Step-by-step explanation:
Answer:
n = -2
Step-by-step explanation:
6n = 2n-8
4n = -8
n = -2
It is 22 cuz 5 * 2 is 10 and 10 * 2 IS 20 + 2=22
Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-

, where
= Sample mean ,
= population mean,
= population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,

Hence, the z-score = 2.46
As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.
For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.
So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.
