Answer:
99.7%
Step-by-step explanation:
Note that 92 and 128 are 3 standard deviations from the mean
The emperical rule or the 68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean
95% of outcomes are within 2 standard deviations from the mean
99.7% of outcomes are within 3 standard devations from the mean
This is 3 standard deviations so the answer is 99.7
A is your answer. Parallel lines never intersect. They both run the same direction, the same distance from each other.

Answer:
<u>18 waves</u> hit the beach in 49 s.
Step-by-step explanation:
Given:
The frequency of the waves that were coming into the beach is 0.367347 Hz.
Now, to find the number of waves that hit the beach in 49 s.
Let the number of waves be 
The frequency of waves (
) = 0.367347 Hz.
The time it takes to hit the beach (
) = 49 s.
Now, we put formula to get the number of waves:
<u><em>The number of waves = 18.</em></u>
Therefore, 18 waves hit the beach in 49 s.
Slope of this line, -5y = -3x - 4
y = 3/5x + 4/5
So, slope of line which is perpendicular = -5/3 [reciprocal & opposite ]
In short, Your Answer would be -5/3
Hope this helps!
