Answer:
0.053
Step-by-step explanation:
This is a geometric distribution problem.
I'm geometric distribution problem,
E(X) = 1/p
Where;
E(X) is expected value and p is probability of success
Thus;
1/p = 12.5
p = 1/12.5
p = 0.08
Now, to find the probability that the sixth person tested is the first one with high blood pressure, we will use the probability formula in geometric distribution which is;
P(X = k) = qⁿ•p
q = 1 - p
q = 1 - 0.08
q = 0.92
Thus;probability that the sixth person tested is the first one with high blood pressure will be expressed as;
P(X > 5) = (0.92^(5)) × 0.08
P(X > 5) = 0.053
Answer:
Length * Height * Width, or V = L * H * W. Ex: V = 5 in.
the best would be 1.75
Step-by-step explanation:
3/4 turned into a decimal is .75 then you would add the 1 making it 1.75.
Victoria’s printer can print 8.804 in one minute if Victoria’s prints page for 0.903 minutes,
We apply unitary method
In one minute the number of pages printed is 8.804. we need to find the number of pages for 0.903 minutes
1 minute = 8.804 pages
0.903 minutes = ? pages
We multiply 8.804 by 0.903
8.804 * 0.903 = 7.95
Number of pages printed = 7.95 pages
Answer:
1716 ways
Step-by-step explanation:
Given that :
Number of entrants = 13
The number of ways of attaining first, second and third position :
The number of ways of attaining first ; only 1 person can be first ;
Using permutation :
nPr = n! ÷(n-r)!
13P1 = 13! ÷ 12! = 13
Second position :
We have 12 entrants left :
nPr = n! ÷(n-r)!
12P1 = 12! ÷ 11! = 12
Third position :
We have 11 entrants left :
nPr = n! ÷(n-r)!
11P1 = 11! ÷ 10! = 11
Hence, Number of ways = (13 * 12 * 11) = 1716 ways
