The correlation coefficient r of the data set is <em>-0.28</em>
Answer:
The answer is <u>D: lll and IV only</u>
Step-by-step explanation:
A. (0,-6)
plug in the area to the area formula for a triangle (A=1/2bh). so 28=1/2b(4) [since the height is 4]. divide by 4 (7=1/2b). multiply by 2/divide by 1/2 (14=b). the base equals 14 units long.
B. y=2/3x+4
find the slope of the line (2/3)
the y-intercept is 4
Answer:
Option C, The faces of all prisms are parallelogram
Step-by-step explanation:
A prism is a form of parallelogram and all its faces are also parallelogram.
The base of a prism is parallelepiped. The base can be of shape of any polygon such as triangle, square, rectangle etc. while the other faces are parallelograms or rectangles
Hence, it can be said that the faces of all prisms are parallelogram
Option C is correct
