Answer:
11, 10, 9, 8
Step-by-step explanation:
To find the first 4 terms substitute n = 1, 2, 3, 4 into the expression, that is
12 - 1 = 11
12 - 2 = 10
12 - 3 = 9
12 - 4 = 8
The first 4 terms are 11, 10, 9, 8
Answer:
72.2 square meter
Step-by-step explanation:
(3.8)(3.8)= 14.44
(14.44)(5)=72.2
Answer:
0.01 is alpha level
Step-by-step explanation:
Given that a survey of a magazine of 1500 adults revealed that 12% chose chocolate pie.
i.e. p = proportion of people who like chocolate pie = 0.12
Margin of error = ±0.03
The value of q =1-\hat p , =1-0.12 = 0.88
The sample size n is given as 1500. Therefore, n=1500
The confidence level is given as 99%
Hence alpha = 1- confidence level
=1-0.99=0.01
Hence answer is 0.01
Answer:
Step-by-step explanation:
Based on the given conditions, write: 
Find common denominator and write numerators above common denominator: 
Calculate the sum or difference: 
Divide the fraction by multiplying its reciprocal: 
Calculate the product or quotient: 
Answer:
Solve for x:
x^9 = n x
Subtract n x from both sides:
x^9 - n x = 0
Factor x and constant terms from the left hand side:
-x (n - x^8) = 0
Multiply both sides by -1:
x (n - x^8) = 0
Split into two equations:
x = 0 or n - x^8 = 0
Subtract n from both sides:
x = 0 or -x^8 = -n
Multiply both sides by -1:
x = 0 or x^8 = n
Taking 8^th roots gives n^(1/8) times the 8^th roots of unity:
Answer: x = 0 or x = -n^(1/8) or x = -i n^(1/8) or x = i n^(1/8) or x = n^(1/8) or x = -(-1)^(1/4) n^(1/8) or x = (-1)^(1/4) n^(1/8) or x = -(-1)^(3/4) n^(1/8) or x = (-1)^(3/4) n^(1/8)
