A ur welcome :D hope im helping:D
Answer:
for level 1: x=36
because you just need to do 180-144
for level 2: x = 127
you can just so 180-15-38
for level 3: x = 36
because you start by setting an equation like this:
92 + (2x+16) = 180
subtract 92 from both sides, then subtract 16 from both sides, and finally divide both sides by 2 to get 36
Answer:
if the pyramid has a square base and to find a volume you have to find the area of the base(length*width) and multiply that with the pyramid's height and then multiply 1/3 to find the pyramid's volume
Yes. 5/9=0.5 and 5/8=0.6 So yes 5/9 is smaller.
Answer:
Step-by-step explanation:
Given that :
St = the event that person is statistician
E = the event that person is Economist
Sh = the event that person is Shy
a. Briefly explain what key assumption is necessary to validly bring probability into the solution of this problem?
St and E are exclusive events since a person cannot be both statistician and economist.
Key Assumptions:
P(St) + P(E) = 1
Also;
P (St ∩ E) = ∅
b. Using the St. E and Sh notation, express the three numbers (80%, 15%, 90%) above and the probability we're solving for, in unconditional and conditional probability terms.
Given that :
80 % (0.8) of the statisticians are shy and also 15% (0.15) of the economist too are shy; Then :
In the conference; it is stated that there are 90% economist ; Therefore:
P(E) = 0.9
P(St) = 0.1
c) Briefly explain why calculating the desired probability is a good job for Bayes's The- orem
From the foregoing; we knew the probability of and asked to show that P(st|sh) = 0.37 ; Then using Bayes Theorem; we have:
As illustrated above; the required probability was determined using Bayes Theorem; Thus, calculating the desires probability is a good job for Bayes's The- orem.
