#3. the probability of spinning "rock" is 25% or 1/4 so we can use this probability to predict the number of times we would expect to get "rock" in 80 spins as follows:
25% of 80 = .25(80) = 20 So how likely is it we spin 20 'rock' out of 80 spins? At 25%, not very likely..
#4.
A. True
B. True
C. False, the theoretical probability of make make using the spinner is
or about 56%
25% of 80 = .25(80) = 20 So how likely is it we spin 20 'rock' out of 80 spins? At 25%, not very likely..
#4.
A. True
B. True
C. False, the theoretical probability of make make using the spinner is

It is true that the product of two consecutive even integers are always one less than the square of their average.
<u>Step-by-step explanation</u>:
Let the two consecutive odd integers be 1 and 3.
- The product of 1 and 3 is (1
3)=3
- The average of 1 and 3 is (1+3)/2 =4/2 = 2
- The square of their average is (2)² = 4
∴ The product 3 is one less than the square of their average 4.
Let the two consecutive even integers be 2 and 4.
- The product of 2 and 4 is (2
- The average of 2 and 4 is (2+4)/2 =6/2 = 3
- The square of their average is (3)² = 9
∴ The product 8 is one less than the square of their average 9.
Thus, It is true that the product of two consecutive even integers are always one less than the square of their average.
