Candance rolled a 6-sided number cube 60 times and recorded the results in the graph above.
a) according to the graph, what is the experimental probability of rolling a 5?
b) according to the graph, what is the experimental probability of rolling a 4?
c) what is the theoretical probability of rolling a 1?
d) what is the theoretical probability of rolling a 3?
answer: conjunction and -20< x < 16 is answer.
it is a conjunction because it is and statement
|x+2|< 18 gives
[since l x-a l < b means x-a lies between -b and b ]
-18< x+2< 18
subtracting 2 in the whole inequality ,we get
-18-2 < x +2-2 < 18-2
-20 < x < 16
we know that 35 milligrams of demerol is to be given to a patient every 4 hours and we have demerol 50 milligrams/milliliter in stock.
to find out the number of milliliters that should be given per dose, we use the simple ratio method.
therefore, 0.7 milliliter of demerol should be given per dose.
answer: $350 +$3x=$1225
