2 1/4 (2.25) is your answer
To find the probability, you write a fraction with the number of expected outcomes to total possible number of outcomes.
a) Red - 25/100
b) Purple -55/100
c). There is a 25% or 1 in 4 chance to select a red bulb and a 55% or 5 in 11 chance of selecting a purple bulb.
Assuming R and H:
So volume is pir^2 * H = 1500 and H = 1500/(pir^2) while surface area is A= 2pir*H + 2pir^2
A = 2pir(r+h)= 2piR^2 + 2pir*1500/(pir^2)= 2piR^2 + 3000/r
For A to take minimum, get the derivative 4pir - 3000/R^2 and let it be 0
4pir^3 - 3000 = 0
r = cbrt(3000/(4pi)) ≈ 6.20
h = 1500/(pi(6.20)^2) ≈ 12.42
Answer:
20
Step-by-step explanation:
the lowest number they can all muliply to is 20
20 x 1 = 20
5 x 4 = 20
2 x 10 = 20
-2-6i I believe is the answer if not let me know
