In this you could say 2.5L and 3.5L for total 6L. minus the 5L drunk and get about a liter left. in actuality:
x = 2.45 + 3.65 - 4.85 = 1.25
I would say that the estimation was reasonable.
in probability, it is equally as likely that a decimal lies between x and x.5 as it is for it to lie between x.5 and x+1. therefore when given a few numbers the rounding effect would likely round overall the same amount of points down as up. this would make it likely that the estimation would have on my an error within the amount rounded to. as you can see I rounded to 0.5 and the answer was half that
Answer:
x=-5/8, y=15/2, z=-10. (-5/8, 15/2, -10).
Step-by-step explanation:
4x-7y=5
8x+3z=-35
6y+3z=15
----------------
4x=7y+5
2(4x)=2(7y+5)
8x=14y+10
14y+10+3z=-35
14y+3z=-35-10
14y+3z=-45
-----------------------
14y+3z=-45
6y+3z=15
------------------
14y+3z=-45
-(6y+3z)=-15
---------------------
14y+3z=-45
-6y-3z=-15
--------------------
8y=-60
simplify,
y=15/2
6(15/2)+3z=15
45+3z=15
3z=15-45
3z=-30
z=-30/3
z=-10
8x+3(-10)=-35
8x-30=-35
8x=-35+30
8x=-5
x=-5/8
x=-5/8, y=15/2, z=-10.
The answer would be C) 24,500.
Tan(x)= 33/105
x = arctan(33/105)
x = 17.44718842 degrees.
Option B (22,16,18,36)
Mean- Mean is an average of the data collected in the data set. It can be found by dividing the sum of the values by the number of values. Median is the middle value of the data set when the values are placed in order from least to greatest.
It is easy to calculate: add up all the numbers, then divide by how many numbers there are.
Add all the numbers (22+16+18+36) = 92
Avarage = sum of the all given numbers/ total numbers
total numbers =4
so avarage= mean= 92/4 =23
(22,16,18,36) has the most spread because one number as low as 16 and one as high as 36. Our mean is 23, so that means that the spread is huge.
Hence the answer is (22,16,18,36).
