The correct answer is P = 0.1357.
In solving for the probability (P) that the 34-year olds
will spend more than $60 on fastfood, the mean and the standard deviation is to
be taken into account. The mean (μ) being the $44 average weekly expenditure; while
the standard deviation (σ) is $14.50. The formula goes this way P(X > 60) =
P( X−μ > 60−44 ) = P ( X−μ/σ > 60−44/14.50).

Answer:
71.6056
Step-by-step explanation:
c² = a² + b² - 2abcosC°
29² = 30² + 15² - 2(30)(15)cosC°
841 = 900 + 225 - 900cosC°
-59 = 225 - 900cosC°
-284 = -900cosC°
71/225 = cosC°
cos⁻¹(71/225) = C°
C° = 71.6056
