20 cartons of ice cream = 1 carton of ice cream = $4, meaning that $4 x 20 = $80

2 cartons of yogurt = 1 carton of yogurt = $1, meaning that $1 x 2 = $2

$80 + $2 = $82

Hope this helped!

Determine if \sqrt{3}

gtnhenbr [62]

Answer:

Irrational

Step-by-step explanation:

The square root of 3 is not a perfect square, therefore it is irrational. Another way you could see if it is rational is if it can be put in a fraction, if it can't, then it is irrational.

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
