Answer:
A
Step-by-step explanation:
Answer:
(-3a+-2x)(2a+-1x)=0
Step-by-step explanation:
Simplifying
x2 + -1ax + -6a2 = 0
Reorder the terms:
-1ax + -6a2 + x2 = 0
Solving
-1ax + -6a2 + x2 = 0
Solving for variable 'a'.
Factor a trinomial.
(-2a + -1x)(3a + -1x) = 0
The probability is 0.336.
To solve this, we need Binomial Probability equation for Repeated Trials.
P = nCr (p)^r (q)^(n-r)
where P = probability (unknown)
n = number of trials (8)
r = number of successes (1)
p = probability of success (.20)
q = probability of failure (0.80)
P = 8C1 (.20)^1 (.80)^7
= 0.336
When a shape is rotated about its centre, if it comes to rest in a position and looks exactly like the original, then it has rotational<span> symmetry. </span>rotational<span> symmetry</span>order). This means that a regular hexagon has 6 sides, 6 lines of symmetry and anorder<span> of </span>rotational<span> symmetry of 6.</span>
20km
15km 3/4
_____ = ___
Xkm 4/4
cross multiply...
3/4x=15
divide both sides by 3/4
x=20km
