Answer:

2.5

Step-by-step explanation:

We have that the standardized mortality ratio (SMR) is the relationship between the number of deaths observed in a year, that is, those that occurred and the number of expected deaths, that is, those that were predicted.

SMR = observed / expected

therefore if we replace we have:

SMR = 4500/1800

SMR = 2.5

Which means that the standardized mortality ratio (SMR) is 2.5

The area of a quarter circle is 38.465 square<br> inches. What is the quarter circle's radius?

LuckyWell [14K]

The formula for a circle's area is $A=\pi r^2$ . We are given an area of 38.465 square inches for a quarter of it.

Multiply this value by 4 to compensate for the quarter circle.

$4 \times 38.465=\pi r^2$

$153.86=\pi r^2$

Divide both sides by pi (Note: I'm using the conventional value of 3.14)

$49=r^2$

Take the positive square root of both sides

$7=r$

The radius is 7 inches. Let me know if you have any questions, thanks!
