Answer: $8.5
Step-by-step explanation:
i did the work
From the graph, when x = 1, y = 57,000.
Replace x with 1 in the equations and see if any of the Y 's equal 57,000 :
y = -2610.82(1) + 47860.82 = 45,250
y = 219(1)^2 - 6,506.78(1) + 59,385 = 219 - 6506.78 + 59385 = 53,097.22
y = 54041.5(0.9)^1 = 48,637.35
y = 10,504.6 (1.1)^1 = 11,555.06
The second equation is the closest. so try another x value to see if it is close to the Y value:
Let's try x = 14:
y = 219(14)^2 - 6506.78(14) + 59,385 = 42924 - 91094.92 + 59385 = 11,214.08
This is close to Y = 12,00 shown on the graph
SO the closest equitation is y = 219x^2 - 6506.78x + 59385
Answer:
1 / 10 (1 : 10) (10%) - your teacher has probably given you some idea as to the formatting of how you should write probability [so 3 different ways are written here], but I suspect they expect you to write it as 1 / 10
Step-by-step explanation:
only 1 out of all of these 10 trials is a "success" (aka what we are looking for)
we know that 7 matches the criteria of all years seeing a groundhog, and that all other options (1 , 2 , 3 , 4 , 5 , 6 , 8 , 9 , 10) do not meet this criteria.
so, the experimental probability** is 1 / 10 (or 1 : 10) (1 / 10 = 10%)
**: experimental probability is about how many times something happens in the experiment--not theoretically. it means that if his life was destined to be 1 of the 10, the probability of his experience matching the criteria is 1 / 10
experimental probability can be thought of as
successes / possible outcomes

97, 19+(11+37)=19+(48)=67 and then add 30 because of 19 and 11 and you get 97
100 - 3(3y - 4x) = 100 - 3(18 - 16) = 100 - 3(2) = 100 - 6 = 94
