Which graph has a coefficient correlation r closeest to -0.95
2 answers:
Answer:
Graph has a coefficient correlation r closest to -0.95 is the b).
Step-by-step explanation:
The correlation refers to the slope of a function and the sign indicates the direction to be linear the correlation informs us that it is inversely proportional
Taking some number to realice
Y axis maximum 5
X axis maximum 5
Notice 5 is where cut axis y so b=5
Equation:
Replacing:
x1=1.25; x2=2.5; x3=3.8;
So:
(1.25, 3.8); (2.5, 2.625); (3.8, 1.39)

Here is the complete question used in answering this question :
Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?
We first have to determine the fraction of the boats that are red
1 - ( +
)
1 -
1 -
1 - 1
= 9/28
so, 9/28 of the boats are red
let b represent the total number of boats
9/28 x b = 9
to find b, divide both sides of the equation by 28/9
b = 28
