Answer:
The perimeter of the trapezoid is
Step-by-step explanation:
we know that
The perimeter of the trapezoid is the sum of its four side lengths
so
In this problem
the formula to calculate the distance between two points is equal to
we have
step 1
Find the distance QR
substitute the values in the formula
step 2
Find the distance RS
substitute the values in the formula
step 3
Find the distance ST
substitute the values in the formula
step 4
Find the distance QT
substitute the values in the formula
step 5
Find the perimeter
Answer:
a) Sample of households using cell-phone only in a particular region or in a country.
b) It has to be Systematic sampling techniques
Step-by-step explanation:
a) Since the goal of the organization is to estimate the number of cell phone only households. Only households that uses cell-phone only is the appropriate population to sample from. The first step is to identify the households that fall into the population of interest. Then number them systematically and sample from the frame.
b) The moment an household is selected into the sample from the frame, the researcher can visit to conduct the survey. Or, he or she can use other method of data collection such as phoning the household before physical visit, etc.
Answer:
10 units
Step-by-step explanation:
The difference between the points is ...
z2 -z1 = (11 -11i) -(3 -5i) = (11 -3) +(-11 -(-5))i = 8 -6i
The magnitude of that difference is ...
d = √(8² +(-6)²) = √(64 +36) = √100 = 10
The distance between z1 and z2 is 10 units.
