Answer:
1/8
Step-by-step explanation:
The probability of getting tails on a single flip is 1/2.
Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.
So, your answer will look like this
x
x
; which equals;
1/8
Pretend these are coordinates that you can use to find the slope of the line.
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:
and the slope is 4. Now use one of the points and the slope of 4 to solve for b, the y-intercept:
40 = 4(10) + b so b = 0. The equation of the line then is y = 4x + 0 or just
y = 4x
(10, 40) and (15, 60). Fit these into the slope formula to find the slope of the line you are looking for:
40 = 4(10) + b so b = 0. The equation of the line then is y = 4x + 0 or just
