilation in mathematics is a function f from a metric space M into itself that, for all points x, y in M, satisfies the identity d=rd, where d is the distance between x and y and r is some positive real number. Such a dilation is a similarity to the space in Euclidean space.So, the length of line segment AB:
We would multiply a figure by 2 when dilating it by its length.The length of AB is 3 units.After dilation:
3 × 2 = 6 unitsTherefore, after dilation, the length of line segment A'B' is 6 units.

A = {Prime numbers between 10 and 16} B = {Multiples of 3 between 10 and 16}
(a) List the members of AUB.
(b) What is AB?
(c) Is it true that 11 € B?
Answers
Part (a)
A = {prime numbers between 10 and 16}
A = {11, 13}
B = {multiples of 3 between 10 and 16}
B = {12, 15}
A U B = union of set A with set B
A U B = {set of stuff from A or B or both}
A U B = {11, 12, 13, 15}
=================================================
Part (b)
I'm assuming that you meant to write [tex]A \cap B[/tex]
If so, then this is the set of values inside set A and set B at the same time.
Since there is no common overlap between the sets A and B, we say that the answer is the empty set. We write the empty set as a pair of curly braces with nothing inside. Not even zero is a member of the empty set.
[tex]A \cap B = \{ \ \}[/tex]
we could also write the empty set using the symbol [tex]\varnothing[/tex]
So,
[tex]A \cap B = \varnothing[/tex]
=================================================
Part (c)
Answer: FalseReason:
The weird looking E symbol in this context means "is inside" or "is part of"
In other words, a statement like [tex]11 \in B[/tex] translates to "11 is part of set B", which is a false statement. Recall that B = {12, 15}
If we said [tex]11 \in A[/tex], then it would be true since A = {11, 13} which shows 11 as one of the values of set A.
two hundred and fifty six x^4 minus one thousand two hundred and ninety six y^4
Answers
The expression two hundred and fifty six x^4 minus one thousand two hundred and ninety six y⁴ will be 16(4²x⁴ - 9²y⁴)
How to explain the expression?It should be noted that expressions simply means one or more number or variables that are used to represent a data or a particular information.
It should be noted that two hundred and fifty six x⁴ minus one thousand two hundred and ninety six y^4 will be expressed as:
256x⁴ - 1096y⁴
