Answer:
24+6pi
Step-by-step explanation:
the sides on the left and right added up are
12+12=24.
the formula for perimeter of a circle is 2πr.
3 is the radius, making the equation
2π3 which is 6 pi.
for the top semicircle, the perimeter would be 6 pi divided by 2 because its a semicircle.
the bottom cut out half would also be 3 pi.
in total, we would have 24+3pi+3pi which would lead you to 24+6pi.
Answer:
3.645
Step-by-step explanation:
4.760-0.015=3.645
2800-2100=700
2800/700=4
4% decrease
Answer:
0.15651
Step-by-step explanation:
This can be approximated using a Poisson distribution formula.
The Poisson distribution formula is given by
P(X = x) = (e^-λ)(λˣ)/x!
P(X ≤ x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to x)
where λ = mean of distribution = 20 red bags of skittles (20% of 100 bags of skittles means 20 red bags of skittles)
x = variable whose probability is required = less than 16 red bags of skittles
P(X < x) = Σ (e^-λ)(λˣ)/x! (Summation From 0 to (x-1))
P(X < 16) = Σ (e^-λ)(λˣ)/x! (Summation From x=0 to x=15)
P(X < 16) = P(X=0) + P(X=1) + P(X=2) +......+ P(X=15)
Solving this,
P(X < 16) = 0.15651
