This is a perfect example of exponential decay. In this case the growth factor should be represented by a fraction, and it is! This forest, starting out with apparently ( 800? ) pine trees, has a disease spreading, which kills 1 / 4th of each of the pine trees yearly. Therefore, the pine trees remaining should be 3 / 4.
Respectively 3 / 4 should be the growth factor, starting with 800 pine trees - the start value. This can be represented as such,
- where a = start value, b = growth factor, t = time ( <em>variable quantity</em> )
____
Thus, the function can model this problem. The forest after t years should have P( t ) number of pine trees remaining.
x3 × x3 × x3 (I'm assuming you mean 3x for that) is equal to 9x^3. x3 × 3 × 3 is equal to 9x. They are not equivalent because one expression has 3x, 3 times, because you are multiplying the 3's together, and adding the x's three times, you get 9x^3. The x's are important since it differentiates between both expressions. 3x × 3 × 3, there is only one x in it, so it is just 9x. Does 9x=9x^3? No.
1 yard= 36 inches
10 yards* 36= 360 inches.
360 inches= 360 inches
So, 10 yards and 360 inches are equal.
Answer:
If the differences between <u>the group means is large relative to the amount of variability in the scores</u>, the group differences are probably significant. If, however, there is a lot of variability in the scores, then the difference between (or among) the group means will not seem so large, a non-significant difference.
So to summarize, it depends on the group. As there is no shown group, I can't determine what it would be.
