Karl had planned to drive for 1023 hours on a certain day during his road trip. When he became sleepy, however, he decided to de

netineya [11]

Since Karl became sleepy and decided to decrease his driving time by 25%, he drove <u>767.25 hours</u> that day.

<h3>What is driving time?</h3>

Planned driving time is the estimated time that Karl planned to drive between two points or to one's destination.

The Actual driving time is the actual time that it took Karl to drive from one point to his destination.

Driving time can be estimated or calculated by dividing the distance by the speed.

<h3>Data and Calculations:</h3>

The planned driving hours on a certain day = 1,023 hours

Decrease in driving time = 25%

Percentage of hours Karl drove = 75% (100 - 25)

Hours drove that day = 767.25 hours (1,023 x 75%)

Thus, Karl drove <u>767.25 hours</u> that day.

Y_Kistochka [10]

Answer:

$P(8.6$

And using the normal standard distirbution or excel we got:

$P(-1$

Step-by-step explanation:

Let X the random variable that represent the resistance for resistors of a population, and for this case we know the distribution for X is given by:

$X \sim N(9,0.4)$

Where $\mu=9$ and $\sigma=0.4$

We are interested on this probability

$P(8.6$

And the z score formula is given by:

$z=\frac{x-\mu}{\sigma}$

Using this formula we got:

$P(8.6$

And using the normal standard distirbution or excel we got:

$P(-1$
