Answer:
≈419.4 cm.
Step-by-step explanation:
To solve this problem, you will need to set up an exponential graph as shown:
y= 40 ·
The 40 represents the initial height of the tree, while (1.6) represents the annual growth rate. 'x' represents the amount of years elapsed.
We can simply solve this by substituting 5 for x:
y= 40·
y ≈ 419.4 cm.
This problem is very difficult to imagine without the figure. However I dug up on other sources and I think I found the correct figure to work with (see the attached pic).
We can see that in the figure, the hexagon is inscribing the pentagon. What is meant here to be lines of reflection simply means lines of symmetry. If we take on the hexagon alone, there are a lot of lines of symmetry. We can create the line intersecting E & B and the figure would still be symmetrical on both sides or D & A, F & C and etc. So there are a lot for hexagon alone.
However in this case, our lines of symmetry is made limited by the presence of the pentagon. If we slice the pentagon into two, the only line of symmetry we could create would be the line intersecting O and the median of LM. Other lines would not create a symmetrical half.
Therefore the line of reflection is only <u>1.</u>
Considering the situation described, the null hypothesis is given as follows:
.
At the null hypothesis, it is tested if the <u>mean is the same as in the Census</u>, of $64,000, hence:
.
At the alternative hypothesis, it is tested if the mean is different from the Census, hence:
.
