Answer:
A reduction of 64.3 percent
Step-by-step explanation:
Initial price of Brent crude oil=$140 per barrel
Final price of Brent crude oil=$50 per barrel
The percentage change in price=((Final price-Initial price)/(Initial price))×100
(50-140)/140=-0.6429×100=-64.29
Rounding off to tenth of a percent=10/100=0.1
-64.29=-64.3 since 64.29 is nearer to 64.3 than 64.2
-64.3 percent implies a reduction of 64.3 percent
There was a reduction of 64.3 percent
Answer:
Step-by-step explanation:
It would be easier to just show you.
Because we're using variables, I'm going to plug in a random set of numbers to stand for x and y.
(x+y)^2
(2+4)^2=36
vs.
x^2+y^2
2^2+4^2=20
The difference is because, following the order of operations, in the first situation you must first take care of what is in the parenthesis, which means you add x and y together-then you multiply that combined number by the 2nd power. Whereas in the second situation, you multiply x and y by the 2nd power separately, and then add the product of that together. So opposite order. In the first situation you add, then multiply. In the second, you multiply then add.
I believe it’s mean because you want the average
