Solution Steps

Step 1: Analyze the First Row

The first row is for \(\mathrm{Ag}^{+}\).

  • Atom or Ion?: \(\mathrm{Ag}^{+}\) is a cation because it has a positive charge.
  • Number of Protons: Silver (Ag) has an atomic number of 47, so it has 47 protons.
  • Number of Electrons: Since it is a cation with a \(+1\) charge, it has one less electron than protons, so it has 46 electrons.
Step 2: Analyze the Second Row

The second row has 29 protons.

  • Atom or Ion?: An element with 29 protons is Copper (Cu).
  • Neutral Atom or Ion?: Since the number of protons is given, we assume it is a neutral atom unless specified otherwise.
  • Number of Electrons: A neutral atom has the same number of electrons as protons, so it has 29 electrons.
Step 3: Analyze the Third Row

The third row is missing information for a neutral atom.

  • Atom or Ion?: It is specified as a neutral atom.
  • Number of Protons: Since it is a neutral atom, the number of protons equals the number of electrons.
  • Number of Electrons: This information is missing, but it should match the number of protons for a neutral atom.

Final Answer

\[ \begin{array}{|c|cc|c|c|c|} \hline \text{symbol} & \multicolumn{3}{|c|}{\begin{array}{c} \text{atom or ion?} \\ \text{check-all that apply} \end{array}} & \begin{array}{c} \text{number of} \\ \text{protons} \end{array} & \begin{array}{c} \text{number of} \\ \text{electrons} \end{array} \\ \hline \mathrm{Ag}^{+} & \square \text{ neutral atom} & \checked \text{ cation} & \square \text{ anion} & \boxed{47} & \boxed{46} \\ \hline \mathrm{Cu} & \checked \text{ neutral atom} & \square \text{ cation} & \square \text{ anion} & \boxed{29} & \boxed{29} \\ \hline \square & \square & \text{neutral atom} & \square & \text{cation} & \square \text{ anion} \\ \hline \end{array} \]

Determine which numbers could not be used to represent the probability of an event. Select all that apply. A. -1.5, because probability values cannot be less than 0. B. 33.3%, this is because probability values cannot be greater than 1. C. 0.0002, because probability values must be rounded to two decimal places. D. 320/1058, because probability values cannot be in fraction form. E. 64/25, because probability values cannot be greater than 1. F. 0, because probability values must be greater than 0.

Sylvie surveyed a random sample of 50 subscribers to the fast bike magazines to find the number of bikes they own and the features of them. Of the subscribers, 10 own fewer than 3 vehicles. There are 400 subscribers to the fast bike magazines. Based on the above data, what will be the reasonable estimate for the number of subscribers of fast bike magazine who own fewer than 3 vehicles? What is the type of random sampling preferred to get the sample given that we do not have information of all 400 subscribers? 50, Stratified sampling. 40, Cluster sampling. 30, Simple random sampling. 80, Systematic random sampling.
