Answer:
P(A) = 3/20
Step-by-step explanation:
P(A)=P(blue)P(head)=(3/10)(1/2)=3/20
as there are 10 cards in total, out of which 3 are blue so the probability to get the blue card is, P(blue) = 3/10. and the probability of getting a head when a coin is tossed is P(head) = 1/2.
So in total
P(A) = P(blue)*p(head) = (3/10)*(1/2) = 3/20 = 0.15
Answer:
y=12
Step-by-step explanation:
y=2x ,so 2x=8x-x^2
x^2=8x-2x
x^2=6x
x^2/x=6x/x
x=6
y=2x ,2(6)
y=12
Answer:
$18360
Step-by-step explanation:
Since, the value decreased by 40%, the price is (100-40)% of 34000
= 60% of 34000
= 60/100 * 34000
= 60 * 340
= 20400 --- (Price after first year)
Since, the value decreased by 10%, the price (100-10)% of 20400
= 90% of 20400
= 90/100 * 20400
= 90 * 204
= $18360
