Answer:
1. Question isn't complete. It says "Which gives the first two steps to evaluate" and cuts off.
2. Seems like 3.(4-2)2+1 if 3. means to multiply.
3. 9.1=9 should be the answer if . means to multiply.
4. 10x+0=10x
5. x=3 or y=-8
6. x=5 or y=-6
7. Not so sure about this one.
8. 7x/9y
9. 5
Step-by-step explanation:
2. 3.(4-2)2+1
3(2)2+1
6(2)+1
12+1
13
Hey there!

The solution would be like this for this specific problem:
Given:
No
(Did Not Lie) Yes (Lied)
Positive Test Result 10 29
(Positive test indicated that the subject lied.) (false positive) (true positive)
Negative test result 66 18
(Polygraph test indicated that the subject did not lie.) (true negative) (false negative)
Find:
The
probability that all four test subjects had a true negative test result when
they are randomly selected without replacement.
Formula:
(66/123) x (65/122) x (64/121) x (63/120) = 0.0793864272
Therefore, when they are randomly selected without
replacement, the <span>probability that all four test subjects had a
true negative test result is 0.079</span>.
<u>Answer:</u>
P(A') = 0.75
<u>Step-by-step explanation:</u>
We are given that the probability P(A) = 0.25 and we are to determine the probability of the complement of A.
According to the Complement Rule of any probability, the sum of the probabilities of an event and its complement must be equal to 1.
So for for the event A,
P(A) + P(A') = 1
0.25 + P(A') = 1
P(A') = 1 - 0.25
P(A') = 0.75
