Answer:
12 en cada hucha
Step-by-step explanation:
(x+5) + (x-5) = 24
El 5 se cancela
2x= 24
x = 12
Antes de pasar las monedas: (7 en una hucha y 17 en la otra)
12-5 = 7
12 +5 =17
17+7 = 24
Let be the random variable denoting the number of girls that are born. Then has a binomial distribution on babies and probability of getting a girl . The probability we want is
A
=16x²-25
=(4x)²-(5)²
Using formula a²-b²=(a+b)(a-b)
=(4x+5)(4x-5)
the fourth which passed through (0;2)
C
Substitute n = 8 into the explicit rule
= - ×
= - = - 625 → C
