Answer:
The probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur = 0.375
Step-by-step explanation:
The probability of event A occurring = 50% = 0.5
The probability of event B occurring = 25% = 0.25
Events A and B are non simultaneous events.
The probability of event B does not occur = 1 - P(B)
= 1- 0.25
= 0.75
So the probability of event A occurs but event B does not occur = P(A)* Probability of event B does not occur
= 0.5*0.75
= 0.375

Ratio of 1:3:5
Sum= 1+3+5 = 9 total parts
dividing 72kg
For 1: = 1/9 * 72 = 8kg
For 3: = 3/9 * 72 = 24kg
For 5: = 5/9 * 72 = 40kg
One set of magnet with 10% discount would cost
(6.4)*(1-0.10) =
6.4*0.9 = 5.76
For two sets of magnets
5.76*2 =11.52
Answer:
- 39
Step-by-step explanation:
x + 7= (-2)^5
x + 7 = -32
x = - 32- 7
x = - 39
x + 2
