Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion
= 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
(From the z tables)
The margin of error is calculated by using the formula:




M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%
Answer:
fred = 45 books
sally has 27 times more book than fred
sally = 45 X 27
= 1215 books
340x100=34,000 hope this helps
Answer:
27, 12, and 36 = 108
22 and 4 = 44
14 and 12 = 84
25 and 8 =200
9, 8, and 7 = 504
32, 24, and 18 = 288
Step-by-step explanation: You are welcome.
Supplementary angles are two angles whose measures sum to a 180 degrees and complementary are the sum have to add up to 90 degrees.So 180÷2=90;90÷2=45;180÷6=30 and 90÷6=15.Altough the answer is A.
