You can use it to find the area of a right triangle because a right triangle is basically a rectangle cut in half diagonally. However, this formula does not apply to all triangles because those that are not right triangles don't have a base or height, they're not really a rectangle. Because the formula for a rectangle's area is bxh, a right triangle is half of that. I hope this made sense and was helpful. :)
The correct answer is C. The interquartile range shows us how the middle 50% (from the 25th to the 75% percentile) of the data is spread out.
Answer:
20%
Step-by-step explanation:
If you see they say that the number decreased is 10% each and they say it two times. we could see that the missing number is as big as the length of two 10% together, so if you add them two you get 20%.

When you divide each of them you will notice that C costs the least.
For choice A when you 5 by 3.25 you will get 0.65.
For choice B when you divide 8 by 6.10 you will get 0.7625
For choice C when you divide 12 by 7 you will get 0.5833.....
For choice D when you divide 10 by 6.44 you will get 0.644.
