Answer:
The Experimental Probability of the spinner stopping on Section A is 1/3.
Step-by-step explanation:
Number of time spinner landed on section A = 4
Number of time spinner landed on section B = 5
Number of time spinner landed on section C = 2
Number of time spinner landed on section D = 1
Total Number of spins = 12
Therefore, The Experimental Probability of the spinner stopping on Section A is 1/3.
Answer:
any number greater than -2
Step-by-step explanation:
4 - 5y < 14
step 1: subtract 4 from each side "
4 - 4 cancels out
14 - 4 = 10
now we have -5y < 10
step 2: divide each side by -5
-5y/-5=y
10/-5=-2
( IMPORTANT NOTE: WE MUST FLIP THE INEQUALITY SIGN IF WE DIVIDE BY A NEGATIVE NUMBER)
We would be left with y > -2
Answer:
Step-by-step explanation:
Total students = 120
Number of students studying Mathematics P(A) = 90
Number of students studying Science P(B) = 72
Number of students who doesn't study both subjects P(AUB)'= 10
1) Number of students studying atleast on subject = 120 -10 = 110
2) Number of students studying both math and science = (90 +72) -110
= 162 -110 = 52
3) Number of students studying only mathematics = 90 -52 = 38
4) Number of students studying only science = 72 -52 = 20
