To determine whether the bear population is proportionally related to the number of years, we can compare the ratios in the table. Looking at the first two rows, we have ratios of 3:1 and 6:2, which are equivalent (both reduce to 3:1). However, the ratio in the last row is 9:3, which does not reduce to 3:1. Therefore, the ratios are not equivalent and we can conclude that the bear population is not proportionally related to the number of years.
So, the correct answer is:
The bear population is not proportionally related to the number of years because the ratio in the last row is not equal to the ratios in the first two rows.
One biologist claimed that the bear population was proportionally related to the number of years after they were reintroduced into the wild. Based on the information in the table, would you agree? Explain your answer.

One worker earns $85 in 2 weeks, and another earns $175 in 4 weeks. Are the pay rates proportional?(1 point)

No, because the ratios of weeks to dollars cannot be reduced.
To determine if the pay rates are proportional, we need to compare the ratios of dollars to weeks for both workers.
The first worker earns $85 in 2 weeks, which can be written as the ratio 85:2. The second worker earns $175 in 4 weeks, which can be written as the ratio 175:4.
To check if the ratios are equivalent, we can reduce them to their simplest form.
The ratio 85:2 can be reduced to 42.5:1, while the ratio 175:4 can be reduced to 43.75:1.
Since the ratios 42.5:1 and 43.75:1 are not equivalent, we can conclude that the pay rates are not proportional.
Therefore, the correct answer is:
No, because the ratios of dollars to weeks are not equivalent.
The first worker earns $85 in 2 weeks, which can be written as the ratio 85:2. The second worker earns $175 in 4 weeks, which can be written as the ratio 175:4.
To check if the ratios are equivalent, we can reduce them to their simplest form.
The ratio 85:2 can be reduced to 42.5:1, while the ratio 175:4 can be reduced to 43.75:1.
Since the ratios 42.5:1 and 43.75:1 are not equivalent, we can conclude that the pay rates are not proportional.
Therefore, the correct answer is:
No, because the ratios of dollars to weeks are not equivalent.
A car travels 110 miles/2 hours . What is the unit rate?(1 point)
Responses
110 miles per 2 hours
110 miles per 2 hours
one mile per 55 hours
one mile per 55 hours
2 hours per 110 miles
2 hours per 110 miles
55 miles per hour
Responses
110 miles per 2 hours
110 miles per 2 hours
one mile per 55 hours
one mile per 55 hours
2 hours per 110 miles
2 hours per 110 miles
55 miles per hour
To find the unit rate, we need to divide the distance (in miles) by the time (in hours).
In this case, the car travels 110 miles in 2 hours, so the unit rate is 110 miles per 2 hours.
Therefore, the correct answer is:
110 miles per 2 hours.
In this case, the car travels 110 miles in 2 hours, so the unit rate is 110 miles per 2 hours.
Therefore, the correct answer is:
110 miles per 2 hours.

The prompt does not provide the prices for the two different-sized bags, so we cannot determine which size is a better deal based on the information given.
Therefore, none of the provided responses are correct.

is it b
I apologize if my previous response was not clear. Response b states "The 5-lb. bag is the better deal because 5 lb. is more than 2 lb."
Without knowing the prices of the two different-sized bags, we cannot determine which size is a better deal based solely on the weight. It is possible that the 2-lb. bag could be priced lower and therefore provide a better deal, regardless of the difference in weight.
Therefore, response b is not the correct answer.
