Answer:

24 ft²

Step-by-step explanation:

AC = 10-(3+3)= 4

AB = 12- (3+3) = 6

AB×AC = 6×4 = 24 ft²

To rent a moving truck there is a fee of $150 and each mile you drive costs an extra $1.75 per mile, where R(x) is the total cos

abruzzese [7]

Answer:

$318

Step-by-step explanation:

First, we want to set up an equation to solve this problem by using the information given to us. We're asked for the total cost, so we want one side of the equation to be $R(x)=$ . Then, we know that the initial cost is $150, no matter how many miles we drive. We are also told that each mile is $1.75.

$R(x)=150+1.75x$

The problem tells us that we are driving 96 miles, so we can plug in 96 for $x$ and solve.

$R(x)=150+1.75(96)\\R(x)=150+168\\R(x)=318$

The total cost of the rental is going to $318.

Hope this helps!

Answer:

a) $P(X$

And we can find this probability using the normal standard table:

$P(z$

b) $P(X>48)=P(\frac{X-\mu}{\sigma}>\frac{48-\mu}{\sigma})=P(Z>\frac{48-46.8}{1.75})=P(Z>0.686)=1-P(z$

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

$P(Z>0.686)=1-P(z$

c) $P(46.8-1.5*1.75$

And we can find this probability with this difference:

$P(-1.009$

And in order to find these probabilities we can use the tables for the normal standard distribution, excel or a calculator.

$P(-1.009$

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".

Assuming the following questions:

Part a: What is the probability that the maximum speed is at most 50 km/h?

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

$X \sim N(46.8,1.75)$

Where $\mu=46.8$ and $\sigma=1.75$

We are interested on this probability

$P(X$

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:

$P(X$

And we can find this probability using the normal standard table:

$P(z$

Part b: What is the probability that maximum speed is at least 48 km/h?

$P(X>48)=P(\frac{X-\mu}{\sigma}>\frac{48-\mu}{\sigma})=P(Z>\frac{48-46.8}{1.75})=P(Z>0.686)=1-P(z$

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

$P(Z>0.686)=1-P(z$

Part c:What is the probability that maximum speed differs from the mean value by at most 1.5 standard deviations?

$P(46.8-1.5*1.75$

And we can find this probability with this difference:

$P(-1.009$

And in order to find these probabilities we can use the tables for the normal standard distribution, excel or a calculator.

$P(-1.009$
