6 1/2 - 3 1/4 = 13 / 2 - 13 / 4 = 26 / 4 - 13 /4 = 13 / 4 is the distance;
Answer:
Step-by-step explanation:
you have 7 reds of 14 total.
the 1st marble has 7 of 14 probability of being red
the 2nd has 6 of 13 of being red
the 3rd has 5 of 12 of being red
multiplying this out you have:
(7/14)*(6/13)*(5/12)=210/2184
THAT will condense down to 5/52 or 9.615%
this does assume not placing the balls back in between draws
if you do put them back in between draws you would have 7 of 14 chance each draw
that would give you by multiplying out
(7/14) * (7/14)* (7/14) = 343/2744
Found it online lol
that condenses to 1 of 8 or 12.5%

Step-by-step explanation:
Answer:
A. Vertical line
Step-by-step explanation:
To identify a relation if it is a function, we conduct a vertical line test on a graph where our graph should hit the vertical line in exactly one point. If we have a vertical line then all its points will hit during the vertical line tesf, thus it is not a fubction.
She should expect 250 marbles after 400 trials.
why:
if 25/40 is green then that means chances of pulling marbles are increasing by 10% their original number.
Also it's 250 because 25 is 63% of 40 and 250 is 63% of 400
