Answer: x = 1.28 or -1.28
7/10 m= 0.7 m
4.1÷0.7=5.85
You would round down 5.85 to just 5, because he cannot cut less than a whole strip.
To find the exact amount of wire used in 5 strips:
5×0.7= 3.5
4.1-3.5= 0.6 m will be leftover.
Answer:
Proved,
P(A∪B)=0.72
Step-by-step explanation:
Sue travels by bus or walks when she visits the shops.
Probability( catch the bus to the shop ), P(A) = 0.4
Probability( catch the bus from the shop ), P(B) = 0.7
Both A and B are independent events.
Therefore,
P(A∩B) = 0.4×0.7
= 0.28
Probability Sue walks one way = 1 - P(A∩B)
= 1 - 0.28
= 0.72
Hence, the probability that Sue walks at one way is 0.72
