Answer:
The size of the sample needed = 67.65
Explanation:
Given that :
The margin of error = 10% = 0.10
The confidence level = 90% = 0.90
Level of significance = 1 - 0.90 = 0.10
At ∝ = 0.10
Since the proportion of people that supported him/her is not given, we assumed p = 0.50
The margin of error formula can be expressed as:
Squaring both sides; we have:
n = 67.65
Therefore, the required sample size = 67.65
Answer:
Ratio of height of model to height of the actual Building = 5 : 614
Explanation:
Given:
ATT Building height = 614 feet tall
Model of building = 60 inches tall
Find:
Ratio of height of model to height of the actual Building
Computation:
ATT Building height = 614 feet tall = 614 x 12 = 7,368 inch
Ratio of height of model to height of the actual Building = Model of building / ATT Building height
Ratio of height of model to height of the actual Building = 60 / 7,368
Ratio of height of model to height of the actual Building = 5 : 614
D. salt and water do not produce a chemical reaction, rather a physical one, thats why the salt stays behind after the water disappears... because it never changed other than its physical appearance
Answer:
redox proteins can be attached to electrode surfaces in a “wired” configuration, that is, one that facilitates direct electron transfer. The feasibility of simple electroactive adsorption onto a range of electrode surfaces is illustrated, with a highlight on the recent advances that have been achieved in biotechnological device construction using carbon materials and metal oxides. The covalent crosslinking strategies commonly used for the modification and biofunctionalization of electrode surfaces are also evaluated. Recent innovations in harnessing chemical biology methods for electrically wiring redox biology to surfaces are emphasized.
