Answer:
- <u>You need to estimate: approximately 0.84</u>
Explanation:
Please, find attached a figure with the complete question, including the probability distribution.
<h2>Solution</h2>The graph does not permit to read exact values, thus you must estimate.
- P(X=6) ≈ 0.03
- P(X=7) ≈ 0.13
- P(X=8) ≈ 0.62
- P(X=9) ≈ 0.14
- P(X=10) ≈ 0.08
P(X ≥ 8) = P(X=8) + P(X=9) + P(X=10)
- P(X≥8) ≈ 0.62 + 0.14 + 0.08 = 0.84

Answer:
Part 1) Vertical line :
Part 2) Horizontal line :
Step-by-step explanation:
Part 1) Write the equation for the vertical line passing through the point (1,-4)
we know that
The equation of a vertical line (parallel to the y-axis) is equal to the x-coordinate of the point that passes through it
so
The x-coordinate is 1
therefore
The equation of the line is
Part 2) Write the equation for the horizontal line passing through the point (1,-4)
we know that
The equation of a horizontal line (parallel to the x-axis) is equal to the y-coordinate of the point that passes through it
so
The y-coordinate is -4
therefore
The equation of the line is
