Answer:
√61 ≈ 7.81
Step-by-step explanation:
Distance formula:
√(x₂ - x₁)² + (y₂ - y₁)²
√(2 - (-4))² + (5 - 0)²
√(2 + 4)² + 5²
√6² + 5²
√36 + 25
√61
Answer:
One
Step-by-step explanation:
Answer: A.) Critical values: r= ± 0.514, no significant linear correlation
Step-by-step explanation:
r = 0.105
n = 15
The level of significance for a two-tailed test is 0.05
The degrees of freedom = n - 2 = 15 - 2 = 13
Using the pearson product moment correlation Coefficient table ; The critical value for the correlation Coefficient is ±0.513977
When the correlation coefficient (for a sample of 15 drawn from the same population) is less than ±0.514 (critical value), that means no significant linear correlation exists.
Answer:
there are no graphs
