Answer:
No Solution
Step-by-step explanation:
If xy = 1, and y is 0, then you can plug in 0 for y. x(0) = 1. You would then need to divide by 0 on both sides, but you cannot do that. Therefore, there is no soultion.
M a t h w a y to find the answer
Start by dividing both sides by 2 to get

. Doing the math on the right, keeping in mind that logs have an unwritten base of 10, gives us

. Rewriting this in exponential form is

. That means that x = 8. Not negative, only positive.
Answer:10
Step-by-step explanation:
Answer:
a) 60
b) 0.24
c) 150
Step-by-step explanation:
a) P(green) = ⅕
Expected no. = 300 × ⅕
= 60
b) total = 300
P(purple) = 72/300
= 6/25 = 0.24
c) P(blue) = 45/300
= 3/20 = 0.15
Expected no.: 1000 × 0.15
= 150
