The two parallel lines are FL and GK, on the right side of the shape. The other line is perpendicular to them.
Answer:
We know that the total area under the normal curve is 100%. According to the empirical rule of Normal distribution:
Approximately, 68% of data lies within 
standard deviations of mean.
Approximately, 95% of data lies within 
standard deviations of mean.
Approximately, 99.7% of data lies with 
standard deviations of mean,
Therefore, in a normal curve, roughly 95% of all cases fall within plus or minus two standard deviations.
Answer:
C
Step-by-step explanation:
times = 3 and times x = x
So that means that answer is 3+x which is C
Chance of winning $100 = 1/1000
<span>chance of winning $50 = 5/1000 = 1/200 </span>
<span>cost of ticket = -1 </span>
<span>E[x] = 100* 1/1000 + 50* 1/200 -1 </span>
<span>= 0.1 + 0.25 - 1 = -0.65

Shadow:
10 feet long (tree) ... 4 feet long (Javier)
Real situation:
t feet high = ? (tree) ... 5 feet tall (Javier)
If you would like to know what is the estimated height of the tree, you can calculate this using the following steps:
10 * 5 = 4 * t
50 = 4 * t /4
t = 50 / 4
t = 12.5 feet high
Result: The estimated height of the tree is 12.5 feet.
