150 lower level
200 upper level
Let x = lower level and y = upper level. You can then set up an equation for cost as:
35x + 25y = 10,250
and the equation for total tickets as:
x + y = 350.
Solve using any method.
Answer:
No Solution.
Step-by-step explanation:
y=3x-7
y=3x+4
-----------
3x-7=3x+4
3x-3x-7=4
-7=4
no solution.
Answer:
The region between one standard deviation from the mean is (400,600) which should be 68.27% of the data.
Step-by-step explanation:
The mean of this data set is 500 and the standard deviation is 100. The data that are within one standard deviation of the mean, must be in the range between 400 and 600, which according to the normal curve should be about 68.27% of the samples. The shaded region is shown in red on the attached figure.
Answer:
x = 12W
Step-by-step explanation:
Let x = power consumption of the LED bulbs.
Writing the ratio as a fraction;
Cross multiplying, we have;
x = 12
Therefore, the power consumption of the LED bulbs is 12W.
