If the yodeler is at 5800 ft above sea level.....and he descends 200 ft....he will then be at (5800 - 200) = 5600 ft above sea level where he meets his friend
Answer:
a) True
Step-by-step explanation:
The given statement is true.
where 
are data points, 
is the mean and n is the number of observations.
The standard deviation express the variation of data from the mean and therefore, have the same unit as the data like lbs, inches, dollars, etc.
Coefficient of variation on the other hand is the ratio of standard deviation and mean. It is also a measure of dispersion but since it is a ratio, the units cancel each other.
Thus, coefficient of variation is dimensionless.
Thus, it is a relative measure.
Answer:
143 calories
Step-by-step explanation:
We can use a ratio to solve
110 calories x calories
----------------- = ---------------
28.4 grams 36.92 grams
Using cross products
110* 36.92 = 28.4 * x
Divide each side by 28.4
110*36.92 / 28.4 = x
143 calories = x
Step-by-step explanation:
a=2
b=-7
c=-15
-(-7)+-sq root (-7)²-4(2)(-15) / 2(2)
7 +- sq root 169 / 4
7+- 13 / 4
7+13 / 4, 7-13 / 4
x=5 x=-3/2
So slope intercept form is y=mx+b.
So the equation of the line is:
y= -4x - 3
Hope this help!
