About 81% of the world's population can roll their tongue. what is the probability that in a random sample of 2,000 people, more than 1,600 of them can roll their tongue?

0.8729

Step-by-step explanation:

This is the only answer choice that made sense to me, and I just took the quiz and I got it correct.

Please mark me the brainliest!?!

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
