The mean temperature was 80.83○F, with a standard deviation of 5○F. Based on this sample data, find the percentage of days that we can predict to be between 69○F and 78○F.

there is no graph so i cant sorry

step-by-step explanation:

c.

step-by-step explanation:

simple you would first have to get   a negative number where as 1 to be multiplied by 24 and then you would have to multiply 6 time 4 and then repeat that process until you reach your term

answer is  

a.

16.1

hope you got it chief.

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
