Answer:
2/9 is the correct option.
Step-by-step explanation:
As the spinner is numbered 2, 4 and 5
The general formula for probability :
P(A) = n(A) / n(S)
n(S) is the number of whole states occur in two spins which is 3 × 3 = 9
n(A) is the event that Rico will get a product of 20.
n(A) = 2 ∵ 4 × 5 and 5 × 4 will bring the product 20.
Therefor, the probability that Rico will get a product of 20 when Rico spins the spinner twice will be:
P(A) = n(A) / n(S)
= 2/9
Therefore, 2/9 is the correct option.
A is the answer. It has no repeating x points buy it repeats on the y coordinate, which is okay. The answer is A just to say it again.
Answer:
x=-60
Step-by-step explanation:
convert to x over -6 =10
multiply both side by -6, write as x(-6) over -6= 10(-6)
simplify making x=-60
Answer:
D
Step-by-step explanation:

Answer:
Step-by-step explanation:
6x + 5x + 26.5 + 7x - 8 + 4x+21.5+5x+19+10x+13.5 = 720
37x + 72.5 = 720
37x = 647.5
x = 17.5
Vertices = 105 deg, 114 deg, 114.5 deg, 91.5 deg, 106.5 deg, 188.5 deg
