27 multiplied by 8 is 216 so she would need a total of 216 cans. If each of the 23 students brings nine cans (multiple 23 by 9) then she has a total of 207. The difference is 9... so she needs 9 more cans
Answer:
False
Step-by-step explanation:
We are given the following in the question:
Pearson correlation = 1.30
Pearson coefficient:
- The range of Pearson coefficient is from [-1,1]
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
Since, the given coefficient of Pearson does not lies in the range, it cannot express relation between two quantities.
Thus, a value of 1.30 does not indicates a strong correlation.
Thus, the given statement is false.
Answer:
x = 5√5
Step-by-step explanation:
x² + 10² = 15²
x² + 100 = 225
x² = 125
x = √125
x = 5√5
