Answer:
t = 3.46 hours, or 3 hours 28 minutes
Step-by-step explanation:
78 dozen donuts in 2 hours immediately reduces to 39 dozen/hour.
Donuts produced as a function of time: D(t), where t is the number of hours the macine runs.
Set D(t) = 135 dozen = (39 dozen/hr)t.
Solving this equation for t, we get:
t = 135/39 hours, or t = 3.46 hours, or 3 hours 28 minutes
E ∩ F = {}
Step-by-step explanation:
Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,
Given
E = {1, 2, 3}
F = {101, 102, 103, 104}
We have to find the intersection of both sets as indicated
So,
E ∩F = {1, 2, 3} ∩ {101, 102, 103, 104}
E ∩ F = {}
As there are no common elements in both sets the intersection will be an empty set

Step-by-step explanation:
First, we may wonder, what does the term <em>margin of error</em> mean? Put simply, the margin of error is a measure of the degree to which research results do not reflect the views of the total studied population. In other words, it tells readers how much confidence they should have in the results presented.
It has often been suggested that a fundamentally and conceptually effective way that is always under the control of the researcher of making the margin of error smaller is to<em> increase the sample size</em> of the research. This basically involves collecting more sample data which thus leads to a closer estimate of the view of the entire population.
