Hello,
answer B
f(-4)=-3*(-4)-7=12-7=5
It takes 5 minutes per square foot (400/180=5) and so 5 minutes per square for 720 squares: 720x5=3,600. 3,600 minutes is equivalent to 60 hours so it takes him 60 hours.
Answer:
the expected value= $90
Step-by-step explanation:
when sell is $600 an average of 1 in 100 will claim $20,000
and an average 1 in 200 will claim $30,000
and an average of 1 in 500 will claim $550,000.
company sells 20,000 policies
The expected profit loss can be written as
= 600 - (1/100 * 20000) - (1/200 * 30000) - (1/500 * 80000)
= 600 - 200 - 150 - 160
= 90
Therefore, the expected value= $90

Answer:
x different from 2
Step-by-step explanation:
The function is written as the quotient:
that can give us a real value for any value of x except for x=2 that creates a ZERO in the denominator, making the division undefined.
So the only value for which the function cannot be evaluated is x=2, therefore the function's domain is all the real numbers except for x=2.
