<u>Answer:</u>
Difference between the experimental and the theoretical probability is 2/5 .
<u>Step-by-step explanation:</u>
Spinner is spun 10 times, and experimental probability of landing on a 3 is 1/2, i.e. out of 10 times spinner lands 5 times into 3.
Now, theoretical probability of landing on a 3 is 1/10.
∴ Difference between the experimental and the theoretical probability :
<em> ⇒ (1/2) - (1/10) </em>
<em> ⇒ </em><em>2/5</em>
Like terms are when you have 2 of the same coefficent disregarding the amount of numbers. you can add or subtract them to simplify in other words.
It’s B, -7x is the rate of the water decreasing while 300 is the starting point.
