Answer:
A significant negative relationship exists between the variables
Step-by-step explanation:
Base on the information given in the question which goes thus : For every unit increase in x, y decreases by 12.8094. The value 12.8094 is the slope which is the rate of change in y variable per unit change in the independent variable. The sign or nature of the slope Coefficient gives an hint about the relationship between the x and y variables. The slope Coefficient in this case is negative and thus we'll have a negative relationship between the x and y variables (an increase in x leads to a corresponding decrease in y). This is a negative association.
Answer:
1.179.17
Step-by-step explanation:
area of triangle= height*base/2=25.48
there are 4 triangles so multiply 25.48*4=101.92
Since it’s a regular octagon, all the sides are equal to = 4cm
Like shown above in the diagram, the sides of the octagon can be extended such that it forms a square.
According to Pythagorean theorem, x2 + x2 = 42; 2x2 = 16
x = √8cm
Total side length for the square= 4 + √8 + √8 = 9.657cm
Area of square= (9.657cm) 2 = 93.25cm2
Area of 4 triangles= 4 (1/2 * √8 * √8) = 16.0cm
Area of octagon, A = Area of square – Area of 4 triangles = 93.25 – 16.0 = 77.25cm2
now add 101.92+77.25=179.17
Answer:
117 degrees
so a line is 180 degrees so the 63 +x=180
find x
180-63=117
can u add the table so its easier
Answer:
An arithmetic sequence has a constant difference between each term. ... A geometric sequence has a constant ratio (multiplier) between each term. An example is: 2,4,8,16,32,… So to find the next term in the sequence we would multiply the previous term by 2.
