Answer:
90050+10x; At least 85 hours
Step-by-step explanation:
Nick must make at least 900 dollars, so the amount he has + earns must be greater than or equal to 900 in order to walk out of the store with it.
50 is the amount that Nick already has, and add that to 10x, which gives $10 for every x hour.
To solve, subtract 50 from each side.
85010x
Divide by 10 to solve for x:
85x
Nick must work at least 85 hours.
(1)
We know that
probability = ( number of favourable outcomes)/( total number of possible outcomes)
and
number of favourable outcomes is always less than or equal to total number of possible outcomes
so, maximum value of probability is 1
and it's minimum value is 0
so, we get
so, option-D.........Answer
