The spinner game is an illustration of probability, and the spinner game that is fair is (b) If you spin a number greater than 10, you win.
<h3>How to determine the fair game?</h3>
The number of sections in the spinner is given as:
n = 20
There are 10 numbers greater than 10 i.e. 11 to 2.
So, the probability that a number greater than 10 is spun is:
P = 10/20
P = 0.5
The probability that a number that is not greater than 10 is spun is calculated using the following complement rule
q = 1 - p
This gives
q = 1 - 0.5
Evaluate
q = 0.5
Notice that both probabilities are the equal
Hence, the spinner game that is fair is (b) If you spin a number greater than 10, you win.

Answer:
Lab = 23%
Test 1 = 18.225%
Teas 2= 20.925%
Exam = 25.5%
Total = 87.65%
Step-by-step explanation:
Considering you have the percentages laid out all you have to do is multiply each score with the percentage.
Ok. So first, we need to set up the proportion.
64/8 = x/1
Now, we can cross multiply
64*1 = 8x
64= 8x
8x/8 = 64/8
x= 64/8
Now we have to divide 64 by 8.
x=8
Our final answer: The unit rate is 8 ounces per cup.
The common difference is 19-7 = 31-19 = 12, so this is an arithmetic sequence. The initial term (when n=1) is 7.
The explicit formula for the terms of an arithmetic sequence is
an = a1 + d(n-1)
where "a1" is the first term and "d" is the common difference. The formula that matches a1=7 and d=12 is
B. a(n) = 7+(n-1)·12
Answer:
B
Step-by-step explanation:
Think of it like a quarter you got a half and half shot if getting heads or tails. meaning a 50/50 chance.
