Which set represents the range of the function shown? {(8,2),(6,5),(4,7),(11,-2)}

A.) {-2, 2, 5, 7}

B.) {4,6,8,11}

C.) {(2,8),(5,6),(7,4),(-2,11)

D.) {-2,2,4,5,6,7,8,11}

Answers

Answer 1

Answer:

Answer:

A.) {-2, 2, 5, 7}

Step-by-step explanation:

The range of a set of ordered pairs is the set of second numbers in the pairs.

Here, the second numbers are 2, 5, 7, -2. When written as a set, it is convenient (though not required) that they be written in numerical order:

{-2, 2, 5, 7} . . . . matches choice A

Answer 2

Answer:

Answer:

A.) {-2, 2, 5, 7}

What is ?

Express the answer in simplest form
what is 2 5/12 -(-2 1/6)

Answers

1 7/9 - 4/9

Convert 1 7/9 to an improper fraction:

16/9 - 4/9

Subtract the numerators together:

12/9

Convert to a whole number:

1 1/3

The answer is 1 3/9 which turns in to 1 1/3

The table below shows the distance y, in miles, traveled by a toy car in x minutes:Time (x)
(minutes) 20 30 40 50
Distance (y)
(miles) 5 10 15 20

Part A: What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and distance traveled by the toy car. (4 points)
[Choose the value of correlation coefficient from 1, 0.8, 0.5, 0.02]

Part B: What is the value of the slope of the graph of distance versus time, and what does the slope represent? (3 points)

Part C: Does the data in the table represent correlation or causation? Explain your answer. (3 points)

Answers

Part A: The correlation coefficient is 1. It means that the values of both x and y has a strong relationship giving them a avalue of 1.

Part B: The value of the slope of the graph is 0.5. the slope of the line represents how steep is the line of your graph

Part C: The data presented is correlation.

A hot air balloon descends at a rate of 320 feet per minute for 3 minutes. Use integers to calculate andrepresent the balloon's total change in altitude

Answers

Given:
descends at a rate of 320 feet per minute for 3 minutes.

320 feet per minute * 3 minutes = 960 feet

Total change in altitude is 960 feet. Since it is descending, I believe it would be a negative 960 feet.

negative 960 feet per minute
