Answer:
Relative frequency of selecting a 2 = 8/50 = 0.16
Relative frequency of selecting a 3 = 14/50 = 0.28
Step-by-step explanation:
When we have a given experiment with given outcomes (such that each time that we perform the experiment, one outcome happens) the relative frequency of a given outcome is the quotient between the number of times that that outcome happened, and the total number of times that the experiment was performed.
Here the experiment is selecting a random number between 1 and 5, and it is performed 50 times.
Out of these 50 times, the outcome "2" appears 8 times.
Then the relative frequency of selecting the number 2 is:
f(2) = 8/50 = 0.16
And of these 50 experiments, the outcome "3" appears 14 times.
Then the relative frequency of selecting the number 3 is:
f(3) = 14/50 = 0.28
Answer:
The slope is 1 and the y intercept is 1
Answer: Average per year for the repairs and maintenance is $273.66
Step-by-step explanation:
She replace the brake pads in the third year for $98 and the preventive maintenance plan cost $723
what did he average per year for repairs and maintenance?
The total cost of repairs and maintenance = 98 + 723 = 821
repairs and maintenance over the first three years
Divide the answer by 3
821/ 3 = 273.67 dollars per year
