Power usage is measured in kilowatt-hours, kWh. After 7 a.m., the power usage on a college campus increases at a rate of 21% per

kumpel [21]

After 7 a.m., the power usage on a college campus increases at a rate of 21% per hour.

t be the number of hours

the power usage increases at a rate of 21% per hour

21% = 0.21, constant rate = 0.21 . So slope = 0.21

Prior to 7 a.m., 15,040 kWh have been used.

At 7.am , power used = 15,040kWh. so our y intercept is 15,040

We use slope intercept form y=mx+b

slope m = 0.21 and b = 15040

power usage , y = 0.21 t + 15040

The university has a daily goal to keep their power usage less than or equal to 100,000 kWh

Power usage is less than or equal to 100,000

So inequality becomes 0.21t + 15,040 <= 100,000

Of the total number of people on a cruise ship, 1/4 or child passengers. 2/5 of the remaining people were crew. There were 1320

Nuetrik [128]

<h2>462</h2>

Step-by-step explanation:

Total number of people on the cruise ship was 1320.

$\frac{1}{4}^{th}$ of the people were child passengers. Number of child passengers = $\dfrac{1}{4}\times (\text{Total number of people})=\dfrac{1}{4}\times 1320=330$

$\frac{2}{5}^{th}$ of the people were crew. Number of people that were crew = $\dfrac{2}{5}\times (\text{Total number of people})=\dfrac{2}{5}\times 1320=528$

Remaining people in the ship constitute the adult passengers.

Number of adult passengers = $(\textbf{Total number of people})-(\textbf{Total number of children})-(\textbf{Total number of crew})=1320-330-528=\textbf{462}$

∴ Number of adult passengers = 462

A company currently has 200 units of a product on hand that it orders every 2 weeks when the salesperson visits the premises. De

disa [49]

Answer: 289 units

Step-by-step explanation:

Given the following :

Inventory (I) = 180

Lead time (L) = 7 days

Review time (T) = 2 weeks = 14 days

Demand (D) = 20

Standard deviation (σ) = 5

Zscore for 95% probability = 1.645

Units to be ordered :

D(T + L) + z(σT+L)

(σT+L) = √(T + L)σ²

= √(14 + 7)5²

= √(21)25

= 22.9

D(T + L) + z(σT+L) - I

20(14 + 7) + 1.645(22.9 + 7) - I

= 420 + 49.1855 - 180

= 289.1855

= 289 quantities
