The standard deviation is the square root of the variance so
square root 27 is 5.196152423
Answer:
Step-by-step explanation:
Volumes of two spheres A and B = 648 cm³ and 1029 cm³
Things to remember:
1). Scale factor of two objects = [ and are the radii of two circles]
2). Area scale factor =
3). Volume scale factor =
Volume scale factor Or Volume ratio =
Therefore, scale factor =
≈ 6 : 7
Area scale factor Or area ratio =
=
≈ 36 : 49
Volume scale factor or Volume ratio =
=
≈ 216 : 343
The value of y is equal to 2
Answer:
Option C.
Step-by-step explanation:
If a line passes through two points and , then the equation of line is
The line passes through the points (1,0) and (0,-2). So, the equation of line is
It is a solid line and the shaded region lies below the line, so the sign of inequality must be "≤".
First inequality is .
The parabola intersect the x-axis at 0 and 3, so the equation of of parabola is
It is a solid curve and the shaded region lies above the curve, so the sign of inequality must be "≥".
Second inequality is .
Therefore, the correct option is C.
