Answer:
or 1.414
Step-by-step explanation:
1) Find the mean. 1+2+3+4+5 = 15. 15/5= 3
2) For each data point, find the square of its distance to the mean. (4, 1, 0, 1, 4)
3) Sum the values from Step 2. 10
4) Divide by the number of data points. 10/5= 2
5) Take the square root.

Answer:
2
Step-by-step explanation:
Plug in 2 for c in the equation:
x² + 3x + 2
x 2
x 1
(x + 2)(x + 1)
Check. Use the FOIL method:
(x)(x) = x²
(x)(1) = x
(2)(x) = 2x
(2)(1) = 2
x² + x + 2x + 2
Combine like terms:
x² + (x + 2x) + 2
x² + (3x) + 2
2 can be a answer for c.

Answer: 74.6
we draw a right triangle ABC, have: ∠ABC = 90°, AB = 20 and ∠BAC = 75°, the height of the building is BC
we also have: tan 75° = BC/AB = BC/20
=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6
