Answer:
a) 720
b) 60$
Step-by-step explanation:
a) each person is served 3 pancakes and there are 240 people, 240 x 3 = 720.
b) Each bag of mix costs 10$ and can make 120 pancakes, but we need 720 pancakes, which means six bags of mix (since 120x6 = 720). Since each cost 10$, 10 x 6 = 60$

Answer:
Standard deviation, ∂ = 64.21 days
Mean = 429.21 days
Step-by-step explanation:
Given:
Mean lifespan = 71.45 years
Standard deviation = 12.35 years
Standard deviation, ∂ = x - µ / N
Where,
∂ = standard deviation
µ = mean life span
x = size of year
x = 70 years
Standard deviation, ∂ = x - µ / N
= 70 - (71.45 / 12.35)
= 70 - 5.79
= 64.21
Standard deviation, ∂ = 64.21 days
Mean = ∑x + standard deviation
∑x = 365
Mean = ∑x + standard deviation
= 365 + 64.21
= 429.21 days
Mean = 429.21 days
