A local pizza restaurant delivery time has a uniform distribution over 0 to 60 minutes. What is the probability that the pizza d

Likurg_2 [28]

Answer:

$X \sim Unif (a= 0, b=60)$

And we want to find the following probability:

$P(X>30)$

And for this case we can use the cumulative distribution given by:

$F(x) =\frac{x-a}{b-a}, a \leq x \leq b$

And for this case if we use this formula and the complement rule we have:

$P(X>30)= 1-P(X$

Step-by-step explanation:

Let X the random variable who represent the pizza delivery time and we know that the distribution for x is given by:

$X \sim Unif (a= 0, b=60)$

And we want to find the following probability:

$P(X>30)$

And for this case we can use the cumulative distribution given by:

$F(x) =\frac{x-a}{b-a}, a \leq x \leq b$

And for this case if we use this formula and the complement rule we have:

$P(X>30)= 1-P(X$

Part C<br> How many cubic blocks are needed to fill the fish tank?

nikklg [1K]

Answer:

$2\frac{2}{3}$ cubic blocks

Step-by-step explanation:

The given parameters are:

$Length = \frac{1}{2}yd$

$Width = 16yd$

$Height =\frac{1}{3}yd$

Required

Number of cubic blocks to fill the tank

To do this, we simply calculate the volume of the tank by:

$Volume = Length * Width * Height$

This gives:

$Volume = \frac{1}{2} * 16 * \frac{1}{3}$

$Volume = \frac{16}{6}$

Simplify

$Volume = \frac{8}{3}$

Express as mixed numbers

$Volume = 2\frac{2}{3}yd^3$
