Answer:A ratio compares two numbers or two quantities that are measured with the same unit. The ratio of a to b is written a to b,ab,ora:b. ... When a ratio is written in fraction form, the fraction should be simplified. If it is an improper fraction, we do not change it to a mixed number.
Step-by-step explanation:

The probability is 0.9671.
The z-score for this is given by
z = (x - μ)/(σ/√n)
z = (38000-37500)/(1561/(√33)) = 1.84.
Using a z-table (http://www.z-table.com) we see that the area under the curve to the left of, less than, this is 0.9671.
Answer:
114.4
Step-by-step explanation:
421.2
-305.2
114.4
Solve 10x = 4.1 for x. Divide both sides of this equation by 10: x = 4.1 / 10.
x = 0.41
Answer:
The 12th day.
Step-by-step explanation:
Every four days: 4th, 8th, 12th.
Every three days: 3rd, 6th, 9th, 12th.
You just find lowest common multiple of four and three. Which just means the first multiple they share.
Hopes this makes sense!
