The answer is C . -7r^2 + 12r -8
If you are asked to find the 85th percentile, you are being asked to find a data value associated with an area of 0.85 to its left.
Percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall. For example, the 30 th percentile is the value below which 20% of the observations may be found.
You plug in the values for x in each respective equation.
a) f(3) = 3 + 1 which equals: 4.
so, f(3) = 4
b) g(3) = (3)^2 - 3 which equals 9 - 3, which equals 6.
so, g(3) = 6.
hope this helps! (:
Answer:
ED = 12 and FD = 24
Step-by-step explanation:
See the attached diagram.
The perpendicular distance between the three parallel lines are same i.e. AB = BC = 8
Therefore, the parallel lines will divide any transverse line ( say FD ) in 1 : 1 ratio i.e. will divide equally.
Therefore, FE = ED = 12 units.
Again, FD = FE + ED = 12 + 12 = 24 units. (Answer)
What makes no sense I don't get it what it means plus look it up if can
