Answer:

9.18%

Step-by-step explanation:

First, find the z-score.

z = (x − μ) / σ

z = (18 − 19.6) / 1.2

z = -1.33

Use a chart or calculator to find the probability:

P(Z < z) = 0.0918

Jeremy and Brenda drove their cars in
harkovskaia [24]

Answer: Jeremy drove 84 miles.

Step-by-step explanation:

Let x represent the number of miles that Brenda drove.

If Jeremy drove twice

as far as Brenda, it means that the distance covered by Jeremy would be 2x miles

When they stopped after some time, they were already

126 miles apart. This means that the total distance covered by both of them is 126 miles. Therefore,

x + 2x = 126

3x = 126

x = 126/3

x = 42 miles

The number of miles that Jeremy drove is

42 × 2 = 84 miles

The ending balance after the transactions is; $59.25

<h3>How to determine ending balance</h3>
