Answer:
d. Correlation
Step-by-step explanation:
Based on the information being provided it can be said that this technique provides the correlation between two or more variables. Correlation explains any statistical relationship that exists between two different variables or sets of data, whether it is casual or not. Many times it is the degree to which a pair of variables are linearly related
Answer:
a. x=7 b. x= 4.5 c. c= 3
Step-by-step explanation:
a. 5x=35
5x/5=35/5
x = 7
b. 4x=18
4x/4=18/4
x=4.5
c. 6c-2c=12
4c = 12
4c/4 = 12/4
c=3
Answer:
Slope intercept form is y = 2x-4
Step-by-step explanation:
Given equation: 2y + 2 = 4x - 6
The general form of slope intercept form is y = mx+c
2y + 2 = 4x - 6
2y = 4x - 6 -2
2y = 4x -8
dividing throughout by 2
y = 2x -4
Hence the slope intercept form is y = 2x -4

The given triangle is a right triangle.
The tangent of an angle of right triangle is obtained by dividing the opposite side of the angle with the adjacent side of the angle.
The opposite side of angle R is 5 cm and the adjacent side of angle R is 12 cm.
tan R = 5 / 12 = 0.4167
R = arctan (0.4167) = 22.6 degrees.
