Answer:

Measurement error.

Step-by-step explanation:

Measurement Error are the error when there is difference found in true value of data and measured quantity of data. This difference could be found if we are missing some data in the sample.

The error could be reduced by carefully designing the process of data collection and it´s measurement.

Measurement error are classified into two type of error:

  1. Random error.
  2. Systematic error.

Shalnov [3]
Given that he needs to buy some fabric for his wood shop and that each apron is 1/2 feet long and 3 feet wide, this means that the whole fabric that he needs is a total of 4.5 feet long and 27 feet wide. We cannot determine how many pieces of fabric he needs since the measurement of the fabric sold is not specified in the problem.

I need help I don't get I kneed someone to help me step by step please
Alchen [17]
Well first off a term is each of the quantities in a ratio, series or mathematical equation, so every # is a term. And secondly when simplifying you combine the terms that have the same degree, so 3+5 get combines but 7y-3 dont.

a. 3y+2y+y^2+5+y there are 5 terms and the simplified answer is 6y+y^2+5

b. 3y^2+2xy+1+3x+y+2x^2 there are 6 terms and it is already simplified

c. 3xy+5x+2+3y+x+4 there are 6 terms and the simplified answer is 3xy+6x+6+3y

d. 4m+2mn+m^2+m+3m^2 there are 5 terms and the simplifies answer is 5m+2mn+4m^2

Drag each expression to show whether it is equivalent to 3 time times 9 or to 2x3x9​
horrorfan [7]

Answer:

The answers to your questions are given below

Step-by-step explanation:

A. 3 × 9 = 27

B. 2 × 3 × 9 = 54

Next, we shall determine which option will give the same result obtained above.

9 × 3 = 27

9 × 3 × 2 = 54

3 × (4 + 5) = 3 × 9 = 27

(2 × 3) × 9 = 6 × 9 = 54

Therefore,

3 × 9 = 27

9 × 3 = 27

3 × (4 + 5) = 27

2 × 3 × 9 = 54

9 × 3 × 2 = 54

(2 × 3) × 9 = 54

SUMMARY

3 × 9 >>>>>>>>> 2 × 3 × 9

9 × 3 >>>>>>>>> 9 × 3 × 2

3 × (4 + 5) >>>>> (2 × 3) × 9

iVinArrow [24]

Answer:

The scatter plot of the given data is shown below.

Step-by-step explanation:

The given data is

Time (years)               Number of participants

      3                                       22

      6                                       25

      9                                       28

      12                                       14

      15                                       17

      18                                       20

      21                                       15

      24                                       9

In the scatter plot the x-axis represents the time in years and the y intercept represents the number of participants.

The scatter plot of the given data is shown below.

The line represented by y = 3x − 2 and a line perpendicular to it intersect at R(3, 7). What is the equation of the perpendicula
laiz [17]

Answer:

y= -1/3(x) + 8

Step-by-step explanation:

slope of the 1st line = 3

slope of the line perpendicular to the first is its opposite reciprocal, so

slope of the 2nd line = -1/3

now we have a point and the slope of the perpendicular line, so we use the point slope formula to get:

y-7=-1/3(x-3)

y= -1/3(x) + 1 + 7

y= -1/3(x) + 8
