If |x| = 2 does X = 2 or x = -2? What is the solution to x = -2?

1 answer:

7 0

Both solutions are x = 2 and x = -2 are correct

because
when x = 2 , |2| = 2
and
when x = -2, |-2| = 2

hope it helps

Answer: 0.49668352

Step-by-step explanation:

Given : The unemployment rate : p = 20%= 0.20

Sample size : n =8

Let x be the binomial variable that represents the number of unemployed residents.

Binomial probability distribution formula : $^nC_xp^x(1-p)^x$

The probability that at least two of the residents were unemployed :

$P(x\geq2)=1-P(x$

$1-(^8C_0(0.2)^0(0.8)^8+^8C_1(0.2)^1(0.8)^7)$

$1-((1)(0.16777216)+(8)(0.2)(0.2097152))$

$1-(0.16777216+0.33554432)$

$1-(0.16777216+0.33554432)=1-0.50331648=0.49668352$

Hence, Required probability =0.49668352
