64x^12+27y^3
Answer:
(4x^4 + 3y) * (16x^8 - 12x^4 y + 9y^2)
Step-by-step explanation:
rewrite 64x^12 as (4x^4)^3
(4x^4)^3 + 27y^3
rewrite 27y^3 as (3y)^3
a^3+b^3=(a+b)(a^2 - ab + b^2)
(4x^4 + 3y) ((4x^4)^2 - (4x^4 * (3y) + (3y)^2)
[tex]\\ \rm\Rrightarrow 64x^{12}+27y^3[/tex]
[tex]\\ \rm\Rrightarrow 4^3x^3x^6x^3+3^3y^3[/tex]
[tex]\\ \rm\Rrightarrow (4xxxx)^3+(3y)^3[/tex]
[tex]\\ \rm\Rrightarrow (4x^3)^3+(3y)^3[/tex]
a^3+b^3=(a+b)(a^2+ab+b^2)[tex]\\ \rm\Rrightarrow (4x^3+3y)(16x^6+12x^3y+9y^2)[/tex]

How can i solve for x
Answer:
Step-by-step explanation:
So we know the square is 90 degrees because it is a right angle, We need to find x = The shape of x is a acute angle which is smaller than a right and obtuse = Obtuse angles are larger than right angles. So look through the answer and find one that is smaller number than 90 degrees.

-80% + 54/50 - 0.25
Answer: 0.03
Step-by-step explanation:
Suppose that you have read the following excerpt in a journal/research article:
We have sufficient evidence (at alpha equals 5%) to conclude that employee sales (in number of units sold) differ by traning program format (no training session, one training session, two training sessions).
Which of the following statements must be true based on this excerpt?
A. Employees attending two training sessions had the highest average sale
B. Employees with more training will always sell more units
C. The author's p-value was less than 5%
D. The author used a 10% Type-I Error probability
E. Our factor variable has only two levels since "No Training" cannot be a factor level
Consider the following hypothetical Multiple Comparisons of Means results for a study concerning differences in employee sales (in number of units sold) by training program format. Suppose that our sample consisted of sales employees and that we had sufficient evidence to reject the ANOVA null hypothesis.
Training Program Format Sample Average Sales (in Units Sold) Homogeneous Groups
No Training Session 300.05 A
One Training Session 345.68 B
Two Training Sessions 350.33 B
Which of the following statements is true based on the table above?
A. We do not need to consider the cost of the training sessions when choosing the best training program format
B. Training Program Format is our response/dependent variable
C. We expect an increase in sales when we implement one or two training sessions, but we do not expect a training program with two sessions to lead to significantly more sales than a program with only a single training session
D. Having a training program with three sessions will result in an increase in sales compared to having a training program with two sessions
Having a training program with two sessions yields significantly more sales than a training program with only one session

Problem 2:
Priya is walking down a long hallway. She walks halfway and stops. Then, she walks half of the remaining distance, and
stops again. She continues to stop every time she goes half of the remaining distance.
1. What fraction of the length of the hallway will Priya have covered after she starts and stops two times?
2. What fraction of the length of the hallway will Priya have covered after she starts and stops four times?
3. Will Priya ever reach the end of the hallway, repeatedly starting and stopping at half the remaining distance? Explain
your thinking.
Answer:
The answers to the questions about problem 2 are:
The fraction of the length after Priya stops two times is 3/4.The fraction of the length after Priya stops four times is 15/16.Priya will never reach the end of the hallway.Step-by-step explanation:
The explanation about each answer is below:
1. In the first stop, Priya has walked half of the total length, and there would still be half the hallway, however, when she stops the second time, she has walked the half of the half, I mean:
[tex]\frac{1}{2}/2=\frac{1}{4}[/tex]
If you add the two values you obtain the total distance traveled by Priya:
[tex]\frac{1}{2}+\frac{1}{4}= \frac{3}{4}[/tex]
And the distance traveled in two stops is 3/4 of the total length of the hallway.
2. With four stops the system is the same, we know with two stops Priya travels 3/4 of the hallway, now with the third stop, she will travel half of the remaining distance:
[tex]\frac{1}{4}/2=\frac{1}{8}[/tex]
And in the fourth stop she will travel half of the remaining, I mean:
[tex]\frac{1}{8}/2=\frac{1}{16}[/tex]
Now, we add all the values of the distances obtained:
[tex]\frac{3}{4}+\frac{1}{8}+\frac{1}{16}= \frac{15}{16}[/tex]
So, the distance traveled by Priya in the fourth stop is 15/16 of the total length of the hallway.
3. How we know, the numbers are infinite, in the same forms the distances, by this reason, how the problem says that Priya walks just half of the distance, she will never reach the end because despite she has very near of the end, she will continue walking just half and ever smaller distances.

Step-by-step explanation:
Can someone help me please, I would appreciate it
Answer:
1.
-2x - 9y = -3
-7x - 9y= -33
Set equal to y.
-2x - 9y = -3
-9y = 2x - 3
y = -2/9x + 3/9
y = -2/9x + 1/3
-7x - 9y= -33
-9y = 7x - 33
y = -7/9x + 33/9
y = -7/9x + 11/3
Set equal to each other
-2/9x + 1/3 = -7/9x + 11/3
Combine like terms.
5/9x = 10/3
Multiply by 9/5
x = 6
Plug x in.
y = -7/9(6) + 11/3
y = -42/9 + 11/3
y = -42/9 + 33/9
y = -9/9
y = -1
(6, -1)
2.
-3x - 7y = 18
9x + 2y = 3
Set equal to y.
-3x - 7y = 18
-7y = 3x + 18
y = -3/7x - 18/7
9x + 2y = 3
2y = -9x + 3
y = -9/2x + 3/2
Set equal to each other.
-3/7x - 18/7 = -9/2x + 3/2
57/14x = 57/14
Multiply 14/57.
x = 1
Plug x in.
-3(1) - 7y = 18
-3 - 7y = 18
-7y = 21
y = -3

A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a chance of getting the project. However, the agency to which the bid was submitted subsequently requested additional information on the bid. Past experience indicates that for of the successful bids and of the unsuccessful bids the agency requested additional information.
1. What is the prior probability of the bid being successful (that is, prior to the request for additional information)?2. What is the conditional probability of a request for additional information given that the bid will ultimately be successful?3. Compute the posterior probability that the bid will be successful given a request for additional information (to 2 decimals).
Complete question is;
A consulting firm submitted a bid for a large research project. The firm's management initially felt they had a 50-50 chance of getting the project. However, the agency to which the bid was submitted subsequently requested additional information on the bid. Past experience indicates that for 74% of the successful bids and 39% of the unsuccessful bids the agency requested additional information.
1. What is the prior probability of the bid being successful (that is, prior to the request for additional information)?
2. What is the conditional probability of a request for additional information given that the bid will ultimately be successful?
3. Compute the posterior probability that the bid will be successful given a request for additional information (to 2 decimals).
Answer:
1) 0.5
2)0.74
3) 0.65
Step-by-step explanation:
1) Since we are told that they had a 50-50 chance of getting the project, Thus;
Probability of a successful bid is;
P(Successful bid) = 50/(50 + 50) = 50/100 = 0.5
2) We are told that for 74% of the successful bids, the agency requested additional information. Thus;probability of a request for additional information given that the bid will ultimately be successful is;
P(request|successful) = 74% = 0.74
3) For us to find the posterior probability that the bid will be successful given a request for additional information will be gotten using bayes theorem to get;
P(successful|request) = [P(request|successful) × P(Successful bid)] / [(P(request|successful) × P(Successful bid)) + (P(request|unsuccessful bid) × P(unsuccessful bid))]
P(request|unsuccessful bid) is given as 0.39 and P(unsuccessful) will be 0.5.
Thus;
P(successful|request) = (0.74 × 0.5)/[(0. 74 × 0.5) + (0.39 × 0.5)] ≈ 0.65

Step-by-step explanation:
Michael is paid $9 per hour to work at the movie theater and $7 per hour when he helps his aunt at her bakery. Michael cannot work more than 32 hours in a week, but he wishes to earn at least $251 each week. Which weekly work schedule is within Michael’s constraints?
Answer:
The first one/$9 an hour job.
Step-by-step explanation:
For every 32 hours he works at the $9 per hour job he makes $288.
On the other hand, for every 32 hours he works at the $7 per hour job he only makes $224.
So the only one that'll work where he gets at least $251 is the $9 an hour job.
Hope this helps and have a nice day!
Answer:
C) 19 hours at the movie theater and 12 hours at the bakery

The bus fare in a city is People who use the bus have the option of purchasing a monthly coupon book for With the coupon book, the fare is reduced to $0.50. How many times must someone use the bus so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book? Express the total monthly cost to use the bus with a coupon book, f, as a function of the number of times in the month the bus is used, x. Then express the total monthly cost to use the bus without a coupon book, g, as a function of the number of times in the month the bus is used, x.
Answer:
26 times
Step-by-step explanation:
The question has missing details. However, the given parameters are
Given
Without Coupon
Bus Fare = $2.00
With Coupon
Coupon = $39.00
Bus Fare = $0.50
Represent the number of fares with x
Without Coupon, cost of fares is
Cost = 2x
i.e.
f(x) = 2x
With Coupon, cost of fares is
Cost = 39 + 0.5x
i.e.
g(x) = 39 + 0.5x
To calculate when both fares will be equal, we must have:
f(x) = g(x)
2x = 39 + 0.5x
Collect like terms
2x - 0.5x = 39
1.5x = 39
Solve for x
x = 39/1.5
x = 26
This implies that, for both cost to be equal, the person must go 26 times
