A game spinner has regions that are numbered 1 through 9. If the spinner is used twice, what is the probability that the first number is a 3 and the second is a 5?
Answers
Final answer:
The probability that the spinner lands on 3 in the first spin and 5 in the second spin is 1 out of 81, given that each spin is independent and the spinner has numbers 1 through 9.
Explanation:
The question is asking about the probability of getting a 3 followed by a 5 on a spinner with numbers 1 through 9. Since the outcomes of spinning are independent, the probability of both events happening is the product of their individual probabilities.
Now, since the spinner has numbers 1 through 9, the probability of landing on any specific number is 1/9. Therefore, the probability of landing on 3 in the first spin is 1/9. In the second spin, the probability of landing on 5 is also 1/9.
To find the combined probability of both these events happening, you need to multiply the individual probabilities together. So, in this case, P(3 and 5) = P(3) * P(5) = 1/9 * 1/9 = 1/81. So the probability of the spinner landing on 3 in the first spin and then 5 in the second spin is 1 out of 81.

The verbal expression 3x ÷ 5 can be described as the quotient of three times some number and five.
An algebraic expression is termed as the mathematical expression that includes two phrases and is connected with an equal sign.
The phrase 3x ÷ 5 means any number that has been multiplied by 3 will be given a quotient when divided by the number 5.
In the expression, the variable x can be assumed with any of the number, and then the expression can be further computed with the calculation of a single variable.
Therefore, the correct option is the first sentence.

18 inches. What is the
circumference of the
basketball hoop?
Answers
The perimeter of the basketball hoop is 18π inches.
The circumference of a circle can be found using the formula:
C = πd
where C is the circumference and d is the diameter of the circle.
In this case, the diameter of the basketball hoop is approximately 18 inches. So we can plug this value into the formula to get:
C = π(18)
Using a calculator or approximating π to 3.14, we can evaluate this expression to get:
C ≈ 56.52 inches
Therefore, the circumference of the basketball hoop is approximately 56.52 inches.
