Answer: b) τ = 0.3
Step-by-step explanation:
Given the data :
Amount of salt (x)____% body fat(y)
0.2 _______________20
0.3 _______________30
0.4 _______________22
0.5 _______________30
0.7 _______________38
0.9 _______________23
1.1 ________________30
The correlation Coefficient as obtained from the online pearson correlation Coefficient calculator is 0.3281 = 0.3 (to one decimal place) which implies that a weak positive correlation or relationship exists between the preferred amount of salt taken to the percentage body weight of an individual. This is because the value is positive and closer to 0 than 1. The closer the weaker the degree of correlation. With positive values implying a positive relationship (that is an increase in variable A leads to a corresponding increase in B and vice-versa).
36 = 3/4
12 = 1/4
48 = 4/4
The original price was $48
Answer:
This is the other ray that will make up the angle ∠AYZ and will complete the construction.
Step-by-step explanation:
The point of the construction is to copy the angle. That is, the end result must be an angle with identical measure to the original. The construction so far has no angle at Y. Drawing ray YA will complete the construction and create the desired angle. That is, YA ...
This is the other ray that will make up the angle ∠AYZ and will complete the construction.
Answer:
The value of p = -14
Step-by-step explanation:
Given the equation
Divide both sides by -6
simplify
Subtract 8 from both sides
simplify
Therefore,
The value of p = -14
The formula for direct variation is y = k × x and the formula for inverse variation is y = k/x
The direct variation represented by the equation
y ∝ x
Its is y directly proportional to x
Where x is the independent variable
y is the dependent variable
By replacing the ∝ sign with the equal sign. The equation will be
y = kx
Where k is the constant of proportionality
Similarly the inverse variation is
y ∝ 1/x
Replace the ∝ sign with the equal sign
y = k/x
Therefore, the direction variation represented by y = k × x and inverse variation represented by y = k/x
