What is the probability of getting at least one A

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

vince wrote the sequence below.

1/3, 1, 5/3, 7/

which of the following explains whether the sequence is geometric?

the sequence is geometric because 2/3 was added to each term to get the next term.

the sequence is geometric because 3 was multiplied to each term to get the next term.

the sequence is not geometric because 2/3 was added to each term to get the next term.

the sequence is not geometric because 3 was multiplied to each term to get the next term.

step-by-step explanation:

during a construction project, engineers used explosives to excavate 140 feet of tunnel into a mountain. but because of time constraints and environmental concerns, they brought in a tunnel boring machine (tbm) to excavate the rest of the tunnel. the data table lists some observations an engineer made about the length of the tunnel after the tbm was introduced.

which equation represents the length of the completed tunnel based on the number of days since tbm was introduced?

the answer is y = 45x + 140
