B,
P(A and B)= P(A)xP(B)
P(A and B)=0.60x0.30
P(A and B)=0.18
False because you must know all of its components in order to solve the equation
Answer:
-10d⁴ + 17d²s - 6s²
Step-by-step explanation:
Multiply using FOIL
First
-2d² * 5d² = -10d⁴
Outer
-2d² * -6s = 12d²s
Inner
s * 5d² = 5d²s
Last
s * -6s = -6s²
-------------------------
Together
-10d⁴ + 12d²s + 5d²s - 6s²
Combine like terms
-10d⁴ + 17d²s - 6s²
Answer:
Step-by-step explanation:
X^2 -6x +1 = 0
a=1
b = -6
c = 1
Use the quadratic formula
x = [-b +- sq root (b^2 -4ac)] / 2a
x = [--6 +- sq root (36 - 4)] / 2
x = [ 6 +- sq root (32)] / 2
sq root (32) = 5.657
x1 = [ 6 + 5.657] / 2
x1 = 11.657 / 2
x1 =
<span>
<span>
<span>
5.8285
</span>
</span>
</span>
x1 = 5.82 (to nearest tenth)
x2 = [ 6 - 5.657] / 2
x2 = .343 / 2
x2 = .1715
x2 = .2 (to nearest tenth)
