Answer:
50 pockets
Step-by-step explanation:
Total yards of lace = 75
Yards to decorate one Pocket = 1 1/2 yards
How many pockets can she decorate with the lace
Number of pockets she can decorate with the lace = Total yards of lace / Yards to decorate one Pocket
= 75 ÷ 1 1/2
= 75 ÷ 3/2
= 75 × 2/3
= 150/3
= 50
Number of pockets she can decorate with the lace = 50 pockets
Answer: 0.4
-----------------------------------------
Explanation:
P(q) = 0.2
P(r) = unknown
P(q and r) = 0.08
Since events q and r are independent, this means we can use the formula
P(q and r) = P(q)*P(r)
Plug in the given info and isolate P(r)
P(q and r) = P(q)*P(r)
0.08 = 0.2*P(r)
0.2*P(r) = 0.08
P(r) = 0.08/0.2 <<-- divide both sides by 0.2
P(r) = 0.4

1
the only number it can be is 1 as 1 + 
( the reciprocal of 1 )
thus 1 + = 2
