Answer:
(d) WEAK NEGATIVE ASSOCIATION.
Step-by-step explanation:
Pearson correlation (r) is defined as a factor which measures the linear dependence between two variables (x and y). It's also known as a parametric correlation.
Here, r = -0.19
Now, as r is NEGATIVE.
⇒ As the value of x increases , value of y decreases.
⇒There is a NEGATIVE ASSOCIATION.
Now as the value of r is between 0 and ( -1). So the factor of variation is very small.
Hence, it is WEAK NEGATIVE ASSOCIATION.
Answer: the answer is 12.3
Step-by-step explanation:
Just do 15/100(82)
Answer:
90%
Step-by-step explanation:
convert the fraction know as a ratio to get 90%
Answer:
y = 10
Step-by-step explanation:
40 = 4y
y = 40 : 4
y = 10
I don't know where the angle β is, so I will make the assumption that tanβ = h/r
V volume = 60
r radius = 2
h = r tanβ
