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
Answer:
Step-by-step explanation:
hello :
The east edge cannot intersect with the west edge so :
the west edge and The east edge are paralal same slope but the slope for the line y = 2x + 5 is : 2
so : the line could the east edge be located is : y= 2x+b b : no 5
The evaluation of the expression is S equals zero
Answer:
x = 49.84
Step-by-step explanation:
We are given an equation of unknown x and we have to solve the equation for x.

⇒ 
⇒
{Since we know that ln AB =ln A + ln B}
⇒ 
⇒
{Since we know that ln A/B = ln A - ln B}
⇒ 
⇒ 
⇒
{Converting logarithm to exponent form}
⇒ x = 49.84 (Approximate) (Answer)
