Answer:
Option d) 840
Step-by-step explanation:
Given that a test to measure psychotic tendencies was given to a group of 1,000 air force cadets who wished to work in nuclear silos.
If Score ≥64 would be eliminated.
X is N(52, 12)
Probability for any random person to get eliminated
=
Now coming to sample size of 1000 people, we find each person is independent of the other and there are two outcomes either >64 or < 64
So Y no of persons who get more than 64 is binomial with n =1000 and p = 0.1587
Mean of Y = E(Y)
= no of people who were not accepted
No of people accepted
Approximately we get 840 so option d
Both 25x and 22x + 9 have the same answers. So you set those two equal to each other.
Subtract 22x from both sides.
and you're left with this.
Next, divide 3 from both sides.
re-insert 3 into one of the equations.
add up both angles
all angles (for quadrilaterals)added up equals 360.
solve for x. Subtract 150 from both sides.
and divide 2 from both sides
AngleLMN= 105
Subtract 22x from both sides.
and you're left with this.
