Answer:

X=125/64

Step-by-step explanation:

x^2+4 x-5=0

x^2+4x=5

4x^3=5

x^3=5/4

x=5^3/4^3

Answer: Choice C) 115 degrees

Focus on the parallel lines G and L, which are the top and bottom most horizontal lines. Notice that the transversal cut forms the alternate exterior angles 2 and 11. The angles are on the outside or exterior of the "train tracks" of the parallel lines. Also, they are on opposite sides of the transversal line. So that is how we can consider them to be alternate exterior angles.

Similar to alternate interior angles, alternate exterior angles are congruent if we have a transversal cutting a pair of parallel lines.

So in short, angle 2 and angle 11 are congruent. We are given angle 2 to be 115 degrees. Angle 11 is also 115 degrees.

Suppose that it is reported in the news that 12% of the people living and working in Kokomo feel that their commute is too long.
Dominik [7]

Answer:

22.3 minutes

Step-by-step explanation:

The computation of the travel time is as follows:

Given that

\mu = 17

And, the standard deviation is 4.5

P(X≤C) = 0.88

P( x - \mu) ÷ \sigma ≤  (C - \mu)  ÷ \sigma  = 0.88

(C - \mu)  ÷ \sigma  = 1.175

c = \mu +  1.175 × \sigma

= 17 + 1.175 × 4.5

= 22.3 minutes

Hence, the travel time is 22.3 minutes
