Answer:
I. 60%
II. 75.4 kg
Step-by-step explanation:
We will use the z-scores and the standard normal distribution to answer this questions.
We have a normal distribution with mean 69 kg and variance 25 kg^2 (therefore, standard deviation of 5 kg).
I. What percentage of adult male in Boston weigh more than 72 kg?
We calculate the z-score for 72 kg and then calculate the associated probability:

II. What must an adult male weigh in order to be among the heaviest 10% of the population?
We have to calculate tha z-score that satisfies:

This happens for z=1.28 (see attachment).
Then, we can calculate the weight using this transformation:

lolololololollololollololollol
So on one die has six numbers, the probability of rolling a 3 on one die is 1/6. So for two die, it would be 1/6 times 1/6= 1/36...
Step-by-step explanation:
Riverside Bakery charges $2 for each cupcake, plus $59 for the large cake.
The Sweet Shoppe charges $38 for the large cake and $3 for each cupcake.
(riverside)
$59 + $2(30) =$119
(sweet shoppe)
38 + $3(30) =$128
riverside bakery is cheaper
Its 80 because if you find perfect square around the number 80 you'd get
√64 and √81
which would be 8 and 9
