Answer: 1 2/3 yards for each bow
Step-by-step explanation:
8 1/3 divided by 5 = 25/3 * 1/5 = 5/3
A.) There is likely an association between the categorical variables because the relative frequencies are similar in value.
B.) An association cannot be determined between the categorical variables because the relative frequencies are similar in value.
C.) An association cannot be determined between the categorical variables because the relative frequencies are not similar in value.
D.) There is likely an association between the categorical variables because the relative frequencies are both close to 0.50.
If the relative frequencies are 0.48 and 0.52, we conclude that: A. There is an association between the categorical variables because they are similar in value.
A two-way frequency table can be defined as a type of table that is used for the graphical representation of frequencies (relative frequencies) that are associated with two (2) categorical variables.
This ultimately implies that, a two-way frequency table can be used to show, analyze, and examine the relationships that exists between two (2) categorical variables.
In conclusion, we can conclude that there is an association between the categorical variables because the relative frequencies have the same (similar) value, especially if theyare 0.48 and 0.52.

Answer:
The first reactant takes approximately 147 seconds to reach half its initial concentration, while the second reactant takes approximately 214.5 seconds for the same reduction, based on their half-lives and initial concentrations.
Step-by-step explanation:
The rate constant (k) for a first-order reaction can be calculated using the formula:
k = (0.693) / t_half
For the first set of data:
k₁ = (0.693) / 147 s ≈ 0.00472 s⁻¹
For the second set of data:
k₂ = (0.693) / 215 s ≈ 0.00322 s⁻¹
Now, you can use these rate constants to calculate the time it takes for each reactant to reach a certain concentration. For example, if you want to find the time it takes for the first reactant (initial concentration = 0.294 M) to reduce to 0.147 M (half its initial concentration), you can use the following equation for a first-order reaction:
ln(C_t / C₀) = -kt
Where:
C_t = concentration at time t
C₀ = initial concentration
k = rate constant
t = time
For the first reactant:
ln(0.147 / 0.294) = -0.00472t
Solving for t:
t ≈ 147 seconds
For the second reactant (initial concentration = 0.201 M) to reduce to 0.1005 M (half its initial concentration):
ln(0.1005 / 0.201) = -0.00322t
Solving for t:
t ≈ 214.5 seconds
So, it takes approximately 147 seconds for the first reactant to reach half its initial concentration, and approximately 214.5 seconds for the second reactant to do the same, based on their respective half-lives and initial concentrations.
