(2−2n)−(5n−27) >0
distribute
2-2n -5n +27 >0
combine like terms
-7n +29 >0
subtract 29 from each side
-7n> -29
divide by -7 (flips the inequality)
n < -29/-7
n <4.14
natural numbers are 1,2,3,4......
n must be 1,2,3,4
Answer: 1,2,3,4

Answer:
40% reduction
Step-by-step explanation:
To answert this, we need to find how much of the price is each percentage. This can be found my subtracting the percent from 100:
Sale price: 100 - 20 = 80
Last day price: 100 - 25 = 75
Now we need to multiply these two values together, remembering to divide both numbers by 100 first:
80 ÷ 100 = 0.8
75 ÷ 100 = 0.75
0.8 * 0.75 = 0.6
Then multiply by 100 to find the percentage:
0.6 * 100 = 60
60% is the end price, but to find the overall reduction we need to subtract this value from 100:
100 - 60 = 40
So there was a 40% reduction on the price.
<h2>Hope this helps!</h2>

Answer:
a. P) = 0.25
b. P) = 0.25
c. P) = 0.5
Step-by-step explanation:
a) 1/4 as 1/2 x 1/2 = 1/4 = 0.25 This becomes reduced as we are multiplying one complete probability journey by another complete probability journey.
b) see above as 1/2 x 1/4 and 1/4 x 1/2 = 2.5 = 1/4 = 0.25
or we can Set to 1 and 1 - 3/4 = 1/4. = 0.25.
c) 1/2 as half of the journeys have traffic jams so its 1 - 1/2 = 1/2 = 0.5
