Are you able to expand everything first? from there you would be able to combine line terms. basically if you have 3x+2x it would combine to 5x because they have x in them.
F(x) = -9 + 10.3x probably.
It's definitely not the first or last option as they have negative gradients (i.e. negative x-coefficient) and so represent a negative correlation. The data given tells us there is a positive gradient and so a positive correlation.
It could be the second option as the second and third are not so vastly different but I would go for the third because it appears to most closely fit the data pattern.
Answer:
We are assuming the numbers 1 - 6 on the cubes?
If so,
Blue (3, 4, 5, or 6) is 4/6 or 2/3 chance
Green(1,3,5) is 3/6 or 1/2 chance
To get both the P is 2/3 times 1/2
Step-by-step explanation:
The probability that Nathan is not allergic to penicillin is 1 - 0.75 = 0.25.
The probability that Nathan is not allergic to penicillin and the test predicts it is given by:
100/9 is equal to 11.11.
3/5100 is equal to 0.00058824
And 9 3/5 is equal to 5.4( here you multiply 9 by 3 and after you divided the result with 5)
