Answer:
a.
Step-by-step explanation:
Probability that is a AB type blood given is a Male
P(AB/M) = 42/500 = 21/250
Probability that they are Male with an AB type blood out of all AB type blood people = Probability that is a Male out of all students
P(M∩AB) = P(M)
(42/105) = (500/1,250)
.4 = .4 ✅
The events "the student is male" and "the student has blood type AB" are independent events.
Answer:
88 ft. per sec.
Step-by-step explanation:
X^2 - 16x + 64 =
(x - 8)(x - 8) =
(x - 8)^2
** see ur x term (-16x)....u take half of ur x term, which would be -8, then square it...(-8)^2 = 64...then add that to both sides. Then factor it.
Volumn = Height*Width*Length
Width*(Width+2)=Volumn/Height=240/3=80
Width^2 +2Width-80=0
(Width-8)(Width+10)=0
Width>0 -> Width+10>0
-> Width-8=0 -> Width=8 inches
