Answer:
\mu = 14.5\\
\sigma = 5.071\\
k = 1.084
Step-by-step explanation:
given that a statistician uses Chebyshev's Theorem to estimate that at least 15 % of a population lies between the values 9 and 20.
i.e. his findings with respect to probability are

Recall Chebyshev's inequality that

Comparing with the Ii equation which is appropriate here we find that

Next what we find is

Thus from the given information we find that

Find the velocity first, the "slope".
m=(y2-y1)/(x2-x1)
m=(95.5-53)/(4-2)
m=21.25 ? Your equations are wrong, I'll double check with another set of points...
m=(350.5-308)/(16-14)
m=21.25 LOL, yep none of your lines has the correct slope.
Anyway...
y=21.25x+b, using any point we can solve for the y-intercept, or "b", (2, 53)
53=21.25(2)+b
53=42.5+b
10.5=b so the distance to the lighthouse as a function of time is:
y=21.25x+10.5
So essentially, you should fire your teacher or burn that book you are using :)

Answer:
8/9
Step-by-step explanation:
10-2/10-1=8/9
slope=8/9
Answer:
No Solutions
Step-by-step explanation:
Step 1:
5x + 9 = 2x + 7 + 3x - 15 Equation
Step 2:
5x + 9 = 5x - 8 Add and Subtract
Step 3:
9 = - 8 Subtract 5x on both sides
Answer:
9 ≠ - 8 9 cannot equal - 8
Hope This Helps :)
