Answer:
41.5
Step-by-step explanation:
Take the amount of recycled waste and divide it by the total amount of waste. Then multiply this value by 100 to get the percentage of waste which was recycled.
9733/23454 = 0.415
0.415 x 100 = 41.5
The medical researcher's expectation is wrong. There is enough statistical evidence to prove that 25% or more are smokers in the university.
The correct option is a. 550 dm.
The 0.55 hectometers expressed in decimeters are 550 dm.
<h3>What is unit conversion?</h3>
Unit conversion is a multi-step process that involves multiplying or dividing by a numerical factor and, more specifically, a conversion factor.
- The process may also necessitate selecting the appropriate amount of significant digits and rounding.
- Different conversion units are employed to measure various parameters.
- Measuring Temperature
- Measuring Length
- Measuring Capacity
- Measuring Weight
- Conversion of units is defined as the process of converting between different units & measurements of a given quantity using multiplication or division.
- Conversion is the method of changing the amount of one form in terms of mathematics, such as inches to millimeters or liters to gallons.
- Units are used in the measurement of length, weight, capacity, temperature, and speed.

Answer:
see below
Step-by-step explanation:
Starting from the point-slope equation ...
y -y1 = m(x -x1)
Solving for y gives ...
y = mx +(y1 -m·x1)
So, the slope-intercept form equation is fairly easily found:
y = mx +b . . . . where m = m, and b = y1-m·x1
This is the equation we have used for 'b' in the attached spreadsheet.
__
Of course, the formula for slope is ...
m = (y2 -y1)/(x2 -x1)
This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)
__
The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)
_____
I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:
y = mx +b
1. y = 2x -7
3. y = 2/3x +4
8. y = 1/3x -5
9. y = -5/2x +4
