Answer:
a)
Step-by-step explanation:
x is always the rate of change.
And the initial value is the number after the x. In this case it's 1
The sale price is $ 10.35
10% of 11.5 is 1.15
(10/100 = x/11.5)
11.5-1.15 = 10.35!
4 nickels=4*0.05=0.20
3 dimes=3*0.10=0.30
2 quarters=0.50
total= 1.00

Answer:
1/1000
Step-by-step explanation:
The probability of two independent events A, B (independent = events that do not depend on each other) is given by the product of the individual probabilities of A and B:
(1)
In this problem, the single event is "getting a 3" when extracting a random number between 1 and 10.
The total number of possible outcomes is
n = 10
While the number of succesfull outcomes (getting a 3) is only one:
So, the probability of drawing a 3 in 1 draw is
Then, we want to find the probability of getting three "3" in 3 consecutive generations. These events are independent events, so we can use rule (1) to find the total probability, and we get:
4 3/8 x 2 = 8 6/8
4 3/8 divide 2 = 3/32
6/8 x 4 = 24/32
24/32 + 3/32 = 27/32
