Answer:
The probability of a bulb lasting for between 480 and 526 hours=0.74454
Step-by-step explanation:
We are given that
Standard deviation of the lifetime,
hours
Mean, 
hours
We have to find the probability of a bulb lasting for between 480 and 526 hours.
Hence, the probability of a bulb lasting for between 480 and 526 hours=0.74454
Answer:
53.14
Step-by-step explanation:
Subtract 0.02 from 0.06 and you get 0.04
Using translation concepts, the transformations are given as follows:
a) The function is horizontally compressed by a factor of 3 and shifted down one unit.
b) The function is shifted right 3 units and vertically stretched by a factor of 2.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
Item a:
The transformations are:
- x -> 3x, hence the function is horizontally compressed by a factor of 3.
- y -> y - 1, hence the function is shifted down one unit.
Item b:
The transformations are:
- x -> x - 3, hence the function is shifted right 3 units.
- y -> 2y, hence the function is vertically stretched by a factor of 2.

Answer:
6
Step-by-step explanation:
12 times 4 = 48
72 - 48 = 24
24 divided by 4 = 6
