The manufacturer of a brand of 6 mm rope wants to compare the breaking strength of the ropes manufactured using two different processes (A and B). Ten ropes manufactured by each of the two processes were randomly selected and tested for breaking strength. The data are shown in the below. Process A: 1470, 1515, 1510, 1545, 1480, 1580, 1435, 1575, 1475, 1540
Process B: 1485, 1500, 1525, 1455, 1570, 1560, 1530, 1550, 1515, 1510
Is this convincing evidence that the true mean breaking strength for 6 mm ropes manufactured using process A is different from the true mean breaking strength for 6 mm ropes manufactured using process B?

over the argument its not good to fight.

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)

i believe the answer is y=0.25x+-3

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
