Answer:
A=x^2-16x+64=
x^2-2*8x+8^2=
(x-8)^2=l^2
so l= x-8
Step-by-step explanation:
Answer: A. the external conflict of character versus character
Step-by-step explanation:
Hi, in this excerpt we can see a external conflict of character versus character between Buck and Spitz.
Spitz is a Lead dog with a determination to maintain that role. But Buck, also wants the leadership, and is not afraid to fight for it.
Buck has a desire for mastery, that desire generates a conflict between the two, for the leadership of the pack.
With one single year of records, we do not have a reliable way to choose the place with a warmer mean temperature, given that the median temperatures are close.
The choice of the answers depend a lot on the justifications.
first answer: the justification (Orlando has a higher IQR) is incorrect, so eliminated.
second answer: the justification is based on the premise that mean is usually close to the median, given symmetric distributions. Since both distributions are not too skewed, this option could be retained.
third answer: higher maximum temperature with a lower median could mean that it is a once in a while occurrence, and may not generalize.
fourth answer: the justification is not unreasonable, with a greater IQR in Tempa Bay, and the mean of Q1 and Q3 (68) is higher than the median temperature of Orlando, there is a chance that its mean temperature (last year) is higher.
All in all, I personally believe Orlando is a better bet because the justifications "higher median and smaller IQR" (opt.2) are more concrete and more convincing than the "chance" (opt. 4) that the mean is higher in Tempa Bay.
Vivian problem: If her highest score is 42 points higher than her lowest score, just subtract 42 from 438. The answer is 396.
Concert problem: let w=women and 2w=men. your equation would be: w+2w=714
3w=714
w=238. There were 238 women.
Park problem: let the length=3w and the width=w. so, to find w, you would have to divide by 3, and since the length is 123, do (your equation would be 3w=123) 123/3 which would give you 41 ft for the width.
Darwin's age: let darwin's age=2f+6 and fiona=f. If darwin's age=50, then set 2f+6=50
2f=44
f=22. Fiona's age is 22 years.
