Answer:

Step-by-step explanation:

To calculate the perimeter we must add the lenghts of the sides :

  • CD=13 USING THE PYTHAGORIAN THEOREM
  • ED=5
  • EF=3
  • BC=14
  • BK=4
  • KH=4
  • GF=9
  • HG≈ 11 USING THE  PYTHAGORIAN THEOREM WE GET 11.2 WICH 11 APPROMATIVELY
  • by ADDIND THESE VALUES WE GET : the perimeter = 63
  • To calculate the area we must divide the shape into 4 parts : 3 rectangles and 1 triangle
  • A1=56
  • A2=30
  • A3=80
  • A4=27

Lettuce is planted on a 46​-acre field. The field is divided into​ one-acre subplots. A sample is taken from each subplot to est
nalin [4]

The correct answer is B. Stratified sampling is​ used since the field is divided into subplots and a random sample is taken from each subplot.

Explanation:

Sampling refers to the process followed by researchers to select a group of individuals from a larger group; considering in most studies it is not possible to analyze all the population. In the case of stratified sampling, this involves dividing the general population into smaller groups, which are known as strata; after this, the researcher selects a specific number of individuals from each strata. This method guarantees the sample is selected randomly, and therefore the study is not biased. Stratified sampling was the method used in the example described because, in this, the general population (46-acre field) was divided into subplots that represent the strata. Also, after this, the researcher selected one random sample.

A group of workers can plant 6 3/4 acres in 1 7/8 days. What is the unit rate in acres per day?
Sedaia [141]

Answer:

The answer is 3.6 acres per day

Step-by-step explanation:

To find the unit rate divide the number of acres by number of days

∴ Unit rate = 6\frac{3}{4} ÷ 1\frac{7}{8}

                  = (6 × 4 + 3)/4 ÷ (1 × 8 + 7)/8 = 27/4 ÷ 15/8

                  = 27/4 × 8/15 = 18/5 = 3.6 acres per day
