How to Factor the Trinomial x^2 - x + 1 using the box method?<br><br><img src="https://tex.z-dn.net/?f=x%5E2%20-%20x%20%2B%201"

IRINA_888 [86]

Answer:

x = 1+√3 i/2 and x = 1-√3 i/2

Step-by-step explanation:

Given the expression x^2 - x+ 1, we are to factorize the expression as shown;

x^2 - x+ 1,

using the general formula

x = -(-1)±√1²-4(1)/2(1)

x = 1±√1-4/2

x= 1±√-3/2

x = 1±√3 i/2

Hence the required value of x are x = 1+√3 i/2 and x = 1-√3 i/2

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 5 m

Grace [21]

Answer:

0.35

Step-by-step explanation:

we know that

The formula to use for uniform distribution is equal to

$P( X < x) = \frac{x-a}{b-a}$

where,

b is the upper limit of the distribution which is 5 minutes in this case.

a is the lower limit of the distribution which is 0 minutes in this case.

x is the concerned value which is 1.75 minutes in this case.

substitute the given values

$P( X< 1.75) = \frac{1.75-0}{5-0}=0.35$

That means

The probability that a randomly selected passenger has a waiting time less than 1.75 minutes is 0.35
