Answer:
92.65 % light bulbs last less than 2080 hours
Step-by-step explanation:
We are given that The amount of time a certain brand of light bulb lasts is normally distributed
Mean =
Standard deviation =
We are supposed to find What percentage light bulbs last less than 2080 hours, to the nearest tenth

Z=1.45
Refer the z table for p value
p value = 0.9265
Hence 92.65 % light bulbs last less than 2080 hours
1/2(4x-5) + 5/2 = 10
Use the distributive property:
2x - 5/2 + 5/2 = 10
Use addition property:
2x = 10
Divide both sides by 2:
x = 10/2
x = 5
