Given:
μ = 89 ng/ml, population mean
σ = 23 ng/ml, population standard deviation
Random variable, x = 100
To test P(x < 100), calculate the z-score.
z = (x-μ)/σ = (100 - 89)/23 = 0.4783
From standard tables, obtain
P(x < 100) = 0.6838 = 68.4%
Answer: 68.4%
Answer:
H
Step-by-step explanation:
Out of all of the answers provided, H seems like the equation that makes the most sense.

![[480 - (180)] = 300](https://tex.z-dn.net/?f=%5B480%20-%20%28180%29%5D%20%3D%20300)

Make sure you divide 300 sticks by 60 sticks (box max) to get the number of boxes.

So, Mr. Hanson would need to have 5 more boxes in order to get the total amount of 480 sticks.
From that, H would be considered the best equation that Mr. Hanson would use.
Answer:
Step-by-step explanation:The correct answer is:
If you must have the same number of boys and girls in each group, you can have 7 groups.
Explanation:
To do this, we find the Greatest Common Factor (GCF) of 14 and 21. For this, we find the prime factorization of each number:
14 = 2(7)
21 = 3(7)
The only common factor between these two numbers is 7. Thus we can have 7 groups.
(In each group, we would have 14/7 = 2 boys and 21/7 = 3 girls.)
Answer:
52/63
Step-by-step explanation:
Given the expression;
4/7 * 13/9
WE are to take the product
= (4/9)* (13/7)
= (4*13)/(7*9)
= 52/63
Hence the required fraction is 52/63
