Given :
The probability of someone having a reaction to a medication is 0.025 .
To Find :
The probability of two out of tree people having a reaction.
Solution :
Let, P is the probability of two out of tree people having a reaction.
So, P = ( first had reaction ) × ( second had reaction ) × ( third do not had reaction )
P = 0.025 × 0.025 × ( 1 - 0.025 )
P = 0.00061
Hence, this is the required solution.
Answer:
Seats increase by 4 each time a table is added.
Seats = 4 x #ofTables
Step-by-step explanation:
You have 6 seats with one table
You have 10 seats with two
14 with three
If you try out five, there will be 18 seats
6-10-14-18

Let the exterior angle be y.
We know that the exterior angle is the sum of opposite two interior angles.
Therefore, y = 3x + 90 --- (1)
Also, y and 5x - 6 are linear pair.
Therefore, y + (5x - 6) = 180
Substituting y = 3x + 90 from (1), we get,
(3x + 90) + (5x - 6) = 180
8x + 84 = 180
8x = 180 - 84 = 96
x = 12 degrees
Hence, exterior angle y = 3(12) + 90 = 126 degrees.
Answer:
.35 x + .70 (20) = .45(x+20)
50=x
Step-by-step explanation:
Let x = liters of 35% salt solution
We have 20 liters of 70%
We have a total of 20+x liters of 45%
.35 x + .70 (20) = .45(x+20)
Distribute
.35x + 14 = .45x +9
Subtract .35x from each side
14 = .10x +9
Subtract 9 from each side
5 = .10x
Divide each side by .1
5/.1 = x
50=x
