1 3/4 = 7/4 + 1/3 =
7/4(3/3) + 1/3(4/4)=
21/12 + 4/12 = 25/12 = 2 1/12 yards

2. Kervins is $28 in debt because he borrowed money to buy food after school. He plans to pay back his debt at a rate of $7 per week. Which of the following equations best describes how many weeks it will take Kervins to pay off his debt?
(a) 28 +7 = 4
(b) - 28+ - 7 = - 4
(c) - 28 +- 7 = 4
(d) - 28+7 =-4
Find the sum.
(n+8)+(n−12)
=
n=2
Reorder terms:
(8+n)+(n-12)=0
Remover first parentheses :
8+n+(n-12)=0
Reorder (again):
8-12+n+n=0
Simplify:
-4+2n=0
Add 4 to both sides:
2n=4
Divide and you’re done!
n=2

Franco has a hat with 9 blue marbles, 4 yellow marbles, and 12 green marbles. He designs a binomial experiment by drawing a marble from the hat, recording whether the marble is green, and then laying the marble aside. He then repeat the process seven times. Which statement must be true?
A. The experiment is not a binomial experiment because there is not a fixed number of drawings.
B. The experiment is not a binomial experiment because the probability of choosing a green marble is the same for each drawing.
C. The experiment is not a binomial experiment because the probability of choosing a green marble is not the same fo each drawing.
D. The experiment is not a binomial experiment because there are only two possible outcomes for each drawing.
Answer:
C: The experiment is not a binomial experiment because the probability of choosing a green marble is not the same for each drawing.
Step-by-step explanation:
Just took the Binomial Distribution Quiz on Edge.
The experiment is not a binomial experiment because the probability of choosing a green marble is not same for each drawing
What is binomial experiment ?
An experiment consisting of a fixed number of independent trials each with two possible outcomes, success and failure .
The experiment is not a binomial experiment because the probability of choosing a green marble is not the same for each as after drawing the marble from hat , he is laying the marble aside and not putting it back into the hat which altered the probability every time because total number of marbles are decreasing after every turn of drawing.
hence , correct answer is
option c

Annabelle lives at Bermondsey in London. She has to speak at a conference inBirmingham at 10.30am.
It will take her an hour from her home to get to Euston Rail
Station, from where she will get a train to Birmingham.
The train journey from Euston
to Bimingham is an hour and 10 minutes.
Trains to Birmingham run at the following times: 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.
The meeting venue in Birmingham is a 5-minute walk from the station.
What is the latest time that Annabelle can leave home, if she is to make it on time for
the meeting in Birmingham
Show your work.
Please HELP!!! DUE TODAY!!
Thank you so much.
Answer:
7:45
Step-by-step explanation:
work backwards from 10:30!
u need 5 min to walk from meeting place to station, therefore u need to done riding the train by 10:25.
then u know that the train is an hour and 30 min, therefore u have to ride the train before or at 8:55 (10:25 minus an hour and a half)
the latest time for the train to leave is 45 min past the hour. therefore you will ride the 8:45 train.
since we already know that we are riding the 8:45 train by latest, you have to leave an hour early to get to the station. so you need to leave home by 7:45.
hope i was helpful !
The latest time that Annabelle can leave home is the she leaves home and she won't be late for her meeting
Time of meeting = 10.30am
Time she will spend before getting to meeting:
home to get to Euston Rail Station = 1 hourtrain journey from Euston to Bimingham = 1 hour 10 minutesTrains to Birmingham = 5 minutes past the hour, 25 minutes past the hour and 45 minutes past the hour.The latest time is 45 minutes
Walk from the meeting venue in Birmingham from the station = 5 minute walkTotal time = 1 hour + 1 hour 10 minutes + 45 minutes + 5 minutes
= 3 hours
Counting 3 hours backward from 10:30 am = 7:30 am
Therefore, the latest time Annabelle can leave home is 7:30 am

Consider matrix A.
What matrix results from the elementary row operations represented by −2R2+3R1?
Answer:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]
Step-by-step explanation:
Given the matrix
[tex]A = \left[\begin{array}{ccc}-3&3&2\\8&-1&3\end{array}\right] \\R1 = -3, 5, 2\\R2 = 8, -1, 3\\\\[/tex]
Before we can get the resulting matrix after the elementary operation, we need to get the new second row using the formula −2R2+3R1?
when R1= -3, R2 = 8
−2R2+3R1? = −2(8)+3(-3)
−2(8)+3(-3) = -16-9
−2(8)+3(-3) = -25
R1= 5, R2 = -1
−2R2+3R1? = −2(-1)+3(5)
−2(-1)+3(5) = 2-15
−2(-1)+3(5) = -13
when R1= 2, R2 = 3
−2R2+3R1? = −2(3)+3(2)
−2(3)+3(2) = -6-6
−2(3)+3(2) = 0
Hence the new R2 are -25, -13, 0
The resulting matrix will be:
[tex]A = \left[\begin{array}{ccc}-3&3&2\\-25&-13&0\end{array}\right][/tex]

How do you solve 5x + 7 = 2x + 1
Answer:
x = -2
Step-by-step explanation:
5x + 7 = 2x + 1
subtract both sides by 2x
3x + 7 = 1
subtract both side by 7
3x = -6
divide both sides by 3
x = -2
