Step-by-step explanation:
5x+2y=-11
2x+2y=5
so you find values that match or can multiply by something to match-2
5x+2y=-11
- 2x+2y=5
=3x+0y=-16
3x/3=-16/3
x=5 1/3
then substitute x in one of the equations to get y
Answer:
Step-by-step explanation:
The graph of g(x) would be the same as that of f(x) EXCEPT that the graph of g(x) would be translated h units to the left. For example, if you had f(x-[-5]), the graph of f(x) would be translated 5 units to the left.
Answer:
a. Mean = 155.1 grams
b. Standard deviation = 0.37
c. Fractional uncertainty = 0.074
Step-by-step explanation:
a. Average weight
This is same as the mean weight;
Mathematically, that would be; sum of the weights/ the number of weights
= (155.1 + 154.8 + 155.5 + 155.3 + 154.6)/5 = 775.3/5 = 155.06 which is approximately 155.1
b. Standard deviation
Mathematically; we calculate that using the formula;
√{(x-mean)^2/(N-1)}
Please check attachment for for the complete breakdown of this
c. Fractional uncertainty
= Standard deviation/number of measurements = 0.37/5 = 0.074
Answer:
C. ED
Step-by-step explanation:
The center of the angle is the point E, so it would be written first.
B 2/10 is not simplified because you can divide each number by 2 reducing it to 1/5.
