n - a number
14. Nine more than the square of a number: n² + 9.
15. Twice the difference between a number and ten: 2(n - 10)
To solve for the P(54,000≤x≤66000) we proceed as follows:
z-score=(x-μ)/σ
μ-60000
σ-4000
thus:
when x=66,000
z-score=(66000-60000)/4000=1.5
P(z≤1.5)=0.9332
when x=54000
z=(54000-60000)/4000
z=-1.5
P(z≤-1.5)=0.0668
thus
P(54,000≤x≤66000)
=P(z≤1.5)-P(z≤-1.5)
=0.9332-0.0668
=0.8664
Answer: 0.8664

Answer:
ill give you a idea to answer the question
Answer:
The only way of getting to 10 using 2x it should mean that x = 5
2 * 5 = 10
