The correlation coefficient of the data provided is -0.52.
<h3>What is the correlation coefficient?</h3>
Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.
Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.
Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52

Answer:
see below
Step-by-step explanation:
x ≤ 3
There is a closed circle at 3 because of the equals sign
the lines goes to the left since it is less than
x < 3
There is a open circle at 3 because there is no equals sign
the lines goes to the left since it is less than
Answer:
1 inch = 3 feet
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
6 /2 = 3
1 in = 3 feet
Answer:
g(4) = 157
Step-by-step explanation:
g(x) = 8x^2 + 9x - 7
Let x =4
g(4) = 8 * 4^2 +9*4 -7
=8*16 +36 - 7
=128+36-7
=157
Answer:
x=8
Step-by-step explanation:
this is an equilateral triangle, which means all sides are equal
if all the sides are equal, all the angles are equal
the three angles are all equal to 60 degrees (180/3 = 60)
7x+4 = 60
subtract 4 from each side
7x = 56
divide by 7 on each side
x = 8
