in 2014 the attendance at jefferson schools fall festival was 650 in 2015 the attendance was 575 what was the percent change
Gnoma [55]

There was 11.54% decrease in attendance.

Step-by-step explanation:

Attendance in 2014 = Old value = 650

Attendance in 2015 = New value = 575

Change = New value - Old value

Change = 575 - 650 = -75

The negative sign indicates a decrease in attendance.

Decrease percentage = \frac{Change}{Old\ value}*100

Decrease\ percent=\frac{75}{650}*100\\\\Decrease\ percent=\frac{7500}{650}\\\\Decrease\ percent=11.538\%

Rounding off to nearest hundredth

Decrease percent = 11.54%

There was 11.54% decrease in attendance.

Someone who knows the remainder theorem help!​
Damm [24]

Answer:

○ D. Yes, x = 12 is a zero of the polynomial.

The quotient is x + 22, and the remainder is 0.

Step-by-step explanation:

On a second thought, I knew something similar to that theorem because factoring them would determine if it has a remainder:

[x - 12][x + 22]

I am joyous to assist you anytime.

* I apologize for the previous answer I gave you.
