Answer:
Answer is 0.5
Step-by-step explanation:
The text implies that the number of traffic accidents determines the number of ambulances required on the road. Hence, 1 traffic accident requires 1 ambulance.
The time slot and time of day remain same in both the text and the question.
The average or mean number of accidents is 1.1
QUESTION: What then is the probability that there is need for exactly 2 ambulances on that road and in that time frame?
In other words, what is the probability that there'll be 2 accidents on that road and in that time frame?
Since the mean number of accidents is 1.1, 2 is above the mean.
Probability of 1.1 accidents is 1, since that's the mean (expected value).
Probability of 2 accidents is 1/2 which is = 0.5
Answer:
it would be (-7,-6)
x=-7, y=-6
Step-by-step explanation:
The answer would be m ≥ 1 or m ≤ 1/3

Hello!</h2>
The answer is C. formulas
<h2>
Why?</h2>
Formulas are laws o conditions that help us when we are solving numerical problems, we use them to relate number/variables in order to found equivalence between what we are calculating and the information we have.
A formula can include constants, variables and always contain an equality, this last one will help us to establish the needed equivalence to solve numerical problems.
Discarding the other given options:
A. decimals: Incorrect, decimals are a type of number which is not whole numbers.
B. graphs: Incorrect, graphs are graphical tools that we can use to show information or data.
D. percentages: Incorrect, percentages are used to show numerical information as a fraction of 100 units.
E. fractions: Incorrect, like decimals, fractions are a type of number which is not whole numbers, fractions are represented by a division of a number into another, representing just a part of a determinate whole number.
Have a nice day!
