Answer:
3/2-u
Step-by-step explanation:
You need to break the question down by seeing that is it asking for u less than something so that means subtraction. You then see the quotient of 2 and 3 so then you put 3 over 2 to divide and then put your subtract 2 onto it
Answer:
False
it would be 3 to the 7th power 3⁷
Answer:
0.00621
Step-by-step explanation:
We solve the above question using the
Z score formula. This is given as:
z = (x-μ)/σ/√n
where
x is the raw score = 12.20 or earlier
This means x ≤ 12.20
μ is the population mean = 13.20
σ is the population standard deviation = 2
n is the random number of samples = 25
z = 12.2 - 13.2/2/√25
z = -1/2/5
z = -1/0.4
z = -2.5
Probability value from Z-Table:
P(x≤ 12.2) = 0.0062097
Approximately = 0.00621
Therefore, the probability of randomly selecting a sample of 25 children who stood on their own by the average age of 12.2 months or earlier is 0.00621
