Question One
The first question is just to derive a formula that represents the cost of anything bought in Idaho.
c = p + 6/100 * p
c = p + 0.6 * p
c = 1.06 p
Question Two
The second question requires an entirely different formula. You don't use the first formula. You just use it's idea. Further, you take the sales tax only when you know how much money has exchanged hands.
c = (p - 30/100 p) + 6/100*(p - 30/100 * p)
c = (p - 0.3p) + 0.06* (p - 0.3p)
c = 0.7 p + 0.06*(0.7p) Combine the right side
c = 0.7p + 0.042p Combine
c = 0.742p
33.39 = 0.742p Divide by 0.742
33.39/0,742 = p
p = 45 dollars
The original cost was 45 dollars
Answer:
Probability = 0.0073
probability = 0.000007122
Step-by-step explanation:
given data
drawing = 10 cards
ordinary -card pack = 52 pack
solution
we know that here drawings done with replacement so that there is Probability that not 2 card of the same denomination
so
Probability = Probability of selecting a card × Probability of selecting a card not of the first denomination × Probability of drawing a card not from 2 denominations and continuous so on .......
so
Probability = 1 ×
... .... .... .... ... ...
Probability = 0.0073
and
when cards is drawn without replacement
probability = probability that exactly 9 of same suit and 10th of a different suit + Probability all 10 are of same suit
so
probability =
probability = 0.000007122
Answer:
x = 1
Step-by-step explanation:
7x - 3 = 4x
-3 = 4x - 7x
-3 = -3x
x = 1
