The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1700 hours and a standard deviation of 45 hours. Using the empirical rule,
what percentage of light bulbs last between 1655 hours and 1745 hours?

o= 4(i) +3

step-by-step explanation:

o is your output value and i is your input value. so, for example, if we stuck 7 in as our input, we would first multiply by 4 ( pemdas ), which equals 28. then we would add 3 to 28, for a total output of 31. this may not be a graph, but, it is a way to solve your formula..

the answer is:

mean: 6

mad: 2.14

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
