Malaria proved that the equation you need to add the parenthesis first
Answer:
La ecuación genérica para un círculo centrado en el punto (a, b), de radio R, es:
(x - a)^2 + (x - b)^2 = R^2
Entonces si miramos a nuestra ecuación:
(x + 2)^2 + (y - 3)^2 = 121
Tendremos el centro en:
(-2, 3)
el radio está dado por:
R^2 = 121
R = √121 = 11

Answer:
a) 0.06048 b) 0.001344 c) 0.000294
Step-by-step explanation:
number of distributors = 10;
number of orders = 7
a)
There are 10 distributors for each order, so the no. of ways the 7 orders could be placed are = 10⁷ =10000000
no. of ways that orders goes to different distributors = ¹⁰C₇*7! = 604800
Probability = 604800/10000000 = 0.06048
b)
number of ways distributor 1 gets exactly 2 and distributor 2 gets exactly 3 orders = ⁷C₂*⁵C₃*8² = 13440
probability = 13440/10000000 = 0.001344
c)
number of ways distributor 1, 2,3 get exactly 2,3 and 1 order(s) = ⁷C₂*⁵C₃*²C₁*7¹ = 2940
probability = 2940/10000000 = 0.000294
No, 4 is a multiple of 80
