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.

Answer:
Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.
Step-by-step explanation:
Given that:
Scores of four tests
78, 89, 90 and 96
Let,
x be the score on fifth test.
Average is the sum of quantities divided by total number of quantities.
Average = 90
Average =
Putting the values in the formula;
Hence,
Jenny James would need to have a score of 97 out of 100 points in order to have an average of 90.
of his total sales in dollars, x, which can be represented by f(x) = 275 + 0.025x. Determine the
value of x, in dollars, that will make their weekly pay the same.
The possible area codes for different plan are .
Step-by-step explanation:
Given: In a different plan for area codes, the first digit could be any number from through, the second digit was either and the third digit could be any number except .
As mentioned in question:
Area codes are created by digits as:
first digit could be any number from through are .
Second digit are
And third digit couldbe any number except are .
Total number of area codes are .
Hence, the possible area codes are
Learn about possible codes here:
In a different plan for area codes, there are 140 possible codes.
In a different plan for area codes, the first digit could be any number from 4 through 8, the second digit was either 3, 4, 5, or 6, and the third digit could be any number except 2 or 5. To calculate the total number of possible area codes, we need to multiply the number of choices for each digit.
For the first digit, there are 5 choices (4, 5, 6, 7, 8).
For the second digit, there are 4 choices (3, 4, 5, 6).
For the third digit, there are 7 choices (0, 1, 3, 4, 6, 7, 8).
To find the total number of possible area codes, we multiply these choices together: 5 x 4 x 7 = 140.
