Answer:

Step-by-step explanation:

You have ONE equation here in TWO unkowns.  You can solve for either x or y but not both.  Only if you have a system of TWO equations can you find the values of x and y that satisfy both equations.

-2x - 4 + 5y = 8 is to be solved for y:

Add 4 to both sides to combine the constant terms:

-2x + 5y = 12

To solve for y, add 2x to both sides, obtaining:

5y = 2x + 12

and then divide all three terms by 5:

y = (2/5)x + 12/5

-2x - 4 + 5y = 8 can also be solved for x if desired.

This lesson asked you to investigate what it means for data to fall within 1, 2, and 3 standard deviations from the mean in a va
s2008m [1.1K]

Answer:

The data in statistics is generally supposed to deviate or vary from the mean. Standard deviations of 1, 2, and 3 are commonly used to calculate variability according to the empirical norm. In a normal distribution, we estimate 68 percent, 95 percent, and 98 percent of the data to be within 1, 2, and 3 standard deviations of the mean, respectively. This implies that the given percentage of data will lie within an interval of less than or greater than the standard deviation. If the values within a given standard deviation from the mean are standardized, the z value will always be equal to or less than the given standard deviation.

We should look at a program that aims to help people get out of poverty by using the standard deviation principle. The aim of the program is to provide free seeds to poor people who have been suffering from low yields due to the use of local seeds. If we use the definition of one standard deviation of the mean, or 2 and 3, we will favor the majority of people, but we will leave the poorest people in society behind.
