The total number of chairs is the product of the number of rows with the number of chairs per row. You can determine this using the dimensional analysis approach. The solution is as follows:

Number of chairs = Number of rows * Number of chairs/row

Since the the unit 'row' appears on both the numerator and denominator side, they will cancel out, leaving us with the number of chairs.

225 chairs = x*x = x², where x is the number of rows which is also equal to the number of chairs per row

x = √225 = 15

Thus, there are 15 rows with 15 chairs each row.

How many triangles can be constructed with angles measuring 10º, 80º, and 90º?
Feliz [49]
The answer is A. more than one, because you can create one, but then you can move the angles around. So if the angles in order go 10°, 80°, 90°, you could change the order to 90°, 10°, 80°, or something. I hope this helps!

Find the z-scores that bound the middle 74% of the area under the standard normal curve.
aniked [119]

Since 74% of the middle area is bounded, this means that there is 13% on the left side, and another 13% on the right side.

P (left) = 0.13

P (right ) = 1 - 0.13 = 0.87

 

At this P values, the z scores are approximately:

z score (left) = -2.22

<span>z score (right) = 1.13</span>
