Answer:
Margin of error = 0.01344
Step-by-step explanation:
Margin of error = critical value × standard deviation.
critical value for 95% confidence interval = 1.96
Standard deviation = √[(p)(q)/n]
p = 0.4, q = 1 - p = 1 - 0.4 = 0.6, n = 5100
Standard deviation = √[(0.6×0.4)/5100] = 0.00686
Margin of error = 1.96 × 0.00686 = 0.0134
Answer:
24) A
22) B
Step-by-step explanation:
24)
Original Price: d
Sale: 30%
A sale means that a value is subtracted from the original price
d - 30% = 0.7d
All options given:
A) 0.3d
B) 0.7d
C) d - 0.3d = 0.7d
D) (1.0 - 0.3)d = 0.7(d) = 0.7d
All of these options are equal to the price after the sale, except A.
A is the answer to question 24
22) m > 0, n > 0 Use an example to represent m and n
m = 1, n = 2 = -0.5
-0.5 is a rational, negative number
The answer to question 22 is B
Hope this helps :)
