The number of pieces of popcorn in a large movie theatre popcorn bucket is normally distributed, with a mean of 1515 and a standard deviation of 15. Approximately what percentage of buckets contain between 1470 and 1560 pieces of popcorn?

Approximately 68%
Approximately 75%
Approximately 95%
99.7%

99.7%

Step-by-step explanation:

1470 & 1560 are both 3 standard deviations from 1515, so it would mean that 99.7% of buckets contain between 1470 and 1560.

answer: the answer is simply nothing.

step-by-step explanation: because there is no ending to this question

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
