be the cost of one ounce:

3.20

Now we can cross multiply:

3.20

Divide both sides by

3.20

Therefore,

0.20

A test to measure psychotic tendencies was given to a group of 1,000 air force cadets who wished to work in nuclear silos. Any c

Anastaziya [24]

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

= $P(X\geq 64)\\= 1-R(64)\\=1-0.8413\\= 0.1587$

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 $=1000(0.1587) = 158.7$

No of people accepted $= 1000-158.7 = 841.3\\=841$

Approximately we get 840 so option d

What is the answer to 2(x - 5) + 7 = x + 8

Verdich [7]

<span>2(x - 5) + 7 = x + 8
Use distributed property
2x - 10 + 7 = x + 8
Add 7 to -10
2x - 3 = x + 8
Subtract x from both sides
x - 3 = 8
Add 3 to both sides
Final Answer: x=11</span>
