Answer:
0.14
Step-by-step explanation:
Using the poisson probability relation :
P(x = x) = (λ^x * e^-λ) ÷ x!
From the question ; mean, λ = 5 ; x = 3
Hence,
P(x = 3) = (5^3 * e^-5) ÷ 3!
P(x = 3) = (125 * 0.0067379) / 6
P(x = 3) = 0.8422375 / 6
P(x = 3) = 0.140
1.
which is further simplified to
which is 20.
2.
The tools that were used by ancient mathematicians to make geometric constructions are compasses and straightedges. A compass is a drawing instrument used to draw circles and arcs. The straightedges on the other hand is a tool to check on the accuracy of a straight line.
The answer is first choice.
You take (8x - 6) then add 80 =90 then solve for x
8x-6+80 =90
x= 2
Answer:
A su mamá
= 2937 pesos
A su hermano
= 1566.4 pesos
El resto para ella
= 3328.6 pesos
Step-by-step explanation:
El número total de pesos que cada uno consiguió se calcula como:
Su madre
= 3/8 del total
= 3/8 × 7832
= 2937 pesos
Su hermano
= 1/5 del total
= 1/5 × 7832
= 1566.4 pesos
Sí misma
= El resto
= 7832 - (2937 + 1566,4)
= 7832 - 4503.4
= 3328.6 pesos
