-9xy^5 × 9x^2y
-(9 × 9)xx^2y^5y
-81xx^2y^5y
-81x^3y^6
Let’s solve the equation
0.5(5x+1) = 3
= 2.5x + 0.5 = 3
= 2.5x = 3 - 0.5
= 2.5x = 2.5
= x = 1

Answer:
The sample size must be approximately 211.
Step-by-step explanation:
We are given the following in the question:
Sample mean, = 654.1
Alpha, α = 0.02
Population standard deviation, σ = 311.7
Margin of error = 50
Formula:
Putting all the values, we get,
Thus, the sample size must be approximately 211.
