Doss [256]

Solution:

The first car can travel 75 miles on 5 gallons of gas.

So  per mile gas consumed by car=\frac{5}{75}=\frac{1}{15} gallon

The second car can travel 240 miles on 20 gallons of gas.

So  per mile gas consumed by car=\frac{20}{240}=\frac{1}{12} gallon

It mean Sam should rent the First car.

Sam is renting one of two cars to go on a 300-mile trip.

So total number of gallons of gas required=\frac{1}{15}*300=20

Total cost of 20 gallons of gas =\frac{49.42}{14}*20= 70.6 dollar

EleoNora [17]

From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).

<h3>What is the correlation coefficient?</h3>

The correlation coefficient is a measure of how similar two datasets are acting.

When the correlation coefficient comes out as -1, it means that both the datasets are negatively oppositely correlated.

One data increases and other data starts to decrease in the opposite direction.

When the correlation coefficient comes out below 0, values are negatively correlated.

The correlation shown by the graph is negative.

From the graph, the coordinates of the cross that represent this car on the graph are ( 8, 2100).

A sample is BEST defined as _________.
Thepotemich [5.8K]

Answer:

(B) A selected group of participants that is representative of a larger population

Step-by-step explanation:

A sample statistic is a piece of information that you get from a fraction of the population. This information is representative of a larger population.

For example, someone wants to conduct a survey about the most popular NFL team in Syracuse, NY, if it is the Buffalo Bills or the New York Giants. This person is not going to ask each person for whom they cheer. They are going to collect data from a fraction of the population and this data will be expanded to include the entire population.

So, the correct answer is:

(B) A selected group of participants that is representative of a larger population
