To find the perimeter of a rectangle you can multiply the length by 2 and the width by 2, or you can add the four sides together.
The wrong equation is w + 3w = 90 because it only has one width and one length, which would be half the total perimeter.
Because 1 * 21 = 3 * 7 ( 21 = 21 ) , 1/3&7/21 form a proportion.
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
