Answer:
A correlation coefficient of +1 or -1 reflects a perfect linear relationship, but a 0.94 indicates a strong positive correlation between the aspen leaf's length and surface area, though not guaranteeing linearity.
Step-by-step explanation:
The correlation coefficient (r) ranges between +1 and −1, where +1 means perfect positive correlation, −1 means perfect negative correlation, and 0 means no correlation.
The closer r is to ±1, the stronger the correlation. Generally, values between 0.7 and 1, or −0.7 and −1, indicate a significant correlation.
While 0.94 shows a strong direct association between the leaf's length and surface area, it does not definitively prove a linear relationship is the best fit.
Answer:
24 minutes
Step-by-step explanation:
Let y represent the rate of 120 envelopes per minute.
40/8 = 120/y
40y = 8 * 120
40y = 960
y = 960/40
= 24 minutes
It could be either C or D, but I think C is the correct choice.
The query arises from an activity that must be completed to acquire the letters filling in the answer. After participation in this activity, the response to why the cow provided only buttermilk is "What else can she provide but her milk." The phrase "But-her-milk" is a play on words with "buttermilk." I hope this clarification assists you.
