Step-by-step explanation:

sec(x) = 1/cos(x)

and therefore, it behaves accordingly.

the minimum of cos(x) is the maximum of 1/cos(x).

it does not have any x-intercepts. for cos(x) = 1 (max) we get 1/1 = 1 for sec(x), which is the minimum.

mirrored to this, cos(x) = -1 gives us also -1 for sec(x).

sec(x) = 1/cos(x) can never have a result between -1 and +1.

cos(0) = 1, so also sec(x) = 1, and therefore (0, 1) is the y-axis intercept.

at every pi (beginning at 0) there is a horizontal tangent, but not an asymptote. the (vertical) asymptotes happen at every pi beginning at pi/2 and -pi/2.

therefore, only the third and fourth answer options are correct.

Suppose the time it takes a barber to complete a haircuts is uniformly distributed between 8 and 22 minutes, inclusive. Let X =

salantis [7]

Answer:

$P(X>14)= 1-P(X$

And replacing we got:

$P(X>14)= 1- \frac{14-8}{22-8}= 0.5714$

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714

Step-by-step explanation:

We define the random variable of interest as x " time it takes a barber to complete a haircuts" and we know that the distribution for X is given by:

$X \sim Unif (a= 8, b=22)$

And for this case we want to find the following probability:

$P(X>14)$

We can find this probability using the complement rule and the cumulative distribution function given by:

$P(X$

Using this formula we got:

$P(X>14)= 1-P(X$

And replacing we got:

$P(X>14)= 1- \frac{14-8}{22-8}= 0.5714$

The probability that a randomly selected barber needs at least 14 minutes to complete the haircut is 0.5714

Masja [62]

Answer:

$28

Step-by-step explanation:

SO,

5.5% OF SOME NUMBER is 1.54 dollars. Right?? Yes!

SOME NUMBER is what we are looking for, that is the ORIGINAL PRICE OF THE BOARD GAME.

We can let original price [some number] be "x" and write the word equation as algebraic equation shown below:

$0.055*x=1.54$

Note: 5.5% = 5.5/100 = 0.055

Now, we just simpyl solve for x:

$0.055*x=1.54\\x=\frac{1.54}{0.055}\\x=28$

$28 is the original price
