The regression equation of the data values is y = 0.3x^2 - 2.8x +4.2
<h3>How to determine the regression equation?</h3>
Using a technology such as a graphing calculator, we simply input the data values in the graphing calculator and then wait for the result.
The x coordinates must be entered into the x values and the y coordinates must be entered into the y values
Using a graphing technology, the regression equation of the data values is y = 0.3x^2 - 2.8x +4.2

The formula for the law of cosines is:
a^2 = b^2 + c^2 - 2*b*c*cos(angle)
In this triangle b = 7, c = 8 and angle = 32.
a^2 = 7^2 + 8^2 - 2*7*8*cos(32)
a^2 = 18.018
a = SQRT(18.018)
a = 4.24
C = 4.2 feet.
The standard form is 24,000,011
Answer: 3/2
Step by step:
3/4 + 4y/3
3/4 + 4y/3 = 4y/3 + 3/4
y= 1 1/2 = 3/2
Answer:
20 * 10⁻⁹
Explanation:
Assume that the number of times is t
Now, we want to know what number (t) multiplied by 2 * 10¹⁴ will result in
4 * 10⁶
Translating this into an equation:
2 * 10¹⁴ * t = 4 * 10⁶
Solving for t:
t = (4 * 10⁶) / (2 * 10¹⁴)
t = 20 * 10⁻⁹
Hope this helps :)
