P=2(l + b)
P=2l + 2b
P-2b=2l
P-2b/2=l
C is your answer
I got.......6x^3 + 5x^2 - 3x - 2................not sure though
Answer:
The probability of finding the entry in the period between 30 and 32 minutes is 5%.
Step-by-step explanation:
Given that the time required to find an entry is uniformly distributed between 0 and 60 minutes, it implies that 100% of the chances are in that period of time distributed equally. Therefore, since 100/60 is equal to 1.66, each minute has a 1.66% chance that the entry will be there.
Thus, since between minutes 30 and 32 there are 3 minutes in total (30, 31 and 32), to determine the probabilities of finding the entry in that period it is necessary to perform the following calculation:
1.66 x 3 = X
5 = X
Therefore, the probability of finding the entry in the period between 30 and 32 minutes is 5%.
Answer:
30 yd²
Step-by-step explanation:
Hello There!
The shown figure is a trapezoid
The first thing we need to do is figure out what the formula for area of a trapezoid is
where a and b = bases and h = height
we are given all of the dimensions so all we have to do is plug in the values
a = 9
b = 6
h = 4
so we can conclude that the area of the figure is
30 yd²
