0.06597
Step-by-step explanation:
Given that thirty-seven percent of the American population has blood type O+
Five Americans are tested for blood group.
Assuming these five Americans are not related, we can say that each person is independent of the other to have O+ blood group.
Also probability of any one having this blood group = p = 0.37
So X no of Americans out of five who were having this blood group is binomial with p =0.37 and n =5
Required probability
=The probability that at least four of the next five Americans tested will have blood type O+
=
Answer:
D
Step-by-step explanation:
Using the Sine rule in Δ QRS , that is
=
, that is
=
( cross- multiply )
12× sinQ = 15 × sin50.1° ( divide both sides by 12 )
sinQ = , thus
Q = (
) ≈ 73.5° ( to the nearest tenth )
To compare fractions, we need to have the same denominator
The least common multiple is 16
to change
, we should multiply the numerator and denominator by 4
= 
<
so basically, is greater than
which means is greater
is greater
The least common multiple is 16
to change
so basically,
which means
