Answer:
The probability of missing the first metal-carrying person is P(x≤50)=0.395
Step-by-step explanation:
We define as success to: missing metal carrying detection.
p=0.01
P(x)=
We look for the probability when all metal carring people is detected so x=0
P(x≤50)=1-P(x=0)=
=0.395
Answer:
x : y = 9 : 13
Step-by-step explanation:
Given that
3x - y : x + 2y = 2 : 5
Express the ratio in fractional form, that is
=
( cross- multiply )
5(3x - y) = 2(x + 2y) ← distribute parenthesis on both sides )
15x - 5y = 2x + 4y ( subtract 2x from both sides )
13x - 5y = 4y ( add 5y to both sides )
13x = 9y ( divide both sides by 13 )
x =
y ( divide both sides by y )
=
, that is
x : y = 9 : 13
Answer:
12
Step-by-step explanation:
120 minutes is 2 hours so you just divide 24 by 2 :)
Simply divide 3 by 0.7,

Or ≈ 4.28571 which is ≈ 4 years.
