16a. 21cm. bc when it has 10 grams it moves half of that to 5cm so divide 42 by 2 and you get 21cm
17. remember y=mx+b; m is slope and b is y-intercept
you have to put your equation from point slope to y=mx+b
4x+y=6
subtract 4x from each side
y=-4x+6
slope = -4
y-intercept= 6
hope this helped :)
The first sampling method is Convenient Sampling. It is biased sampling and it is not representative of a random sample.
The second sampling method is Systematic Sampling. If this method of sampling is drawn from the population, it is an efficiently randomized sampling method.
Let us review the given answers.
1. Both samples should be exactly the same.
INCORRECT
2. Neither sample will be representative.
Because the second sampling method can be random, this answer is
INCORRECT.
3. The first sampling method, ..., is the most representative,
INCORRECT
4. The second sampling method, ..., is the most representative.
CORRECT

Answer:
The area of that bedroom in real life is of 216 square feet.
Step-by-step explanation:
Real dimensions:
One of the bedrooms on the blueprint is a rectangle measuring 3 inches by 4.5 inches.
The scale is that each inch on the drawing represents 4 feet in real measure.
So the dimensions of the bedroom are:
3*4 = 12 feet by 4.5*4 = 18 feet.
What is the area of that bedroom in real life?
Rectangular bedroom, so the area is the multiplication of the dimensions.
12*18 = 216 square feet.
The area of that bedroom in real life is of 216 square feet.
