8 is 91 because 13•7 is 91 inside is needed 91 tiles
Answer:
228
Step-by-step explanation:
Answer:
y=x, x-axis, y=x, y-axis
Explanation:
Reflecting the figure across three axes just moves it from one quadrant to another. It does not map the figure to itself.
Reflecting across the line y=x moves it from quadrant II to IV or vice-versa. If it is in quadrant I or III, it stays there. So the sequence of reflections x-axis (moves from I to IV), y=x (moves from IV to II), x-axis (moves from II to III), y=x (stays in III) will not map the figure to itself.
However, the last selection will map the figure to itself. The initial (and final) figure location, and the intermediate reflections are shown in the attached. The figure starts and ends as blue, is reflected across y=x to green, across x-axis to orange, across y=x to red, and finally across y-axis to blue again.
We can solve this by converting both measurements to inches.
Orange tree:
1 foot=12 inches
7 feet=84 inches
84 inches + 9 inches = 93 inches total
Lemon tree:
1 yard=3 feet=36 inches
2 feet=24 inches
36 inches + 24 inches + 5 inches=65 inches total
Therefore, the orange tree is taller than the lemon tree.
Answer:
The parametric hypothesis tests that we introduced in Chapter 5 were all based upon the means of the sample and population.
