The standard deviation of T is equivalent to 5.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.Mathematically, we can write -[tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]
Given is that a factory process requires 3 steps to finish a product. The steps each have a mean completion time of A = 10 seconds and a standard deviation of O = 5 seconds. The time it takes to complete each step is independent from the other steps.
We can write that -
5 = √∑(x{i} - 10)²/√3
√∑(x{i} - 10)² = 5√3
(√∑(x{i} - 10)²)² = (5√3)²
∑(x{i} - 10)² = 25 x 3
∑(x{i} - 10)² = 75
Now, we can write that -
σ = √(75/3)
σ = √25
σ = 5
Therefore, the standard deviation of T is equivalent to 5.

dozen of one score?
Answer:
1/2 dozen of one score is 30%.

What is the interest earned on $3,000 at a rate of 0.04 for 3 years? (Hint: Use the formula i = prt , where i represents the interest earned, p represents the principal, r represents the rate, and t represents the time.)
$3,360
$3,003.04
$360
$120
Answer:
$360
Step-by-step explanation:
You have to calculate the interest earned on $3,000, at the rate of 0.04 for 3 years.
P= $ 3000, R= 0.04 and t= 3 years.
3000 × 0.04 × 3= $360 (Answer)
Hope that helps
Have a good day :)
Answer:
$360.
Step-by-step explanation:
The interest earned on principal P, at the rate of r for the duration of t years is given by the equation I = Prt ........... (1)
Now, we have to calculate the interest earned on $3000, at the rate of 0.04 for 3 years.
Here, P = $3000, r = 0.04 and t = 3 years.
Hence, from equation (1), Interest earned, I = 3000 × 0.04 × 3 = $360 (Answer)

If 4 cats enter a room and 3 leave how many monkey are in the water?
Answer:
1 monkey because it ate one of the cats
Step-by-step explanation:
Answer:
3 cats in 3corners
Step-by-step explanation:
the question is incorrect the correct question is IN A SQUARE ROOM THERE ARE 4 CATS IN EVERY CORNER?
Hey there !!!!
If you read that there are 4 cats in the room and in front of each cat is another 3 cats, then it might lead you to the answer of 16. This is not correct.
You will have reached this answer if you assumed that there was 3 cats in front of every cat in the corner. That would mean 4 cats in every coner.
You can reach this answer by dissecting each statement in the riddle. The first statement, “In a square room there are 4 cats in every corner of the room,” then we know that the room is square with 4 corners and that there are 4 cats to begin with.
The second statement of the riddle reads “In front of each cat there are 3 cats.” As we already know from the first statement that there are 4 cats in the room, each cat will see the other 3 cats in the other 3 corners of the room.
