The chance that any given bulb is on is equal to 1/2. The chance that all twenty bulbs are on at the same time is
Answer:
35-=13 boxes ; 65-9 boxes
Step-by-step explanation:
35 x X+ 65 (22-x)=1040
35x+1430-65x=1040
1430-30x=1040
30x=390
x =390/30=13
Answer:
7/10
Step-by-step explanation:
67/10-60/10=7/10
Answer:
Y=1/3
Step-by-step explanation:
X=k/y
So let's make k the subject of formula
k=xy
x=1,y=5
So let's substitute
k=1×5
k=5
So we are to determine the value for y when x is 15
So let's solve
Y=k/x
Y=5/15
Y=1/3
Y=0.333333~0.3
F(2) means that you are plugging in 2 for x, while f(x)=2 means that the equation equals 2 (y=2) at a certain x value.
