Given that <span>the weights of farmer carl's potatoes are normally distributed with a mean of 8.0 ounces and a standard deviation of 1.1 ounces.
The probability of a normally distributed data between two values (a, b) is given by:

</span>
S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
Step by step
(x - 21)(71)
=(x + - 21)(71)
=(x)(71) + (-21)(71)
=71x -1491
Answer:
15/8
Step-by-step explanation:
The formula for tangent of an angle is the ratio of the opposite side length to the adjacent side length in relation to the angle.
In this case,side OQ is opposite to ∠ P and side QP is the adjacent side to ∠ P
tan ∠ P=15/8
