Answer:
distributive property
Step-by-step explanation:
The distributive property is described as
a(b + c) = ab + ac
5(12 - 4) = 5(12) - 5(4) ← is obtained using the distributive property
Cody ALONE = 8 hours
Kaitlyn ALONE = 6 hours
Let Joseph ALONE take j hours
Cody ALONE in 1 HOUR = 1/8 of the work Kaitlyn ALONE in 1 hour = 1/6 of the work Joseph ALONE in 1 HOUR = 1/j of the work
Since TOGETHER they take X hours, in 1 hour TOGETHER they complete 1 / X of the work
1/8 + 1/6 + 1/j = 1/X
1/j = 1/X - 1/8 - 1/6 = (24 - 3X - 4X ) /24X = (24 - 7X ) / 24X
j = 24X / ( 24- 7X )
After completing the work value of X will be known , calculate j from the above formula ANSWER
Your answer would be 23.85 but I presume they rounded up so it would be 23.9
Answer:
121
Step-by-step explanation:
Given data as per the question
Standard deviation = 
= 840
Margin of error = E = 150
Confidence level = c = 95%
For 95% confidence, z = 1.96
based on the above information, the minimum number of clients surveyed by the travel agent is
= 120.47
= 121
hence, the 121 number of clients to be surveyed
Therefore we applied the above formula to determine the minimum number of clients
