Answer:
4
Step-by-step explanation:
I did 60,000 divide by 30 days equal 2000
2000 divide by 500 equals 4
Answer:
x = 5
Make sure to start right to left.
I think you do
5c=120
5c/5 120/5 =24
you need to get c by itself so divide 5 . When you divide 5 by one side do it to the other
120/5=24
3. Answer 24
Answer:
0.066
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation
For the question
mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg.
x = 2.5
Hence:
z = 2.5 - 3.27/0.51
z = -1.5098
Probability value from Z-Table:
P(x ≤ 2.5) =P(x < 2.5) = P(x = 2.5) =
=0.065547
Therefore, the proportion of baby boys that are born with a low birth weight is 0.066
