Answer:
Answer:
Step-by-step explanation:
<u>Total number of outcomes:</u>
<u>Number of combinations of getting 6 heads:</u>
- 15C6 = 15!/6!(15-6)! = 5005
<u>Required probability is:</u>
- P(6 heads out of 15 flips) = 5005/32768 = 0.1527... ≈ 15.3%
Correct choice is D
If the parabola line crosses the x-axis twice, then it has two solutions, or the maximum/minimum of it is a point on the x-axis that means it has two solutions as a double root.
Answer:
y = 0x + 9
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
here m = 0 and c = 9, hence
y = 0x + 9
The equation of a horizontal line is normally written as y = 9
with the x- term omitted
