aleksklad [387]

Answer:

Speed of Chris Huber = 30.726 m/s

Time taken by Sam = 5.55 s

Step-by-step explanation:

Given:

Distance = 200 m

Time taken by Chris Huber = 6.509 s

Now,

Speed of Chris Huber = $\frac{\textup{Distance}}{\textup{Time}}$

or

Speed of Chris Huber = $\frac{\textup{200 m}}{\textup{6.509 s}}$

or

Speed of Chris Huber = 30.726 m/s

Speed of Sam = Speed of Chris Huber + 19.0 km/h

Now,

1 km/hr = 0.277778 m/s

thus,

19.0 km/h = 19.0 × 0.27 = 5.278 m/s

thus,

Speed of Sam = 30.726 + 5.278 = 36.004 m/s

therefore,

Time taken by Sam = $\frac{\textup{Distance}}{\textup{Speed}}$

or

Time taken by Sam = $\frac{\textup{200}}{\textup{36.004}}$ = 5.55 s

22. Philip has an average daily balance on his credit

Eduardwww [97]

Answer:

$0.81

Step-by-step explanation:

Given;

Philip's average balance = $107.50

Annual Charges rate = 8.99% = 0.0899

The annual Charges can be calculated as;

Annual Charges = Average balance × rate

Substituting the values;

Annual Charges = 107.50 × 0.0899 = $9.66

The monthly charges can be derived from the annual Charges by dividing by the number of months in a year.

Monthly Charges = Annual Charges ÷ 12 month per year

Monthly Charges = $9.66 ÷ 12 = $0.805

Monthly Charge = $0.81

Answer:

$P(X>1000)$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

$P(X>1000)=P(\frac{X-\mu}{\sigma}>\frac{1000-\mu}{\sigma})=P(Z>\frac{1000-950}{50})=P(z>1)$

And we can find this probability using the complement rule and the normal standard table and we got:

$P(z>1)=1-P(z$

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution problem

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

$X \sim N(950,50)$

Where $\mu=950$ and $\sigma=50$

We are interested on this probability

$P(X>1000)$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

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

If we apply this formula to our probability we got this:

$P(X>1000)=P(\frac{X-\mu}{\sigma}>\frac{1000-\mu}{\sigma})=P(Z>\frac{1000-950}{50})=P(z>1)$

And we can find this probability using the complement rule and the normal standard table and we got:

$P(z>1)=1-P(z$
