Answer:
60%
Step-by-step explanation:
Total Cards = 5
Even Numbers = 3
P(even) = 3/5
<u><em>In %age:</em></u>
=> 60%
Taking the Dot Product = 0 shows perpendicular or orthagonal vectors.
Then 2ax6 -axa +32x(-1) = 0
a^2 -12A +32 = 0
(a-8)(a-4) = 0
a = 4,8
Answer:
1.8 years
Step-by-step explanation:
Step one:
given data
P= $2000
Rate= 5%
Final amount A= $3800
Step two
A= P(1+rt)
substitute
3800=2000(1+0.05*t)
solve for t
3800=2000(1.05t)
3800=2100t
divide both sides by 2100
t= 3800/2100
t=1.8 years
it will take 1.8 years
