we have that
sin(15)=6800/L -------> by opposite side divided by the hypotenuse
solve for L
L=6800/sin(15)
<h2>L=26,273 ft</h2>
It is given that the mean is 79.1 inches and standard deviation is 3.0 inches so it follows:
So the value from 75 to 81 is given by:
Use the table or a software to get the probability values and substitute to get the probability value as:
The probability is 0.6509.
Using sin(A+B) = sinAcosB + cosAsinB
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
sin20cos40 + cos20sin40 = sin(20+40) = sin60degree
=
