an = -9 -3(n-1)
Step-by-step explanation:
e = 2.7182818 so you can just plug that in to your calculator and solve like normal
Answer:
B
Step-by-step explanation:
12.25 times 11 is 134.75
488 times 0.21 is 102.48
134.75 plus 102.48 equals 237.23
237.23 is closest to 232 which is B.
Approximately 34% of a normal distribution is within 1 standard deviation above the mean. Your probability is about 100% - (50% +34%) = 16%.
