Answer:
Mean = ∑x + standard deviation = 429.21
Step-by-step explanation:
Mean lifespan = 71.45 years
Standard deviation = 12.35 years
Standard deviation= ∂ = x-µ / N
∂ = standard deviation
µ= mean
x = size of year
By using formula of standard deviation:
= 70 – 71.45 / 12.53
Approximately equal to 64.21
Mean = ∑x + standard deviation
= 365 + 64.21
= 429.21

Mark brainliest please
Hope this helps you
It would take 1/2 hour to get 3/4 mile.
3/4 of a hour to get 1 mile.
I think it would take 1 hour to get 1 1/4 miles
2 hour to get 2 1/4 miles
Hopefully I did correctly.
Hope it helps. :)
Your answer would be ΔAED and ΔCDE
