Step-by-step explanation:
the process is shown in the picture.
Notice it is +/-4 times standard deviation (0.65-0.04 = 0.61, 0.69-0.04=0.65)
That's almost everything. So (D) is the answer.

Answer: Circumference of circle = 27.004 inches
Area of circle = 58.0586 inches²
Step-by-step explanation:
Diameter of circle = 8.6 inches
Pi (
) = 3.14
Circumference of circle (With diameter) = 
d (×diameter)
= 3.14 × 8.6
= 27.004 inches
Area of circle (With diameter) = 
/4
= 3.14 × 8.6 × 8.6 / 4
= 3.14 × 73.96 / 4
= 58.0586 inches²
Answer:
x=-(9+1y)/2
y=-2x-9
Step-by-step explanation:
2x=-9-1y
x=-(9+1y)/2
-1y=2x+9
y=-2x-9
Answer:
1. sometimes true
A rhombus is a quadrilateral with all equal size and length. A square is a quadrilateral with all equal size and length, and all right angles around bus, however, can be a square if it has right angles.
2. always true
A square has to have all equal sides and all right angles, however, a rectangle has to have right angles and opposite sides are equal to each other. So if a square has equal sides, it can be considered a rectangle since both opposite sides are equal
3. sometimes true
A parallelogram is a quad roulette or with parallel and equal opposite sides, and a rectangle has right angles and equal opposite sides, therefore, if the parallelogram has right angles, then it is considered a rectangle
4. always true
A quadrilateral has to have 4 sides and the rectangle has 4 sides there, for it is considered a quadrilateral
5. never true
A parallelogram is a quadrilateral, therefore, it has to have 4 sides, but a hexagon has to have 6 sides, therefore, it is never a hexagon
