Answer:
A) = 1, = 4
B) = 2 + 2
C)
Step-by-step explanation:
For n ≥ 1 ,
S is a set containing 2^n distinct real numbers
an = no of comparisons to be made between pairs of elements of s
A)
= no of comparisons in set (s)
that contains 2 elements = 1
= no of comparisons in set (s) containing 4 = 4
B) an = 2a + 2
C) using the recurrence relation
a = 2a + 2
substitute the following values 2,3,4 .......... for n
a = 2a + 2
a = 2a + 2 =
a =
= ---------------- (x)
since 2^1 + 2^2 + 2^3 + ...... + 2^n-1 =
applying the sum formula for G.P
Note ; a = 2, r =2 , n = n-1
a1 = 1
so equation x becomes
Answer:
constructing a 90% confidence interval
Step-by-step explanation:
quizlet
at a 95% confidence interval By use of the table we have a critical value of 1.96, and so the margin of error is 1.96/(2 √ 900 = 0.03267, or about 3.3%.

A 90% confidence interval has a z-score (a critical value) of 1.645. In conclusion, the margin of error is 2.52%.

Answer:
x=-1
Step-by-step explanation:
So the first thing we need to do is set up an equation (using x to represent the number). Then, we'll solve it to get the answer.
Step 1: Translate the word problem into an equation
Word problem: The sum of nine and six-tenths and a number is thirteen and two-tenths.
Equation: + x =
Step 2: Isolate x by subtracting from each side
+ x - = -
Step 3: The numbers on the left cancel out, leaving x alone
x =
Step 4: Convert the answer to decimals
x = 3.6
-5x I’m pretty sure is correct
