The manager of a warehouse would like to know how many errors are made when a product’s serial number is read by a bar-code read

er. Six samples are collected of the number of scanning errors: 36, 14, 21, 39, 11, and 2 errors, per 1,000 scans each.
What is the mean and standard deviation for these six samples?

The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers. 
I'm sorry, but I don't know how to do the standard deviation... 
Hope this helped!

A triangle has sides of lengths 16,14 and 50 .is the triangle right angle triangle?​
Debora [2.8K]

Answer:

no

Step-by-step explanation:

using the converse of Pythagoras' identity

If the square on the longest side is equal to the sum of the squares of the other 2 sides, then the triangle is right.

longest side = 50 ⇒ 50² = 2500

16² + 14² = 256 + 196 = 452

since 452 ≠ 2500 then the triangle is not right

Four times the lesser of two consecutive even integers is 12 less than twice the greater number. Find the integers.
pashok25 [27]
Oh, this one lol. ok
you gotta read it like its a book.
4 x s(i picked that variable) which is 4s together

4s+12 (if they said'12 less than' then the 12 gotta be adding.)
then u have to divide it so its going to look like this:

4s+12= blah blah blah
'twice the greater number' means you gotta do this: 2(s+2)

so the problem is this: 4s+12=2(s+2)

now you solved it and the answer will beeeeee s=-4
