Answer:
I am sorry i cant help you if you dont have a picture.
5x + 2y = 6
3x + y = 4....multiply by -2
-------------
5x + 2y = 6
-6x - 2y = -8 (result of multiplying by -2)
-------------add
-x = -2
x = 2
5x + 2y = 6
5(2) + 2y = 6
10 + 2y = 6
2y = 6 - 10
2y = -4
y = -4/2
y = -2 <=== here it is
Answer: the answer is 6.876
To answer this question, you must know what the standard deviation is.
The standard deviation is an index that measures the dispersion of a data set, while the largest is the standard deviation most dispersed are the data with respect to the mean value.
For a normal distribution, it is known that 68% of the data is not more than one standard desviation of the mean.
In this case, when they talk about -1 standard deviation of the mean.
Is:
average - 1 standard deviation
So
62 - 5.7 = 56.3
Therefore, the value sought is 56.3
