When we say a statistic is resistant, we mean the extreme values do not affect the statistic to a large extent or to an extent which makes a major difference. Mean and median are example of such statistics. By changing the extreme values we do not see a substantial difference in the value of mean and median for the data set.
Consider a sample: 1,2,3,4,4,5,6,7,8
The median for this data set is 4.
If we change the extreme values to get this sample: -5,2,3,4,4,5,6,7,100
The median will still be the same i.e. 4. This is what is meant by a resistant statistic.
So option a is the correct ans.
Answer:
The length is 16.1 ft and the width is 4.7 ft
Step-by-step explanation:
Let
x -----> the total length of the tables
y -----> the width of the tables
we know that
The area is equal to
so
-----> equation A
-----> equation B
substitute equation B in equation A
Solve the quadratic equation by graphing
The solution is
Find the value of x
therefore
The length is 16.1 ft and the width is 4.7 ft

Complete question :
Solve the compound interest problem. $3425 is invested at %7.5 compounded monthly for 2 years. a. Find the overall amount. b. Find the compound interest.
Answer:
$3977.425 ; $552.425
Step-by-step explanation:
Given that:
Principal (P) = $3425
Rate (r) = 7.5% = 0.075
Time(t) = 2 years
A = p(1 + r/n)^nt
r = rate
n = number of times compounded per year
t = time in years
A = final amount
A = 3425(1 + 0.075/12)^12*2
A = 3425(1 + 0.00625)^24
A = 3425(1.00625)^24
A = 3425(1.1612920)
A = $3977.4251
Hence, overall amount = $3977.425
Compound interest = $(3977.425 - 3425) = $552.425
