Answer:
(7,4)
Step-by-step explanation:
Use the midpoint formula:
(x1+x2/2,y1+y2/2)
Sub in the points
9+5/2,2+6/2
7,4
Final answer:
(7,4)
I think it's frictional force, and if that's not it...then it could be the net force.
Don't really know.
Answer:
(a) m<3 = 103 degrees
(b) m<4 = 77 degrees.
Step-by-step explanation:
A: The sum of the measures of all three interior angles in a triangle always is 180 degrees. Knowing this, we add the two known interior angles, 20 and 57, then subtract that from 180 to get 103 degrees.
B: The measure of an exterior angle is the sum of the two opposite interior angles. So, we add 57 and 20 to get the m<4 = 77 degrees.
About 1407 sharks would be needed to have a margin of error of 0.25
<h3>What is
margin of error?</h3>
Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:

The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:
