10) What is the value of this prefix expression when read as an
infix expression? Draw the ordered rooted tree corresponding to the
below arithmetic expressions written in prefix notation.
a) x,/,9,3,+,x,2,4,-,7,6
b) -,x,2,/,8,4,3
c) 5,2,1,-,-,3,1,4,+,+,x
d) 9,3,/,5,+,7,2,-,x
a = [-5, -3, 2] b = [1, -7, 9] c = [7, -2, -3] d...
a = [-5, -3, 2] b = [1, -7, 9] c = [7, -2, -3] d = [4, -1, -9,
-3] e = [-2, -7, 5, -3]
a. Find (d) (e)
b. Find (3a) (7c)
c. Find Pe --> d
d. Find Pc --> a +2b
ex. C = |x|(xy/xy) C = xy/|x|
ex. P x --> y = Cux = C(xy/x) (1/|x|) (x) =( xy/yy)(y)

Consider the following population: {7, 8, 8, 9, 9}. The value of
μ is 8.2, but suppose that this is not known to an
investigator. Three possible statistics for estimating μ
are
Statistic 1: the sample mean, x
Statistic 2: the sample median
Statistic 3: the average of the largest and the smallest values
in the sample
A random sample of size 3 will be selected without replacement.
Provided that we disregard the order in which the observations are
selected,...

1. Use the given conditions to find the exact value of the
expression.
sin(α) = -5/3, tan(α) > 0, sin(α - 5π/3)
2. Use the given conditions to find the exact value of the
expression.
cos α = 24/25, sin α < 0, cos(α + π/6)
3. Use the given conditions to find the exact value of the
expression.
cot x = √3, cos x < 0, tan(x + π/6)
4. If α and β are acute angles such that...
