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:
the line would move up five units because b is the y intercept, and the y intercept determines the position of the line, not the look or slope of the line
The opposite of 7 is -7, the opposite of -3.5 is 3.5, the opposite of 2.25 is -2.25, and the opposite of 9 1/3 is -9 1/3
Answer:
8. x=-5 and y=7
9. x=-2 and y=0
10. x=-6 and y=-10
11. x=8 and y=-4
12. x=9 and y=-9
13.x=4 and y=10
14. x=5 and y=-7
Step-by-step explanation:
Answer:
50 cm²
Step-by-step explanation:
If you split it like you have done:
10 × (8-5)
= 10 × 3
= 30 cm²
AND
5 × (10-6)
= 5 × 4
= 20 cm²
THEN you have to add both of them together so...
30 + 20
= 50 cm²
I hope this helps and that you have a good day!
