21 is the answer i think idk try dividing them all or finindng something or look up how to find a standard deviation
Answer:
40
Step-by-step explanation:
0.13 ⟌5.2 (We can move 0.13 over two spots)
13⟌520 (We move the decimal two spots because of previous)
We have
₄ ₀
13⟌520
- 52
______
0 0
- 0
______
0
So 40 is our final answer.
(u/v)(x) =
x^2 - x^4 + x^2
---------------------- = - (1 - x^2 + 1) = - (2 - x^2).
-x^2
I'd suggest you double check to ensure that you've copied down this problem correctly.
Answer:
b. (√15)/4
Step-by-step explanation:
Since Sin Ф = (opposite side)/Hypotenuse, we have 2 sides of a right triangle.
Use Pythagorean theorem to solve for the missing leg (the adjacent side)
1² + b² = 4²
1 + b² = 16
b² = 15
b = √15
So the adjacent side is √15, so Cos Ф = (√15)/4
Answer:
C. (x + 8) (x + 7)
Step-by-step explanation:
<em><u>To factor this trinomial, you must split the middle term (15x) into two terms that can be added to get 15x, and multiplied to get 56:</u></em>
<em><u /></em>

<em><u>Group:</u></em>
<em><u /></em>
<em><u>Take out the GCF (Greatest Common Factor):</u></em>
x(x + 7) 8(x + 7)
(x + 8) (x + 7)
