Answer:
x=4
Step-by-step explanation:
-5x+5-x+1=-18
combine like terms
-6x+6=-18
subtract 6 from both sides
-6x=-24
divide both sides by -6
x=4
You know, if you check your calculator, it has a [ ₙPᵣ ] and also an [ ₙCᵣ ] button, and you could use that, now, if you want the factorial version,
Answer:
The distribution positively skewed
Step-by-step explanation:
We have the mean of a distribution to be 276, while the median is 231.
When compare the mean and median,
we gave
276>231
Since the mean is greater than the median, the distribution is skewed to the right.
In other words, the the distribution is positively skewed.
Let x = length of the park
Let y = width of the park
Because the area is 392392 ft², therefore
xy = 392392 (1)
Because three sides of fencing measure 5656 ft, therefore
2x + y = 5656 (2)
That is
y = 5656 - 2x (3)
Substitute (3) into (1).
x(5656 - 2x) = 392392
5656x - 2x² = 392392
2x² -5656x + 392392 = 0
x² - 2828x + 196196 = 0
Solve with the quadratic formula.
x = (1/2)*[2828 +/- √(2828² - 4*196196)]
= 2756.83 or 71.17
Answer:
The possible dimensions are 2756.8 ft and 71.2 ft (nearest tenth)
