A teacher is assessing the correlation between the number of hours spent studying and the average score on a music test. The table shows the data: Number of hours spent studying
(x) 0 0.5 1 1.5 2 2.5 3 3.5 4
Score on music test
(y) 60 62 64 66 68 70 72 74 76

Part A: Is there any correlation between the number of hours students spent studying and the score on the music test? Justify your answer. (4 points)

Part B: Write a function that best fits the data. (3 points)

Part C: What does the slope and y-intercept of the plot indicate? (3 points)

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

a) 32pie square meters

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
