√(16) = 4 and √(25) = 5, so 4 + 5 = 9.

All values are the same, so variance = 0.

Mean = (1 + 2 + 3 + 4 + 5 + 6) / 6 = 3.5. Variance = [(1-3.5)² + (2-3.5)² + (3-3.5)² + (4-3.5)² + (5-3.5)² + (6-3.5)²] / 6 = 2.92 (approx 2.5).

Mean = 5. Variance = [(2-5)² + (4-5)² + (4-5)² + (4-5)² + (5-5)² + (5-5)² + (7-5)² + (9-5)²] / 8 = 6.

All values are the same, so variance = 0.

Mean = (5 + 7 + 9 + 11) / 4 = 8. Variance = [(5-8)² + (7-8)² + (9-8)² + (11-8)²] / 4 = 4.

All values are the same, so variance = 0.

All values are the same, so variance = 0.

To find the vertex, use the formula x = -b/(2a). Here, a = 2, b = -4, so x = 1. Substitute x = 1 into the equation to find y = -1.

The vertex can be found using x = -b/(2a). Here, x = 12/(2*3) = 2. Substituting x = 2 into the equation gives y = 3(2)^2 - 12(2) + 7 = -5.

The vertex can be found using x = -b/(2a). Here, x = 8/(2*2) = 2. Substituting x = 2 into f(x) gives f(2) = -3, so the vertex is (2, -3).

Volume = side^3 = 4^3 = 64 cubic units.

The volume of a cube is given by V = side³. For a side length of 5 cm, V = 5³ = 125 cm³.

Using the wind chill formula, Wind Chill = 13.12 + 0.6215*T - 11.37*(V^0.16) + 0.3965*T*(V^0.16), we find it to be approximately -15°C.

Work done (W) = Force (F) × Distance (d) = 15 N × 4 m = 60 J.

Work done = F × d × cos(θ) = 25 N × 4 m × cos(60°) = 25 N × 4 m × 0.5 = 50 J.

Work done (W) = PΔV = 1 atm * (2 L - 4 L) = 2 L·atm.

Work done = Fd cos(θ) = 25 N × 4 m × cos(60°) = 25 N × 4 m × 0.5 = 50 J

Work done (W) = F × d = 25 N × 8 m = 200 J.

Work done (W) = Force (F) × Distance (d) = 5 N × 3 m = 15 J.

To find the x-intercept, set y = 0. Thus, 2x = 6, giving x = 3.

To find the x-intercept, set y = 0. Thus, 4x = 20, giving x = 5.

Rearranging to y = (-2/5)x + 2, the y-intercept is 2.

Rearranging to slope-intercept form: -2y = -5x + 10, thus y = (5/2)x - 5. The y-intercept is -5.

Setting x = 0 in the equation gives -y + 8 = 0, thus y = 8.
