Answers
Answer:
The first yes, the second no.
Step-by-step explanation:
Proportional means they follow a constant proportion. In the first example, 1 hr is 4.5 ft, so the constant is 4.5, which means that everything in the top line multiplied by 4.5 should equal the bottom line. 2*4.5=9, 3*4.5=13.5, if you check it it all works out. But on the second problem, 2 hrs is 20 ft, which means that the constant should be 10, because 2/2 is 1 and 20/2 is 10, but 4*10 does not equal 30, it equals 40, so right off the bat we know it’s not proportional.

A gardener uses a total of gallons of gasoline in one month. Of the total amount
of gasoline, was used in his lawn mowers. How many gallons of gasoline did the
gardener use his lawn mowers in one month?
Answers
Answer:
D. 36.9
Explanation:
three-fifths of 61.5 is 36.9!
Answer:
D. 36.9
Step-by-step explanation:
The total amount of gallons the gardener typically uses in a month is 61.5 gallons. Since the gardener used 3/5 gallons, we know that 5/5 is 61.5 gallons. So you would have to divide 61.5 by 5 in order to get 1/5 of the gallons which would be 12.3. Then you have to multiply the 12.3 by 3 in order to get 3/5 of how much the gardener used which is 39.9 gallons. I hope this helped!

Nathan is using the random number string below in a simulation. He wants to determine how many people he has to meet before he finds one that is left-handed.
1 5 8 9 7 8 2 3 6 7 0 5 6 5 9 3 7 0 9 4
He lets each number in the string represent a person, with 0 representing left-handed people and 1 through 9 representing right-handed people. According to the simulation, how many people does he have to meet until he finds the first left-handed person?
Answers
Answer:11people
Step-by-step explanation:
For this question, ignore all numbers that are not 0 to start with, as 0 is the only number that shows you an individual who is left-handed. Now, take a look at where 0 is. How many numbers do you see before it? There are 10 numbers before 0, and if you add 1 more, there are 11 in total. The first left-handed person is the 11th person Nathan will meet.
The rule is x→y=−2x. c Can you mark all the points that fit the rule on a coordinate plane?
Answers
Step-by-step explanation:
Y=0,-2,2
X=-1,0,1
Since x represent y = - 2x
The points that fit the rule on a coordinate plane are (0, 0), (1, -2), (2, -4) and (3, -6)
Selecting the points that fit the rule on a coordinate plane?From the question, we have the following parameters that can be used in our computation:
Rule: x→y=−2x
Express properly
So, we have the following representation
Rule: x → y = −2x
As an equation, we have
y = -2x
Next, we set values for x and calculate the value of y
Using the above as a guide, we have the following:
x : 0 → y = −2(0) = 0
x : 1 → y = −2(1) = -2
x : 2 → y = −2(2) = -4
x : 3 → y = −2(3) = -6
So, the points that fit the rule on a coordinate plane are (0, 0), (1, -2), (2, -4) and (3, -6)

The table shows the results of 500 experiments. Each experiment involved one person choosing one card from each of two identic decks of cards, labeled 1 through 5. What is the experimental probability of a person choosing a 2, then a 3? Express the answer as percent. ( I really need help with this, I tried looking at my notes and my brain literally can’t function )
Answers
Unfortunately, I cannot see the table you mentioned. However, I can explain how to calculate experimental probability and apply it to the given situation.
Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted. In this case, the event is a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5.
Let's say we conducted 500 experiments, and in 50 of those experiments, a person chose a 2, then a 3. Then the experimental probability of choosing a 2, then a 3 is:
Experimental probability = (Number of times the event occurred) / (Total number of experiments) = 50 / 500 = 0.1
To express this as a percent, we simply multiply by 100:
Experimental probability as percent = 0.1 x 100% = 10%
Therefore, the experimental probability of a person choosing a 2, then a 3 from two identical decks of cards labeled 1 through 5, based on 500 experiments, is 10%.

Describe a rule for determining how much the store charges based on the number of turkey subs delivered.
Answers
The rule for determining how much the store charges based on the number of turkey subs delivered will depend on the pricing structure that the store uses. One possible rule is a linear function, where the cost of each turkey sub is a fixed amount and the total cost is proportional to the number of subs delivered.
For example, if the store charges $5 for each turkey sub, the rule could be:
Total cost = $5 per sub * Number of subs delivered
So if the store delivers 10 turkey subs, the total cost would be:
Total cost = $5 per sub * 10 subs = $50
If the store delivers 20 turkey subs, the total cost would be:
Total cost = $5 per sub * 20 subs = $100
This rule assumes that the cost per sub remains constant regardless of the number of subs delivered. However, in reality, the cost per sub may vary depending on factors such as the cost of ingredients and labor, and the store's desired profit margin.

Three park rangers had to report on the ways visitors use their facilities. Each ranger surveyed a sample of park visitors. Determine whether or not each sampling described is random or biased.
Answers
Answer:
To determine whether a sampling is random or biased, we need to know how the sample was selected. Here are three possible scenarios:
Ranger 1 stands at the entrance to the park and surveys the first 100 visitors who arrive.
This sampling is biased, as it only includes visitors who arrived early in the day. Visitors who arrive later in the day may have different characteristics or behaviors, so this sample may not be representative of all park visitors.
Ranger 2 selects every 10th visitor who enters the park and surveys them.
This sampling is random, as every 10th visitor is selected without bias. This method is called systematic sampling.
Ranger 3 surveys visitors who are leaving the park on a rainy day.
This sampling is biased, as visitors who come to the park on a rainy day may have different motivations or behaviors than visitors on a sunny day. This sample may not be representative of all park visitors.
In summary, sampling methods that are random, such as systematic sampling, are preferred over biased sampling methods in order to obtain a representative sample of the population of interest.
Answer: Depending on the situation
Step-by-step explanation: For a sample to be random, everyone/thing has to have an equal chance of getting selected. Ex. One of the park rangers asked everyone in one part of the park. - This example would be biased because the people who weren't in that part of the park had less of a chance of being picked

The number of times Maria drove the car on day 4 is 7 times.
How many times did Maria drive her car on day 4?A line graph is a graph that connects different data points on a graph using a straight line. A line graph is made up of a x-axis and a y-axis. In the line graph given, the number of days is on the x-axis and the number of times the car was driven is on the y-axis. A line graph is used to show quantitative data. Line graphs are used to visualise data.
In order to determine the number of times Maria drove the car on day 4, locate where day 4 is on the x-axis. Then trace 4 upward toward a data point. When the data point is located, trace it to the y-axis. When day 4 is traced to the y-axis, the value gotten is 7.
