according to the formula 21.9-0.3 X the year in which the percentage of Americans who are in high school dropout would be 6.5 is approximately.
The year is approximately 2020.
HEEEEEEELLLLLLPPPPPPPPP
It would help if you stated a proper question.
What does 21.9 - 0.3 X represent?
What does X represent?
Of course the bot's answer is as meaningless as the question.
To find the year in which the percentage of Americans who are high school dropouts would be approximately 6.5 according to the given formula, you need to solve the equation 21.9 - 0.3X = 6.5. Here's how you can do that:
1. Start with the equation: 21.9 - 0.3X = 6.5.
2. Subtract 21.9 from both sides of the equation to isolate the term with X: -0.3X = 6.5 - 21.9.
3. Simplify the right side of the equation: -0.3X = -15.4.
4. Divide both sides of the equation by -0.3 to solve for X: X = -15.4 / -0.3.
5. Calculate the value of X: X ≈ 51.33.
Therefore, the year in which the percentage of Americans who are high school dropouts would be approximately 6.5 is 51.33. Please note that in this context, the year is represented as a decimal because the formula uses X as a continuous variable.
