I think in order to answer we have to the options
First subtract the number that did, to find the number that didn't.
1300 - 520 = 780 customers did not order coffee.
Now divide the number who didn't order coffee by total number of customers:
780 / 1300 = 0.6
Multiply by 100 to get the percent:
0.6 x 100 = 60% did not order coffee.
Cot 8° 13'=cot(8+13/60)
=cot(8+.216......)
=cot8.216......
=cos/sin8.216......
=6.925...........
Answer:
domain= {x/x€R/x≠0}
Step-by-step explanation:
Answer: 145
Step-by-step explanation:
