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

Step-by-step explanation:
Answer:
86
Step-by-step explanation:
<h3>22+2²=22+64=86</h3>
x is a variable which in math means an unknown number, since 2+2=4 the answer (If your trying to find what x is) would be x=4.
