Answer:
circumcenter
Step-by-step explanation:
Suppose the three food trucks points a,b,c are joined together in such a way that the form a triangle. The perpendicular bisectors of the triangle are concurrent . The point of concurrency is called <u>circumcenter.</u>
According to the circumcenter theorem the points ( vertices of the triangle a,b,c) are equidistant from the center D ( point of concurrency) called the circumcenter.
As the food distributor is equidistant from each of the trucks it lies at the circumcenter point of concurrency.
The drawing is just a generalizations to give an idea. It does not show actual bisectors perpendicular.
Answer:
12x-15
Step-by-step explanation:
Let
x ---> total hours worked this week
we know that
To find out how much money Sunny earned this week , multiply the total hours worked by the rate of $12 per hour and subtract $15 for a late delivery
so
12x-15
Answer:
Step-by-step explanation:
a - 2.5 = 4.5
2.5 = 2.5
a = 7.0 or 7
7.0 - 2.5 = 4.5
4.5 = 4.5
Answer:
a: 1037 is the minimum sample size needed
b: 712 is the minimum sample size needed
Step-by-step explanation:
We need to use the formula for minimum sample size of a proportion when a sample proportion is known.
The level of confidence is 99%, which has a corresponding z-value of 2.575.
We know the desired error is 4%, or 0.04.
Part a: We have no prior estimate. See attached photo for calculation
Part b:
We know p-hat = 0.22. Therefore q-hat = 1 - 0.22 = 0.78
See the attached photo for the calculation of the minimum sample size
