Answer:
the answer is 2..............
Answer:
The answer is 71.61%.
Step-by-step explanation:
Households discarding paper week is given to be normally distributed with a mean, 
= 9.4 lb.
The normally distributed distribution has a standard deviation given as 
= 4.2 lb.
The proportion of households that throw out at least 7 lb of paper a week is to be found.
Therefore we have to find p(X ≥ 7) which can be written as
p(X ≥ 7) = 1 - p(X < 7)
= 1 - p( Z < 
)
= 1 - p( Z < 
)
= 1 - p( Z < -0.571 )
= 1 - 0.2839
= 0.7161
Therefore the percentage of households that throw out at least 7 lb paper a week is 71.61%
Answer:
197.2 million
Step-by-step explanation:
The appropriate exponential equation for the population is ...
p(t) = 172.0e^(0.019t)
Then we can compute for t=7.2:
p(7.2) = 172.0e^(0.019·7.2) ≈ 172.0·1.146599 ≈ 197.2
7.2 minutes from now, the population will be about 197.2 million.
___
For continuous growth (or continuous compounding), the exponential formula is ...
f(t) = (value at t=0)×e^(rt)
where r is the growth rate in one unit of time, and t is the number of time periods.
Answer:
slope=4
Step-by-step explanation:
Hello!
Answer:
The amount is-
Cupcakes-12
Chips-18
And the amount that brought drinks are-6
Step-by-step explanation:
18+12
30
18
12
10+10=20
8+2=10
10+10+10=30 and the rest brought drinks.
36-30=6
Hope this helps have a good day! <3
