8(-1)4 - (3) (-1) -7
=(8)(1) - (3)(-1) - 7
=8 - (3)(-1) - 7
=8-(-3)-7
=11 - 7
= 4

Fatima paid for 5 pallets of grass to be delivered each pallet cost $129.95. Fatima paid $76.20 for delivery. What is the total

lianna [129]

Answer:

$725.95

Step-by-step explanation:

First, calculate how much she paid for the 5 pallets

Each pallet costs 129.95, and she paid for 5, so we can multiply the 2 numbers

129.95*5=649.75

Then, add the delivery cost

649.75+76.20=725.95

So the total amount she paid is $725.95

Hope this helps! :)

Suppose u1, u2, ..., un are independent random variables and for every i = 1, ..., n, ui has a uniform distribution over [0, 1].

sattari [20]

$Z=U_{(1)}=\min\{U_1,\ldots,U_n\}$

has CDF

$F_Z(z)=1-(1-F_{U_i}(z))^n$

where $F_{U_i}(u_i)$ is the CDF of $U_i$ . Since $U_i$ are iid. with the standard uniform distribution, we have

$F_{U_i}(u_i)=\begin{cases}0&\text{for }u_i$

and so

$F_Z(z)=1-(1-F_{U_i}(z))^n=\begin{cases}0&\text{for }z$

Differentiate the CDF with respect to $z$ to obtain the PDF:

$f_Z(z)=\dfrac{\mathrm dF_Z(z)}{\mathrm dz}=\begin{cases}n(1-z)^{n-1}&\text{for }0$

i.e. $Z$ has a Beta distribution $\beta(1,n)$ .

Owning a small and successful business isn't easy! There is a monthly cost of shipping supplies and

Answer:

$C(x)=24,000+19,200x$

Step-by-step explanation:

<u>Mathematical Modeling</u>

To model a real-life situation, a mathematical model can be constructed in such a way it accurately represents the variables measured in the system.

This problem requires to build a model for the yearly cost of a small and successful business.

The first data is the fixed monthly cost or the money the owner must pay regardless of the number of employees he hires. This cost includes shipping supplies and products for $2,000. To operate for a full year, the fixed cost is 12*$2,000=$24,000.

The other component of the cost function is the variable cost of x employees. Given each employee costs $1,600 each month, having x employees cost 1,600x each month. For a full year, the variable cost will be

12*1,600x=19,200x.

We finally form the total cost function:

$\boxed{C(x)=24,000+19,200x}$
