Answer:
6%
Step-by-step explanation:
60 = 500•2•rate
60 = 1000•rate
rate = 60/1000
rate = 0.06 = 6%

(x-10)*(x-3)
Therefore the roots are:
X = 10
X = 3
Answer:
1/2 ; 1/4
Step-by-step explanation:
Number of cards in a deck = 52
Number of red cards = 26
Number of spades = 13
Probability of event A :
P(A) = required outcome / Total possible outcomes
P( red card) = number of red cards / total cards in deck
P(red card) = 26 / 52 = 1/2
P(spade) = number of spades / total cards in deck
P(red card) = 13 / 52 = 1 / 4
