STATISTICS PLEASE HELP
Bingel [31]

Answer:

95

Step-by-step explanation:

If the mean is 400 and the standard deviation 12.5. It means that a range between 375 and 425 is the mean +- 2 standard deviations

400 - 12.5*2 = 375

400 + 12.5*2 = 425

Which means the probability is 95%

When you are looking for +- 1 deviation standard the probability is 68, and for +- 3 the probability is 99.7

There is a more complex explanation based on Z, but assuming you are only applying 68-95-99.7 rule this should be enough.

Answer:

1) 5

2) 9

Step-by-step explanation:

n2 - m

= -2(2) - (-9)

= -4 + 9

= 5

in - m2

Given the lines a and b are parallel and that m&lt;8=180, find
anygoal [31]

Answer:

  • D) 72°

Step-by-step explanation:

Sum of angles 7 and 8 is 180° as they are supplementary

Angles 7 and 3 are corresponding angles and they measure same as per property of corresponding angles, therefore:

  • m∠3 = m∠7
  • m∠7 = 180° - m∠8 = 180° - 108° = 72°
  • So m∠3 = 72°

Option D is correct
