natita [175]

Answer:

D

Step-by-step explanation:

We calculate the z-score for each

Mathematically;

z-score = (x-mean)/SD

z1 = (1.9-2.1)/0.2 = -1

z2 = (2.3-2.1)/0.2 = 1

So the proportion we want to calculate is;

P(-1<x<1)

We use the standard score table for this ;

P(-1<x<1) = P(x<1) -P(x<-1) = 0.68269 which is approximately 68%

After robbing a bank in dodge city, a robber gallops off at 14 mi/h. 20 minutes later, the marshall leaves to pursue the robber
Morgarella [4.7K]

For this case we have to write the equation of the position of each one.

We have then:

For the robber:

r = 14t

For the marshall :

r = 16 (t- (\frac{20}{60}))

r = 16 (t-\frac{1}{3})

By the time the marshall reaches the robber we have:

14t = 16 (t-\frac{1}{3})

From here, we clear the time.

We have then:

16t - 14t = \frac{16}{3}

2t = \frac{16}{3}

t =\frac{8}{3}

t = 2.7 h

Answer:

it takes the marshall to catch up to the robber about 2.7 hours.
