Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in 3 hours and 6 minutes?

Veronika [31]

Answer:

He will bike 26.87 miles.

Step-by-step explanation:

Given:

Jordan bikes at a speed of 8 2/3 mph.

Now, to find the distance he will bike in 3 hours and 6 minutes.

Speed = $8\frac{2}{3}=\frac{26}{3}\ mph.$

Time = 3 hours and 6 minutes

= $180+6=186\ minutes.$

As, 60 minutes = 1 hour.

= $\frac{186}{60} =3.1\ hours.$

So, to get the distance we put formula:

$Distance=speed\times time$

$Distance=\frac{26}{3} \times 3.1$

$Distance=\frac{80.6}{3}$

$Distance=26.87\ miles.$

Therefore, he will bike 26.87 miles.

Answer:

$z =\frac{50-64}{7}= -2$

$z =\frac{43-64}{7}= -3$

We know that within two deviations from the mean we have 95% of the data from the empirical rule so then below 2 deviation from the mean we have (100-95)/2 % =2.5%. And within 3 deviations from the mean we have 99.7% of the data so then below 3 deviations from the mean we have (100-99.7)/2% =0.15%

And then the final answer for this case would be:

$2.5 -0.15 = 2.35\%$

Step-by-step explanation:

For this case we have the following parameters from the variable number of motnhs in service for the fleet of cars

$\mu = 64, \sigma =7$

For this case we want to find the percentage of values between :

$P(43< X< 50)$

And we can use the z score formula given by:

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

In order to calculate how many deviation we are within from the mean. Using this formula for the limits we got:

$z =\frac{50-64}{7}= -2$

$z =\frac{43-64}{7}= -3$

We know that within two deviations from the mean we have 95% of the data from the empirical rule so then below 2 deviation from the mean we have (100-95)/2 % =2.5%. And within 3 deviations from the mean we have 99.7% of the data so then below 3 deviations from the mean we have (100-99.7)/2% =0.15%

And then the final answer for this case would be:

$2.5 -0.15 = 2.35\%$

OverLord2011 [107]

Answer:

340 customers.

Step-by-step explanation:

1 out of 4 = 25% purchase rate

85 × 4 = 340

To check our work:

25% of 340 = 0.25 × 340 = 85
