Based on the information given, it should be noted that the probability that the proportion of voters that will support the ballot measure will be greater than 0.50 is 0.0895.
<h3>
How to calculate the probability.</h3>
From the information given, it was stated that a polling agency is investigating the voter support for a ballot measure in an upcoming city election and that the the population proportion of voters who would support the ballot measure in region a is 0. 47.
Based on the complete information, the probability that the proportion of voters in the sample of region A that will support the ballot measure will be greater than 0.50 will be given as P(Z > 1.3441).
It should be noted that when this value is looked in the table, it will give a value of 0.0895.

Answer:
B. CH₅N
Explanation:
The combustion reaction of a compound CₐHₓNₙ with O₂ is:
CₐHₓNₙ + O₂ → a CO₂ + X/2 H₂O + n NO₂
Where 1 mole of CₐHₓNₙ with an excess of O₂ produce a moles of CO₂, X/2 moles of H₂O and n moles of NO₂
Thus, you need to convert the mass of CO₂ and H₂O to moles to find the C:H ratio and determine a possible empirical formula thus:
Moles CO₂ (Molar mass 44g/mol):
44g ₓ (1mol / 44g) = 1 mole CO₂ = 1 mole C
Mole of H₂O (Molar mass 18g/mol):
45g ₓ (1 mol / 18g) = 2.5 moles H₂O = 5 moles H
Thus, in the compound you have 5 moles of H per mole of C, and a possible empirical formula is:
B. CH₅N
The only structure that meet this C:H ratio
