A rational number are 2 integers
Answer:
0.9885 (98.85%)
Step-by-step explanation:
Since sample is less than 10% of the population, we can use binomial distribution to approximate the probability.
So we want to calculate P( X < 20 ).
We can calculate the probability of complement event P( X = 20 ).
Use binomial formula b(x; n, p) = C( n, x ) p^(x) (1-p)^(n-x)
b( 20; 20, 0.8 )
= C( 20, 20 ) (0.8)^(20) (0.2)^0
= (0.8)^20 ≈ 0.0115
So since P( X < 20 ) = 1 - P( X = 20 ), we have
P( X < 20 ) ≈ 1 - 0.0115 = 0.9885

Answer and Step-by-step explanation:
<u><em>→ Prime factorization of 1624 is :</em></u>
= 2 × 2 × 2 × 7 × 29
<u><em>→ Prime factorisation of 522 is :</em></u><em> </em>
= 2 × 3 × 3 × 29
<u><em>→ Prime factorisation of 1276 is :</em></u><em> </em>
= 2 × 2 × 29 × 11
→

Answer:
y≥0
Step-by-step explanation:
no matter what is written inside it,
|x|≥0
so here
f(x)≥|-x|
so
f(x)≥0
then
y≥0
