Answer:

9

Step-by-step explanation:

If you draw a segment parallel to a side of triangle that intersects two sides of the triangle, that segment divides the intersected sides into segments of proportional lengths.

9/72 = (3x - 20)/56

1/8 = (3x - 20)/56

3x - 20 = 1/8 * 56

3x - 20 = 7

3x = 27

x = 9

Answer:

x = 9

Step-by-step explanation:

(3x-20)/9 = 56/72

72(3x-20) = 9(56)

216x-1440 = 504

add 1440 to each side

216x = 1944

divide both sides by 216

x = 9

According to a​ report, 67.5​% of murders are committed with a firearm. ​(a) If 200 murders are randomly​ selected, how many wou
kolezko [41]

Answer: The answer is 135 murders.

Step-by-step explanation: The report tells us that statistically 67.5% of murders are committed using a firearm. It follows therefore that in a sample of 200 randomly selected murders, one would expect that 67.5% of those would be by a firearm. \frac{67.5}{100} * 200 = 135.

It would certainly be higher that the expected value based on previous data collected but it would not be unusual because one sample may have a higher than "normal" amount of murders by firearm. Statistics aren't going to be exact for every sample.

Which statement is true using Cavalieri’s principles ?
Kay [80]

Answer:

One of the benefits of Cavalieri's principle is that it allows us to determine the volume of an oblique prism (or oblique cylinder). When dealing with two prisms (or two cylinders), if the base areas are equal and the heights are equal, then the volume is V = Bh regardless of the overall shape.

( i cant see the answers well so estimate to the one that applies)
