It could be D or C
The system has two solutions
x = .8 y = .6
OR if you think about it , (x=.8 y=.6) could be considered THE solution.
I would go with choice C
Answer:
II case.
Step-by-step explanation:
Given that a catering company prepared and served 300 meals at an anniversary celebration last week using eight workers.
The week before, six workers prepared and served 240 meals at a wedding reception.
Productivity is normally measured by number of outputs/number of inputs
Here we can measure productivity as
no of meals served/no of workers
In the I case productivity =
In the II case productivity = 
Obviously II case productivity is more as per worker 40 meals were served which is more than 37.5 meals per worker in the I case.
Y = 5.5x is a linear equation (i.e. the highest power of the variables is 1). Therefore, the line will be a straight line with a slope of 5.5
D is the correct answer
good luck
Answer:
Probability of people order a salad or an appetizer P(A∪B) = 62%
Step-by-step explanation:
Given:
Probability of appetizer P(A) = 55%
Probability of salad P(B) = 25%
Probability of choose both P(A∩B) = 18%
Find:
Probability of people order a salad or an appetizer P(A∪B)
Computation:
P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∪B) = 55% + 25% - 18%
P(A∪B) = 62%
Probability of people order a salad or an appetizer P(A∪B) = 62%
