The answer for the spinner would be 1/2 because there are 4 R’s out of 8 so it would be 4/8 which simplifies to 1/2
The answer for the second one I’m sure would be .45 since rolling a one would add up to 9 and the total times it was rolled is 20 so if she rolls again she would have .45 since that’s the answer to 9/20
Hope this helps !

Answer:
80% decrease
Step-by-step explanation:
A percentage change can be calculated using ...
percent change = ((new value)/(old value) -1) × 100%
= (16/80 -1) × 100%
= -0.80 × 100% = -80%
The minus sign indicates the change was a decrease.

Answer:
-16 - 30i
Step-by-step explanation:
(3-5i)^2 = (3-5i) * (3-5i)
Applying the "FOIL" method of expanding this expression through multiplication, we get:
9 - 15i - 15i - 25 (since i^2 = -1)
Simplifying this result, we get -16 - 30i
