Answer:
we know that
The radicand of the function must be greater than or equal to zero
so
the solution is the interval---------> [-6,∞)
therefore
the answer is
The domain are all values of x greater than or equal to minus six
Answer:
0.35
Step-by-step explanation:
Given the data:
Selling Time___ Frequency
0 10____________3
10 20__________ 4
20 30__________ 6
30 40__________ 4
40 50__________ 3
Proportion of selling time in sample above that are less Than 20 days :
Taking the sum of the frequency :
Hence, total frequency = (3 + 4 + 6 + 4 + 3) = 20
Selling time which is less Than 20 days :
(0 - 10) = 3
(10 - 20) = 4
Total = (3 + 4) = 7
Proportion = selling time less Than 20 days / total frequency
= 7 / 20
= 0.35
0.6 is the decimal for 9/15
