Answer:
y=4
Step-by-step explanation:
first you that the number outside of the parenthesis and multiply it by the numbers inside 3x3y (ignore the y for right now) and 6x3 now we have 9y-18=18 now we move the 18 so the y is by itself now we have 9y=36 divide both by 9 and you get your answer y=4
Answer:
Option B.
Step-by-step explanation:
The non-uniform probability is when the event is not same in the occurring of event.
Option A is uniform because there will be equal chance of getting head or tail.
Option B is non-uniform because sum can be any number if we get(3,4) it will be 7 and if we have (2,3) then it will be 5.
Option C is uniform because we have equal number of red and green balls so, selecting a ball from both will be same.
Option D is uniform because chance of 1,2,,3,4,5 or 6 will be equal chance from rolling a die that is 1/6 in all cases.
Therefore, Option B is correct
Answer:
10=16[ by cost]
Step-by-step explanation: the cost of 10 chairs is x.
the cost 16 chairs is also x. 10x = 16x
4x is loss.
Profit or Gain = Selling price – Cost price. Loss = Cost price – Selling price. Profit Percentage = [Profit/C.P.]×100. Percentage Loss = [Loss/C.P.]×100.
In simple way, we can say that sp- cp[ when it is a gain], cp -sp[ when it is a loss]. here it is a loss as well as a gain. so do both according to the formula
