1) Striangle = 1/2 * (12-8) * 4 = 1/2 * 4 * 4 = 8 km^2
2) Srectangle = 4 * 8 = 32 km^2
3) Sfigure = 8 + 32 = 40 km^2
Number C
Answer:
1/15
Step-by-step explanation:
2/5-1/3=6/15-5/15=1/15
The equation of the least-squared regression line is: In(Element) = 2.305 - 0.101(Time).
<h3>What is a regression line?</h3>
A regression line displays the connection between scattered data points in any set. It shows the relation between the dependent y variable and independent x variables when there is a linear pattern.
According to the given problem,
From the table we can see,
ln(Element) is the dependent variable and Time is the independent variable.
The constant = 2.305,
Time = -0.101
Hence, we can conclude, our least squared regression line will be
In (Element) = 2.305 - 0.101 (Time).

You can complete this by solving:
Which should give you .274418 or 27.44%
Answer:
396
Step-by-step explanation:
it's it's 396 because if you add 99 more you will get 495.
each percentage is 99, so 99 x 5 is how many students there are 99 x 4 is the answer.
