Answer:
x=30
Step-by-step explanation:
1 / 2 ( x + 6) = 18
Distribute
1/2x +3 = 18
Subtract 3 from each side
1/2x +3-3 = 18-3
1/2x = 15
Multiply each side by 2
1/2x*2 =15*2
x = 30
The factors of expression
are (x+6) and (2x-9).
The given expression is: 
<h3>What is a factor?</h3>
A factor is a number that divides another number leaving no remainder.
We can rewrite the given expression as:
(middle term has been splitted)
Take 2 as common from first two terms while take -9 as common from last two terms.

Take (x+6) as common

So, we got the factors (x+6) and (2x-9)
Therefore, The factors of expression
are (x+6) and (2x-9).

Answer:
Probability=0.8413
So option A is correct.
Step-by-step explanation:
In order to find the probability that the criminologist will classify all of them as delinquents, we will proceed as following:
We are required to find:
P(m>=75|m-N(80,5))
it can be written as:
1-P(m<75|m-N(80,5))
P(m<75|m-N(80,5)) can be solved as
Z=(75-80)/5
Z=-1
Probability = 1-Z(-1)
Fromm distribution table:
Probability=1-0.15866
Probability=0.8413
So option A is correct.
