Answer: $16, 666.67
<u>Step-by-step explanation:</u>
Job 1: 0.06x
Job 2: 0.03x + 500
0.06x > 0.03x + 500
<u>-0.03x </u> <u>-0.03x </u>
0.03x > 500
<u>÷0.03</u> <u> ÷0.03 </u>

x > 16,666.67 <em>rounded to the nearest penny</em>
Answer: P(mean x<18.1077) = P(z< -2.67) = 0.0038
Step-by-step explanation:
Value of Z for 18.1077 = (18.1077 - 19.5)/0.5209 = -2.67

Answer:
98.1°F ≤ x ≤ 99.1°F
Step-by-step explanation:
Given the function:
f(x) = |98.6 - x|
Variance = 0.5
98.6°F - x = ± 0.5
Lower bound :
98.6 - 0.5 ≤ x
98.1 ≤ x
Upper bound :
x ≤ 98.6 + 0.5
x ≤ 99.1
Hence,
98.1°F ≤ x ≤ 99.1°F
